LARGE tap and die source?

[Magnum440d100]

Working on this axle, and the threads are boogered up.

Where can I get large tap and dies?

Axle replacement is not an option. I’m resolved to cutting new threads and using a different nut. OD is 1” on non threaded part.

Thanks in advance!

For a die, I'd look on Ebay. Any chance of cleaning the threads up with a thread file or one of the other thread restoring tools? If you have to cut new threads, consider metric instead of fractional. Next closest fractional size is likely 7/8", while a metric size might be 24MM, closer to 1 inch. Good luck.

Edit to add if Ebay doesn't pan out, try Victor Machinery Exchange.

If you want to try a thread chaser die Snap-on has them individually, about 15$ each.

Complete set is about 80$

Matco has thread cutting dies, I had gotten a 14-2.00, IIRC, 20-25$ Run a search on tooltopia for the size you need, They may have it (Hanson brand).

You might be able to save it with a thread file. They are cheap and any gear head needs a set any way.

Find a machine shop and have them fix it.

I would, but that would require more disassembly and time. And I’m on a short time budget.


I forgot to mention that the nut for this side threads perfectly onto the other side. When tightened on this side, it snugs up and then loosens.

Thanks for the MM tip. Looks like that is what I may end up doing.

Thank you guys as well for the links!

Old trick, but it works. If you have a spare nut of the right size kicking around put it in the vise and cut 3-4 grooves in the inside of it with a hack saw. It gives you a one time use thread chaser. I’ve done it a few times before when I didn’t have a die the right size and it usually works.

Yo, I DO have a spare nut. Gonna try this in the AM!!!

THANK YOU!

Lang sells an axle re-thread kit but it's more for spindles on cars.

I've sourced most of my large dies from Amazon, incl 1.125x18 on 2nd Gen Ram D44s

It looks like the entire length of your threads are hurtin'. I encountered just the first few being the problem and simply removed them (something the factory later started doing)

A re-threading (or re-forming) die would be better. A regular die is just going to cut the squished threads right off; resulting in weaker threads. A re-forming die will push the squished threads back straight again.

 

[matt_i]

I'd fix the smashed part with a needle file that's a 3-square meaning equilateral cross section. You can take out the crests which are totally smashed flat. The other crests are a little rolled but depending on torque its worth another run at it.

McMaster Carr 4261A54, which is nice because one tool will fix any typical threadform, SAE or metric, they are all based on the 60 degree equilateral triangle.

You guys read the part where the nut threads on but won't tighten right? Sounds like the threads are beyond repairing, pretty unlikely any tool is going to "grow" the threads, at least not enough that I'd trust them.

I have a Matco set.

Virtually all brands of thread chaser taps and dies are made by Lang, formerly Kastar. SO was the only place I have seen selling open stock. They are sold as Bluepoint. If you are looking for a set, shop for price. There are sets in quite a few sizes, SAE,metric, big sets, small sets, etc. under several brand names. For cleaning up threads, a thread chaser is better than a cutting tap/die. It cleans away dirt and pushes bent thread back into line. I cutting tap/die shears away what is out of line, leaving a weaker thread. There are usually filings after using a cutting tap/die. BTW, SnapOn ships free to anybody with no minimum. For a small part or two it can be the cheapest route.

Yeah, seems like everyone missed that. Maybe stack some washers to get on good threads - or time for another axle.

 

[larry_g]

what is this on? Looks to be a lawn mower or kids toy. If so then other options are possible. Figure out the real thread size and pitch. If you can and it a not critical application threading on a shaft collar and tightening it down may work.

I might file it up some, remove any burs. Take the spare nut, put some never seize on it, work it on as a reformer, run it on a ways and tap on it with hammer some, btw, most auto parts stores have some or overnight.
But work it on some, tap flats some, work back and forth, remove any dross or filings that come loose. Never seize works good for this.

Got my IIRC 7/8" Die on e bay. Only about $10.00 IIRC!
I had Slightly buggered up the shaft for my vintage Powermatic 6" belt sander, when I was doing the bearings.
EDIT; Looking at the picture better, it looks like it would clean up nicely with a restorer.
Taps and dies tend to "hog" out metal, where it is not needed, when used to restore/repair a thread.

 

[BDT/NWMN]

Use a thread restore die and a get a NEW nut.. The male threads on the axle shaft are damaged.

The chance of the threads in that nut remaining totally undamaged are nill. Testing a damaged nut on the other axle shaft only proves the other axle is in better condition.

That worn out nut is evil and can spread diseases or undue wear when threaded onto other parts. Kindly toss it.

 

[bwringer]

Exactly what size/pitch are those threads, and if you re-thread, exactly what is your plan?

For example, are you planning on going to 24mm?

And yeah, a new nut plus a thread file or thread restorer might fix things up better than you'd think. Hard to tell from here.

 

[Ign]

As a last resort nuclear option see if there's a metric size just a touch smaller and run that die over it. Or the other way around if it's already metric.

Some metric and fractional thread pitches are VERY close - although others are miles (or kilometers I suppose) apart.

 

[The Cobbler]

maybe even a longer nut so it grabs more threads to get you by.

 

[bluebolt]

It would help to know what the application was. Fix the threads as best as possible and use a thicker nut or double nut it.

Sorry for the late response guys.

Thread is 1” x 14 it appears.

The application is a kids go kart. It’s for a friend of mine, and I want it fixed as correctly as possible if kids are going to be in it.

The threaded collar I linked above would work for that. Since the threads are compromised, peaks of the threads look to be gone, I'd suggest you chase the threads and then install the threaded collar and clamp it on tight. The clamping action will lock the collar to the compromised threads.

Got the Lang set today. Awesome quality AND made in USA. Couldn’t be happier.

Just one issue haha

So the 1-14 cleaned up the passenger side (the side that works great) but is super loose still on the drivers side.

Well, alrighty then........

Clean threads and nut with brake cleaners. JB Weld on the threads when you install the drivers side nut. Very low final torque. Wait at least 24 hours at temp >50F.

This will hold ... for awhile. Use heat to get the nut off. Next time, disassemble and take it to a machine shop.

OR

A whole new axle is under $60 if the length is less than 48".

 

[El_Guapo]

For a quick and dirty "repair", cross drill it, load the threads with Loctite 660 and put a cotter pin to hold the nut in place.

I know it's a little late but would something from here have worked?
