    So you had to replace the lower bushing and not the upper (flywheel side) bushing?

    I replaced both because they did show signs of wear. I had the whole engine torn down so it was just as easy to do both at the same time. They are both the same size and part number. Each bushing was less then $10. With a little effort I was able to save myself the cost of a new engine.

    Fyi those bushings fail or wear do to undersized oil journals, and under sized gerotor gear in oil pump. So if u did not solve both theses issues when u replaced bushings u will see this problem again in the fufture. Kawasaki knows of this problem and has solved it with larger journals and bigger gear.

    The more I think about this, the less confident I am that a simple bushing replacement will be anything other than a temporary fix. If the production clearances only managed to last 380 hours, I sure wouldn't expect that many from a new bushing on a crank that's already been wobbling about, potentially screwing up everything from the crank to the rods.

    I have a fh680v-aso1 kawaski 23 hp motor that the top end bushing went out. The crankshaft doesn't have any scaring so i would do fine with a new bushing and i figure i might as well replace the 2 bushings in the bottom end while im at it. Does anyone know where i can find them.

    Thanks Hunter

    Thanks. but what about the bushings for the bottem. they are not the same size and no matter where i look the bushings are not shown in the parts list or in the diagrams.

    Hey Y'all, what timing, can't believe this is coming up again, doing an engine in the garage right now & was looking all over for the P#'s. Doesn't seem like it was 2008 since we talked about this. Anyway, couldn't find the #'s and an e-mail comes in my box, (I do believe in ghosts, I do believe in ghosts). If the numbers are the same for both bushings, great, if different I'll stay in touch, got away from Lawnsite for awhile, (got too smart) that was a big mistake. Thanks All
