For example, if the old pinion is marked -3 and the

new pinion +2, chart procedure would be as follows:

Refer to Old Pinion Marking column at left side of chart

and locate -3 figure in this column. Then read to right,

across chart, until under +2 figure in New Pinion Mark

ing column. Box where two columns intersect is amount

of shim thickness change required. In this case, the

number in the intersecting box is -0.005 (0.12 mm) which

represents the amount to be subtracted from the old

shim thickness. If the box number had been a + figure,

this amount would be added to the old shim thickness.

(1) Measure thickness of pinion depth shim re

moved during disassembly.

(2) Note pinion depth variance numbers marked on

old and new pinion gears.

(3) Refer to Pinion Variance Chart and determine

amount to be added or subtracted from original shim for

desired starter shim thickness.

NOTE: Do not use the starter shim thickness deter

mined by the pinion variance chart as the final shim

setting. The actual pinion depth measurement must be

performed and final shim thickness adjusted as

(4) Install rear bearing on pinion gear with large

diameter of bearing cage facing gear end of pinion. Press

bearing against rear face of gear.
