2. Remove the cap screw and lock nut securing the

shock rod links to the idler arm. Account for a

spacer and two axle links.

MS176A

„NOTE: Mark the hole that the upper shock links
are mounted in for assembling purposes.

MS025

3. Remove the cap screw and lock nut securing the

front inner idler wheel assembly to the slide rails;

then from one side, tap the assembly rearward far

enough to clear the slide rails and mounting brack-

ets. Remove the assembly.

MS178

„NOTE: To access the front inner idler wheel
assembly, the front outer idler wheels must be
removed.

MS183A

4. Remove the axle from the shock pivot. Account

for an axle, three spacers, and four washers.

MS179

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

5. With the pivot assembly removed, remove the cap

screw and lock nut securing the lower shock eyelet

and links to the pivot bracket. Account for a spacer

and two link axles.

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.

3. Closely inspect the torque link 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 procedure.

A. Remove wheel insert (if applicable) and the

snap ring.

B. Using a hydraulic press or suitable driving tool,

remove the bearing from 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).

MS008

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 deterioration.

9. Inspect the shock absorber eyelet welds (at each

end) for any cracks or signs of separation.

! WARNING

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

! CAUTION

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

7-62

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 surface

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

apply a light coat of grease.

ASSEMBLING

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

lower end of the shock absorber to the pivot

assembly with the cap screw and lock nut. Tighten

securely.

MS180

„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 into the shock pivot

bracket. Have equal amounts of the axle exposed

on either side of the bracket tube.

FC189

3. Install a washer (A), idler wheel (B), washer (C),

and spacer (D) to each side of the pivot bracket

(E).

MS179A

4. Lower the pivot assembly down between the rails.

Align the axle with the mounting hole (as noted

during disassembling). Secure with the cap screw

and a new lock nut. Tighten to 40 ft-lb.

MS993

5. Position the rear arm/idler arm so the rear springs

can be installed into the slide blocks.

6. Position the shock links in the appropriate holes of

the idler arm brackets (as noted in disassembling).

Place a spacer between the center of the brackets;

then insert the link axles into the upper shock link

eyelets. Secure with a cap screw, washer, and lock

nut. Tighten securely.

MS176A

7. Secure the shock absorber to the idler arm with

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

Tighten securely.

7-63

MS175A

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

739-992A

Slide Rails

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

REMOVING

„NOTE: When it is necessary to replace one or
both slide rails, it is recommended that one slide
rail be removed at a time. The remaining slide rail
will then hold the crossbraces, axles, and brackets
in their correct assembly order. Always mark the
mounting hole locations during disassembly to
speed up the assembly process and to prevent any
damage. This method is much quicker than to
completely disassemble the entire skid frame. To
replace either rail, use the following procedure.

1. Remove the end cap from the slide rail. Account

for a cap screw, lock nut, and two flat washers.

MS016A

2. Remove the machine screw and lock nut securing

the wear strip to the front of the slide rail.

MS213A

3. Align the wear strip with the openings (windows)

in the track; then using a suitable driving tool,

drive the wear strip rearward off the slide rail.

„NOTE: If binding of the wear strip occurs, it may
be necessary to use a pipe wrench, start from
either end, and hook the edge of the wear strip
with the pipe wrench jaw and twist the wear strip
off the slide rail. Move the pipe wrench 7.5 cm (3
in.) and again twist the wear strip off the rail.
Repeat this procedure until the wear strip is free of
the rail.

4. Remove the cap screws and lock nuts with flat

washers from the lower limiter straps.

MS161A

5. Remove the cap screws securing the rail support to

the slide rail.

! CAUTION

When installing the shock and shock rod links to the
idler arm, make certain that the pivot assembly is
positioned correctly (in the UP position).
