(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

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

until
there is
no
clearance
among them.
