LOWR
Lower unit

69J1D11
Selecting the reverse gear shims
1.
Calculate the specified value (M0) as
shown in the examples below.
NOTE:
“R” is the deviation of the lower case dimen-
sion from standard. The “R” mark
a
is
stamped on the trim tab mounting surface of
the lower case in 0.01 mm units. If the “R”
mark is unreadable, assume that “R” is zero
and check the backlash when the unit is
assembled.
Example:
If “R” is (+5), then
M0 = 0.50 – (+5)/100 mm = 0.50 – 0.05 mm
= 0.45 mm
If “R” is (–3), then
M0 = 0.50 – (–3)/100 mm = 0.50 + 0.03 mm
= 0.53 mm
2.
Set the shimming tool on the ball bear-
ing.
3.
Measure the clearance (M) between the
shimming tool and the ball bearing
2
as
shown.
NOTE:
Measure the ball bearing at three points to
find the clearance average.
4.
Select the reverse gear shim(s) (T2).
NOTE:
The sum of T2 and M0 should not be more
than M.
Calculation formula:
Specified value (M0) = 0.50 – R/100 mm
Shimming gauge
I
1
: YB-06439
Calculation formula:
Reverse gear shim thickness (T2) =
M – M0
Available shim thicknesses:
0.10, 0.12, 0.15, 0.18, 0.30, 0.40, and
0.50 mm
