Starter Motor for Generac GN191 GN220 GN320 GN360 GN410 - 12V 10T CCW
Replaces Generac 0D9004A, 0D9004B, 0E0601 and Arrowhead SAB0152 - 12V, 10-tooth, CCW
This 12V starter motor is built to OEM specifications for Generac GN191, GN220, GN320, GN360 and GN410 engines, fitted with a 10-tooth drive gear for correct flywheel ring gear engagement. Getting the tooth count right matters - a starter with the wrong tooth count either will not mesh with the flywheel or will engage roughly, so this unit is matched to the original 10-tooth specification.
It turns counter-clockwise (CCW) to match the original equipment rotation, making it a direct swap for a worn or failed original starter with no modification required to the mounting bracket or wiring loom. The gear outside diameter is 32.1mm (1.264 inch) and the field case measures 100mm (3.94 inch) long, with two 18mm unthreaded mounting holes and one threaded M8x1.25 hole, all matching the factory unit. This part is supplied ready to bolt straight onto the engine using your existing hardware.

Frequently Asked Questions
Will this fit without modification?
Yes, this is a direct replacement for the original starter motor on compatible Generac engines - mounting points, drive gear and wiring connections match the factory part, so no cutting, drilling or rewiring is needed.
What's included?
One 12V, 10-tooth starter motor, ready to fit. Mounting bolts and wiring are reused from your original unit.
How do I know my old starter has failed?
Common signs include a single clicking noise with no engine turnover, a slow or labouring crank that gets weaker as the battery drains, unusual grinding when the key is turned, or no response at all when starting.
Why does tooth count matter?
The drive gear tooth count must match your flywheel ring gear for the starter to engage correctly - always confirm the tooth count and rotation against your original part before ordering.
My Generac part number ends in SRV - is that the same part?
Yes. Generac service numbers such as 0E06010SRV, 0E0601ASRV, 0E0601SRV and 0F0610SRV all refer to this same starter and are covered by this unit.
