NOTE
For general assembly instructions, refer to para. 2-16.
Pinion gear depth is the distance from the end face of the pinion
to the center line of the output shafts. The dimension is controlled
by shims between pinion gear rear bearing cup and differential
housing. The pinion gear is etched with two identifying numbers,
the first number identifies ring gear and pinion gear as a matched
set, the second number represents "pinion depth variance" and is
preceded by a plus (+) or minus (-), this number represents the
amount in thousandths the gear set varied from the "standard
setting" 2.547 in. (6.46 cm).
If using original gear set, use original pinion depth shim as a
starter shim and proceed to step 4.
1.
Measure thickness of original pinion depth shim (9) and record for reference.
2.
Check pinion depth variance numbers (8) marked on old and new pinion gears (7) and record for
references.
