using Automatic Transmission Fluid,
Type "A". Track bearings are sealed
type and do not require lubrication.
On models with reversing transmission, the transmission pedestal (Fig.
1) should be filled to level of fill plug
with Automatic Transmission Fluid,
Type "A". Reservoir capacity is 70 cc
(approx. 2% fluid ounces). Fluid level
should be checked every 25 hours or
oftener if leakage is evident,
LUBRICATION
The engine is lubricated by oil
mixed with the fuel. Correct fuel-oil
ratio is 16:1 for 1965 and 1966 models
or 24:1 for later OMC engnes. On JLO
and Kohler engines, use 20:1 mixture.
The primary drive sheave on OMC
clutch contains a grease fitting which
is accessible through a port in transmission guard alongside the "NEUTRAL SHIFT" knob. Turn crankshaft
slowly until fitting is aligned with
port, and pump in two or three shots
of low temperature grease such as
Texaco ALL-TEMP, each 15-20 hours
of operation. CAUTION: Do not overlubricate, or belt damage and malfunction could result.
Lubricate steering linkage with
light engine oil every 25 hours and
ski columns (spindles) annually with
Texaco ALL-TEMP or equivalent.
The drive chain on models with
open chain is automatically oiled by a
tube leading from crankcase bleeder
valve. Be sure that tube is open and

with enclosed chain case, maintain lubricant at level of lowest cover screw
STEERING SKIS. Steering skis
should be parallel with each other
and with vehicle frame when handle
bar is in normal straight driving position. To adjust the steering gear, first
remove engine shroud (vehicle hood),
then disconnect steering tie rod at
either end.
DRIVE CHAIN. Roller drive chain
should have y4-% inch deflection
when measured midway between
sprockets. To check the adjustment
on open drive chain, it is necessary
VEHICLES
OMC
On late models, brake body is
housed in a pressed steel bracket as
shown in Fig. 5. To adjust Jthe brake,
remove cotter pin and turn nut (N)
until there is a slight drag on brake
disc (10); then back off nut to the
first castellation and insert cotter pin.
On all models, check to see that
parking latch can be engaged before
releasing vehicle for service. Travel
of hand lever can be adjusted by
loosening jam nut (1) and turning
cable housing anchor screw (2); or by
loosening clamp screw (3) and repositioning brake cable on actuating
arm.

to remove left foot rest and chain
guard. Adjustment for models prior to
1968 is by means of eccentric bearing
housing for shaft which carries upper
chain sprocket and driven pulley; refer to Fig. 2. To make the adjustment,
loosen locknut (7) and move eccentric
screw (8) down to tighten chain or
up to loosen chain.
On 1968 and later models with open
chain an idler sprocket is used and
tension is adjusted by sliding the idler
bracket in slotted holes.
On 1969 Challenger and Bobcat^
chain is tightened by loosening the
three nuts (N—^Fig. 3) and by shifting
intermediate shaft in slotted holes.
Adjustment is determined by checking backlash of secondary sheave(s).
On most models with enclosed chain
case, the idler sprocket mounts on an
eccentric housing which clamps to
outside of chain case (See Fig. 4). To
adjust the chain, loosen the clamps
and remove upper chaincase cover as
shown. Turn main drive sheave forward (clockwise) to eliminate slack
in back flight of chain, then turn eccentric housing counter-clockwise until chain adjustment is correct. Tighten
clamps and reinstall top cover.
g, 3—View of intermediate shaft showing
secondary sheave (S) and nuts ( N l which
retain housing to chain case.
On some later models, the enclosed
chain case uses an eccentric chain
tightener of the type shown in Fig. 2.
BRAKE. To adjust the caliper type
disc brake on early models with clamp
type adjuster, loosen the locknut and
tighten clamp adjusting screw until it
stops; then back out approximately
%-turn and tighten locknut.

NEUTRAL CONTROL. On 1967 and
earlier models a neutral shift knob
was located on the primary (drive)
sheave hub and was accessible
through belt guard.
On 1968 models a neutral control
knob is located on instrument panel.
Pulling the knob out:
(1) Retards ignition timing.
(2) Locks primary sheave in
neutral.
(3) Opens compression release
valves.
(4) Sets throttle speed.
Any of the adjustments can be made
independently, however if ignition
timing adjustment must be made, the
other adjustments will need to be
changed. Proceed as follows:
Disconnect magneto advance arm
from bell crank actuator arm as
shown in Fig. 6 and push down on
advance arm until it stops. With neutral control knob pushed in and detent engaged, loosen locknut (Fig. 7)
and shorten or lengthen neutral control rod until magneto advance arm
can be reconnected to bell crank actuator arm without moving magneto
away from advance stop. Tighten the

locknut when adjustment is completed.
With neutral control knob remaining at "IN" (Operating) position,
check the clearance between neutral
control knob and button on primary
drive sheave as shown in Fig. 8. Clearance should be ^-inch as shown. If
it is not, adjust at control cable housing nuts, at point where cable housing
attaches to engine frame.
With neutral control knob "IN",
check for ^-inch free play at compression release cables as shown in
Fig. 9. Adjust at cable housing bracket
fittings as shown.
Refer to Fig. 10. Loosen the locknut on "L" shaped throttle rod and
back rod out of ball joint several
turns. Pull out on neutral control
knob until it snaps into neutral detent
position; then turn "L" shaped rod
into ball joint until idle compensator
cam contacts its stop on high speed
needle boss and short hooked en(i of
rod contacts idle control lever.
Tighten locknut when adjustment is
completed.

REVERSING TRANSMISSION
LINKAGE ADJUSTlMniNT. To adjust
the reverse shift linkage on Wide
Track models so equipped, proceed as
follows:
Pull out on reverse shifter lever
and refer to Fig. 13. Actuating clevis
and lock plates should snap over-center as shown and clevis eye should
touch pinion shaft actuating link. If
clevis eye does not touch and linkage does not snap over-center, shorten
linkage at clevis eye. If linkage is
straight and link eye does not touch,
lengthen the linkage. When linkage
is correctly adjusted, shorten or
lengthen operating rod until dash
panel locknut (Fig. 14) JUST
TOUCHES dash with lever moved to
forward position.
TRACK. Tq adjust track tension,
raise rear of vehicle until track is
clear of ground.
On 1967 and earlier models, track
tension is correct when distance (A
^Fig. 15) between top of track and
center truck (bogie) wheels is %inch.
To make the adjustment, loosen the
three clamp bolts (1—^Fig. 16) and
locknut (2) on each side of vehicle,
then turn adjusting screw (3) until
measurement is correct.
On later models with spring loaded
bogie wheels, refer to Fig. 17 and proceed as follows. With track clear of
ground, loosen nuts on clamp bolts
(1) and turn adjusting bolts (2) until distance (A) measures as follows:
Models 1580, J1580

Models 2080, J2080, 2085,

NOTE: When track tension has
been adjusted, alignment MUST be

OVERHAUL
SKIS. In 1965, a two-leaf spring was
used and ski was not equipped with
a detachable runner. Later models use
a three-leaf spring. In 1966, two different skis were used and runners
were not interchangeable; measure
runner length to be sure the correct
part is ordered when renewal is indicated.

ENGINE & DRIVE. Engine and
drive unit is mounted on a separate
frame and can be removed as a unit
after removing engine shroud (hood),
drive chain, and brake and throttle
controls. Refer to Figs. 18 and 19 for exploded views.
The recoil starter ratchet mount is
provided with a holding hole (Arrow—Fig. 20). When removing the
transmission (torque converter) drive
sheave, first remove starter and insert a suitable holding bar through
the hole to keep crankshaft from turning. Turn drive sheave in normal direction of engine rotation to unscrew
the sheave.
REVERSING TRANSMISSION. On
models so equipped, the reversing
transmission serves as the mounting
pedestal for the torque converter secondary (driven) sheave and main
drive chain drive sprocket. Refer to
Fig. 21.
The two upper views (F) show the
transmission engaged in forward gear.
The spring loaded dog clutch (4) connects the input shaft (2) and output
shaft (3). Reverse pinion (6) is pulled
back from both shaft gears, and both
shafts turn together as a unit.
The two lower views (R) show the
transmission engaged in reverse gear.
Action of the shift linkage moves the
reverse pinion (6) into engagement
with the input and output shaft gears.
The wedge-shaped shifter clevis (7)
moves the dog clutch (4) out of engagement with input shaft (2) and
shafts t u r n in opposite directions
through the reversing action of the
gears. The transmission has no neutral position.
