CLEANING AND INSPECTION
CLEANING
Clean all parts thoroughly using solvent type cleaning fluid. It is recommended that parts be immersed in cleaning fluid and
agitated slowly until parts are thoroughly cleaned of all old lubricants and foreign materials.
Thoroughly dry all cleaned parts immediately by using moisture-free compressed air or soft lint-free absorbent wiping rags free
of abrasive materials such as metal filings, contaminated oil, or lapping compound.
BEARINGS
Remove bearings from cleaning fluid and strike larger side of cone flat against a block of wood to dislodge solidified particles
of lubricant. Immerse again in cleaning fluid to flush out particles. Repeat above operation until bearings are thoroughly clean.
Dry bearings using moisture-free compressed air. Be careful to direct air stream across bearings to avoid spinning. DO NOT
SPIN BEARINGS WHEN DRYING. Bearings may be rotated slowly by hand to facilitate the drying process.
HOUSINGS, COVERS, AND CAPS
Clean interior and exterior of housings, bearing caps, etc., thoroughly. Cast parts may be cleaned in hot solution tanks with mild
alkali solutions, providing these parts do not have ground or polished surfaces. Parts should remain in solution long enough to
be thoroughly cleaned and heated. This will aid the evaporation of the cleaning solution and rinse water. Parts cleaned in solu-
tion tanks must be thoroughly rinsed with clean water to remove all traces of alkali. Cast parts may also be cleaned with steam
cleaner.
All parts cleaned must be thoroughly dried immediately by using moisture-free compressed air or soft lint-free absorbent wiping
rags, free of abrasive materials such as metal filings, contaminated oil, or lapping compound.
INSPECTION
The importance of careful and thorough inspection of all parts cannot be overstressed. Replacement of all parts showing indi-
cation of wear or stress will eliminate costly and avoidable failures at a later date.
BEARINGS
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 INDIVIDUALLY without replacing the mating cup or cone at the same time. After
inspection, dip bearings in clean light oil and wrap in clean lint-free cloth or paper to protect them until installed.
OIL SEALS, GASKETS AND RETAINING RINGS
Replacement of spring load oils seals, “O” rings, metal sealing rings, gaskets and snap rings is more economical when the 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 mem-
bers should be handled carefully, particularly when being installed.
Cutting, scratching or curling under of lips of seals seriously impairs its efficiency.
When assembling new metal type sealing rings, these should be lubricated with a coat of chassis grease to stabilize rings in
their grooves for ease of assembly of mating members. Lubricate all “O” rings and seals with recommended type Automatic
Transmission Fluid before assembly.
GEARS AND SHAFTS
If Magna-Flux or a dye penetrant process is available, use this process to check parts. Examine teeth and the ground/ polished
surfaces of all gears and shafts carefully for wear, pitting, chipping, nicks, cracks, or scoring. If gear teeth are cracked or show
spots where case hardening is worn through, replace with new gear. Small nicks may be removed with suitable hone stone.
Inspect shafts to make certain they are not sprung, bent, or have twisted splines.
HOUSINGS, COVERS, AND CAPS
Inspect housings, covers, and 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 conditions which can cause oil leaks or failures.
Care should be exercised to avoid skin rashes, fire hazards, and inhalation of vapors when using solvent type and alkali clea-
ners.
