Sd Series

Fig. 1 Exploded View Of AC-Delco SD Starter Motor (SD260 Shown):

DESCRIPTION
The AC-Delco SD series starter, Fig. 1, is a direct drive unit with electromagnet fields. This starter has a extruded field frame and an overrunning clutch type drive. The overrunning clutch is operated by a solenoid switch mounted to a flange on the drive housing.

OPERATION
The solenoid is attached to the drive end housing by two screws. The cover can be removed to inspect the contacts and contact disc, but the switch is serviced as assembly only.

Most motors of this type have graphite and oil impregnated bronze bearings which ordinarily require no added lubrication except at time of overhaul when a few drops of light engine oil should be placed on each bearing before reassembly.
