Shimming
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 forward gear shim
1.
Turn the taper roller beaning outer race
1
2 or 3 times to seat the rollers, 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 bearing outer race at 4 points
to find the height average.
9
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 46.65 mm and “M4” is 15.15 mm
and “P” is (+ 2), then
T3 = 62.5 + (+ 2)/100 – 46.65 – 15.15 mm
= 62.5 + 0.02 – 46.65 – 15.15 mm
= 0.72 mm
6.
Select the pinion shim(s) (T3) as follows.
Calculation formula:
Pinion shim thickness (T3) =
62.5 + P/100 – M3 – M4
