Problem with installing a rear drum wheel

[Goose9696]

I have this old chopper frame and I'm having trouble putting on the rear wheel the problem, the pivot stud doesn't give enough clearance.

Here is the inside of the rear frame

It's hard to tell by the close up pics..... But are you sure that wheel fits that frame?????? It looks wrong for some reason.........

On the earlier XL brake that uses the spacer in your pic, the swingarm has a wide slot in which that spacer floats, providing the anchor for the backing plate.

Now, here is the crux of your problem:

The later XL swingarm had a narrower slot through which a bolt was installed into the brake shoe anchor inside the backing plate. That set-up is the type your frame is replicating. This requires careful shimming between the inside of the axle plate and the backing plate so that the brake works properly without binding. You may discard the spacer in your pic, add enough spacer between the frame and brake, and add a washer and nut on the outside of the axle plate. If the stud is not long enough to accomplish this, you can swap in a late brake shoe anchor, which has a threaded hole instead of a stud.
OR, you can make the slot in the axle plate wide enough for your spacer to float (and you may have to add material to the inside of the axle plate to give the spacer sufficient purchase).

Look at the repair manuals for early and late XL brake set-ups, there are pictures of each that should make things clear.

Thank you for the info Jim gonna try with the axle plate to make it wider What would be the best way to do that process ?

It needs to be a slip fit on the spacer in your hand in the first pic. Scribe the lines, and use a die grinder to widen the slot, and file to the final size. You will probably have to add material on the inside of that axle plate so that spacer will have a wide area to bear against. Some 1/4 or 3/8 square stock or key stock would probably do it. Weld securely and finish size with a file.

The alternative of swapping a later brake shoe anchor into the backing plate would be easier.

hey Jim thanks for the info sorry for the late reply had to replace my phone going to see about brake shoe swap

Shot almost forgot to ask any leads where I can find the right size brake shoe anchor ? Or making the right choice on buying it

Probably easiest to find a complete, later backing plate assembly. Should be reasonable in cost.

The brake shoe anchor will have a female thread, instead of the stud yours has.
