RING AND PINION GEAR ASSEMBLYTHEORY

Ring gear and pinions are supplied in matched sets

only. Matching numbers on both pinion and ring gear

are etched for verification. Fig. 40 or 41

If a new gear set is being used, verify the numbers

of each pinion and ring before proceeding with

assembly.

The mounting distance from the center line of the

ring gear to the back face of the pinion for the rear

axle is 109.5 mm.

On the bottom end of each pinion, there is etched a

plus (+) number, a minus (-) number, or a Zero (0)

number, which indicates the best running position

for each particular gear set. This dimension is

controlled by selecting shims, between the inner

pinion bearing cone and pinion gear.

For example: If a pinion is etched +3 (m+8), it would

require 0.003 in. (0.08 mm) less shim than a pinion

etched ‘O’. This means decreasing shim thickness;

increase the mounting distance of the pinion to 4.315

in. (109.6 mm). If a pinion is etched -3 (m-8) it would

require adding .003 in. (.08 mm) more to the shim

than would be required if the pinion were etched ‘O’.

By adding .003 in. (.08 mm), the mounting distance

of the pinion was decreased to 4.309 in. (109.4 mm)

which is just what a -3 (m-8) etching indicated.

To change the pinion adjustment, use different shims

which come in different thicknesses.

Use the tables on next page as a guide for selecting

the correct number of shims to add or subtract from

the old shim pack.
