    Jb weld or some other epoxy for 650sx pump wear ring

    Anyone ever tried this. Skim coat the inside of the pump with epoxy. Then turn it down to the correct clearance on a lathe.

    Ive never seen it, but as strong as jb weld is I doubt it would hold up. You can see, even though aluminum is soft, jb weld is much softer.

    I am not sure you understand what I mean. Sea doo uses a plastic wear ring. Although I am aware some plastics like delrin are extremely tough. I would be concerned with the adhesion when so thin. Maybe some other epoxy. In any event may be forced to try it some day. Just thinking out load.

    I didn’t mean to sound like it’s a bad idea, I doubt a pump produces that much pressure, I’m
    Sure if the surface was prepared properly, like cutting back to fresh metal on the lathe, so that a thicker application could be applied, and then cutting back that thicker application... and if I’m reading the data right I might have been wrong, the “hardness” is actually Close to aluminum. And you are right, I didn’t even think about the plastic ones that seadoo uses.

    Y'all know me, still the same O.G. but I been low-key
    hated on by most these &^$$@s with no cheese, no deals and no G's, no wheels and no keys, no boats, no snowmobiles, and no skis, mad at me cause I can finally afford to provide my family with groceries

    Still don't see how it would be significantly different from a plastic wear ring. I wouldn't let a f#$%&$g clown like you near my lawn mower.
