Yanmar 119578-42660 Ball Bearing for 6LY3

The Yanmar 119578-42660 is the genuine replacement ball bearing for 6LY3 Series engines. It is the part that quietly decides whether the rest of the pump has a long life.

The symptoms are a rumble or growl that changes with engine speed, and play if the shaft is rocked by hand with the impeller out. Any roughness you can feel turning the shaft is enough - a bearing that is notchy by hand is far worse under load.

Frequently Asked Questions

Q: Should I replace the seals with the bearing?
Yes, without exception. A new bearing behind the seal that killed the last one simply repeats the failure.

Q: Can I repack a rough bearing instead?
No. Once the races are corroded or brinelled, no amount of grease restores them. It is a replace item.

Q: How should it be pressed on?
Square, and pressing only on the race being fitted. Driving a bearing through its balls damages the races before it has turned a revolution.

Q: Does bearing condition affect pump output?
Indirectly but significantly. A worn bearing lets the shaft move, which changes the impeller clearances and loads the seals unevenly.
