ABSTRACT:
An electric engine starter that has a motor frame and a planetary gear mechanism is provided with an internal shield that is operative to prevent brush dust from entering the planetary gear mechanism. The shield is formed of steel and has an outer annular flange that, prior to assembly to the starter, is located at an angle to a plane that is normal to the longitudinal axis of the shield. When the shield is assembled to the starter, it is compressed between the motor frame and a support for the ring gear of the planetary gear mechanism. During this compression, the flange is deflected to develop a spring force. This spring force causes a gasket interposed between the flange and the motor frame to tightly seal against the motor frame. This spring force further causes the shield to tightly engage the ring gear support.
