cleaning solvent. Dry with compressed air.

2. Clean the idler wheel bearings with a clean

cloth.

3. Closely inspect the idler wheel axle for wear,

bends, or damaged threads at either end.

4. Inspect the idler wheels for signs of cracking,

wear, or outer rubber separation from plastic

wheel.

5. Rotate the idler wheel bearings (by hand) and

inspect for any signs of binding or roughness.

! WARNING

Care must be taken when removing the spring from
the adjusting cam or damage or injury could result.

! WARNING

Always wear an approved pair of safety glasses

6. If a bearing must be replaced, use this proce-

dure.

the snap ring.

B. Using a hydraulic press, press the bearing out

the inside of the wheel.

C. Press the new bearing (on its outer race) into

the idler wheel.

MS006A

D. Install the snap ring making sure the “sharp

side” is directed away from the bearing.

MS007A

E. Install the insert (if applicable).

7. Inspect the shock absorber for any signs of oil

leakage especially at the point where the shock

shaft enters the shock body.

8. Inspect the rubber shock bushings located in the

shock absorber eyelets for cracks or deteriora-

tion.

9. Inspect the shock absorber eyelet welds (at each

end) for any cracks or signs of separation.

10. Inspect the welds securing the eyelets of the

shock links for cracks or signs of separation.

Either weld the eyelet or replace the shock link.

11. Inspect the axle surfaces for any signs of corro-

sion. If corrosion is found, lightly buff the sur-

face of the axle with #400 wet-or-dry sandpaper;

then apply a light coat of grease.

MS027

2. Secure the rear shock links and the lower shock

absorber eyelet to the shock pivot bracket by

placing the bushings and shock sleeve into the

shock eyelet; then install the axle links into the

rear shock links. Secure the assembly by install-

ing a cap screw through the shock link assem-

bly, shock pivot bracket and shock eyelet

assembly, and shock link assembly. Secure the

assembly with a lock nut. Tighten securely.

„ NOTE: Do not over-tighten the shock absorber
cap screw as the shock eyelet must be free to
pivot.
