Example:
If “M1” is 24.10 mm and “F” is (+5), then
T1 = 24.60 + (+5)/100 – 24.10 mm
= 24.60 + 0.05 – 24.10 mm
= 0.55 mm
3. Select the forward gear shim(s) (T1) as
follows.
Example:
If “T1” is 0.55 mm, then the forward gear
shim is 0.52 mm.
If “T1” is 0.60 mm, then the forward gear
shim is 0.58 mm.
Selecting the reverse gear shims
1. Turn the reverse gear
1
two or three
times, and then measure the reverse
gear height (M2) as shown.
NOTE:
• Select the shim thickness (T2) by using the
specified measurement(s) and the calcula-
tion formula.
• Measure the reverse gear at three points to
find the height average.
• Remove the O-ring when the measure-
ment.
2. Calculate the reverse gear shim thick-
ness (T2) 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 unreadable, assume that “R” is zero
and check the backlash when the unit is
assembled.
Example:
If “M2” is 27.95 mm and “R” is (+2), then
T2 = 27.95 – 27.40 – (+2)/100 mm
= 27.95 – 27.40 – 0.02 mm
= 0.53 mm
Calculation formula:
Forward gear shim thickness (T1) =
24.60 + F/100 – M1
