4. Check drive clutch/driven pulley alignment (see

Drive Clutch/Driven Pulley in this section); adjust
as necessary.

5. Install the drive belt and check drive belt

deflection (see Drive Clutch/Driven Pulley in this
section). Secure the belt guard.

Drive Clutch/

Driven Pulley

CHECKING OFFSET

If premature drive belt wear is experienced or if the
drive belt turns over, parallelism/offset must be
checked. Also, parallelism/offset must be checked
whenever either the drive clutch or driven pulley is
serviced. To check the parallelism/offset, use the
Clutch Alignment Bar (p/n 0644-003) and the follow-
ing procedure.

1. Open the belt guard and remove the drive belt.

2. Install the clutch alignment bar between the drive

clutch sheaves and against the outside edge of the
driven pulley stationary sheave.

3. Allow the alignment bar to rest on the drive clutch

shaft.

0733-912

„ NOTE: The alignment bar must extend beyond
the front edge of the drive clutch.

4. With the bar against the outside edge of the driven

pulley stationary sheave at points A and B, the bar
should just clear the inside edge of the stationary
sheave of the drive clutch and rest on the
stationary shaft. If the bar does not clear the inside
edge or is more than 1.5 mm (0.060 in.) from the
inside edge, the offset must be corrected.

CORRECTING OFFSET

1. To correct offset, the driven pulley must be moved

laterally on the driven shaft. Remove the cap
screw and washers securing the driven pulley; then
remove the driven pulley.

„ NOTE: If the driven pulley is tight on the driven
shaft, pull the driven pulley off using the Driven
Pulley Puller (p/n 0744-023).

2. To move the driven pulley inward on the shaft,

remove washer(s) as required from behind the
pulley.

3. To move the driven pulley outward on the shaft,

add alignment washer(s) as required behind the
driven pulley.

„ NOTE: Make sure the keyways match when
installing the driven pulley. Arrange washers to
allow the least amount of “float” on the driven
shaft. A maximum of 1.5 mm (0.060 in.) of float is
acceptable.

4. Install the driven pulley and secure with a cap

screw and washers. Tighten the cap screw to 2.6-
3.3 kg-m (19-24 ft-lb).

CHECKING PARALLELISM

1. Check parallelism of the drive clutch/driven pulley

using the alignment bar and reference points X and
Y with the alignment bar against the driven pulley
at points A and B. Using a calipers or a machinist's
scale, measure X and Y from the back side of the
alignment bar. Measurements X and Y must be
equal or measurement Y must be more than
measurement X, but Y must not exceed
measurement X by more than 1.6 mm (0.062 in.).

„ NOTE: The offset must be correct before check-
ing parallelism.

2. If parallelism is not within specifications, the

parallelism must be corrected.

CORRECTING PARALLELISM (Torque 
Bumper w/Bearing Support Bracket)

1. To correct parallelism, minor adjustments can be

made by adjusting the torque bumper on the left-
rear engine mount.

A. Loosen the cap screws and nuts securing the

engine mounting brackets to the front end.

B. Using the jam nuts on the torque bumper, adjust

parallelism and periodically check the parallel-
ism. When the parallelism is correct, tighten the
cap screws and nuts securing the engine mount-
ing brackets to the front end; then tighten the
torque bumper jam nuts allowing 1.5 mm
(0.060 in.) clearance between the torque
bumper and the engine.

2. Recheck both offset and parallelism to ensure

accuracy and make further adjustments as
necessary.

„ NOTE: After parallelism and offset have been
corrected, check for proper drive belt deflection.
This is critical for optimum performance.

CORRECTING PARALLELISM (Torque 
Bumper w/Shims)

1. To correct parallelism, minor adjustments can be

made by removing shims from or installing shims
on the left-rear engine mount.

A. Loosen the cap screws securing the engine

mounting brackets to the front end.

B. Add or remove shims as needed to attain cor-

rect parallelism.

C. When parallelism is correct, secure the engine

mounting brackets to the front end.

2. Recheck both offset and parallelism to ensure

accuracy and make further adjustments as
necessary.

„ NOTE: After parallelism and offset have been
corrected, check for proper drive belt deflection.
This is critical for optimum performance.

CORRECTING PARALLELISM (Engine 
Snubber w/Engine Plate)

1. To correct parallelism, minor adjustments can be

made by adjusting the engine snubber on the left-
rear engine mount.

A. Loosen the cap screws securing the engine

plate to the engine mounts.

B. Either lengthen or shorten the snubber and peri-

odically check the parallelism measurement.
When the parallelism measurement is correct,
loosen the snubber to allow 1.5 mm (0.060 in.)
clearance between the snubber and the engine;
then lock the jam nuts on the snubber and
tighten the cap screws securing the engine
plate.

2. Recheck both offset and parallelism to ensure

accuracy and make further adjustments as
necessary.

„ NOTE: After parallelism and offset have been
corrected, check for proper drive belt deflection.
This is critical for optimum performance.

DRIVE BELT DEFLECTION

Drive belt length, condition, and deflection are all
important for peak performance. To check and adjust
drive belt deflection, use the following procedure.

1. Turn the engine off; then open the belt guard.

2. Make sure the drive belt is sitting at the top of the

driven pulley sheaves.

3. Place a straightedge on top of the drive belt. The

straightedge should reach from the drive clutch to
the top of the driven pulley.

4. Using a stiff ruler centered between the drive

clutch and driven pulley, push down on the drive
belt just enough to remove all slack. Note the
amount of deflection on the ruler at the bottom of
the straightedge. The deflection should be within
the range of 25-31 mm (1-1 1/4 in.).

„ NOTE: Push down on the belt with the ruler only
until the bottom of the belt flexes upward; then
read the amount of deflection.

5. To correct drive belt deflection, washers can be

removed or added between the stationary and
movable sheaves of the driven pulley.

„ NOTE: If the drive belt deflection is above speci-
fications, the snowmobile will bog and lack power
at clutch engagement. For good performance,
proper belt deflection is critical.

6. Secure the belt guard.

Drive Train

Schematics

(w/Reverse)

„ NOTE: Determine which type of drive train is
being serviced and refer to the appropriate illustra-
tion for component details; then disassemble and
assemble accordingly. Some components will vary
from model to model. The technician should use
discretion and sound judgment when removing
and installing components.
