IN SP EC T IO N
Prior to assembly of the transmission, the individual parts
should be carefully checked to eliminate those damaged from
previous service. Broken parts are often the result and not the
cause of the trouble. This inspection procedure should be
carefully followed to ensure the maximum of wear life from
the rebuilt unit.
All components of the transmission (except bearing assem
blies) should be thoroughly cleaned with cleaning solvent and
dried with air pressure.
Whenever available, the Magna-Flux method should be
used on all parts, except ball and roller bearings. This method
is especially suited for detecting minute cracks and wear on
highly finished or ground surfaces, which otherwise would
not be visible to the naked eye. Check all components for
discoloration or warpage due to heat or binding.
Bearings
Bearings should always be cleaned separately from other
transmission components in CLEAN cleaning solvent.
NOTE: Steam or water is not recommended for
cleaning bearings as they usually rust in a very short
time.
1.
Slush bearings in solvent until all old lubricant is loos
ened. Hold bearing races so bearings will not rotate;
then brush bearing with a soft bristled brush until all
