DRIVE PINION GEAR DEPTH SPECIFICATION
Figure 4-2
The pinion setting dimension is measured from the centerline of differential carrier (center line of ring gear) to face of
pinion (button), plus or minus the etch on the button of the pinion. This dimension must be held within ± .002 in (.05
mm). For example: The model 80 pinion setting dimension is 3.500 (88.9 mm). If the pinion etch is a +2, this dimension
becomes 3.502 (88.95 mm).
