ABSTRACT:
A starter motor includes a housing; an armature shaft having front and rear opposite ends mounted in the housing; armature laminations mounted on the armature shaft; a field coil assembly for causing rotation of the armature shaft, the field coil assembly including three series-connected coils and a shunt coil, all positioned in the housing in surrounding relation to the armature laminations; an inertia style drive mounted on the armature shaft forward of the armature laminations and including a pinion gear for engaging with an engine flywheel during rotation of the armature shaft; a center plate connected to the housing and mounted on the armature shaft between the inertia style drive and the armature laminations; a first ball bearing assembly for mounting the center plate on the armature shaft; a second ball bearing assembly for mounting the front and/or rear ends of the armature shaft in the housing; an oil cap connected to the housing at the front end thereof for providing lubrication of the armature shaft on which the inertia style drive slides; and an elastic seal surrounding the inertia style drive in a light fitting relation and having its outer circumferential surface in sealing contact with the inner wall of the housing for preventing contaminants from contaminating the inertia style drive.
