Position the sway bar link onto the lower A-arm and the sway bar. Install the cap screws and lock nuts. Tighten the lock nuts to 23 ft-lb. Brake System Checking Brake Fluid 1. With the brake fluid reservoir in a level position, check the fluid level. The brake fluid level must be just below the high mark. 0747-094 2. Install the spindle axle into the spindle; then position the ski damper into the bottom of the ski making sure the damper is properly positioned for the desired ski stance. NOTE: The ski damper must be positioned in the ski so it is directly under the spindle. 3. With the cap screw hole of the ski centered with the spindle axle, slide the cap screw with washer through the outside of the ski and spindle assemblies. NOTE: Local laws and/or regulations as to maximum width of the ski stance may be applicable. Always comply with the maximum width laws and/or regulations when adjusting ski stance. NOTE: Install the cap screw so the lock nut will be located to the inside of the ski and the cotter pin slot in the cap screw will be horizontal with the ski. SNO-253 2. If the brake fluid level is below the low mark, remove the reservoir cover and add Arctic Cat approved brake fluid until the fluid level is just below the high mark. Install and secure the reservoir cover. Do not allow moisture to contaminate the brake system. 4. Install the remaining washer and lock nut; then tighten the lock nut to 35 ft-lb. NOTE: Assure that the cotter pin slot in the cap screw is still horizontal with the ski (see illustration); then proceed to step 7. 5. Install the cotter pin from the back side of the ski cap screw and spread the pin. NOTE: Repeat this sub-section on the opposite side. CAUTION Brake fluid is highly corrosive. Do not spill brake fluid on any surface of the snowmobile. ! WARNING Do not overfill the brake fluid reservoir. Overfilling the reservoir may cause the brake system to hydraulically lock. Use only Arctic Cat approved brake fluid. Checking Brake Lever Operation Sway Bar 1. Test the operation of the hydraulic brake system by compressing the brake lever. 2. The brake lever must feel firm when compressed. Ski Alignment Checking Toe-Out Range 0.0 - 12.7 mm (0 - 1/2 in.) NOTE: Track tension and alignment must be properly adjusted prior to checking or adjusting ski alignment. Ski alignment must be performed on a flat, level surface. Ski toe-out must fall within the specified range. SNO-2232 1. Place the sway bar into position (mounting location) of the chassis. 2. Secure the bar with the two mounting brackets, four machine screws. 18 1. Raise the front end of snowmobile just high enough that the ski shocks are fully extended but the skis are still resting on the floor. 2. From the riding position on the snowmobile, check that the handlebar is in a straight-forward direction for driving. NOTE: Steering can be centered in the chassis by taking measurements from each side of the drag link to a location on the chassis which would be of equal distance from each side of the drag link. 3. Using a very light hold-down strap (bungee cord) between the ski handles, apply a very light load approximately 2-4 lb pulling the skis together just enough to pull the slack. NOTE: Track tension and alignment must be properly adjusted prior to placing the straightedge against the outside edge of the track. 4. Place a long straightedge against the outside edge of the track so it lies near the inside edge of the left-side ski. 7. Measure the distance from the straightedge to the right-side ski edge in two places: 35.5-38.1 cm (14-15 in.) in front of the spindle and 35.5-38.1 cm (14-15 in.) behind the spindle. Record the measurements taken for the right side. ! WARNING The measurement from the front and rear of ski to the straightedge can be equal (ski parallel to the track), but the front measurement must never be less (ski toed-in) or poor handling will be experienced. The front measurements to the straightedge must not exceed the rear measurements to the straightedge (ski toed-out) by more than 12.7 mm (1/2 in.). 8. If ski alignment is not as specified, adjust the alignment of the ski(s) not parallel to the straightedge. Adjusting NOTE: The following procedure can be used to adjust the alignment of either ski. 1. Unlock the steering tie rod by loosening jam nuts (A). NOTE: The inside jam nuts are left-hand thread. Care should be taken to rotate them in the proper direction. 729-887E NOTE: The straightedge should be long enough to extend from the back of the track to the front of the ski. 5. Measure the distance from the straightedge to the left-side ski edge in two places: approximately 35.5-38.1 cm (14-15 in.) in front of the spindle and 35.5-38.1 cm (14-15 in.) behind the spindle. Record the measurements taken for the left side. SNO-2233A 2. Adjust ski alignment by rotating the tie rod with a wrench at hex-point (B). 3. When ski alignment is correct, apply blue Loctite #243 to the jam nut threaded area and tighten to 20 ft-lb. Tighten both jam nuts against the tie rod. ! WARNING Neglecting to lock the tie rod by tightening the jam nuts may cause loss of snowmobile control and possible personal injury. NOTE: To allow equal rotation of the tie rod end ball joints, secure the tie rod jam nuts with the tie rod ends positioned 90° from each other. 729-887D 6. Place the straightedge against the outside edge of the track so it lies near the inside edge of the right-side ski. 19 Also, if the snowmobile is to remain on a trailer after filling the gas tank, the bed of the trailer must be maintained level to prevent gasoline from draining out through the gas tank vent hose. ! WARNING Always fill the gas tank in a well-ventilated area. Never add gasoline to the snowmobile gas tank near any open flames or with the engine running. DO NOT SMOKE while filling the gas tank. Do not sit on the snowmobile without first installing the gas tank cap. 0743-088 Recommended Gasoline CAUTION Do not use white gas or gasolines containing methanol. Only Arctic Cat approved gasoline additives should be used. The recommended gasoline to use in this snowmobile is minimum 91 octane gasoline with a maximum 10% ethanol content. NOTE: For optimum performance, use only 91 octane (minimum) gasoline. CAUTION If a situation arises wherein 91 octane non ethanol or 91 octane with maximum 10% ethanol gasoline is not available, 87 octane gasoline can be substituted in an emergency; however, the prolonged usage of 87 octane gasoline can cause severe engine damage. Gasolines containing more than 10% ethanol are not acceptable gasoline for use in this snowmobile. Do not use gasolines containing methanol. Recommended Injection Oil The recommended oil to use in the oil-injection system is Arctic Cat C-TEC2 Synthetic 2-Cycle Oil (p/n 6639-520 - 48 oz) This oil is specially formulated to be used and meets all of the lubrication requirements of the Arctic Cat C-TEC2 snowmobile engine. CAUTION Any oil used in place of the recommended oil could cause serious engine damage. Filling Gas Tank Since gasoline expands as its temperature increases, the gas tank must be filled to its rated capacity only. Expansion room must be maintained in the tank particularly if the tank is filled with cold gasoline and then moved to a warm area. Engine Break-In The Arctic Cat engine (when new or rebuilt) requires a short break-in period before the engine is subjected to heavy load conditions. During the break-in period (one tank of fuel), a maximum of 1/2 throttle (with varying throttle positions) is recommended; however, brief full-throttle accelerations and variations in driving speeds contribute to good engine break-in. Premixing fuel and oil during the break in period is not required. With the oil delivery control strategy of the electronic oil pump, the pump will automatically compensate and deliver a richer fuel-to-oil ratio during the engine break-in period. Some may choose to pre-mix the first tank and if this is the case, a pre-mix ratio of 100:1 is acceptable. A pre-mix ratio of 100:1 combined with the richer fuel/ oil delivered from the electronic oil pump during break-in may cause additional smoke at start up and idle. Preoperation Checks 1. Visually check all fluid levels. Add fluids as necessary. 2. Visually check the entire snowmobile for any loose fasteners. Tighten as required. 3. Start and run the engine to operating temperature. 4. Check all switches (tether, dimmer, brakelight, emergency stop) to make sure all function properly; then visually check the headlight, taillight, and brake light for proper illumination. 5. Test the operation of the brakes. The brake lever must feel firm when the lever is compressed. Inspect the brake fluid level. The brake fluid level must be just below the high mark on the brake fluid reservoir. Add Arctic Cat approved brake fluid as necessary. Checking Headlight Aim 1. Position the snowmobile on a level floor so the headlight is approximately 8 m (25 ft) from an aiming surface (wall or similar surface). NOTE: There should be an “average” operating load on the snowmobile when adjusting headlight aim. 20 2. Measure the distance from the floor to midpoint of the headlight. 3. Using the measurement obtained in step 2, make a horizontal mark on the aiming surface. 4. Make a vertical mark which intersects the horizontal mark on the aiming surface directly in front of the headlight. 5. Engage the brake lever lock and start the engine. Move the headlight dimmer switch to the HIGH beam position. DO NOT USE LOW BEAM. 6. Observe the headlight beam aim. Proper aim is when the most intense beam is centered on the vertical mark 5 cm (2 in.) below the horizontal mark on the aiming surface. 0744-068 Rear Suspension Style 129 in. Track @ 20 lb Setup Tension After Break-In Tension 35-41 mm (1 3/8-1 5/8 in.) 38-44 mm (1 1/2-1 3/4 in.) 3. Using Axle Nut Spanner Wrench (p/n 0644-558) from the tool kit, loosen the right-side rear axle nut. 0745-813 7. Adjust the headlight adjustment knobs until correct aim is obtained. Shut the engine off; then disengage the brake lever lock. Track Tension/Track Alignment CAUTION Track tension has been initially adjusted at the factory for “run-up testing”; however, track tension (and track alignment) must be adjusted at the dealership according to the following recommendations. To adjust track tension/track alignment, use the following procedure. 1. Elevate the snowmobile on a shielded safety stand high enough to use a spring scale. ! WARNING The tips of the skis must be positioned against a wall or similar object for safety. 2. At mid-point of the track (on the bottom side), hook a spring scale around a track clip; then pull down on the scale to 9 kg (20 lb). Measure the deflection (distance) between the bottom of the wear strip and the inside surface of the track clip. Compare the measurement with the chart. 0744-067 NOTE: Always loosen the right-side rear axle nut when adjusting track tension/alignment. The leftside rear axle nut is secured with green Loctite #609 and should not be loosened or removed. 4. If the distance between the bottom of the wear strip and the inside surface of the track clip exceeds specifications, tighten the adjusting bolts. If the distance between the bottom of the wear strip and inside surface of the track clip is less than specified, loosen the adjusting bolts. 5. When proper track deflection is attained, loosen the right-side rear axle nut just enough to apply blue Loctite #243 to the axle threads; then tighten the nut to 40-45 ft-lb. CAUTION Make certain the right-side rear axle nut is tightened or component damage will occur. 21 6. Start the engine and accelerate slightly. Use only enough throttle to turn the track several revolutions. Shut engine off. ! WARNING DO NOT stand behind the snowmobile or near the rotating track. NEVER run the track at high speed when the track is suspended. NOTE: Allow the track to coast to a stop. Do not apply the brake because it could produce an inaccurate alignment condition. 7. When the track stops rotating, check the relationship of the rear idler wheels and the inner track drive lugs. If the rear idler wheels are centered between the inner track drive lugs, no adjustment is necessary. 9. Loosen the right-side rear axle nut; then on the side of the track which has the inner track drive lugs closer to the rear idler wheel, rotate the adjusting bolt clockwise 1-1 1/2 turns. 10. Check track alignment and make necessary adjustments until proper alignment is obtained. NOTE: Make sure correct track tension is maintained after adjusting track alignment. 11. Loosen the right-side rear axle nut just enough to apply blue Loctite #243 to the axle threads; then tighten the nut to 40-45 ft-lb. ! WARNING If the axle nut is not tightened, the adjusting bolts could loosen causing the track to ratchet, derail, or lock. Test Ride Test ride the snowmobile 5 to 10 minutes. During and after the test ride, do the following: 1. Burnish the brake pads by driving the snowmobile slowly and compressing the brake lever repeatedly until the pads just start to heat up; then allow them to cool down. This process stabilizes the pad material and extends the life of the pads. 2. Allow the engine to cool; then visually check coolant level. Add coolant as necessary. 0740-118 8. If the idler wheels are not centered between the inner track drive lugs, adjust track alignment. ! WARNING Make sure the ignition switch is in the OFF position and the track is not rotating before checking or adjusting the track alignment. 22 3. Recheck track alignment and tension. 4. Check the engine compartment and underneath the snowmobile for any signs of fluid leaks (gas, coolant). General Information 2. While holding the cable housing, lightly pull on one cable end to remove slack. 3. Measure the amount of exposed cable from the cable housing to the end of the cable. Control Locations 0746-486 Arctic Power Valve (APV) System This RPM and exhaust pipe temperature controlled servomotor (servo) actuation system adjusts the size of the exhaust ports to provide peak performance throughout the RPM range. At low RPM, the exhaust valves are held in the DOWN position by return springs. This gives the engine a “low port” exhaust design calibrated to provide maximum low RPM power. 0735-516 4. Repeat steps 2 and 3 on the other cable; then compare the measurements. NOTE: Measurements must be within a range of 36.5 mm ± 1 mm. NOTE: The measurements must be equal and within the specifications. If the measurements are within specifications, no adjustment is necessary. If they are not within specifications, proceed to step 5. 5. Loosen the jam nut on the cable adjuster to be adjusted; then using the adjusting nuts, lengthen or shorten the housing as needed. 6. While holding the adjusting nut in place, tighten the jam nut securely. 7. Install the actuating cables to the servo. 739-152A At high RPM, the exhaust valves are raised. This creates a “high port” exhaust design calibrated to provide maximum performance at high RPM. CAUTION If excessive adjustment is required to attain synchronization, the entire adjustment procedure should be repeated. Exhaust Controlled Timing (ECT) System This system automatically adjusts the ignition timing to provide maximum performance through a variety of operating conditions. The ECM unit receives input on engine RPM (demand) and exhaust pipe temperature (engine condition) and adjusts the ignition timing accordingly. This system is not adjustable and is maintenance free. 739-152B To adjust the APV system, use the following procedure: If a system fault is suspected, disconnect the exhaust pipe temperature sensor; then use an ohmmeter to check continuity of the exhaust pipe temperature sensor located in the expansion chamber. A reading of either 0 ohm or infinity indicates a failed sensor. 1. Remove the actuating cables from the servo. 23 NOTE: A disabled ECT system WILL NOT cause engine damage; however, a failed ECT system will have slower throttle response and may produce slightly less top-end performance. NOTE: Do not adjust the handlebar to a position that allows the brake fluid to be below the low mark on either side of the master cylinder. ! WARNING Testing Exhaust Temperature Sensor 1. Disconnect the sensor harness; then remove the sensor from the exhaust pipe. 2. Suspend the sensor (only up to the threads) in a container filled with automatic transmission oil; then slowly heat the oil on a hot plate. 3. Using a fluid thermometer, closely monitor the oil temperature, and using a digital multimeter with the leads connected to the sensor leads, observe the resistance reading. 4. The resistance must be within the temperature range (see chart). Exhaust Temperature Sensor °F °C ohms 77 25 219.6 122 50 238.5 212 100 275.9 302 150 312.7 5. If the resistance and temperature are not within specifications, replace the sensor. NOTE: Before replacing the sensor, repeat the test to confirm results. Handlebar Tilt The handlebar can be adjusted to the operator’s preference. To adjust the handlebar, use the following procedure: 1. Loosen the eight cap screws securing the handlebar caps to the riser and the riser to the steering post. Tighten cap screws according to specifications to prevent unexpected “fold-down” of the handlebar during operation over rough terrain. DO NOT offset the handlebar so steering capabilities are altered or throttle and brake controls will be affected. Rear Bumper The rear bumper can be removed and replaced. To remove/ install a rear bumper, use the following procedure. 1. On the inside of the tunnel, drill out all rivets and remove both screws and nuts securing the rear bumper to both sides of the tunnel. 2. Remove the existing bumper and install the new one aligning the holes with the holes in the brackets; then rivet the rear bumper to both sides of the tunnel. Secure the front of the bumper using the existing machine screws and nuts. Exhaust System The exhaust system is designed to reduce noise and to improve the total performance of the engine. If any exhaust system component is removed from the engine and the engine is run, severe engine damage will result. Liquid Cooling System The cooling system should be inspected daily for leakage and damage. Also, the coolant level should be checked daily. If leakage or damage is detected and the operator does not feel qualified to service the cooling system, see an authorized Arctic Cat Snowmobile dealer for this service. When filling the cooling system, use a coolant/water mixture which will satisfy the coldest anticipated weather conditions of your area in accordance with the coolant manufacturer’s recommendations. While the cooling system is being filled, air pockets may develop; therefore, fill the bottle and run the engine for five to ten minutes after the initial fill (until the thermostat opens); then add more coolant if necessary. Fill the coolant tank and take the snowmobile for a test ride. Let the engine cool down; then recheck the coolant level and add if necessary. NOTE: Use a good quality, glycol-based, automotive-type antifreeze. CAUTION SNO-2236 2. Adjust the handlebar up or down to operator’s desired tilt, tighten the cap screws evenly to 15 ftlb, and check steering for maximum right/left turning capabilities. 24 After operating the snowmobile for the initial 5-10 minutes, stop the engine, allow the engine to cool down, and check the coolant level. Add coolant as necessary. Drive Clutch And Driven Clutch Shock Absorbers The drive clutch and driven clutch do not require lubrication; therefore, no special maintenance is required by the snowmobile owner. However, the drive clutch and driven clutch should be disassembled, cleaned, and inspected before each race. Each shock absorber should be visibly checked daily for excessive fluid leakage, cracks or breaks in the lower case, a bent plunger, and wear or leakage in the hoses. If any one of these conditions is detected, replacement is necessary. If the operator does not feel qualified to service or replace shock absorbers, see an authorized Arctic Cat Snowmobile dealer for this service. NOTE: A small amount of grease should be applied to the driven shaft before installing the driven clutch. When operating the snowmobile at high altitudes, it may be necessary to change certain component parts of the drive clutch. If the operator does not feel qualified to change clutch components, see an authorized Arctic Cat Snowmobile dealer for this service. CAUTION Use Clutch Puller (p/n 0744-062). Never substitute a different puller or drive clutch damage will occur. Drive Clutch/Driven Clutch Alignment The parallelism and the offset between the drive clutch and driven clutch are set at the factory. Normally, no adjustment is necessary as long as neither the drive clutch nor the driven clutch is removed or disassembled. However, if premature drive belt wear is experienced or if the drive belt turns over, the drive clutch/ driven clutch alignment must be checked. If the operator does not feel qualified to align the clutch/clutch, see an authorized Arctic Cat Snowmobile dealer for this service. Track Studs NOTE: The track on this snowmobile is not equipped with studs. For additional information, see the 2015 POGA Reference Guide. The decision to install studs should be made only after reviewing the International Snowmobile Racing, Inc. regulations as they pertain to the type of racing you participate in. Arctic Cat has a variety of studding products available from your authorized Arctic Cat Snowmobile dealer. Towing If this snowmobile is to be towed by another snowmobile, do not tow using the loops in the skis. The tow rope should be attached to the lower A-arms. 25 Operating Instructions Starting And Stopping Engine It is imperative that the hydraulic brake system be checked for wear and proper operation and that all safety checks found in the accompanying Snowmobile Safety Handbook be performed before attempting to start the engine. After the engine has been started, check the headlights (high and low beam), taillight, and brakelight to be sure they are working properly and adjusted correctly. Make sure all lights are clean to provide maximum illumination. The headlight and taillight must be clean and must be illuminated whenever the engine is running. 1. Test the operation of the hydraulic brake system by compressing the brake lever. The brake lever must feel firm when compressed; then while holding the brake lever in the compressed position, measure the distance between the brake lever and the handlebar. The distance must be greater than 2.54 cm (1 in.). ! WARNING Do not start the engine if the brake system is not functioning properly (if the lever feels spongy, if the brake lever can be compressed to within 2.54 cm (1 in.) of the handlebar, or if the brake fluid level is not correct). Service the brake system or have it properly repaired prior to operating the snowmobile. Serious personal injury or even death may occur if the brake system is not operating properly. 3. Test the throttle control lever by completely compressing and releasing it several times. The lever MUST return to the idle position quickly and completely. CAUTION Always check the coolant level before starting the engine. 4. Move the emergency stop switch to the RUN position. 5. Assure that the tether switch cap is secured to the tether switch. 7. Pull the recoil handle slowly until resistance is felt; then give a short quick pull. Repeat until the engine starts. CAUTION To avoid damaging the recoil starter, DO NOT pull the recoil rope to its limit or release the recoil handle from an extended position. Allow the rope to rewind slowly. CAUTION 0745-816 2. Check the brake fluid level in the master cylinder reservoir. The brake fluid level must be just below the high mark on the master cylinder reservoir. Add Arctic Cat approved brake fluid as necessary. It is extremely important that the engine is properly warmed up before subjecting the engine to high speed operation or heavy loads. Do not idle the engine for excessively long periods of time. The engine should be allowed to idle at least 1-2 minutes before it is operated at more than 1/2 throttle. In extremely cold conditions, the warm-up time will be longer. Cold seizure and piston scuffing caused by insufficient warm-up will not be covered by warranty. Also, do not idle the engine for excessively long periods of time. 8. To shut off the engine, either depress the emergency stop switch to the OFF position or pull the tether switch cap off the tether switch. Braking Operating a snowmobile with hydraulic brakes is different from operating a snowmobile with mechanical brakes. The following items are items that the operator must be familiar with when operating this snowmobile and its hydraulic brake system. SNO-253 26 NOTE: Important additional information on the proper maintenance of the brake system is found in the maintenance section of this manual. 1. Use the brakes wisely. Each time the brakes are applied in all hydraulic brake systems (including automotive applications), heat is transferred to the brake fluid. The amount of heat transferred during high speed stops and/or repetitive use may be high enough to boil the brake fluid and cause the brakes to either fade or may cause an unexpected loss of brakes. If this occurs, the brake fluid requires a cool down period before the brakes will again function properly. This cool down period will vary depending upon the ambient air temperature and the temperature of the brake fluid. If loss of brakes has occurred because of high fluid temperatures, do not operate the snowmobile until the cool down period has expired and brake lever firmness has returned. ! WARNING Excessive repetitive use of the hydraulic brake for high speed stops will cause overheating of the brake fluid and premature brake pad wear which will result in an unexpected loss of brakes. 2. Be sure to maintain the brake fluid at the proper level and take care not to get any moisture in the system as moisture in the brake fluid lowers the boiling point. If the brake fluid is ever boiled (by high speed stops or repetitive use) or if moisture is allowed to enter the system, it must be changed. Never substitute or mix different types or grades of brake fluid. ! WARNING Use only Arctic Cat approved brake fluid. Never substitute or mix different types or grades of brake fluid. Brake loss can result. Check brake fluid level and pad wear before each use. Brake loss can result in severe injury or even death. 3. Never ride the brake. Even maintaining minimal pressure on the brake lever will cause the brake pads to drag on the disc and may overheat the brake fluid. 4. The brake lever lock is not a parking brake and should not be applied for periods exceeding 5 minutes. NEVER OPERATE THE SNOWMOBILE WITH THE BRAKE LEVER LOCK ENGAGED. ! WARNING The brake lever lock is not a parking brake and should not be applied for periods exceeding 5 minutes. The brake lever lock maintains the brake lever in the compressed position and maintains pressure against the brake disc; however, after a period of time, the pressure applied to the brake disc may relax below the amount required to hold the snowmobile stationary. 5. Pumping the brake lever is permissible but not acceptable on a snowmobile designed for racing; therefore, if pumping the brake lever more than twice is necessary to obtain the necessary stopping power, the system must be serviced. If the operator does not feel qualified to service the brake system, see an authorized Arctic Cat Snowmobile dealer for this service. 6. When new brake pads are installed, a “burnishing” process is required. Drive the snowmobile slowly and compress the brake lever several times until the pads just start to heat up; then allow them to thoroughly cool down. This process stabilizes the pad material and extends the life of the pads. Emergency Stopping There are several methods of stopping or slowing the snowmobile under a variety of situations. Identified in the following chart are the ways a snowmobile may be brought to a stop and the effectiveness under normal conditions. ITEM FUNCTION CONDITION Emergency Stop Switch interrupts ignition circuit ALL Tether Switch interrupts ignition circuit ALL slows the driveshaft ALL Brake ! WARNING If any malfunction of the throttle system occurs (such as freezing in fluffy snow) and the engine does not idle down, use the emergency stop switch or disconnect the tether switch IMMEDIATELY to stop the engine. DO NOT start the engine until the malfunction in the throttle system has been located and corrected. ! WARNING If the throttle control lever does not work properly, DO NOT ATTEMPT TO START THE ENGINE. 27 NOTE: If excessive oil deposits are observed, the chain case must be serviced. Also, when the oil level is at the add mark, approximately 2 fl oz of transmission lube must be added to the chain case. Lubrication Chain Case The recommended amount of synthetic chain lube in the chain case is 15 fl oz. Adding more transmission lube to the chain case (above the recommended amount) may result in leakage. To check the transmission lube level, use the following procedure: NOTE: The snowmobile must be on a level surface for this procedure. Check chain case lube level using the chain case sight glass at the right-side footrest. If the lube is at least halfway up the sight glass, the level is correct. CAUTION The correct lubricant to use in the chain case is Arctic Cat Synthetic Chain Lube (p/n 5639-038). Any substitute may cause premature chain failure or serious damage to the chain drive system. Rear Suspension 1. With the gas tank nearly empty (less than 1/4 full), lay the snowmobile on its side. A piece of cardboard should be used to protect the finish on the hood and belly pan. NOTE: Prior to tipping the snowmobile on its side, apply the brake and set the brake lever lock. 2. Lubricate the grease fittings with an all-temperature grease. 0746-115 3. If the lubricant level is above the add mark, the lubricant level is satisfactory. If the lubricant level is below the add mark, proceed to step 4. 4. If oil is low, add transmission lube by removing the oil fill plug. 0746-474 0746-475 0746-471 28 Maintenance The longevity and safety of the snowmobile can be increased by making periodic checks of the items in the following checklist. Perform maintenance checks more often if the snowmobile is used under severe conditions.

CAUTION ! WARNING DO NOT operate the snowmobile when the brake lever lock is engaged or when any component in the brake system is damaged, worn, or adjusted improperly. If the snowmobile is operated and the brake system is not functioning properly, severe personal injury could result. Brake Fluid Checking/Adding 1. With the brake fluid reservoir in a level position and the cover removed, check the fluid level. The brake fluid level must be at the high brake fluid mark in the reservoir. Always press against the tension-collar of the drive sprockets or damage to the components will occur. 51 SNO-253 0745-816 2. If the brake fluid level is below the low mark, remove the reservoir cover and add Arctic Cat approved brake fluid until the fluid level is just below the high mark. Install and secure the reservoir cover. Do not allow moisture to contaminate the brake system. 5. If the distance is less than specified, check the brake fluid level (see Checking Brake Fluid in this sub-section), inspect for leakage, and check the brake pads. CAUTION Brake fluid is highly corrosive. Do not spill brake fluid on any surface of the snowmobile. ! WARNING Do not overfill the reservoir. Overfilling the reservoir may cause the brake system to hydraulically lock. Use only Arctic Cat approved brake fluid. Never substitute or mix different types or grades of brake fluid. Brake loss can result. Brake loss can result in severe injury or even death. Changing The brake fluid must be changed on a regular basis and whenever the brake fluid has been overheated or contaminated. The brake fluid should be changed every 1000 miles or at the end of the snowmobiling season, whichever occurs first. Checking Brake Lever Travel 1. Test the operation of the hydraulic brake system by compressing the brake lever. ! WARNING Do not operate the snowmobile if the distance between the compressed brake lever and handlebar is less than 2.54 cm (1 in.). Brake loss may occur. Brake loss can result in severe personal injury. Bleeding Brake System If the brake lever feels spongy when applied, the brake system may need to be bled. To bleed the brake, use the following procedure: 1. Remove the reservoir cover and fill the reservoir to the high mark with Arctic Cat approved brake fluid. CAUTION Brake fluid is highly corrosive. Do not spill brake fluid on any surface of the snowmobile. ! WARNING Use only Arctic Cat approved brake fluid. Any substitute may result in a loss of brakes. 2. Slide a piece of flexible tubing over the ball of the bleeder valve and direct the other end into a container. 2. The brake lever must feel firm when compressed. 3. To verify lever travel, compress and hold the brake lever to its maximum resistance. NOTE: Do not pump the brake lever as it will produce an inaccurate reading. 4. Measure the distance between the brake lever and the handlebar. The distance must be greater than 1 in. RA032B 3. Slowly compress the brake lever and hold. Open the bleeder valve to release the fluid and air. When the fluid stops, close the bleeder valve; then release the brake lever. 52 4. Repeat step 3 until the brake fluid flows free of air bubbles. 4. Using a pair of pliers, pull one brake pad out of the caliper assembly. NOTE: It may be necessary to refill the reservoir during the bleeding process. NOTE: Changing one pad at a time will prevent one piston from pushing out the other piston from the caliper. 5. When the brake fluid is free of all air and the brake lever feels firm when compressed, fill the reservoir to a level just below the high mark; then install and secure the cover. Remove the tube from the bleeder valve. Checking/Changing Brake Pads The condition of the brake pads must be checked daily and changed if worn or damaged. To check and change the brake pads, use the following procedure. 1. Measure the width of both brake pads. The brake pad width must be greater than 3.2 mm (0.125 in.). If the brake pad width is less than specified, replacement of both pads is necessary. Follow steps 2-6 to replace brake pads. 2. Remove the pin securing the brake pads to the caliper assembly. 3. Remove the brake fluid reservoir cover; then remove most of the brake fluid from the reservoir. Replace the cover. NOTE: The above procedure will allow room for the fluid from the caliper when the pistons are pushed into the caliper for installing new brake pads. Replacing the cover will prevent fluid spillage. 5. Using a flat-blade tool, slowly and carefully push the piston into the caliper. NOTE: The brake pads are labeled (Inner and Outer) for installation purposes. 6. Position the new brake pad into the caliper. 7. Repeat steps 4-6 for the other pad; then secure the pads with the pin. 8. Remove the reservoir cover and remove the remaining fluid; then fill the reservoir with fresh fluid. 9. Pump the brake lever to ensure correct positioning of the brake pads; then release. 10. Fill the reservoir to the proper level with fresh brake fluid. NOTE: When new brake pads are installed, a “burnishing” process is required. Drive the snowmobile slowly and compress the brake lever several times until the pads just start to warm up; then allow them to cool down. This procedure stabilizes the pad material and extends the life of the pads. 53 Drive Train/Track/Brake Systems This section has been organized into sub-sections for servicing drive train, track, and brake systems; however, some components may vary from model to model. The technician should use discretion and sound judgment when removing and installing components. NOTE: Whenever a part is worn excessively, cracked, or damaged in any way, replacement is necessary. SPECIAL TOOLS A number of special tools must be available to the technician when servicing the drive train, track, and brake systems. Description Drive Clutch Bolt Tool Bearing Removal and Installation Tool Movable Sheave Bearing Tool Clutch Alignment Bar Drive Clutch Puller Drive Clutch Spanner Wrench Driven Clutch Compressor Tool Rear Suspension Spring Tool Brake Caliper Bearing Puller p/n 0644-281 0644-167 0644-594 0644-428 0744-062 0644-136 0644-444 0144-311 0744-067 NOTE: Special tools are available from the Arctic Cat Service Parts Department. CAUTION Never attempt to substitute any other drive clutch puller for the recommended puller or severe clutch damage will occur. Drive Belt The drive belt transfers power from the drive clutch to the driven clutch. If the belt is worn, cracked, or stretched, maximum power will not be transmitted and the belt could also fail and therefore must be replaced. Periodic checks (at least once a week under normal usage) of two drive belt specifications are essential. 1. Measure the outside circumference of the drive belt. The belt should be within specifications in circumference. NOTE: Drive belts should be purchased from an. authorized Arctic Cat Snowmobile dealer, as Arctic Cat drive belts are made to exact specifications and of quality material. Belts made by other manufacturers may not be of the same specifications or quality and, therefore, usage could result in poor performance and premature belt failure. CAUTION Never run the engine with the drive belt removed. Excessive revving of the engine could result in serious engine damage and drive clutch failure. Before starting the snowmobile in extremely cold temperatures, the drive belt should be removed and warmed up to room temperature. Once the drive belt is at room temperature, install the drive belt. Also, drive belts have a break-in period of approximately 10 minutes. After installing a new drive belt, drive the snowmobile for 10 minutes at 1/2 throttle or less. This will allow the drive belt to gain its optimum flexibility and will extend drive belt life. Breaking-In Drive belts require a break-in period of approximately 25 miles. Drive the snowmobile for 25 miles at 3/4 throttle or less. By revving the engine up and down (but not exceeding 60 mph), the exposed cord on the side of a new belt will be worn down. This will allow the drive belt to gain its optimum flexibility and will extend drive belt life. Removing 1. Remove the tether switch cap and wait for all moving parts to stop. 2. Set the brake lever lock. 3. Remove the left-side access panel. 4. Using Drive Belt Deflection Tool (p/n 0644-424), thread the tool clockwise into the driven clutch until the movable sheave opens far enough to remove the drive belt. 2.

While holding the negative spring and spacer at the top of the shaft with one hand, insert the shaft and bearing assembly into the shock lower taking care not to spill oil into the air sleeve. Very slowly push the shaft down into the oil while rotating and “wiggling” the shaft until there are no bubbles rising in the oil. 11. Gently lower the negative spring and spacer into the oil taking care not to let the oil overflow into the air sleeve. CAUTION Make sure the piston assembly and the rebound hole in the shaft DO NOT come out of the oil bath. If the rebound adjust hole in the shaft comes out of the oil bath, air can transfer to the underside of the piston aerating the shock. Add oil to the shock as required to keep the hole covered. Pull the shaft assembly out of the oil until the top of the negative spring is even with the end of the body. 12. Carefully lower the bearing assembly into the damping body and thread into the shock; then using an appropriate bearing head tool, tighten the bearing assembly to 50 ft-lb. YYY 10.

Rear Suspension The Sno Pro 600 is equipped with a compression adjustable remote reservoir shock in the rear suspension system. This system utilizes front arm limiter straps. The suspension should be adjusted for the operational needs and riding preference of the operator. The rear springs influence the load carrying capability of the snowmobile and should be adjusted for the weight and riding preference of the operator. Rear Arm Shock Rebound The rear arm shock can be adjusted for rebound qualities. To adjust, use the following procedure. 1. Turn the adjuster clockwise until it stops (hard position). 2. Turn the adjuster counterclockwise to the initial setting (see appropriate Valve Stacks/Specifications page in this manual) or turn the adjuster counterclockwise the desired number of “clicks.” NOTE: On the rear arm shock, the rebound adjuster has a total range of 18 “clicks” or 4 1/2 full turns (4 “clicks”= 1 turn). LLLL 20. Using a high-pressure hand air pump, pressurize the shocks to 200 psi EVOL and 80 psi Main. 77 Front/Rear Arm Shock Compression 1. Turn the adjuster clockwise until it stops (hard position). 2. Turn the adjuster counterclockwise to the initial setting (see page 9 in this manual) or turn the adjuster counterclockwise the desired number of “clicks.” NOTE: On the rear arm shock, the compression adjuster has a total range of 18 “clicks” or 3 full turns (6 “clicks” = 1 turn). Front Arm Shock Spring The skid frame front arm shock spring is adjustable. However, Arctic Cat recommends that the shock spring be adjusted to a maximum of 6.4 mm (1/4 in.) up or down from the standard pre-load setting. NOTE: The standard pre-load spring length (installed) is 7.64 in. CAUTION Do not exceed the maximum 6.4 mm (1/4 in.) up or down from the standard pre-load setting. When customizing the amount of ski pressure, be sure to not over-adjust the front arm shock spring to adversely affect steering and operator control of the snowmobile. Some experimentation may be required until the proper adjustment for the operator’s individual style is obtained. ! WARNING Do not adjust the front arm shock to a point at which steering and operator control of the snowmobile are adversely affected. NOTE: Each driver’s style is different and some experimentation will be required to become familiar with the above adjustment procedure. ! WARNING DO NOT make adjustments while operating the snowmobile. Keep both hands on the handlebar while the snowmobile is moving. Adjusting Rear Spring Tension Rear spring tension adjustment is accomplished by rotating the adjusting cams. Position 3 provides the stiffest ride, and position 1 provides the softest ride. Always rotate the cam from the lighter position to the heavier position. Servicing Zero-X Shock Absorbers This procedure shows the proper method for servicing the front arm shock absorber w/“piggy-back” reservoir. ! WARNING Before starting, read through all of these instructions first to become familiar with the procedure. Make sure the work area is clean and all of the necessary tools are available.

If the glass is touched, it must be cleaned with a dry cloth before installing. 1. Disconnect the headlight harness connector from the bulb; then remove the rubber grommet from the headlight housing. Ski Wear Bar The ski wear bar is a replaceable bar attached to the underside of the ski. The purpose of the wear bar is to assist in turning the snowmobile, to minimize ski wear, and to maintain good steering control. If the snowmobile is operated primarily in deep snow, ski wear bar wear will be minimal; however, if the snowmobile is operated on terrain where the snow cover is minimal, the ski wear bar will wear faster. To maintain positive steering characteristics, Arctic Cat recommends that the ski wear bars be checked before each use and replaced if worn beyond 1/2 of the original diameter. Ski wear bars are available from an authorized Arctic Cat Snowmobile dealer. 2. Rotate the bulb retainer counterclockwise until it unlocks from the housing; then remove the bulb. ! WARNING Operating the snowmobile with excessively worn or missing wear bars may result in a loss of steering control. NOTE: Always check the official rules for the appropriate wear bars for the event being participated in. Removing 1. Raise the front of the snowmobile and place it on a support stand. 0746-096 86 2. Remove the lock nuts (and washers on the Sno Cross model) securing the wear bar to the ski. Rail Wear Strip Arctic Cat recommends that the wear strips be checked weekly and replaced as necessary. Measure the wear strips at 25.4 cm (10 in.) intervals. Wear strips must be 10.7 mm (0.42 in.) thick or thicker. If wear strip measurements are less than specified, replacement of both wear strips is necessary to prevent premature track clip wear and possible track damage. NOTE: The rail wear strips will wear rapidly if the snowmobile is operated on terrain on which the snow cover is minimal. Loose snow is required to cool and lubricate the wear strips and prevent accelerated wear. 0743-185 3. Remove the wear bar from the ski. Installing 1. Move the wear bar into position on the bottom of the ski. 2. Align the wear bar studs with the holes in the ski; then install the lock nuts with washers (Sno Cross model only). Tighten to 15 ft-lb. 0744-875 87 Performance Tips Operating a high performance snowmobile requires a special attention. Often, a minor adjustment will result in a large increase in performance. This section is intended to highlight minor conditions that adversely affect performance and the adjustments needed to correct them. Be sure, however, to thoroughly read and understand this entire manual especially the section on spark plugs, track tension and alignment, and suspension. DRIVE BELT — This link between the engine and drive train is often the most neglected component. The drive belt must have the proper fit in the drive clutch and driven clutch. Proper fit is when the top surface of the drive belt is flush with the top or up to 1/16 in. higher than the driven clutch sheaves (with the sheaves fully closed). If the belt sits below this level, the snowmobile will bog at slow speeds and will have a slower maximum speed. To correct this condition, first determine if the drive belt is within specifications (see Drive Belt section) and replace if worn or too long. Secondly, always run the drive belt in the same direction. Installing the drive belt so the part number can be read will ensure that the drive belt is always run the same direction. 88 DRIVE CLUTCH AND DRIVEN CLUTCH — Keeping the drive clutch and driven clutch clean should be the primary consideration of the operator. The clutch sheaves can be cleaned of any drive belt accumulation using a clean cloth and parts-cleaning solvent. All pivot points can be maintained clean using compressed air. CAUTION Use Clutch Puller (p/n 0744-062). Never substitute a different puller or drive clutch damage will occur. CARBURETOR MAIN JETS — Proper carburetion, specifically proper main jets, is absolutely necessary to obtain peak performance. Since ambient temperature and operating altitude both affect the main jet size needed for optimum engine performance, the main jets will often need to be changed whenever the temperature changes 20° F (11° C) or whenever operating altitude varies by more than 1000 feet. Preparation For Storage Prior to storing the snowmobile, it must be properly serviced to prevent corrosion and component deterioration. To prepare the snowmobile for storage, Arctic Cat recommends the following procedure. 1. Clean the seat cushion with a damp cloth and Arctic Cat Vinyl Protectant. 2. Clean the snowmobile thoroughly by hosing dirt, oil, grass, and other foreign matter from the skid frame, tunnel, hood, and belly pan. Allow the snowmobile to dry thoroughly. DO NOT get water into any part of the engine. 8. Drain the chain-case lubricant. Remove the chaincase cover and inspect chain, sprockets, and chain tensioner for wear and the chain for proper tension. Install the chain-case cover and seal; then pour Arctic Cat Synthetic Chain Lube (p/n 5639038) into the oil level stick filler hole according to specifications. 9. Remove the drive belt from the drive clutch/driven clutch. Lay the belt on a flat surface or slide it into a cardboard sleeve to prevent warping or distortion during storage. 10. Clean and inspect the drive clutch and driven clutch. 11. Apply light oil to the upper steering post bushing and shafts of the shock absorbers. 3. Place the rear of the snowmobile up on a shielded safety stand. Remove the air-intake silencer boots from the carburetors. 12. Lubricate the rear suspension and bellcranks with a all-temperature grease. 4. Start the engine and allow to idle. With the engine idling, spray an Engine Storage Preserver into the carburetors until the engine exhaust starts to smoke heavily or until the engine starts to drop in RPM. Turn engine off. 13. Tighten all nuts, bolts, and cap screws making sure all calibrated nuts, bolts, and cap screws are tightened to specifications. Make sure all rivets holding the components together are tight. Replace all loose rivets. 5. Plug the exhaust system outlet with a clean cloth. 14. Clean and polish the hood, console, and chassis with Cat Cleaner (p/n 4639-371). DO NOT USE SOLVENTS. THE PROPELLANT WILL DAMAGE THE FINISH. 6. With the tether switch cap removed: A. Disconnect the high tension leads from the spark plugs; then remove the plugs, connect them to the leads, and ground them on the cylinder heads. CAUTION Never crank the engine over without grounding the spark plugs. Damage to coils and/or CDI unit may result. B. Pour 29.5 ml (1 fl oz) of SAE #30 petroleumbased oil into each spark plug hole and pull the recoil starter handle slowly about 10 times. C. Install the spark plugs and connect the high tension leads. 7. Drain the gas from the carburetor float bowls. Fill the gas tank to its rated capacity; then add Arctic Cat Fuel Stabilizer (p/n 0436-907) to the gas tank following directions on the container for the stabilizer/gasoline ratio. Tighten the gas tank cap securely. 15. If possible, store the snowmobile indoors. Raise the track off the floor by blocking up the back end making sure the snowmobile is secure. Loosen the track adjusting bolts to reduce track tension. Cover the snowmobile with a machine cover or a heavy tarpaulin to protect it from dirt and dust. 16. If the snowmobile must be stored outdoors, position the snowmobile out of direct sunlight; then block the entire snowmobile off the ground making sure the snowmobile is secure. Loosen the track adjusting bolts to reduce track tension. Cover with a machine cover or a heavy tarpaulin to protect it from dirt, dust, and rain. CAUTION Avoid storing in direct sunlight and using a plastic cover as moisture may collect on the snowmobile causing corrosion. 89 Preparation After Storage Taking the snowmobile out of storage and correctly preparing it for another season will assure many miles and hours of trouble-free snowmobiling. Arctic Cat recommends the following procedure. CAUTION If the gas in the carburetor float chambers was not drained prior to storage, the carburetors must be cleaned before starting the engine. 1. Clean the snowmobile thoroughly. Polish the exterior of the snowmobile. 2. Clean the engine. Remove the cloth from the exhaust system. Check exhaust system and airintake silencer for obstructions. 3. Inspect all control wires and cables for signs of wear or fraying. Replace if necessary. Use cable ties or tape to route wires and cables away from hot or rotating parts. 4. Inspect the drive belt for cracks and tears. Check belt specifications. Replace if damaged or worn. Install the drive belt. NOTE: If the old belt is worn but in reasonable condition, keep it in the tool box as a spare in case of emergency. 90 5. Inspect the in-line fuel filter and replace if necessary. Inspect all fuel hoses for deterioration or cracks; replace if necessary. Make sure all connections are tight. 6. Inspect the entire brake system (fluid level, pads, etc.), all controls, headlight, taillight, brakelight, ski alignment, ski wear bars, and headlight aim; adjust or replace as necessary. 7. Inspect the spark plugs. Replace, gap, or clean as necessary. 8. Adjust the track to the proper tension and alignment. NOTE: Prior to tipping the snowmobile on its side, apply the brake and set the brake lever lock. 9. Check air pressure in the front ski shocks. 10. Adjust the carburetors, throttle cable, and choke cable. ! WARNING Be sure to tighten the swivel adapter jam nuts securely. If a jam nut isn’t tightened, the adjuster can rotate out of the carburetor cap causing the throttle slide not to return to the full-closed position. 11. Tighten all nuts, bolts, and cap screws making sure all calibrated nuts, bolts, and cap screws are tightened to specifications. 12. If not done during preparation for storage, lubricate the front and rear suspension and spindles with an all-temperature grease.
