REAR AXLE DRIVE PINION AND BEARINGS MAINTENANCE (ALL EXCEPT
M1009) (Con’t).
2 .
Compare depth code number with number on original drive pinion (9). Using Table 6-4, select
proper shim for preliminary setting of pinion depth,
NOTE
If code number on old and new drive pinion (9) are the same, original
shim may be reused if undamaged.
3 .
Refer to thickness of shim as measured in REMOVAL, step 2. Increase
thickness as indicated by Table 6-4:
Table 6-4. Determining Drive Pinion Shim Requirements
or decrease shim
EXAMPLE 1.
EXAMPLE 2.
If original shim measured 0.014 in. (0.36 mm),
original code was “- 1,” and new code is “+2, ”
correct shim would be:
0,014 in. + 0.003 in. = 0.017 in.
(0.36 mm + 0.08 mm = 0.43 mm)
If original shim measured 0.012 in. (0.30 mm),
original code was “+2, ” and new code is “–2,”
correct shim would be:
0.012 in. -0.004 in. = 0,008 in.
(0,30 mm -0.010 mm = 0.20 mm).
