side of each axle housing). Make sure the adjuster
bushing is positioned properly towards the adjusting
cap screw.
3. Place the rear idler wheels on the axle and secure
with two cap screws (coated with blue Loctite #243)
and washers. Tighten to 20 ft-lb.

Slide Rail

744-844B
REMOVING
NOTE: When replacing one or both slide rails is
necessary, remove one slide rail at a time. The
remaining slide rail will then hold the crossbraces and
brackets in their correct assembly order which is
much quicker than to completely disassemble the
entire skid frame.
1. With the skid frame removed, remove the cap screw,
washers, and lock nut securing the end cap to the
slide rail. Remove the end cap from the slide rail.
