Removal
Note: The following procedure is applicable to all top 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. Jack up the track high enough to permit roller removal.
Put wooden blocks between track link and side frame.
3. Remove the mounting bolts, and tap the upper roller with
a copper mallet to separate it from the side frame.
4. Fasten a sling to the upper roller, and completely remove
the upper roller bolt and remove the upper roller.
