Abstract
A starter drive for cranking an engine. The starter drive has a pinion. A bushing is press fitted to the bore of the pinion. The pinion and bushing are supported for rotation and sliding movement by a shaft or sleeve. A thin film of grease is located between the inner surface of the bushing and the outer surface of the shaft or sleeve. The inner surface of the bushing has a plurality of contaminant collecting grooves. The grooves collect the contaminants to thereby prevent grease degradation and wear out.
