Yanmar 119578-42540 End Cover for 6LY3

The Yanmar 119578-42540 is the genuine replacement end cover for 6LY3 Series engines. It is a simple part whose flatness has a direct effect on how much water the pump can move.

Whenever the cover comes off, renew its seal and tighten the screws evenly in a cross pattern rather than working round the circle. That single habit is what keeps a cover flat for years, and it costs nothing.

Frequently Asked Questions

Q: Does the cover affect how much water the pump moves?
Directly. It is one of the two faces the impeller vanes seal against, so a pitted or bowed cover lets water slip back inside the pump instead of leaving the discharge.

Q: How do I tell if the cover is distorted?
Lay it on something known to be flat and look for daylight under the edges, particularly between the screw holes. A bowed cover will not seal and will not present a flat face to the impeller.

Q: My pump draws air rather than water. Could the cover be the cause?
It is one of the first places to look, along with the cover seal and the intake hose. Air drawn in at the cover joint gives a weak exhaust stream with a perfectly clear strainer.

Q: How tight should the cover screws be?
Snug and even, in a cross pattern. Overtightening is what bows the cover in the first place, and a bowed cover leaks however hard it is done up.
