Yanmar 119578-42570 Cover Screw for 6LY3

The Yanmar 119578-42570 is the genuine replacement cover screw for 6LY3 Series engines.

Use an anti-seize compound on the threads when reassembling, and tighten evenly across the joint rather than round it. That is what keeps a cover flat and a joint sealed.

Frequently Asked Questions

Q: Should I use anti-seize?
Yes, on the threads. It is what allows the joint to be opened again next season without a fight.

Q: How tight should cover screws be?
Snug and even in a cross pattern. Overtightening bows the cover, which is one of the most common causes of a pump drawing air.

Q: Is it worth replacing them all at once?
If several are corroded, yes. A mix of new and tired hardware clamps unevenly, and the old ones will need doing at the next service anyway.

Q: Why does the pump hardware corrode faster than the rest of the engine?
It is in the wettest place on the engine, often in contact with a dissimilar metal, and it gets washed with salt water every time the pump is opened.
