Abstract
An engine starter drive assembly is disclosed of the type including a pinion gear moveable from a rest position to a driving position to engagement with gear teeth formed on an engine flywheel, the pinion adapted to be rotated by the starter motor in order to start the engine after engaging the flywheel teeth. In order to be properly located with respect to the flywheel gear teeth, the pinion gear moves axially into engagement with a fixed stop located at a predetermined position to produce proper engagement of the pinion with the flywheel teeth. The starter also includes an antidrift compression spring and washer assembly biasing the pinion gear against axial movement out of the retracted position. The disclosed starter assembly features a shielding cup supported on the fixed stop and extending towards the pinion gear hub extension to enclose the space therebetween, preventing the build-up of foreign matter tending to interfere with the axial movement of the pinion gear. In the preferred embodiment, the cup is axially fixed to the fixed stop and a hub extension of the pinion gear slides into the cup during axial movement of the pinion gear during initiation of a starting cycle.
