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 46.68 mm and M4 is 32.49 mm
and P is (5), then
T3 = 80.00 + (5)/100 46.68 32.49 mm
= 80.00 0.05 46.68 32.49 mm
= 0.78 mm
6. Select the pinion shim(s) (T3) as follows.
Example:
If T3 is 0.53 mm, then the pinion shim is
0.52 mm.
If T3 is 0.78 mm, then the pinion shim is
0.75 mm.
Selecting the forward gear shims
1. Turn the taper roller bearing outer race
1
two or three times to seat the rollers,
and then measure the bearing height
(M1) as shown.
NOTE:
Select the shim thickness (T1) by using the
specified measurement(s) and the calcula-
tion formula.
Measure the bearing outer race at three
points to find the height average.
2. Calculate the forward gear shim thick-
ness (T1) as shown in the examples
below.
Calculation formula:
Pinion shim thickness (T3) =
80.00 + P/100 M3 M4
