Title: MCI 102A3 stud sizes / dimensions (steel or aluminum)
Post by: daveola on 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?

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.

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     
Title: Re: MCI 102A3 stud sizes / dimensions (steel or aluminum)
Post by: chessie4905 on 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.

Funny because my father in law actually makes these studs for meritor. He can look at the stamp on the end and know it came from his plant here in Michigan. Crazy but true. He'd do a run of them for us if we needed a larger order.

Crikey - are they so expensive because most they are an unusual size?  Aren't most truck studs something like $7-10?

Because even if I don't replace the drive studs (since they fit, though I would be happier if they were replaced) that's still close to $800 for just the studs, then at least 4 hours of mechanics work to pull the hubs.

Yeesh.

Are the original studs for steel around the same price?  Because partly I want the aluminum wheels, but partly I just need to replace the studs on my bus.

if they don't have a press you're in the wrong place.

Post by: lostagain on April 23, 2018, 05:44:31 AM
You don't need a press to remove those studs. There is a space between brake shoes at about 9 o'clock. You turn the hub so the stud you want to remove is there. Spin the nut off the back of the stud. Place a big oversize nut (spacer) over the shaft, replace and tighten the nut to pull the stud off from the back. A little help with a hammer on the front of the stud helps to get it started. That's how I do mine.

That's ridiculous. a total replacement of studs on a coach with a tag would be over 1600 bucks? I used to use the example of replacing tires on a bus was not 500 bucks but 4000. Now I got a better one, replace wheel studs is $1600 ATM visit. lol

take one off and measure it.

Here is the Euclid number you can get the dimensions from their site E-5922-L and E-5922-R or the Meritor number is ROO5922- R or L maybe Dorman makes the studs also

That should be correct number but Find it Truck Parts sold me some for $6.40 ea for 10 in box with that number that were not correct they were for steel wheels 1-3/4 long so watch Find it Parts.The only difference is the std steel wheel stud is 1-3/4 on the wheel end (1-1/8th)and the longer studs are 2 inches on the 1-1/8th end lol I chased these things for months and still have 20 of the short 1-3/4 studs for 64 bucks for a box of 10 they were worth keeping

I'm confused - in the Euclid catalog, it shows it as 1-1/8", not 1-3/4"

And you're saying that these parts (E-5922-L/R) are for steel, and I need something with a longer wheel end?  But is that 2" then, or 1-3/8", which is 1/4" longer?

The 1-1/8 th is the nut size 2in is the thread length , also check out BWP-NSI numbers M-2444 and M-2449 or better call them @ 636-629-5800 they have them but you need to buy from a dealer I found the BWP_NSI after I bought mine

I called BWP-NSI and the full length on those is only 3 5/8"?   Are the BWP parts for steel and the 4" is for aluminum?  I still haven't figured out what the aluminum length is.

Okay!  I just found a good source for the Euclid parts, but according to Cliff, the Euclid part number is for the steel wheels.  So I called Euclid, and they don't carry anything like the E-5922-L/R but with longer wheel threads, so now I'm back out of luck.

Does anyone have an industry part number for the studs for aluminums?

Mohawk was over $20.  If it's 4", then I think I've found them.  Should be more clear tomorrow after another round of calls.

MCI claims it's 4.25" for the aluminum, unfortunately, and the steel studs are now actually 4" according to their new part numbers.

E-5922 Euclid or 20x 1868 Mertior is supposed to be the right stud,when I got mine they were to short could be they sent the wrong ones too anyways I gave up and called Luke,you can buy the E-5922 or the 20x1868 Mertior for 6 to 8 bucks all over the net ,the ones I got from Luke are 4-1/4 long FWIW,I really don't believe a 1/4 of a inch could make any difference with nuts on both sides that only a 1/8th of inch on each side

I don't quite get it, you don't think 1/4" makes a difference, but you're saying that the ones you got were too short.  Do you still have them?  Do you know how long the wheel threads were?
