Disassembly
1. Remove the TALAS aircap. To aid removal, hold the TALAS lever with your other hand as you
turn the aircap.
2. While holding a rag over the topcap assembly, depress the main air chamber Schrader valve
to release air pressure.
3. Using a 3/8" socket, remove the TALAS lever locknut. Hold the TALAS lever with your other
hand as you loosen the nut. After the nut is removed, simply lift the TALAS lever off the
topcap assembly.

4. Remove the detent ring. Use needlenose pliers to grab the small dowels on either side of the
Schrader valve, and pull the detent ring straight up. Before removing the detent ring, look at
the notches to find the ball bearing; prepare to catch the ball bearing as you pull the detent
ring up and off.
5. Using a 3/8" socket, remove the TALAS inner tube by turning the socket counterclockwise.
The inner tube assembly is not screwed in. Rather, it is corkscrewed into the topcap
assembly and will rise up and out of as you turn the socket.
Page 4 of 25
6. Remove the red IFP chamber screw with a 2mm hex wrench.
7. Screw in the TALAS IFP Charging Tool into the IFP chamber port. Cover the Schrader valve
with rag and release all air pressure from the IFP chamber.
8. Remove the IFP Tool.
9. Unscrew–but do not remove–the damper topcap with a 26mm 6-point socket. Be careful not
to slip and damage the wrench flats. You may need to grind down the socket so that it
properly grips the wrench flats on the topcap.
Page 5 of 25
10. Leave the topcap assembly on. Secure your fork so that the fluid inside of the fork does not
spill out.
11. Turn the fork upside-down and, using a 10mm socket, remove the spring-side bottom nut.
12. Push down on the protruding spring-side shaft to push up the air shaft plunger. If it can't be
dislodged, screw the bottom nut on to the shaft at least 2 full turns and softly tap the bottom
nut with a soft-faced mallet and remove the bottom nut.

13. Unscrew the TALAS Topcap Assembly from the upper tube.
14. Lift up on the TALAS Topcap Assembly to remove it from the upper tube.
Page 7 of 25
15. Turn the fork upside-down. Push down on the end of the TALAS Lower Shaft that is
protruding from the bottom of the upper tube. Hold your hand under the topcap area so that
the Lower Shaft doesn't fall on the ground as you push it down and out of the upper tube.
Service
1. Unscrew the Upper Check Valve Bolt (P/N: 234-04-082) with an 8mm wrench by holding the
Inner Ferrule Nut (P/N: 234-04-103) with a 5mm wrench.
2. Look inside the Upper Check Valve Bolt to find the O-Ring (P/N: 029-08-043). If it is not
Page 8 of 25
there, check the top of the Inner Ferrule (P/N: 234-04-102).
3. Unscrew the Upper Check Valve Bolt from the Adjuster Screw. Inside the Adjuster Screw find
and examine another O-Ring (P/N: 029-00-003).
4. Replace this O-Ring if the TALAS forks
sinks past normal sag adjustment
statically, although it will be more noticeable at the longest travel setting (i.e., 140mm or
130mm).
The following drawing illustrates the difference between a properly situated O-Ring and one
that is oriented incorrectly:
Page 9 of 25
5. When re-installing, place O-Ring on end of Inner Ferrule instead of inside the Upper Check
Valve Bolt, as shown below. This will ensure that O-Ring is properly centered and oriented
upon re-assembly. Lubricate the Inner Ferrule and O-Ring before re-assembly.
6. Screw the Inner Ferrule Nut to the Upper Check Valve Bolt and torque to 16 in/lb. (181 Ncm).
Page 10 of 25
7. The Adjuster Screw O-Ring (P/N: 029-03-010-A) can be replaced if necessary.
8. If the seals on the IFP need to be replaced, remove the Retaining Ring Rotoclip (P/N: 03800-006) using a clip removal tool. After removing the clip, remove the shim and square ORing and then slide the IFP off the outer tube.
Page 11 of 25
9. The IFP TALAS II Main Seal (P/N: 036-01-009) on the IFP (P/N: 222-01-093) can be replaced
as well as the Inner Seal (P/N: 036-01-012) on the IFP.
10. The TALAS II Topcap Assembly (P/N: 234-04-073) O-Rings (P/N: 029-03-022-A [Top] & 02903-021 [Bottom]) can be replaced if necessary.
11. The TALAS Lower Air Shaft assembly usually does not require any service other than
potential replacement of the U-Cup Seal (P/N: 036-01-018) and Urethane O-Ring (P/N: 02908-024) on top of the Lower Piston Bolt (P/N: 234-04-034). When placing the U-Cup Seal
back on to the Lower Outer Piston, ensure the OD U-Cup lip is oriented towards the top of
the air shaft.
Page 12 of 25
12. To replace the Urethane O-Ring, place the Lower Air Shaft assembly in TALAS shaft clamps.
Use a 13mm open-end wrench to unscrew the Lower Piston Bolt (P/N: 234-04-034). Use a
plastic dental pick to remove the Urethane O-Ring. Removal of the Lower Piston Bolt is
optional, but prevents the O-Ring from falling inside the air shaft. Place the O-Ring into the
Lower Piston Bolt groove then hold it there with the plastic dental pick. As you hold the pick
in place, push the protruding portion of the O-Ring in with your other hand.
Assembly
Page 13 of 25
1. Place 3cc of FLOAT Fluid into the upper tube.
2. Pre-lube with FLOAT Fluid the TALAS Lower Air Shaft seal and push it into the upper tube.
3. Use a 15mm deep socket with extension to push the Air Shaft assembly down until it
protrudes from the bottom of the upper tube.
Page 14 of 25
4. Place 5cc of FLOAT Fluid inside the upper tube.
5. From the bottom, push up on the lower TALAS Lower Shaft assembly a few inches. Place the
TALAS Topcap Assembly into the upper tube carefully; remember, you need to insert the
travel adjust rod into the lower seal head hole. Once it is engaged, you can push down on the
Topcap Assembly. Screw the Topcap on and torque to 165 in/lb. (1864 N-cm) using a torque
wrench.
Page 15 of 25
6. Screw the TALAS IFP Recharge tool (P/N: 803-00-127) into the IFP port and pressurize the
IFP chamber to 150 psi (10.34 bar) using a FOX High Pressure Pump. Screw on the red IFP
chamber socket head screw with a 2mm hex key.
Page 16 of 25
7. Lubricate the O-Ring on the Adjuster Screw assembly and then gently push the assembly into
the center hole of the TALAS ll Topcap Assembly.
8. Using a 3/8" socket, screw the Adjuster Screw in by hand.
Page 17 of 25
9. Using the FOX High Pressure Pump, pressurize the TALAS main air chamber to 75 psi
(5.17bar).
Use care when unscrewing the pump from the adjuster
screw Schrader valve. The adjuster screw may
unintentionally be removed. Hold the adjuster screw nut
with your fingers or a wrench as the pump is unscrewed
from the Schrader valve.
TALAS II Knob Timing Procedure (View and print out 605-04-371: TALAS II KNOB TIMING to assist
with this procedure)
Now that the TALAS main air chamber is charged, use care
when turning the adjuster screw during the knob timing
procedure. Injury can occur if the adjuster screw is turned
too far as it may shoot out due to the pressure inside the
chamber.
If possible, use a TALAS I travel adjuster knob for the
following procedure.
10. You can use TALAS I travel knob (P/N: 234-04-013) or a 3/8" socket to turn the TALAS
Page 18 of 25
Adjuster Assembly. Ensure it is engaged with the 3/8" tank valve nut, then turn the knob
fully clockwise (FULL IN on the TALAS II KNOB TIMING sheet).
11. Turn the TALAS knob out half turn (1/2 TURN OUT), or 180-degrees counterclockwise. (Use
a reference point on the travel knob to assist you.)
Page 19 of 25
12. Compress the TALAS lower shaft so that it settles at the lowest travel setting. Confirm by
measuring.
When hand dyno-ing the fork, do not place your hand on
the travel topcap. This places pressure on the travel topcap
assembly and will adversely affect your travel
measurements.
Page 20 of 25
13. Place an O-Ring on the lower shaft to visually confirm the travel adjustments (jumps) that
will be performed in the next steps.
14. SLOWLY start turning in (TURN IN, or counterclockwise) the TALAS travel knob until the
lower shaft jumps out of the upper tube (JUMP 1). The fork just went from the shortest to
the middle travel setting.
15. SLOWLY continue turning in (TURN IN) the TALAS travel knob until the lower shaft jumps
again (JUMP 2). The fork just went from the middle to the longest travel setting.
The 2007 TALAS 32 RLC/RL/R have 140mm of travel,
and the 2007 TALAS X has130mm of travel.
140, 120 or 100mm of exact travel will not always be
achieved. Please refer to the 32MM Fork User Specifications
to view these tolerances.
Page 21 of 25
16. Now you must turn the TALAS travel knob in 2 degrees (TURN IN 2 degrees). Two degrees
is a very small distance! The diagrams below illustrate how small the adjustment needs to
be.
Each hole on the adjuster screw (as shown below) represents a 10° segment. Therefore, the
adjuster screw needs to be turned 1/5 of the distance between the center of each hole: 2
degrees.
Use a reference point on the edge of the topcap assembly to make this adjustment. It also
helps to use the 3/8" socket and turn it by hand.
Page 22 of 25
17. Once the proper travel settings are achieved, remove the TALAS I travel adjuster knob, or
the 3/8" socket if that was used instead. Place the TALAS Centering Tool (P/N: 399-27-382)
Page 23 of 25
on top of the tank valve.
18. Slide the Detent Ring over the Centering Tool and into the Topcap Assembly. Align the
Detent Ring so that the ball bearing lines up with notch #3 in the Topcap Assembly, as
shown below. For added reference, notch #3 is the last notch going in a clockwise direction.
19. Notice the short dowels on the topside of the Detent Ring (see drawing below); on the
bottom side of the detent ring you will see longer dowels. These longer dowels need to slide
Page 24 of 25
into the holes on top of the adjuster screw.
Grease the spring and ball (on early 07 32mm TALAS ll, a spacer (P/N: 234-04-136) is used)
and place it into the side hole. You can use the flat side of a flat-blade screwdriver to press
the ball into detent hole as you push the Detent Ring down. As you slide the Detent Ring
down the TALAS Centering Tool and onto the Adjuster Screw, you should be able to feel
when the dowels have properly been inserted into the holes on top of the Adjuster Screw.
20. Place the TALAS II Travel Adjust Lever onto the Detent Ring. Orient the knob so that the
lever is at or near the 9 o'clock position (rider's perspective), which is the longest travel
setting.
Page 25 of 25
21. Place the 7/16" lock nut on the valve stem and torque it to 45 in/lb (5.08 N-m) using a
torque wrench.
22. Don't forget to take the O-Ring off the lower shaft.
