Yanmar 129491-42560 Shaft Assembly

The Yanmar 129491-42560 is the genuine replacement shaft assembly for Yanmar marine diesel sea water pumps that use this part. It is the backbone of the pump and the part every seal in it depends on.

Fit it with new seals, and check the bearing at the same time. A shaft that has worn unevenly usually has a bearing behind it that allowed the movement in the first place.

Frequently Asked Questions

Q: Should I replace the bearing at the same time?
Check it. A shaft that has worn unevenly usually did so because the bearing allowed movement, and fitting a new shaft into a tired bearing repeats the wear.

Q: Why does the shaft corrode?
Salt water that has been past a failed seal sits against it. That is why a weeping seal is worth dealing with early rather than at the next service.

Q: Does the impeller drive matter?
Very much. A worn keyway or drive flat lets the impeller move on the shaft, which wears the vanes unevenly and eventually rounds off the drive altogether.

Q: Do I need special tools?
A press or a suitable puller makes the job straightforward. Driving a shaft in or out with hammer blows damages the bearing and the seal bores.
