CLEANING

Clean the gears, bearings, shafts, synchronizers, thrust washers, oil feeder, shift mechanism, gear case, and bellhousing. Do not use solvent to clean sealed bearings. Dry all parts except the bearings with compressed air.

Allow the bearings to either air dry or wipe them dry with clean shop towels.

INSPECTION

Inspect the gears, bearings and shafts. Replace the bearings and cups if the rollers are worn, chipped, cracked, flat spotted, brinnelled, or if the bearing cage is damaged or distorted. Replace the gears if the teeth are chipped, cracked or worn thin. Inspect the synchronizers. Replace the sleeve if worn or damaged in any way. Replace the stop rings if the friction material is burned, flaking off, or worn. Check the condition of the synchro keys and springs. Replace these parts if worn, cracked, or distorted.
