ABSTRACT:
A dynamoelectric machine in the form of a windshield wiper motor having an armature shaft with a worm driving a worm gear mounted in a gear end housing. The armature shaft bearing is positioned against a shoulder on the shaft by a washer and push-on retainer. The bearing is slip-fit mounted in the gear end housing and a U-shaped retainer is mounted in a slot in the gear end housing adjacent the bearing such that the retainer engages the bearing to retain it against axial loading on the shaft. A bowed washer is mounted to engage the bearing to urge it against the retainer.
