Yanmar X0146146-01 Cam
The Yanmar X0146146-01 is the genuine cam for Yanmar marine diesel sea water pumps that use this part. It is the raised block inside the pump body that the impeller vanes are forced to bend around, and that bending is what creates the suction and the discharge - without the cam, the impeller simply spins and moves nothing.
Inspect the cam whenever the impeller is changed. Run a fingernail across the face: any ridge or step you can feel is enough to cost flow, and it will chew the new impeller as well.

Frequently Asked Questions
Q: How do I know the cam is worn?
Look and feel across the face the vanes run on. A serviceable cam is smooth and continuous; a groove, a step or corrosion pitting means the vanes cannot seal against it.
Q: A new impeller did not restore my flow. Why?
The cam and the wear plate are the usual answers. Both form sealing surfaces for the impeller, and a worn one lets water slip back instead of being carried to the outlet.
Q: What happens if the cam screw comes loose?
The cam shifts in the body and the impeller runs into it, which usually destroys the impeller and can damage the body. Check the screw is tight whenever the cover is off.
Q: Is the cam handed?
Yes, it has one correct position and orientation in the body. Note how the old one sits before removing it, because a cam fitted the wrong way round stops the pump working entirely.
