Installation Notes
- Disconnect the negative battery terminal and shut off the fuel supply for safety.
- Close the seawater inlet seacock to prevent water from entering the vessel.

- Loosen the hose clamps and detach the inlet and outlet hoses from the pump. Be prepared for some residual water to spill.
- Unbolt the seawater pump from its mounting bracket on the engine.
- With the pump removed, the old drive sleeve will be accessible. Pull it off the pump shaft or engine connection point.
- Inspect the shafts for any wear or corrosion before installing the new sleeve.
- Align the splines and slide the new drive sleeve into position until it is fully seated.
- Reinstall the seawater pump, tighten the mounting bolts, and reconnect the hoses securely.

Troubleshooting & FAQ
How do I know if this drive sleeve fits my generator?
This part is compatible with a range of Kohler generators, including the 4EF, 5E, 6EF, and 7.3E series. The most reliable method is to match your existing part number to the direct replacement number: Kohler 359448. Always verify using the compatibility table provided.
What are the signs of a failing drive sleeve?
A common sign of a worn or failed drive sleeve is an overheating generator. The sleeve's splines can strip, causing the seawater pump to stop turning. You may also hear a grinding or whining noise from the pump area, which indicates the connection is slipping.
What is the function of this part?
The drive sleeve acts as a coupler, transferring rotational power from the generator's engine to the seawater pump's shaft. This action drives the pump's impeller, circulating raw water to cool the engine.
Can I replace the drive sleeve myself?
Yes, replacement is a common maintenance task for individuals with basic mechanical skills. It involves removing the seawater pump to access and swap the sleeve. However, if you are not comfortable performing this work, professional installation is recommended.
How often should the drive sleeve be replaced?
There is no fixed replacement interval. It is best practice to inspect the drive sleeve for wear, cracks, or stripped splines whenever servicing the seawater pump (e.g., during an impeller change). Replace it proactively if any signs of wear are visible to prevent unexpected failure.
Is this part identical to the original Kohler 359448?
