Adjustment Procedure

IMPORTANT: Incorrect axial play may cause the vibration noise. The specification of the axial play is 0.18-0.42 mm (0.0007-0.0165 in).

Clamp DT 46476 (1) on the input shaft so that the measuring base rests on the stator shaft. See Special Tools .
Set the dial gage to 0.
Measure the axial play by pulling and pressing on the handle. Repeat the measurement.
Calculate the measurement values.
Average Example:

M1 = 0.51 mm

M2 = 0.49 mm

M = (0.51 + 0.49)/2 = 0.5 mm

S specification = 0.18-0.42 mm

D adjustment value = 0.5 mm-(0.18-0.42 mm)

So, D is 0.08-0.32 mm.

Calculate the average, so D is 0.2 mm.

IMPORTANT: The disc thickness must be between 0.08 mm-0.32 mm (0.003-0.013 in) thicker. It is sensible to select one with a disc that averages 0.5 mm (0.008 in) thicker than the one that was installed.
Replace the shim.
