Fig. 9 Exploded View Of Delco-Remy SD-260 Series Starter Motor:

The Delco-Remy starter motor, Figs. 1 through 9, 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 permanent magnet gear reduction starter has a gear reduction assembly to achieve free speed of up to 7000 RPM. The diesel starters, 25MT and 27MT, have a center bearing.

Fig. 10 Solenoid Contact Assembly:

The solenoid, Fig. 10, 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 an 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.
