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 specifications.

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.

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

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).

6. Remove the cap screws and lock nuts securing the

front outer idler wheels and the idler wheel mount-

ing blocks. Account for flat washers and spacer

washers.

„NOTE: The idler wheel mounting block should be
removed only from the slide rail being replaced.

MS183A

MS184A

7. Remove the cap screw, washers, and lock nut

securing the front shock mount axle.

MS185A

„NOTE: If it is necessary to remove the cap screw
for replacing the slide rail, install the cap screw
from the opposite side into the assembly to secure
components and aid in replacing the slide rail.

„NOTE: If not already done, remove the short
spring leg from the adjusting cam. Also, it is rec-
ommended that the top cap screw be removed
from the front shock absorber to aid in slide rail
installing.

8. Remove the cap screw and flat washer securing

the spring slide to the rail. Account for a spacer

and the slide block.

MS186A

9. Note the mounting location for installing pur-

poses; then remove the cap screw and lock nut

securing the front inner idler wheel assembly to

the slide rails.

MS187A

9-96

10. Note the mounting position of the front arm

mounting bracket; then remove the cap screws

securing the front arm mounting bracket. Account

for lock nuts.

MS188A

„NOTE: After removing the mounting bracket cap
screw, install the front inner idler wheel assembly
cap screw from the opposite side slide rail (not
being replaced) to hold center components in
place.

MS190A

11. Note the mounting location for installing pur-

poses; then remove the cap screw and lock nut

securing the rear inner idler wheels and mounting

block.

MS189A

12. Remove the cap screws securing the rail supports

to the slide rail.
