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 machine screw and lock nut securing

the wear strip to the front of the slide rail; then

using a suitable driving tool, drive the wear strip

rearward off the slide rail.

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

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

FZ079A

„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.

3. Remove the front arm limiter straps from the front

arm of the skid frame.

4. Remove the cap screws securing the two front rail

supports to the slide rail.

6. Remove the lock nut and flat washer securing the

front shock axle assembly to the slide rail. Discard

the lock nut.

FZ058A

„NOTE: If it is necessary to remove the cap
screws from the front shock axle 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.

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

securing the spring slide to the rail. Account for a

spacer and the slide block.

FZ059A

„NOTE: If not already done, remove the short
spring leg from the adjusting cam.

8. Note the mounting location for installing pur-

poses; then remove the cap screws and lock nuts

securing the inner idler wheel and mounting block.

„NOTE: On the Sno Pro models, remove the cap
screws and lock nuts securing the second inner
idler wheel and mounting block.

FZ060A

9. Remove the cap screw securing the front arm to

the slide rail.

FZ061A

10. Remove the cap screw from the rear arm limiter.

FZ062A

11. Remove the cap screw securing the rear arm cou-

pler block to the slide rail. Account for the block,

bushing, cap screw, and lock nut.

FZ063A

12. Remove the idler wheel cap; then remove the cap

screw and flat washer securing the rear idler

wheel. Remove the idler wheel; then remove the

adjuster bushing.

FZ064

„NOTE: The adjusting bolt may have to be loos-
ened to remove the adjuster bushing.

13. Remove the torx-head cap screws and lock nuts

securing the track adjuster bracket.

FZ067A

14. Remove the cap screw and lock nut securing the

rear arm assembly to the slide rail.

FZ065A

„NOTE: At this point, the slide rail should be free
of the skid frame components and can be
removed.

„NOTE: If the shock pads must be replaced, refer
to Shock Pads at the beginning of this prodedure.

INSPECTING

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

1. Inspect the slide rail for cracks (A), elongated

holes (B), or unusual bends.

2. Inspect the wear strip for wear. The wear strip

must be 10.7 mm (0.42 in.) thick or thicker. If the

wear strip measurement is less than specified,

replacement of both wear strips is necessary.

then push the rear arm cap screw and the pivot

shock axle cap screw through the mounting holes

in the rail.

4. Install the lock nuts securing the front shock axle

and rear arm assembly to the slide rails. Tighten
