NOTE:
9 Shimming is not required when assembling
the original lower case and inner parts.
9 Shimming is required when assembling the
original inner parts and a new lower case.
9 Shimming is required when replacing the
inner part(s).
Selecting the pinion shims
1. Install the special service tools onto the
pinion gear 1.
NOTE:
9 Remove the shim(s) 2 from pinion gear,
then measuring.
9 Attach the pinion height plate with its hollow
facing to the pinion gear.
9 Select the shim thickness (T) by using the
specified measurement(s) and the calcula-
tion formula.
2. Measure the distance (M) between the
special service tool and the pinion as
shown.
3. Calculate the pinion shim thickness (T)
as shown in the examples below.
Example:
If “T” is 26.06 mm,
T =26.06 - 24.50
=1.56
4. Select the pinion shim(s) (T) as follows.
Example:
If “T” is 1.65 mm, then the pinion shim is
1.60 mm.
If “T” is 1.56 mm, then the pinion shim is
1.55 mm.
Selecting the forward and reverse
gear shims
NOTE:
Select the forward and reverse gear shim
thickness by measuring the backlash.
