Abstract
A section of the normal internal bore of a starter pinion gear drive mechanism which allows the drive mechanism to slide over the starter drive shaft is enlarged in diameter. When the pinion gear is shifted to engage the flywheel of an engine, the enlarged bore section slides over a snap ring stop on the drive shaft. The snap ring limits travel of the pinion gear drive mechanism over the drive shaft by engaging the inner end of the enlarged bore. The arrangement allows the use of a short starter drive shaft which reduces interference between the drive shaft and a flywheel or the like. In addition, when the pinion drive mechanism is at rest, the snap ring stop effectively seals the outer end of the enlarged bore thus helping to prevent dirt from reaching the starter drive shaft.
