c. Seat the mainshaft fully by tapping its end
with a plastic hammer.
d. Thread the mainshaft holder bolt in until it
just contacts the wide surface of the main-
shaft base.
e. Zero a dial gauge on the end of the mainshaft.
f. Turn the mainshaft holder bolt clockwise; stop
turning when the dial gauge has reached its
maximum movement. The reading on
gauge is the amount of mainshaft end play.
CAUTION: Turning the shaft holder bolt more
than 60 degrees after the needle of the dial
gauge stops moving may damage the
transmission.
g. If the reading is within the standard, the
clearance is correct.
If the reading is not within the standard, recheck
the shim thickness.
