Starters

Description

The Delco PG 200 and PG260 starter motor features
small permanent magnets mounted inside the field
frame. These magnets take the place of current-car-
rying field coils mounted on iron pole pieces. Internal
gear reduction, approximately 4 to 1, through plane-
tary 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 bush-
ings. The solenoid switch, plunger, return spring, and
shift lever are permanently mounted in the drive
housing.
