30-3. DIFFERENTIAL REPAIR (Contd)
l For general assembly instructions, refer to para. 2-17.
l Pinion gear depth is the distance from end face of pinion to center
line of 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 (-), which represents the amount
in thousandths the gear set varied from the standard setting of
2.547 in. (6.47 cm).
l 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 (3) and record for reference.
Check pinion depth variance numbers (2) marked on old and new pinion gears (1) and record for
