Before placing spring washers, crown nuts, and split pins, it is strongly recommended to close motor openings with a tape, as show on photo in previous chapter to prevent that any of the small parts could enter the motor, if it falls through the fingers by coincidence. When this happen, it is usually necessary to remove and open motor, which is quite demanding job, so it is much easier to tape openings.
