one of my front wheels the Hub cap will not start up on the hub. yeah the threads are screwed up some. 25 TT
Any tips?
Threads on the cap, or on the hub? Cap: get another one. Hub: local farm supply should have a thread file. Slow work, but it does the job.
I have one front hub where someone overtightened the bearing and split the hub just a little in the hub cap area. You couldn't even hardly see the split, but a new hubcap just wouldn't go on. The hubcap that was on that hub previously had a crack up the side where the threads are, because someone forced it on. The only solution for this is to replace the hub.

I had the same problem recently. Lang sells a thread chase. I put the chase in a vise facing up and carefully rotated the wheel on the chase. The weight of the wheel kept pressure on the chase and I was able the straighten the threads back to normal.
Or you could get a little rough! If just the first few threads are damaged, as they often are, just file/grind them off. The threads left will certainly be enough to hold the hubcap on. If this does not work, you are no further behind, as the next thing would be to replace the hub anyway.
May this help.

I bought a thread file years ago from an auto parts store for my TT, but, I've used it many times since. The fact that it does 8 different size threads make it handy.
One of these should help if you can find one in good shape. Stevens T-181. According to a forum post about three years ago they turn up at swap meets all the time, but I've never seen one.
I had trouble starting a replacement cap on the hub on the front of my TT last week.Turns out there was a raised area on the first thread.A soft hammer bump here and there got it back round and the cap went right on.I could feel the lump when I held my finger against the threads and turned the wheel.
I had M.S.C get me one made.
Herm, if you don't mind my asking, how much did they stick you for that monster?
Great Ideas yall,I might beable to find that die here at work.
The T 181 tool ive seen before,I will look for one at Hershey.

Checked the M.S.C. website, a stock 2 1/2" x 18 Re-Threading die, with 4 1/2" outer hex, lists @ $209.00/ea.
They have a email custom quote link on the page, so you could get a quote for such a re-thread die.
I bought this re-thread tool for hub caps from Lang's #2815T, lists for $69.
Like it somewhat, you do have to get the outer flatten-downed threads on a bad hub in good shape first before you start tapping. You have to get out that ole thread file to start. Then once the tool can fit on the hub, it does a fairly good job.
Most times those hub threads are pretty shot looking, but this tool can fix 'em. But take your time, long process.
Because it's usually the outer threads that are damaged, making it a chore to get a one-piece die started, I'd like to have a hinged device like the T-181 that can be applied where the threads are good, and turned outward.
Steve - I agree. I'd like very much to find a T-181 too. I've never seen one...they're probably as rare as hen's teeth. Oh well.

Steve, I have had it for 20 years, and used it many times, and I just don't remember, but at the time I think about 75.00 dollars.
I use it on all hubs, even if the hub caps seam to fit nice, and when done, they all work supper, and not want to cross thread.
Herm.
I should add, with this Die, any dinged threads on the out side, does not bother, as the Die taper lets you start into it right.
Now if the out side is smashed, then you have to prep it.
