M101A2 wheel studs

[McGuyver]

I have a couple of studs that need to be replaced on my M101A2 axle. The technical manual TM 9-2330-202-14&P calls this out:

ITEM SMR CODE NSN CAGEC PART NUMBER DESCRIPTION QTY
10 PAOZZ 5306012376844 19207 12354223 BOLT,RIBBED SHOULDE................. 8

UOC:CT1,SPR,TC1,258,263

I have new studs with "19207 12354223" marked on the head, they are the ribbed style with a shoulder, just as the description calls out. However, they don't match what's currently on the axle. The axle has dual threaded studs with 5/8-11 X 13/16" L threads on the hub end, and 9/16-18 X 1.25"L threads on the wheel side. Anybody know what's going on? Do I have an older style configuration that isn't in the TM anymore? Anybody know what the part number is for the dual threaded studs that I currently have, or where I can source them?

Thanks in advance.

On the left is the part number out of the TM. On the right is one of the studs from the axle:

Post pictures directly to thread if you would.
That link will go dead at some point and not help anyone.

Sorry, apparently that's the way Tapatalk does it from my phone.

The one on the left in the pic are what both my M101A2's have.

Never seen a threaded wheel stud like that before on a M101A2 trailer

Worse case is to replace the hub.

I guess I must have an older style A2 axle?

I stud on the left was missing from an A2 I worked on. Was not able to locate one....If you decided you want to sell them, let me know. Good luck with your search.

Not sure what I'm going to do yet, but I'll keep you in mind.

wow i hope you can find the correct ones. i didnt know those new ones dont fit

 

[McGuyver]

Not a problem. I found a local source that would work, they're just not an exact match (a little longer OAL, and longer unthreaded section). I'd still like to find a closer match if I can, but what I have right now will work.
Like I said before, the studs you gave me have the correct numbers on the head that match the TM. This axle just must be an older version before those were used. I could retrofit the hubs to use them if I wanted to.

Does anyone know of a source for the press in wheel studs?
I recently acquired an M101a2 that is missing two studs and I haven't had any luck searching.

Pop an old one out.
What is the stamping on the head? Usually letters/numbers.
Axles are dexter. Studs are common at a trailer parts place like e trailer/croft or old school real parts store like Napa.

Earlier reference to a double threaded stud was some odd ball hub or most likely a Bubba engineered repair. Wheel Studs are pressed in for a safety reason so they can not spin out.

... most likely a Bubba engineered repair

That !!

No such thing. And if there was, the UOC, Usable On Code would tell you that. It would list both studs and give you the right info.

I am still looking

On what? The bus? Be a little bit more specific.

My studs are marked with the letters D B M.
I've searched Croft, Etrailer and several other online trailer stores. Everything has a larger diameter splined section.
I'll take one to the main Napa warehouse here to see if I have any luck.
