Abstract

An engine starter gearing for starting an engine having a starter gear includes a power shaft and a housing affixed on the power shaft. The housing retains an axially displaceable driven clutch member. An internal groove is provided within an open end of the housing. The driven clutch member has an enlarged external diameter portion that fits within the housing. The driven clutch member is held in position by a compressed spring retained within the housing. An installation groove is formed in the driven clutch member spaced away from the enlarged diameter portion. A lock ring is positioned within the housing by first inserting it in the installation groove. The driven clutch member is axially depressed inwardly within the housing, compressing the spring until the locking ring snaps in position in the housing internal groove. The locking ring has an internal diameter that closely fits the external diameter of the driven clutch member forming a grease seal so that as the driven clutch member is axially displaced relative to the housing during starting operations, the escape of grease from the housing is reduced.
