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.
