Hard tail ironhead

[Cooldean69]

bought a project ironhead, I’m trying to set up the rear wheel and I think I have the spacers and stuff in there right and now it looks like I need some axle adjustment screws. It’s a 5/8” axle and the axle head and one washer/spacer is slotted to fit in the frame. My problem is if I put the axle adjuster/ chain adjuster things on I don’t think the slotted axle head will fit in the frame as it will be covered by the adjuster. Also each one is about 1/2” thick and I don’t think it will leave me enough threads at the end of the axle to screw the nut on. Thoughts? What am I doing wrong or right, do I just need a different axle?

On the drum brake XL swingarm, the adjusters go inside the axle plates. That allows the boss under head on the axle to fit the slot in the swingarm, and the stepped washer fits outside of the axle plate on the other side, with lock washer and nut over that. I can't speak for how your hardtail is set up, you will need to post more pictures.

And, the axle is not 5/8, it is metric, to fit the ball bearings in the hub.

The axle is slotted and fits into the frame

But doesn’t leave room to fit in frame eyehole slot thing if you add axle adjuster

I wedged the slotted nut between the drum and frame and that fits/seats pretty well also but if I put the adjusters on I think I’m gonna run out of thread

I’m guessing I need a different axle I’m just not sure why this one was on the bike or why it’s designed to fit the slot if I need to slip an adjuster over it

So you’re saying the axle is for a swing arm frame? Also the slotted washer goes outside of frame?

The additional pictures make your issue clear. You do not want to use the XL axle adjusters, you want big twin axle adjuster screws as found on rigid frames and round swingarms (which are fine thread) or Softails (which are coarse thread). The adjustment screw will bear against the head of the axle on one side, and on a collar over the axle on the nut side. Whether your axle is long enough to accommodate all that is up to you to determine. And the step washer should go on the outside of the axle plate, as I stated earlier.
