CAUTION

Do not allow gear (13) to fall; gear may stay attached
to the drive housing or to the motor.

Do not lose the thrust balls (2a or 41) or let them fall
between the gears, which will damage the drive
housing if not removed. The balls, which are heavily
covered with grease, usually stay in the gear re-
cesses, but could be dislodged. If the balls are not in
place, the bearings will wear prematurely.

SAE non-detergent oil. Pack roller bearing and
gears with grease supplied.

NOTE:

 The gears and bearings between the drive

housing (2) and motor front end bell (C) should contain
a total of 3 fl oz (89 cc) of grease.

11. Place large washer (6) and then small washer (7)

on crankshaft (5).

12. Rotate crank to top of stroke and insert crankshaft

(5). Align gears and push drive housing (2) straight
onto motor and locating pins. Install screws (16, 3)
and their lockwashers (4). Torque to 80 in-lb (9
