SELECTING THE FORWARD GEAR
SHIMS
NOTE:
Select the shim thickness (T1) by using the
specified measurement(s) and the calcula-
tion formula.
Select:
• Shim thickness (T1)
Selecting steps
(1) Measure (M1).
Shimming plate ........................ 1
90890-06701
Digital caliper ............................ 2
90890-06704
NOTE:
• Turn the roller bearing outer race two or
three times so the rollers seat. Then, mea-
sure the height of the bearing, as shown.
• Perform the same measurement at three
points on the roller bearing outer race.
• Find the average of the measurements
(M1).
(2) Calculate the forward gear shim thick-
ness (T1).
Forward gear shim thickness (T1)
(T1) = 24.6 + F/100 – M1
NOTE:
• "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" value of "0", and check the backlash
when the unit is assembled.
• If the "F" mark is negative (–), then sub-
tract the "F" value from the measure-
ment.
