6. REMOVE SCREWS (S73) AND WASHERS (S72).
7. PULL MOTOR (S71) STRAIGHT OUT AND OFF MOTOR SOCKET
PLATE (S37).
8. REMOVE 0-RING (S38).
9. REMOVE PINION (S70) FROM MOTOR (S71):
NOTE: Pinion is matched to the gear reduc-
tion unit. If a new motor is going to be
installed, mount the old pinion on the new
motor shaft. If a new gear reduction unit is
going to be installed, mount the new pinion
that comes with it on the motor shaft.
a. Remove screw (S68). Use a strap wrench to hold pinion from
rotating while removing screw.
b. If pinion (S68) is tight on motor (S71) shaft, screw an M10x150
screw into threaded hole and pull pinion from motor shaft with the
help of a small puller. Use the key slot hole in the side of the pin-
ion to engage one jaw of the puller.
CAUTION: DO NOT HIT OR TAP MOTOR SHAFT.
c. Pinion (S70) is matched to gear reduction unit (S35), so keep it
for re-assembly. If a new motor is to be installed, mount old pinion
on new motor shaft.
