My HD Hub center threaded axle shaft sticks way out on one side, too short other side

    My problem is that there isn't enough thread length sticking out on the pedal/chain side of the rear wheel. Please see photos.

    It seems like it's sticking out really far on the drive chain side, and only a little bit on the pedal chain side. Is there a way I can scoot that sucker over WITHOUT tearing apart the whole hub. I'm nervous to do that again there are so many parts in there and I do not have all the right tools.

    Please see photos posted on google photo album:

    Yes I did take off the drum brake, it's all tore up I'm not planning on using it with my new build. I've got a nice new mountain bike to work with and I'm getting some custom welding done to get the engine mount welded in place. I'm going to use the caliper brakes, that drum brake was a piece of chinese garbage I think. But I like the freewheel HD sprocket so the investment was worth it so I'm not bolting on to spokes anymore....:cool:

    Any help/suggestions?
    Thanks

    Hi Bill
    I am not known here are as a force in the MB world here but here you go. If you do not have any clearance problems with your chains on either side and it fits your frame with out stretching out to far. HD axle kit when it is together should be 5 inches wide max you may get it a tiny bit more than that but if your not using the brake you should be way less than 5 inches. The biggest thing is the chain clearances on each side and you can use the sprocket dished in or out what ever suites the wheel better. Now install the wheel with out the fender then check to see if your wheel is centered if not you can take it to a bike shop and have them center it better. I did look at your pictures it is hard to see if there are any issues from them or from what I can see they look OK. It is all about clearances.
    I hope this helps you

    Well....all I'm asking is, I need more length on the side where the pedal sprokets are. When I go to put the wheel on, the axle (threaded rod) doesn't stick out far enough to put a good nut on.

    After it's sitting in the frame it's only got 1/2 an inch of threads to work with. I can fix that stripped threads, I'm not worried about that, but how do I get more length on this side???

    OK so put some washers there until it clears the cassette you only need a small amount of clearance

    You can take away the ones on the brake side to make more room

    I am excited to see a multi speed cassette on there
    Good luck

    I need it to stick out a little farther.

    Well for starters you cant use a cassette on the HD hub.
    Second, If you need to adjust the side to side thread length all you do is back off the long sides nut away from the bearing and suck the short side over.

    As long as you can find a cassette that threads on the same way you can

    Flip the axle.

    You are going to have to flip the axle over to get the spacing that you want and then re dish the wheel. The axle has shoulders that act as the stops for the cartridge bearings, so you can't just loosen the lock nuts and slide it over. The hub from Grubee is spaced for a single speed freewheel on the pedal side, not a multi speed freewheel. I believe that member Alaskavan did a really nice thread/review of this hub showing with photos the steps necessary to flip the axle. I remember that it was a really very simple process. You might do a search for this thread.

    Flipping the axle is very easy and thanks good to know

    Ok stupid question, but I if I understand the terminology right, what I have done is used a cassette on an HD hub. And Biketek says that can't be done.

    So I'm doing it wrong. That actually makes some sense because what I'm doing isn't working out very well.

    What should I do, in order so that I'm not doing it wrong?

    I'm sure anything is possible, But its not designed to fit a cassette. The width is already almost too much for a bike, Hence the frame spreader.

    I really don't care whether I have multiple speeds to shift through. Does that simplify things any?

    I will look for Alaskavan's post.

    All you need to do to make it fit right is get a single speed CW 35x1 freewheel and adjust the threaded axle as needed. Keep in mind that they are offset at the factory to accommodate the brake.

    Cool.

    Please point me in a direction that leads to [a single speed CW 35x1 freewheel and adjust the threaded axle as needed]
