4. Inspect the shock absorber for any signs of oil

leakage especially at the point where the shock

shaft enters the shock body.

5. Inspect the shock absorber eyelet welds (at each

end) for any cracks, signs of separation, or for

unthreading.

INSTALLING

1. Secure the shock absorber to the shock bracket

with the cap screw and lock nut. Tighten

securely.

MS086A

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

2. Apply grease to the axle; then install the axle

into the shock bracket. Install the mounting

blocks to the axle.

MS042A

3. Place the idler wheel assembly into position on

the skid frame making sure the mounting blocks

are properly positioned. Secure with the cap

screw, washer, and a new lock nut. Tighten only

until snug.

MS085

4. Position the front arm into the mounting brack-

ets. Secure with cap screws and lock nuts.

Tighten to specifications.

MS087

„ NOTE: At this point, tighten the lock nut (from
step 3) to specifications.

MS088

5. Secure the upper shock eyelet and serrated axle

in the mounting hole of the front arm. Secure

with a cap screw and lock nut. Tighten securely.

9-52

MS039A

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

6. Secure the limiter straps to the rail supports with

cap screws, washers, and lock nuts. Tighten to

specifications.

MS082A

7. Install the skid frame (see Installing Skid Frame

in this sub-section).

„ NOTE: It is advisable to install the rear arm
springs onto the adjuster blocks after the skid
frame has been installed.

Rear Shock Absorber 

and Shock Links

„ NOTE: Before removing the skid frame by using
the Rear Suspension Spring Tool (p/n 0144-311),
remove the spring from the adjusting cam.

„ NOTE: The skid frame must be removed for this
procedure (see Removing Skid Frame in this sub-
section).

DISASSEMBLING

„ NOTE: When removing center components from
the skid frame, it is advisable to loosen all cap
screws/lock nuts from one side of the slide rail to
make removing easier.

1. Disengage the shock absorber at the upper eye-

let and remove the shock absorber. Account for

a sleeve, cap screw, lock nut, and bushings.

MS089A

„ NOTE: For ease of disassembling, it is advisable
at this point to place a block of wood between the
idler arm and the overload springs.

MS090A

MS091

2. Mark the hole that the upper shock links are

mounted in for assembly purposes; then remove

the cap screw and lock nut securing the shock

links to the upper arm bracket. Account for all

mounting hardware.

! WARNING

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

3. Note the hole location that the center inner idler

wheel/pivot assembly is in; then remove the cap

screw, flat washer, and lock nut securing the

assembly to the rails.

MS094A

4. Tap one side of the idler wheel/pivot assembly

forward until it clears the slide rails; then lift the

assembly upward and out from between the

rails.

MS095

„ NOTE: Lay components out in order as they are
removed.

5. With the idler wheel/pivot assembly removed,

remove the three spacers, an axle, and washers

from the pivot bracket.

6. Remove the cap screw, lock nut, and washer

securing the shock rod links to the pivot arm.

Account for all components and mounting hard-

ware.

CLEANING AND INSPECTING

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

1. Clean shock pivot and idler wheel axle in part-

cleaning solvent. Dry with compressed air.

2. Clean the idler wheel bearings with a clean

cloth.

! WARNING

Always wear an approved pair of safety glasses
when using compressed air.

9-54

3. Closely inspect the pivot bracket arm and axles

for wear, bends, or damaged splines 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.

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

dure.

A. Remove 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

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. If

either condition exists, 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.

12. Inspect the pivot assembly for signs of cracks or

elongated holes.

ASSEMBLING

1. Secure the shock rod links (with axles) and the

lower end of the shock absorber to the idler

wheel/pivot assembly with the cap screw and

lock nut. Tighten securely.

MS096A

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

2. Apply a thin coat of low-temperature grease to

the axle and slide the axle and spacer into the

shock pivot bracket. Have equal amounts of the

axle exposed on either side of the pivot bracket

tube.

! CAUTION

Do not remove the bearing unless it is absolutely
necessary. The bearing will be damaged during
removal.
