9 .
Remove dial indicator (20), 2 bearing caps, depth gaging tools, and front and rear bearings
(1 O and 12) from housing (4).
10.
Check rear face of drive pinion, or painted marking on drive pinion shaft
pinion code number. Calculate drive pinion shim thickness to be used.
Table 6-2. Determining Drive Pinion Shim Requirements
being installed, for
(a) If drive pinion has no plus (+) or minus (-), use exact shim thickness as recorded in
step 8.
(b) If drive pinion is stamped or painted with a plus (+) number, add that many thousandths to
thickness recorded in step 8.
EXAMPLE:
(c) If drive pinion is
thousandths from
EXAMPLE:
If reading from step 8 was 0.019 in. (0.483 mm) and
drive pinion was stamped “+2,” correct shim
thickness is:
0.019 in. + 0.002 in. = 0.021 in.
(0.483 mm + 0.057 mm = 0.534 mm)
stamped or painted with a minus (-) number, subtract that many
thickness recorded in step 9.
If reading from step 8 was 0,031 in, (0.787 mm),
and drive pinion was stamped “-3, ” correct shim
thickness is:
0.031 in. -0.003 in. = 0.028 in.
(0.787 mm -0.076 mm = 0.711 mm)
