MCI 102A3 stud sizes / dimensions (steel or aluminum)

daveola · April 19, 2018, 11:59:59 AM

I'm switching out my MCI 102A3 to aluminum for all the outer wheels (keeping the steel on the inside drive) and I'm having a heck of a time finding replacements.

The shop says they need to pull the wheels to get a sample stud, but that leaves us off the road for a few days or more, depending.

I've got the MCI part numbers for the studs for steel wheels, but when I take them to a parts shop they can't lookup any of the specs (in order to figure out what studs I need for the aluminums), does anyone know where I can find these spec? (Or, even better, the part numbers for the aluminum studs?)

I have:

Front: 15C-2-35, 15C-2-36
Drive: 15J-3-18, 15J-3-5
Or? 15J-3-35, 15J-3-38
Tag: 15R-2-11, 15R-2-12

Just call Luke he has those n stock I never could find the Mertior studs on the internet,set down before pricing those, it will give you a heart attack at almost 200 bucks a wheel from Luke,MCI quoted me $38.00 per stud FWIW

Are you talking about US Coach? Because he's currently out of stock.

Call Mohawk. They have them and will know the sizes. They were the most reasonably priced last year when I was looking.

Whomever I talked to at Mohawk couldn't find the number and is calling back Monday. The price they quoted was $21.25 for the steer, as opposed to $19.03 at US Coach.

I can't help but think that if I could find the dimensions on either the steel *or* the aluminum studs I could figure out what studs to order from a truck parts shop and save a heck of a lot of money. Does anyone have some studs lying around?

And US Coach claims the steer and tag are the same stud, though the MCI Parts catalog gives them different part numbers, is that just MCI being ridiculous?

The steers and the tag are the same studs at least on my DL3 they were

Call C&J Bus Repair (cjbusrepair.com). They may well have them in stock.

Here is the Metior numbers for the standard stud
20-305 for the left
20-306 for the right, that is the size and length

Here is Prevost parts number which are the same as MCI for the longer studs but they were not any cheaper

RH -610117
LH--610116

If you peruse the pdf Euclid catalog in the wheel stud section, they list pictures of the studs and all dimensions. Maybe some interchange numbers also. BTW, all their studs are listed as grade 8.

What is Metior? Is that something I can lookup at a parts supply store? Or are you talking about Meritor as Dave5C posted?

Where is this pdf catalog (I didn't see a link in Dave5Cs post)?

I've seen a few PDF catalogs online showing plenty of studs, but how do I find the ones that fit an MCI102A3?

This just seems to be a page talking about Meritor as a company, I can't see anywhere to reference the studs or figure out which ones I have or need.

I use Euclid wheel and stud catalog. Google that and look for the pdf. I can't copy and paste a pdf address. Use the dimensions in the catalog to compare with what you have.

If you find them for a good price you will have been the first.

Many have trod the path you are on...

Squeeze your cheeks it's going to hurt...

Vaseline won't help.

Meritor is the manufacture ,Euclid is part of Meritor you can buy those direct from Meritor but they are expensive,Luke was cheaper @ 19.00 a stud, fwiw your hubs and drive axle are Meritor hope you find some at buy I never could

chessie4905 · April 22, 2018, 05:56:34 PM

Not suggesting to buy from Euclid, but each stud/ nut has 2,3,4, industry part numbers. You can then go from there. After the fiasco several years ago with cheap imported wheel fastener failures, the Feds stepped in and required certification and a proper paper trail and mfg markings on each part. Thats why they are so expensive now. At least you will be getting quality parts now.
