    Seal surface fix for aluminum hub.

    Picked up a lone star axle. The seal surface on the sprocket hub was grooved. So decided to see if I could fix it. This is what I started with.

    This is the speedi sleeve from Napa I used.

    This is the end result.


    The sleeve has a flange on it for install. Had to remove the flange to get it on the last little bit. Hope this might help someone.

    Just figured I would give it a shot. I did not want to take it to a lathe. Just an option for people.

    Third option would be build it up with weld and re turn the piece as well.

    Only problem with that is you are still using the soft aluminum for sealing surface
