and avoidable failures at a later date.
Housing, Covers, etc.
Inspect housings, covers and bearing caps to be certain
they are thoroughly cleaned and that mating surfaces,
bearing bores, etc., are free from nicks or burrs. Check all
parts carefully for evidence of cracks or condition which
would cause subsequent oil leaks or failures.
O-Rings
Replacement of O-Rings is more economical when unit is
disassembled than premature overhaul to replace these
parts at a future time. Further loss of lubricant through a
worn seal may result in failure of other more expensive
parts of the assembly. Sealing members should be
