SHIMMING
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 (M).
Shimming plate ............................
90890-06701
Digital caliper ................................
90890-06704
NOTE:
• Turn the tapered roller bearing outer
race two or three times so that the roll-
ers seat.
Then, measure the height of the bear-
ing, as shown.
• Perform the same measurement at
three points on the tapered roller bear-
ing outer race.
• Find the average of the measurements
(M).
• When using the digital caliper, be sure
to place it at right angles to the shim-
ming plate.
Otherwise, measurement will be incor-
rect.
(2) Calculate the forward gear shim thick-
ness (T1).
Forward gear shim thickness (T1) =
17.5 mm + F/100 mm - M
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 back-
lash when the unit is assembled.
• If the "F" mark is negative (-), then sub-
tract the "F" value from the measure-
ment.
