Install the bolts.
Turn the transaxle 180 degrees. N0TE:The adjusting shims are available from 0.1

Measure the differential end float.
1. Using the special tool, lift the differential
assembly.
2. Note the resulting measurement.
Example: 0.73 mm
+ 0.74 mm + 0.72 mm
divided by three
= 0.73 mm.
The value of the thickness of the shim
should be rounded down to the nearest
tenth of a millimeter below if the value ends

ends in 0.06 mm and above.
17. Calculate the required adjusting shim
thickness.
Thickness of adjusting shim = measuring
shim (3.80 mm)
+ average value (0.73 mm)
+ bearing pre-load (0.14 mm) - thickness of
the Belleville washers (4.42 mm)
Example: Adjusting shim = 3.80 mm + 0.73
mm
+ 0.14 mm - 4.42 mm = 0.25 mm.
The thickness of the adjusting shim becomes
0.2 mm (rounded down from 0.25 mm).
18. Separate the transaxle housing.
lnstall the blanking plugs.
Turn the transmission approximately 180
degrees.
19. Using the special tool, remove the
differential bearing cup and the measuring
shim.
*Om ACAUTION:T~~ Belleville washers must
be installed with the inner diameter of both
washers touching.

I. lnstall the Belleville washers.
2. lnstall the measured adjusting shim.
3. lnstall the bearing cone.
Using a suitable center punch, secure the
bearing cone.
