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

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.
