Replacing Jackshaft Bearings
• There are two setscrews in each bearing lock
collar. Tighten one setscrew in each collar and
remove the other setscrew. Punch a start point
in the shaft and drill 3/8” diameter hole in
jackshaft just deep enough for setscrew to enter
shaft. Take care not to damage the screw
threads. Replace setscrew with LocTite 242
and tighten. Do this for all four setscrews. This
will help prevent shaft from spinning and
walking inside of bearing.
