Case, Cover and Bearing
Cups-Transfer case, cover, and
bearing cups must be thoroughly cleaned in solution to
remove all accumulation of lubricant and dirt. Remove
all trace of gaskets from surfaces where used.
Inspection-Carefully inspect all bearings and rollers for
evidence of chipping, cracks, or worn spots that would
render bearing unfit for further service. Bearings are
non-adjustable and if worn or damaged, must be
replaced with new parts.
Inspect shaft splines and gears. If any indication of
failure, such as chipped teeth or excessive wear, is
indicated, those parts should be replaced with new parts.
