GENERAL DESCRIPTION OF STARTER

The Electrical Engine Starter is a heavy--duty, 24--volt DC cranking motor for large diesel engines. It is insulated and

waterproof, and is resistant to both fungus and corrosion. Its output drive pinion is moved into mesh with an engine

starter drive gear by a solenoid operated, enclosed shift lever. The starter motor output torque is applied to the drive

pinion through a heavy--duty overrunning clutch which prevents an engine from back--driving motor armature. Pinion

end clearance is adjustable.
