(1) Shim thickness (T1) measurement of output shalt
(a) Measure the bearing insertion hole depth
(A)
of the
mounting flange, and the bearing insertion hole
depth (A) of the clutch case.
(b) Measure the length (8) between the bearing outer
race of the input shaft assembly.
(c) Obtain the (T1) thickness
by
the following formula:
T1
=
A+A'-B
(T1: Clearance

(2) Shim thickness (T2, T3) measurement of output shaft
(a) Measure the bearing insertion hole depth (C) of
the mounting flange, and the bearing insertion hole
depth (C') of the clutch case.
(b) Measure the length (0) between the bearing
outer races.
NOTE : Tighten the mounting flange nut of the output
shaft assembly with the specified torque. Press-
fit the inner race of the clutch case roller bearing
to the large gear side .

(c) Measure the (F} and (E) length from the outer race
end of the clutch case bearing included in the out-
put shaft assembly.
NOTE : Before measuring the (F) and (E) length, press
the forward large gear and the reverse large gear
to the drive cone until there is no clearance
among them.
