Do not directly use the dimension (i.e.,

7.875) stamped on the nose of the pinion

for calculations when using the pinion

setting gage.

(2)

The dimension (i.e., 7.875) stamped on the pinion indicates the distance from the center of

the differential bearing bores to the pinion bearing shoulder. This dimension must be modified to a

workable value as follows.

(3)

Make a note of the nominal pinion mounting distance dimension stamped on the pinion

nose (fig. 11-52).

Figure 11-52. Establish Nominal Dimension.

(4)

Measure the length of the pinion head. Measure this distance from the nose to the bearing

shoulder using a

3-4

in. micrometer or vernier.

(5)

Mark the

spot on the pinion nose from which the head length measurement was taken.

Later, when using the pinion setting gage, measure to the same spot.

(6) Subtract the

measured pinion head length from the nominal pinion mounting distance noted

in step

(3).

The remainder is the nominal or gaging distance used for calculations when using the pinion

setting gage. See figure 11-52 for the formula.
