Generac A0000501971 is now the new replacement for the Generac 0E9323 & 10000001020 starter motor, which are no longer available. If you ordered the 0E9323 or 10000001020 starter, this will be the starter that's shipped in its place. See the second image for the comparison between the two style starters. Both styles are currently being used by Generac and function the same.
0E9323 Gear Reduced 1kW starter motor fits many different size Air Cooled standby generators. Started being used around 2005-2006 and is the current standard starter in units 10kW and above. Commonly a cause for 15A system fuses blowing on the control panel. If your current starter doesn't look like this, it's most likely NOT the correct replacement for it. Was used on a few 15kW and 12kW 4390-3 and 4456-3 models towards the end of the product line for the transition into the 5200 Series.
Generac made a change to the nose cone on this starter where the starter mounts to the engine block. In some applications this can cause interference with the heat shielding on the blower housing. The starter's nose cone can either be swapped from the old starter if it good condition, or the heat shielding can be tweaked out of the way to make the starter fit correctly. This issue does not affect all models.
This is an OEM Generac replacement starter and not an aftermarket version like found on Amazon and eBay.
Generac replacement parts will also usually fit the following Generac branded generators: Honeywell, Guardian, Siemens, Carrier, Watchdog, Centurion, & Bryant.
