Well... as long as we are abusing Speednjay's thread I'll add this ...

Can we identify the brand of this item I just received? Supposedly from a closed MB shop. and should equal a 126 410 04 15. Says Germany, but looks like a grinder removed the brand symbol (see photos)

The reverse is un marked. ( see photos) Which side should go forward?

About the brand - the seller originally claimed FEBI ( so I bought it) but when I called him on that after having it in hand he admits he can't back that and doesn't know.

The other one I purchased elsewhere is supposed to be genuine MB. tracking says it is coming yesterday and is currently about 300 miles away in a different state. If history can be my guide it will take a while and a few more pit stops to get here ( 2nd day USPS PM from Nov 1 ) It is not easy being me

That PAT number leads to this : https://patentimages.storage.googleapis.com/98/b5/d1/1565f6afb7bc90/EP0781933B1.pdf Where it is claimed to be a design improvement? Perhaps I'll end up being a test mule ....

Why does it matter? Stamp says Germany and they have quality parts.

Inquiring minds want to know The PAT info links all over the universe but also seems to point at C.O.R.A. S.R.L. as the manufacturer. The seem to be a small outfit and has let this PAT expire for non payment of fees. They have what seems to be a simple website: https://corasrl.it/en/powertrain.html which is of no help Also, it has been proffered that there is a forward way to mount this, and if that is the case I'd like to know which way.

going by my old post on this thread, the side that used to have the brand would face the transmission. The photos aren't clear enough to make out surface texture of the rubber and the fibers. Seeing them would offer clues presumably (keep the fibers under tension, not compression). -cth

Is there a legal distinction between 'made in G' and just G?

Seems like you're putting a lot of effort into something as simple as figuring out how to mount a part when you can easily either go check under the car you're mounting it on to see which way it goes, if possible, or just Google images of rear flex disc orientation. Either way, several hours have already gone by and you don't seem any closer to the answer of your original question of mounting orientation.....unless you've now deviated from that and just want to know about the business affairs of some manufacturer . At any rate, the photo you posted appears to be the disc that can be mounted either way. On the discs that are unidirectional, the mounting holes are offset and the front of the disc is stamped to inform you of which way the disc should face.

You make one of my points. This one doesn't seem to require a particular orientation. Hence my surprise at the notion.

If I can't be comfortable with the manufacturer I'll send this back and get an actual FEBi if I can't find another genuine MB part before then. No big hurry. Not sure you caught my drift on the manufacturer ID thing,

I am just trying to perform due diligence as to if his parts are on the OK list or the other one. I won't mention any names. It seems unlikely at this juncture that it will turn out to be China poo, but it might be experimental, and who knows how that resolved? Reading the PAT and some of the panoply of links you can find through it makes it clear that this is NOT OEM, even if intended to fit. If this 'new' idea works it seems Giovanni Bartoli may have stumbled upon a solution to not a problem considering the current units are approaching 40 years of age and 200k miles and still not failed. Or maybe his would fail

What I am taking home is that this manufacturer is not well known here. Could still go either way. I haven't done these before on a benz, but my guess is the rear position will be the easier one ( right? ) and that is where the experiment will go if I keep it. I'm thinking of spray painting a masked stripe on the joints before disassembly to assure they keep their current non vibrational alignment.

Apparently this 'brand', whatever it turns out to be, is so obscure we won't find out much about it.

anybody else want to test it?

I don't know what model you have, but this may apply.

I now have an original OEM genuine in hand. very nice I just ordered a second. The item of discussion is on its way back to whence it came.


Many new details I won't bore you with unless begged.

Except for this. The OEM MB has the rubber islands ... 2 bolt holes to each on each face exactly opposite the other side. That weird one had them staggered. Thus, if you flip the OEM you are looking at the same thing regards the proud sleeves on the island. But if you flip the experimental one it changes with a flip because of the staggered nature of the islands. This makes me think that 1) it has to be directional as to side forward and 2) it will not work as OEM. DO the receiving flanges have accommodations for those protruding sleeves? or what is the point of their variance?

Also, whilst playing with this I noticed kool solid aluminum discs with flexible fittings in the European market, but not for most W126 Sort of a sport thing.

the flanges have the sunken bosses for the protusions.

The offset type disc is to cushion the "downshift" as you slow down with the old fully hydraulic automatics - the later electronic ones use the same solid disc front and back as the transmission itself is very well behaved and the "receiving generation" of these cars dont complain much on the downshift nudges.

MB went a step ahead to even remove those nudges with those offset type discs.

If I remember correctly, with Mercedes discs, the star faces the driveshaft for both front and rear discs. So with aftermarkets, it stands to reason to look for the name to be on just one side of the disc and mount accordingly. More importantly, the mounting bolt washers should not be against the yoke, but against the rubber of the disc.

Don't Chrome them; polish them

Both above seem to be telling: one of them faces forward and one backward, given they are identical. That seems to fly in the face of the fiber orientation notion previous presented. I am not arguing with anyone, but I'd like you guys to work that out and present the results Right now I am thinking orientation doesn't matter until I see it from an MB document. I will be paying close attention to how the old ones are mounted when I get this over the grease pit. I need to swap the trans out of that truck currently over it first, and I am getting so old and tired ...

sunken bosses? What are they? all I see are flush and proud bolt sleeves. From my research no "offset type disc" was ever spec'd for this model. Can you elaborate on what you consider that to be? Can you put a year on that trans idea? I assume you mean electronic control or not. We are in the Gen I W126 range here. So they are as you term 'old' ? This model in fact had differing discs early on then same discs after a certain serial number. ( in the same year) trans didn't change. Nothing else relevant changed. In fact I'm not aware I ever noticed a slowing down - down shift. I'll have to think about that while driving. It seems to not down shift until you request acceleration, so not a slow down type downshift as you mention. What is a nudge? and again, what do you consider to be offset type and what applications were they spec'd for?

Easily said but not so easy to determine what works just fine. That's what these forums are about.

Yes?
