Reverse gear shim
NOTE:
Find the reverse gear shim thickness (T2) by
selecting shims until the specified measure-
ment (M) is obtained with the special tool.
1. Calculate:
● Specified measurement (M)
NOTE:
● “R” is the deviation of the lower case
dimension from standard. It is stamped
on the anode mounting surface of the
lower case in 0.01 mm units. If the “R”
mark is missing or unreadable, assume an
“R” value of “0”, and check the backlash
when the unit is assembled.
● If the “R” mark is negative (–), then add
the “R” value to the measurement.
Specified measurement (M) =
1.0 mm – R/100 mm
