The PG260 starter motor features small permanent magnets mounted inside the field frame and a planetary gear reduction mechanism between the armature and drive. A permanent magnet gear reduction motor is about half the weight and size of a field coil motor having the same cranking performance. The drive housing encloses the shift lever, the shift lever mechanism, and the solenoid plunger to protect them from exposure to dirt, icing conditions, and splash.
