CHECK AND ADJUST GEAR LASH
A. Install differential and gear assembly and assemble
cover using new gasket with six bolts equally spaced.
Tighten to specified torque.
B. Check gear lash with dial indicator on universal joint
yoke 2" from pinion shaft center. An indicator reading of
between .013" and .033" will show the recommended
backlash of between .006" and .012" is present in the
gear set.
C. Transpose spacers used in both the case and cover,
decreasing the thickness of the spacer used on the side
in the direction which the gear is to be moved and
increasing the thickness of the opposite spacer exactly
the same amount as required to obtain the correct gear
lash.
D. Install remaining bolts, washers and nuts in housing
assembly and tighten all nuts in bolt circle to specified
torque.
