Removal
Drain the transmission, remove the clutch
housing and engine assembly. Remove the
wheel and axle housings. Remove the brakes
and brake support plates. Remove the differ-
('ntial bearing carriers.
Pull the be.lri,1~sfrom the carrier. Remove
the pin from the pinion shaft and remove
the shaft. The pinions, side gears and thrust
washers may be moved around to open side
of carrier and removed after the shaft is out.
Inspection
Check
the gear teeth and bearings for wear,
roughness or pitting. Check the pinion and
side gears for backlash clearance. They
should be replaced if backlash is more than
.015" and cannot be compensated by new
thrust washers. Check face of pinions and
side gears and thrust washers and thrust
washer surface in carrier for scoring. Al-
ways use new oil seals.
Assembly-
If a new ring gear is riveted to the carrier
it should be cold riveted. Place the side
gears and pinions in carrier. Rivet the pinion
shaft keeper pin by distorting end of hole.
The gears should have about .005" "backlash
or turned or caused to revolve with a lever
not more than one foot long.
Place the assembly in the case with the ring
gear on the left hand side.
Adjust the bearings by use of the correct
number of shims between the bearing carriers
and transmission case. Adjust to a free roll-
ing fit without end play or binding.
After the bearings are adjusted, the ring gear
mesh may be adjusted by removing a shim
from one side and installing it on the opposite
side. The backlash clearance should be from
.004" to .007". Use a nonsetting sealer be-
tween shims and between shims and case and
ca:l'rier to prevent grease leakage.
