    FXE cast rear wheel

    I have a 74" FXE I think the motor is 77, tranny is a 79 (rotary top), it's a build bike from a wreck 20 plus years ago. It has a 9 spoke rear cast 16", dished sprocket and counterbored 3/8 bolt rotor. Trying to find a  replacement rotor, rotors are listed 73-78 and 79-82 for FX. Not certain of the difference and not sure what year the ass end is. Need an expert or somebody from OOT.

    Re: FXE cast rear wheel

    jj - first, welcome to the forums - what part of the country are you from?

    You will probably have to contact customer service (button above).  They will probably want to know:
    - the outside diameter of the rotor
    - the diameter of the inside of the rotor
    - the thickness of the rotor at the inside
    - the center-2-center distance between the #1 and #3 bolt holes (#1 top, clockwise to #3)

    Hope this helps

    The first tool out of the box should be the "book"  Geeked

    Re: FXE cast rear wheel

    It's a stock cast wheel 40987-74, I'm wondering if the alignment changed with the late 78 rotary tyranny vs the ratchet top. It's a 1p in rotor, stock 5 bolt hub pattern. I've seen some rotors with a slight offset. Don't know if proper rotor is on it but it's shimmer and fits well.

    Hate spell check, 10 inch rotor. No part # on rotor, I guess I can just shim it out if need be. Anybody have a tip on swimming a banana caliper?

    You may not have to shim the caliper, they 'float'. Mock it up and see what ya got...

    Don't force it, get a bigger hammer.

    I was referring to the different size spacers for the rotors.

    Re: FXE cast rear wheel

    What I meant was that since the caliper floats, you may not have to adjust the shims on the rotor to match up with it. Put it together and see what you have.

    Re: FXE cast rear wheel

    I will give it a go, the chain drive square swingarm ass ends are all pretty much the same, it's always suttle differences when models change. Thanks for your advice. I have never had to shim a rotor in the past, the one I have now has a shim on it.
