My car is a w115 200d with manual column shift.

The steering wheel/shaft has about 3-4mm back and forth play and my horns would sometimes blow by itself especially when steering.

I took out the steering wheel and found the problem. I'm missing the snap ring that holds the bearing in place and keeps the shaft from moving back and forth.

Does anyone know the size of this snap ring? Being a benz, I'm guessing it's metric. I also need the size of the bearing in case anyone can remember.

I've attached a picture I found online to show the snap ring I'm missing.

I already replaced the 2 vulkollan bushes that usually cause the horn to blow by itself.

TIA

I believe the snap ring is part N000472042001. One of the russian epc pages lists its OD at 42 mm, but I have no way to verify if that info is correct. Unfortunately no inner diameter was given.

I believe the bearing is part A0189816110. It is listed as a needle bearing in EPC. I could not easily find a size for it.

If you have a local MB dealer, probably the best way to ensure the correct parts is to talk to the parts person and if these part numbers are correct, order from them. The retail price on the snap ring is ~$4 and the retail price on the bearing is $9.

Thanks for the info. Although, I think you're referring to the bigger snap ring along the outer race of the bearing. I was looking for the smaller one, attached to the steering shaft, it's about 20mm - I measured using a plastic toy-like caliper so I can't tell what the exact size is.

The bearing is a ball bearing type, I can't take it out and send it as a sample since this car is my daily driver.

Being outside the US, my local MB dealer doesn't know much about these old cars. Even the independent suppliers here rely on part samples instead of proper part numbers.

Nelman,

The horn problem is caused by a "Volkullan" ring. Take a look at this thread. It has all the information you need.

Okay, lets try again. (sorry about the wrong info above). The snap ring (called "lock ring" in EPC) is part N000471020000. The bearing (called "grooved ball bearing" in EPC) is part N000625006004. I will poke around a little to see if I can find any details on either of those.

I have attached the page from EPC, to help figure out if I have in fact identified the correct parts for you. This is from their w115 pages, but I could not look up the 200d specifically because the 220d was the smallest version sold here and EPC is limited primarily to U.S. models.

That new lock ring part number (N000471020000) is described on one of the russian epc sites as 20X1,2 DIN 471. It appears that DIN 471 is a common specification for these, and 20 mm is the ID and 1.2 mm is the thickness of metal. So hopefully that is enough info to find that locally. I will now head back into the land of google to see if I can find anything about the bearing.

And that bearing (N000625006004) is described on one website as BEARING 6004 DIN 625. If you search for some of that info, you can find images of the bearing you need and its detailed dimensions.

MSRP is in the US for the bearing is $20, but I was unable to quickly find a price of the lock ring from a MB dealer. Good luck.

Thanks for the link. I've already changed the vulkollan rings on both sides of the aluminum plate thing, it made shifting a lot easier though I still have the play on the shaft which lets it move further in causing the horn contacts to touch the 'bolt action' and thus blow the horn.

I'm guessing the 220d and 200d are practically the same car except for the displacement, so it should have the same parts. I appreciate you taking time searching for detailed info. I think this is enough to let me find the parts locally.

Thanks

The play on the shaft it caused by the steering coupling. Here's a pic of what it looks like.

If you go back to the thread I mentioned, all the information on pricing and where to get it is towards the bottom of the conversation.

[QUOTE=Baxterdown;3391601]I did the steering coupling a year ago so I'm not sure if it's suspect. Anyway, I may have to get down there after I sorted out the snap rings just to be sure. Thanks.

The play on my steering wheel is not left to right, it's rather forward and backward.

[QUOTE=nelman;3391605]AAAHHH!! That changes everything - The steering coupling corrects the left/right play.

Keep us posted!

Well, I was able to get a 20mm snap ring locally but when I already had everything out, it was not the correct size - I think it should be 1-1.5mm smaller.

I also bought a bearing from my local supplier, although I couldn't get the aluminum bearing housing off completely. I was only able to pull it slightly out. Any idea what else could be holding that thing in place? I can't think of another way to change the bearing without removing the plate.

I already removed the 4 hex bolts and the combination switch but it still won't budge. Do I have to take the whole steering shaft out?

Okay, so I feel bad that you took my advice and it wasn't correct. It was these websites where I thought it was saying that 20 mm was the ID of that snap ring:
DIN 471 External Retaining Ring | Fuller Metric Parts Ltd.
and
Standard External Circlips: DIN 471 Metric

But if I wasn't always in a rush while taking care of small kids, I would have noticed that in that first image, it appears that "d" and "d1" are dimensioning the same thing, so clearly that is not possible. I should have been more careful and I am sorry about that. So I have dug in again and found this document:
www.tehimpex.si/pdf/katalog_segerjevih_obrockov_din_471_472.pdf

And in that document, it is more clear that the 20mm dimension is the shaft diameter. And that the ID of the clip (now called "d3") is 18.5 mm. Just as you stated. Sorry again.

That made everything clear about the sizes. Don't worry about the incorrect ring, I can easily get another one not very far from where I live and it only took me a few minutes to remove the steering wheel anyways.

I'm happy to get the new info. You've been a great help, thanks.

I bought a smaller snap ring and installed it today. The axial play was gone and no more horn blowing while steering.

The only thing left to do is the bearing since I couldn't get the bearing housing out of the jacket tube. Any ideas?
