-- Move the differential up and down, and read the play on the dial gauge and note. (example: 0.70 mm).

Determine the shim according to the table, refer to DIFFERENTIAL, ADJUSTING .

The measurement must be performed as shown in the figure otherwise the measured value will be wrong.

Shim, Determining

-- Remove the transmission housing.

-- Remove the tapered roller bearing outer race from the clutch housing.

A - Support, for example, 22/2

B - Extractor 56-70 mm, for example 21/8

-- First place the washer into the clutch housing.

NOTE:

Note the installed position of the washer, the shoulder on the inner diameter points toward the seal.

-- Then, place the shim of the determined thickness (in the example: 0.95 mm).

The following adjusting shims are available:

Bearing Play	Adjusting Shim
Measured value (mm)	Thickness (mm)
0.359 ••• 0.430 0.431 ••• 0.480 0.481 ••• 0.530	0.65 0.70 0.75
0.531 ••• 0.580 0.581 ••• 0.630 0.631 ••• 0.680	0.80 0.85 0.90
0.681 ••• 0.730 0.731 ••• 0.780 0.781•••0.830	0.95 1.00 1.05
0.831 ••• 0.880 0.881 ••• 0.930 0.931 ••• 0.980	1.10 1.15 1.20
0.981 ••• 1.030 1.031 ••• 1.080 1.081 ••• 1.130	1.25 1.30 1.35
1.131 ••• 1.250	1.40

NOTE:

For the correct shims, refer to the Parts Information.

If the measured shim thickness is larger than those listed in the table, then install two shims that add up to the necessary thickness.

Tolerance variations make it possible to find the exact shim thickness required.
