    250es hub swap

    Will a 86 or 87 250es hub fit on my 85 differential and axle?

    Or will any other hub match with the 85 axle splines. My left hub is bent up pretty bad because of what I had to do to get it off of the axle.

    Heat+puller+=got it off

    What about the right side hub put on the left side? Would that work? I can find some right side hubs but the few left hubs are pricey. But I do need one.

    Totally different. You need the correct year and side to get fixed up

    What about the bearings are the same. I just ordered some for the 85 diff and axle tubes. If the parts bike isn't an 85 would the bearing that I ordered work or do I need to cancel the order?
