SELECTING THE REVERSE 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)
Out of specified value (M0) → Adjust.
Specified value (M0) =
1.80 – R/100 mm
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 trim tab 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.
Example:
If "R" is "+5", then
M0 = 1.80 – (+5)/100 mm
= 1.80 – 0.05 mm
= 1.75 mm
If "R" is "–3", then
M0 = 1.80 – (–3)/100 mm
= 1.80 + 0.03 mm
= 1.83 mm
