Removal
Note: The following procedure is applicable to all bottom
rollers, but as there are visual differences, the illustrations
show only a typical unit.
1. Slacken the check valve to bleed out grease.
! WARNING !
When opening the check valve always stand to one side
and loosen a little at a time until grease starts to come
out. If you over-loosen too much, grease could spurt out
or the valve cover fly out and cause serious injury.

2. Lift the side of the undercarriage high enough to permit
bottom roller removal. Support with wooden blocks.
3. Remove the mounting bolts, and tap the bottom roller
with a copper mallet to separate it from the side frame.
4. Remove the roller.
