(3) Measure the specified measurement
(M).
2. Adjust:
• Shim thickness (T1)
Remove or add shim(s).
NOTE:
(M0) – (M) should be as close to “0” as pos-
sible.

and 0.50 mm
SELECTING THE REAR GEAR SHIMS
NOTE:
Find the shim thickness (T2) by selecting
shims until the specified value (M0) is
obtained with the special tool.
1. Measure:
• Specified measurement (M)

Measuring steps
(1) Calculate the specified value (M0).
NOTE:
• “R” is the deviation of the lower case
dimension from standard. It is stamped
on 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 (M0) =
1.60 – R/100 mm
