SHIM SELECTION (FOR USA AND CANADA)
Forward gear shim
NOTE:
Find forward gear shim thickness (T1) by
selecting shims until the specified measure-
ment (M) with the special tool is obtained.
1. Find the specified measurement (M).
NOTE:
1. F is the deviation of the lower case
dimension from standard. It is stamped
on the trim tab mounting surface of the
lower case in 0.01 mm units. If the F
mark is missing or unreadable, assume
an F mark of “0” and check the backlash
when the unit is assembled.
2. If the F value is negative (–), then sub-
tract the F value from the measurement.
Example:
If F mark is “+5”, then
M = 1.69 + (+5)/100 mm
= 1.69 + 0.05 mm
= 1.74mm
If F mark is “–3”, then
M = 1.69 + (–3)/100 mm
= 1.69 – 0.03 mm
= 1.66 mm
2. Assemble the shimming gauge with the
forward bearing and original shim(s) as
shown in the illustration. Tighten the
nut four turns after contacting the
spring.
NOTE:
If the original shim(s) is unavailable, start
with a 0.50 mm shim.
Specified Measurement (M) =
1.69 mm + F/100 mm
