Shimming (counter rotation model)
Example:
If “T3” is 0.70 mm, then the pinion shim is
0.68 mm.
If “T3” is 0.74 mm, then the pinion shim is
0.72 mm.
Selecting the reverse gear shim
1. Turn the thrust bearing 1 2 or 3 times to
seat the bearing retainer
2
, and then
measure the bearing height (M1) as
shown.
NOTE:
9
Select the shim thickness (T1) by using the
specified measurement(s) and the calcula-
tion formula.
9
Measure the thrust bearing to seat the
retainer at 4 points to find the height aver-
age.

Make of note the each measurement
numerical.

5. Calculate the pinion shim thickness (T3)
as shown in the examples below.
NOTE:
“P” is the deviation of the lower case dimen-
sion from standard. The “P” mark
a
is
stamped on the trim tab mounting surface of
the lower case in 0.01 mm units. If the “P”
mark is unreadable, assume that “P” is zero
and check the backlash when the unit is
assembled.
Example:
If “M3” is 50.75 mm and “M4” is 30.57 mm
and “P” is (+ 2), then
T3 = 82.00 + (+ 2)/100 – 50.75 – 30.57 mm
= 82.00 + 0.02 – 50.75 – 30.57 mm
= 0.70 mm
6. Select the pinion shim(s) (T3) as follows.
Calculation formula:
Pinion shim thickness (T3) =
82.00 + P/100 – M3 – M4
