rear arm shock absorber and shock link to the front

arm pivot and account for the sleeves.

7. Remove the cap screw, washer, and lock nut from

the front shock axle; then from one side, tap the

assembly rearward far enough for the axle assem-

bly to clear the slide rails. Account for an axle, two

spacers, two shim washers, and rubber bushing.

„NOTE: It may be necessary to loosen the front
rail support cap screws enough to gain clearance
to remove the front shock axle.

INSPECTING

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

1. Inspect all front arm weldments for cracks or

unusual bends; then inspect the front arm mount-

ing brackets for cracks and for elongated holes.

2. Closely inspect all tubing for cracks or unusual

bends.

3. Inspect the bearings, bushings, and front arm spac-

ers for wear or damage.

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 for body damage and

eyelet weld damage (at each end) for any cracks,

signs of separation, or for unthreading.

INSTALLING

1. With the rubber bushing in the eyelet, install the

axle into the lower shock eyelet bushing assembly;

then install the two shim washers and the two

spacers.

„NOTE: To aid in installing the axle, apply a light
coat of lubricant to the inside of the bushing.

CM246A

2. Place the front arm shock axle assembly into posi-

tion on the skid frame making sure the spacers and

washers are properly positioned. Secure with the

cap screw, washer, and a new lock nut. Tighten to

40 ft-lb.

„NOTE: If the front rail support cap screws were
loosened (after step 6 of removing), treat the
threads with blue Loctite #243 and tighten to 30 ft-
lb.

3. Secure the front outer idler wheel to the idler

wheel mounting block with cap screws, flat wash-

ers, and lock nuts. Tighten to 34 ft-lb.

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.
