CLEANING AND INSPECTION
Clean the transmission case thoroughly, using a
suitable solvent, dry with compressed air. Inspect the
case for cracks, stripped threads in the various bolt
holes and the machined mating surfaces for burrs,
nicks or any condition that would render the case
unfit for further service. The front mating surface
should be smooth; if any burrs are present, dress them
off with a fine mill file. If threads are stripped, install
Helicoil inserts.
Ball Beurings
blow dry with compressed air.
Wash the ball bearings, using a clean solvent and
CAUTION: Do not spin the bearings with air pres-
sure; turn slowly by hand. Spinning unlubricated
bearings may cause damage to the races and the
balls.
Be sure the ball bearings are clean, then lubricate
them with light grade engine oil. Inspect the bear-
ings for roughness. This can best be determined by
slowly turning the outer race by hand. Measure the
fit of the bearings on their respective shafts.
Needle Type Bearing Rollers and Spacers
Inspect all bearing rollers for flat spots or brinel-
ling. Inspect all bearing roller spacers for signs of
wear or galling. Install new parts as required.
Gears
Inspect the gear teeth on the synchronizer clutch
gears and stop rings. If there is evidence of chipping
or excessively worn teeth, install new parts at reas-
sembly. Be sure the clutch sleeve slides easily on the
clutch gear. Inspect the countershaft gear and all slid-
ing gear teeth for chipped or broken teeth, or show-
ing signs of excessive wear. Small nicks or burrs must
be stoned off.
Inspect the teeth on the main drive pinion. If ex-
cessively worn, broken or chipped, a new pinion
should be installed.
Test the interlock sleeve and pin for free move-
ment in the bore of the shift housing. Examine the
detent balls for signs of brinelling. If the lever de-
tents show signs of excessive wear to the extent
