Starting System: Description and Operation

Fig. 1 Delco-Remy Starter Motor:

The Delco-Remy starter, Fig. 1, has the solenoid shift lever mechanism and the solenoid plunger enclosed in the drive housing to protect them from exposure to road dirt, icing conditions and splash. They have an 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.
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.
