Yanmar 119578-42720 Cam Screw for 6LY3

The Yanmar 119578-42720 is the genuine replacement cam screw for 6LY3 Series engines.

Substituting hardware store items is a poor idea here. The wrong material sets up corrosion between dissimilar metals, the wrong length bottoms out before it clamps, and the wrong grade stretches. Keep a few spares with the impeller kit and the problem does not arise.

Frequently Asked Questions

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.

Q: Can I use a stainless fastener from the hardware store?
It is a gamble. Material, grade and length are all chosen for the joint, and the wrong material in a dissimilar metal housing sets up corrosion that seizes the thread.

Q: Mine is seized. Any advice before I break it?
Heat, penetrating oil and patience, and a properly fitting driver rather than an approximate one. Once the head rounds off the job gets considerably harder.

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.
