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 reverse gear shims
1. Turn the thrust bearing
1
two or three
times to seat the roller bearing
2
, 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 roller bearing at three points to
find the height average.
Calculation formula:
Pinion shim thickness (T3) =
80.00 + P/100 M3 M4
