shift socket roll pin. Install a new pin during reas-

Output Shaft And Geartrain
Inspect all of the gears for worn, cracked, chipped,
or broken teeth. Also check condition of the bearing
bore in each gear. The bores should be smooth and
free of surface damage. Discoloration of the gear
bores is a normal occurrence and is not a reason for
replacement. Replace gears only when tooth damage
has occurred, or if the bores are brinnelled or
severely scored.
Inspect the shaft splines and bearings surfaces.
Minor nicks on the bearing surfaces can be smoothed
with 320/420 grit emery and final polished with cro-

aged or bearing surfaces are deeply scored, worn, or
brinnelled.
