Shimming
NOTE:
• Shimming is not required when assembling
the original lower case and inner parts.
• Shimming is required when assembling the
original inner parts and a new lower case.
• Shimming is required when replacing the
inner part(s).
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 (M)
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 thickness
(T1) as shown in the examples below.
NOTE:
“F” is the deviation of the lower case dimen-
sion from standard. The “F” mark
a
is
stamped on the trim tab mounting surface of
the lower case in 0.01 mm units. If the “F”
mark is unreadable, assume that “F” is zero
and check the backlash when the unit is
assembled.
Example:
If “M” is 26.06 mm and “F” is (+1), then
T1 = 26.50 + (+1)/100 – 26.06 mm
= 26.50 + 0.01 – 26.06 mm
= 0.45 mm
3.
Select the forward gear shim(s) (T1) as
follows.
