(2) Install the side holder LH to the left side of
the differential carrier in reverse direction.
(3) Measure the clearance N between the end
of ST2 and the end surface of ST1 by using a
thickness gauge.
NOTE:
Make sure there is no clearance between the case
and ST2.

(4) Obtain the thickness of pinion height adjust-
ing washer to be inserted from the following for-
mula, and replace the temporarily installed
washer with this one.
NOTE:
Adjust it using the 1 — 3 washers.
T = To + N – 0.05 mm (0.0020 in)
T Thickness of pinion height adjusting
washer mm (in)
To Thickness of washer temporally
inserted mm (in)
N Clearance of thickness gauge mm (in)
Memo:
(Example of calculation)
To = 0.15 mm (0.0020 in)
N = 0.1 mm (0.0039 in)
T = 0.15 mm (0.0020 in) + 0.1 mm (0.0039 in) –
0.05 mm (0.0020 in) = 0.2 mm (0.0079 in)
Result: Thickness = 0.2 mm (0.0079 in)
