An electric engine starter for cranking an internal combustion engine. The starter has a drive housing which is shaped to define a solenoid compartment and a starter drive compartment. The drive housing has a pair of spaced walls connecting the solenoid compartment to the starter drive compartment. A starter drive that includes a pinion gear and an overrunning clutch is located in the starter drive compartment. A shift lever retainer is located between the spaced walls of the drive housing and pivotally supports a shift lever. The retainer has outwardly projecting ribs and the spaced walls have inwardly projecting spaced ribs. These ribs impede the passage of water from the starter drive compartment to the solenoid compartment. The shift lever has a plate or flap which, in an at-rest position of the shift lever, forms a barrier for the passage of water from the starter drive compartment toward the retainer. The drive housing has two water drain openings that are connected by a drain channel that operates as a sump.

Electric engine starter

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.
