    polaris jet pump siezed

    We have a 96 polaris slt 780 that sat in storage for year got flooded out in a hurican and a list of other mishaps. The engine starts after a long rebuild process but only without the jet pump assesmbly attached. Is it possible to put penetrating oil on the bearings and turn by hand to unsieze the bearing or pump shaft? Is it even possible to turn the shaft if I put a wrench/prybar on the back end?

    If the pump bearings are seized save the oil and replace the bearings and seals.

    He meant don't bother with the penetrating oil, no oil in the jet pump.

    Not sure if your pump is the same as my 1999 slx 1050 but I had the same problem and found that my wear ring swelled and jammed my impeller to the housing. I had to pry the housing off. Once I got it off the pump bearings spun fine.

    Mine had the same issue when I bought it the wear ring corroded behind it and pushed it out and that made the impeller seize. Just get a new(used) wear ring
