This OEM replacement part is a starter motor for generators. The starter motor spins the flywheel to start the generator when the power is turned on. If the generator is no longer turning on, then it might be time to replace the starter motor. Luckily, replacing a starter motor is a fairly simple repair. Before beginning, make sure the generator is turned off. Once powered off, remove the cover of the generator to gain access to the starter motor. Once located, remove the mounting bolts that attach the starter motor to the generator. After that, replace with the new starter motor and fasten the bolts to hold it in its proper position.This genuine replacement part is sold individually and is compatible with Generac generators.
