Description
The Delco PG260 starter motor features small permanent magnets mounted inside the field
frame. These magnets take the place of current-carrying field coils mounted on iron pole
pieces. Internal gear reduction, approximately 4 to 1, through planetary gears results in
armature speeds in the 7000 rpm range. The armature and drive shaft are mounted on roller
or ball bearings in place of bushings. The solenoid switch, plunger, return spring, and shift
lever are permanently mounted in the drive housing.
CAUTION
The starter motor is designed to operate under great overload and produce a high
horsepower for its size. It can do this only for a short time, since considerable heat
accumulates and can cause serious damage. For this reason, the cranking motor
must never be used for more than 30 seconds at any one time. Cranking should not
be repeated without a pause of at least 2 minutes to permit the heat to escape.
