41.
Rotate front of housing (3) upward 90 degrees. Using driver handle and rear pinion bearing cup
remover, remove rear pinion bearing cup (9) and "starter shim" (8) from housing (3).
42.
Note "pinion depth variance" (10) marked on pinion gear (7). If number is preceded by a plus (+)
sign, add that amount in thousands to "standard setting" 2.547 in. (6.46 cm). If number is preceded
by minus (-) sign, subtract that amount in thousands from "standard setting" 2.547 in. (6.46 cm).
The result of this addition or subtraction is "desired pinion depth". Record for references.
43.
Measure thickness of "starter shim" (8) and add this dimension to "measure pinion depth" (step 20).
Result of this addition is "total measured pinion depth". Record for reference.
44.
Subtract "desired pinion depth" (step 28) from "total measured pinion depth" (step 29). Result of
this subtraction is correct pinion depth shim (8) thickness.
