(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 52 for the formula.

(7)

Continue with procedures using the calculated nominal (gaging) distance and the plus or minus PC varia-

tion.
