All parts cleaned must be thoroughly dried immediately by
using moisture-free compressed air or soft, lintless
absorbent wiping rags free of abrasive materials such as
metal filings, contaminated oil or lapping compound.
The importance of careful and thorough inspection of all
parts cannot be overstressed. Replacement of all parts
showing indication of wear or stress will eliminate costly
and avoidable failures at a later date.
Carefully inspect all rollers, cages and cups for wear,
chipping or nicks to determine fitness of bearings for
further use. Do not replace a bearing cone or cup
