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.

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.

ing block.
