Safety Warning

Starting System - DELCO-REMY: Description
For identification, starter part numbers are stamped on the outside of the frame or on an identification label attached to the frame.
Six types of starters are used: SD-200/210/250/260/300 and 28MT series. The first series is designated SD (Straight Drive) because the pinion is driven directly by the armature shaft. Wound field coils energize pole pieces that are arranged around the armature. These are used on gasoline engines.
The 28MT starter has a pinion that is driven by a gear reduction system. This starter is used on diesel engines. The 28MT starter should not be dissembled for any reason and is serviceable only by complete replacement.
