    Sripped impeller splines - now what?

    I have a 2008 Kawasaki Ultra LX.
    I pulled out the jet pump today, and found that the splines inside the impeller were completely stripped.
    That explains why the drive shaft was spinning, but I wasn't going anywhere.

    Now, how do I get the impeller off the pump shaft??
    I can't just use the impeller removal tool, because there are no splines.
    Do I jamb something between the impeller and pump body and use a wrench on the pump shaft?
    Does the dealer have a "special tool" for this?

    Can the splines be repaired or do I need to buy a new impeller?
    Thanks for any help.

    I would put the end of the pump in a vise, put some heat on the prop, then maybe try to tap it off using a piece of wood and hammer? Wouldn't worry too much about the prop as you'll be throwing a new one in there anyway.
    Don't wedge anything against the stator veins, you could blow one out costing you more cash.

    Do a full inspection of the pump whilst it's out. know what caused the splines to strip in the first place?

    if the vise , heat and hammering don't work You're gonna have it cut that prop off with a small dremel metal cutter, like mentioned earlier the props no good anyway,carefully right over where the threads are and try some propane heat around the prop threads to expand the metal ever so slightly,then the hold in a vise and hammer again...

    good luck

    Man you guys make shit hard....

    A Simple pipe wrench will undo the prop while u hold the flats on the shaft in the vise...

    No cutting, no heat, no dremels or grinders

    Just 2 minutes and whammo easy

    +1 on the Pipe wrench. Those things are one of the handiest tools around.

    This is all I can find on my tablet, too hard to find, heres a some pics, remember we arent using the wrench like it was designed more like a lever. Top jaw down inside splines adjustable jaw against top blade.

    So did you get it off, or kill yourself doing it since you havent been back?
