DIFFERENTIALS
(3) Obtain the thickness of pinion height adjust-
ing washer to be inserted from the following for-
mula, and replace the temporarily installed shim
with this one.
NOTE:
Use 1 to 3 shims as required for adjustment.
T = To + N − 0.05 (mm)
where
T = Thickness of pinion height adjusting shim
(mm)
To = Thickness of shim originally installed
(mm)
N = Reading of thickness gauge (mm)
H = Figure marked on drive pinion head
(Example of calculation)
To = 0.15 mm
N = 0.1 mm
T = 0.15 + 0.1 − 0.05 = 0.2 mm
Result: Thickness = 0.2 mm
Therefore use the 32295AA220.
