Yanmar 128170-42060 Impeller Shaft for 1GM and 1GM10

The Yanmar 128170-42060 is the genuine replacement impeller shaft for 1GM and 1GM10 engines. It is the backbone of the pump and the part every seal in it depends on.

Corrosion is the marine version of the same problem. Salt water that has been past a failed seal pits the shaft along its length, and a pitted shaft destroys new seals as fast as they are fitted. The keyway or drive flats are the third area to check, because a worn drive lets the impeller move on the shaft and that movement shows up as uneven vane wear.

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.
