Model T Ford Forum: Forum 2016: Is there a tap and die so to speak for the hub cap?

I think the hub is original but the new repo caps do not screw on two of the hubs. Any suggestions?

If it matters, it is a brass hub cap.

I tried switching one cap to the other hub and it did not work. Still not sure if it is the hub or the cap or the union of the two.

I think the threads are stripped one of the hubs......

Robert..Snyders has a thread chaser for the hubs, a bit expensive. Part # T-2815-T.

Check your hubs, if any of the threads on the hubs look flat you may need to dress them with a small triangle file or a thread file to make the new hub caps fit.

A thread file is my first choice - can be used everywhere and is relatively cheap.

Maybe a rear wheel puller also can act a little like a thread chaser if you can get it on the hub thread, clamp it as tight as it can be while still being able to unscrew it?

I've had some success with taking some steel wool or a nylon scrungy thing and wiping the outer threads of the hub and the inner threads of the cap.
If there is any crud, rust, dry paint, old grease, etc., it might be enough to cause a jump in the threading.
Make sure both male and female threads are clean, maybe touch them up with a file and see what you get.
I've also taken a small finishing nail and started it on the threads and try to run it around by hand and see where it jumps off.

Good luck.

I think there is currently one for auction on Ebay. I saw it very recently. Probably cheaper than a new one.

If you're very lucky and have the dough, you may get one of these. But I've been looking for years with no luck.

There's a modern version that comes with cutters for a variety of threads, also not cheap.


Another choice is the thread file. Much less costly but more work.

I bought the hub cap chaser from Snyder's. I had to use a small triangle file on the first 5 threads to get the chaser to start. The brass cap screwed on, but it was tight.

If you are a bit creative? You can build your own.





I was in a rush, and did a sloppy job. But what I did was cut/fracture a die of appropriate thread. Braze the pieces to a shaped piece of strap steel, and stiffen it welded to pieces of round stock.
Ugly, but it works nice.
I have toyed with the idea of making something similar for the inside of the hubcaps, but find I rarely needed one. The simpler thing to do if you do need one for a hubcap, is find a cracked hub. Then cut a few cross cuts through the hub's threads with a common hacksaw. That should be able to clean up most hubcaps if they are marginal.
Drive carefully, and enjoy, W2
