Troubleshooting & FAQ

Q: How can I confirm this drive sleeve will fit my Kohler generator?

A: This part is a direct replacement for Kohler 359448 and Sherwood G8001 and is specifically used in the GM28487 seawater pump. It is compatible with Kohler generator models in the 4EF, 5E, 6EF, and 7.3E series, including their CD and KD variants. Please review the detailed "Compatible Engine Models" table to verify your specific model is listed.

Q: What are the symptoms of a failing impeller drive sleeve?

A: The most common sign is generator overheating. A worn or stripped drive sleeve will fail to spin the impeller, leading to a loss of cooling water flow. You might also notice the impeller is stationary even when the generator's drive shaft is turning.

Q: Do I need to buy anything else for installation?

A: This drive sleeve is designed to be used with the Kohler Impeller Kit 359978. Since you are already accessing the drive sleeve within the pump, it is highly recommended to replace the impeller and pump gasket at the same time.
