25. Force the driven shaft toward the PTO-side

(rotating the shaft to prevent the brake disc from

binding on the shaft) until brake disc is free.

Account for the key.

26. Continue to slide the driven shaft until it is out

of the PTO-side. Account for a bearing, two

flange plates, and the PTO-side driven shaft col-

lar; then remove the skid frame from the tunnel

(see Section 9).

27. Remove the three PTO-side lock nuts securing

the driveshaft flange bearing assembly and cable

adapter. On models with a standard speedome-

ter, remove the adapter and speedometer cable.

AF053

„ NOTE: On models with an electronic speedome-
ter, remove the three lock nuts securing the volt-
age regulator/speedometer pick-up module; then
remove the module.

28. Tap the driveshaft toward the chain case to unseat

the MAG-side bearing. Remove the bearing.

29. Slide the driveshaft toward the MAG-side until

the PTO-side of the driveshaft is out of its

mounting hole. Tilt the end of the driveshaft

away from the tunnel and slide the driveshaft

free of the tunnel. Remove the track.

AF055

30. Scribe a line on the driveshaft along the edge of

each sprocket to aid in assembly. Loosen the set

screw on the collar and drive the collar clock-

wise until free; then remove the bearing and

flange plates from the driveshaft.

31. Press the sprockets off the driveshaft.

CLEANING AND INSPECTING

„ NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.

1. Thoroughly wash all metallic components in

parts-cleaning solvent. Dry using compressed air.

2. Wash all non-metallic components with soap

and water.

3. Inspect the driveshaft and driven shaft for dam-

aged splines or stripped threads.

4. Inspect the bearings for any roughness or dam-

age.

8-36

5. Inspect the seals for any breaks or damage.

6. Inspect the track for cuts, gouges, or wear.

7. Inspect the keyways in the driven shaft for wear

or damage.

8. Inspect the brake disc for wear or cracks.

9. Inspect the track drive sprockets for wear or

damage.

10. Inspect the top sprocket for any chipped or worn

teeth.

11. Inspect the bottom sprocket teeth for wear. Turn

the inner sprocket bearing by hand and inspect

for any signs of being rough.

12. Inspect the three bottom sprocket drive pins.

Check the pin edges for chipping and wear.

13. Inspect the drive pin springs for tension by

pushing each pin into the sprocket and releasing

it. It must snap back out without any signs of

binding. If any of these items (pins, bearing,

sprocket, teeth) appear worn, replace the

sprocket as an assembly.

AI019

14. Inspect the idler gear sprocket teeth and bear-

ings. Rotate the inner bearings by hand. Check

each sprocket tooth for any signs of chipping

and wear.

15. Closely inspect the drive chain for broken links.

16. Inspect the reverse gear. Inspect the teeth for

wear and chipping. Inspect the edges of drive

pin holes for any signs of chipping and wear.

17. Remove the snap ring from the reverse gear.

Remove the outer thrust washer, thrust bearing,

and inner thrust washer. Inspect the thrust bear-

ing by placing it between the two thrust washers

and rotating the thrust washer. Rotation must

feel smooth. If any roughness is noted, replace

the thrust washers and bearing as a set.

18. Inspect the chain tightener bearing. Rotate the

tightener roller and check for smooth rotation. If

rotation feels rough, replace roller and bearing

assembly.

ASSEMBLING

1. Press the sprockets on the driveshaft noting the

scribed marks on the shaft and the timing mark

found on one tooth of each sprocket. The timing

mark is the letter T molded into the outer surface

of one drive tooth. All the T markings must be

in alignment.

„ NOTE: Make sure all sprockets are installed cor-
rectly to ensure correct timing of the sprockets.
The bearing is positioned between the flange
plates.

2. Assemble the driveshaft components on the

PTO-side of the driveshaft. Install the bearing

lock collar; then install the flange bearing

assembly with the bolts facing towards the tun-

nel.

AF055

3. Position the front of the track up into the tunnel.

Install the driveshaft with the splined end

through its mounting hole in the chain case.

4. Place the PTO-side of the driveshaft into posi-

tion by sliding the bolts of the flange bearing

assembly through the holes in the tunnel.

5. On models with a standard speedometer, place

the cable adapter into position on the flange

bearing assembly bolts. Secure with three lock

nuts. Tighten to specifications.

AF053

„ NOTE: On models with an electronic speedome-
ter, place the voltage regulator/speedometer pick-
up module into position. Install and tighten the
three lock nuts to specifications.

6. Slide the MAG-side bearing onto the driveshaft

(inner race flange must be positioned toward

drive chain); then install the O-ring and flange

plate. Secure with three carriage bolts and lock

nuts. Tighten to specifications.

„ NOTE: Prior to installation, lubricate the O-ring
with Low-Temp Snowmobile Grease (p/n 0636-
593).

7. Install the brake hub key into the driven shaft

keyway; then slide the driven shaft into position

through the PTO-side bearing bracket. Position

the brake disc between the brake pads; then slide

the driven shaft through the brake disc until

fully seated. 

8. Install the PTO-side bearing with collar and

flange plates on the driven shaft; do not tighten

the collar at this time. Secure the PTO-side bear-

ing and flange plates with two carriage bolts and

lock nuts. Tighten to specifications.

9. On the MAG-side driven shaft, install the bear-

ing, O-ring, and flange plate. Secure with three

lock nuts. Tighten to specifications.

„ NOTE: Prior to installation, lubricate the O-ring
with Low-Temp Snowmobile Grease (p/n 0636-
593).

„ NOTE: If washers were removed from behind the
upper sprocket, install them at this time.

10. Install the spacer washer on the driveshaft.

AF090

11. Install the bottom sprocket and driveshaft exten-

sion.

AF427

12. Position one shim washer on the idler gear shaft.

AF430

13. Position the chain around the lower reverse

sprocket; then place the idler sprocket and top

sprocket into the chain. Slide sprockets into

position on the idler shaft and driven shaft.

AF441

„ NOTE: If the chain tension is too tight to allow
installation of the top sprocket, remove the PTO-
side driven shaft bearing. This will allow the driven
shaft to be lifted at the PTO-side and will allow the
sprocket to slide onto the splined end of the driven
shaft.

14. Secure the top sprocket with a spring washer

(with the high side directed away from the

sprocket) and lock nut (coated with green Loc-

tite #609). Tighten the lock nut to specifications.

! CAUTION

Tighten the flange plate nuts evenly or the O-ring
seal may be damaged.
