Intermediate Bearing confusion

[Scutch]

I am replacing my intermediate bearing and the rubber donut that surrounds it on my 1968 230s.

The donut that I took off is completely symetrical. The one I bought from mercedes is thicker on one side than the other. You can see it here. http://www.***************/search/imageexpand.aspx?imageurl=../secure/PartImages/1114130012.jpg

Which side goes up, the thick or the thin part?

Thank you

Eddie

Fat section down .........

[Scutch]

I talked to a guy a mercedes that said that the part I have is wrong. He said it should be symetrical like the one I took out.

Have you used this asymetrical part? How did you learn that it goes down? I can't find it in any literature.

[Arthur Dalton]

The part you show does go as I told you, but it is for a 108 chassis ..you have a 114 chassis [ according to your sig] and that part is nothing like what you show.

I talked to the parts guru at Mercedes. You are right. For some reason when you use the part number 1114130012, which is correct, it shows up in all the after market pics as the one for the 108 chassis. And I was sent the part for a 108 chassis as well. I was mistaken. I got the part number from Mercedes and bought the part from ******** in Arizona. I'll try to stick to Mercedes next time. Their price on this one is alomost the same. Pain in the Butt.

Yes, I am ....

Arthur, his sig line says 68 230S, which would be a W111. A very few were sold as 1968 models. If he had just 230, then I would agree, W114/5. We need his chassis number.

A pic would be nice too.

Good point.

If he does have the 111 , then he has the correct part..if the part I showed fits, he has the 114 230/6..

Get us a Chassis#.

This is 111-413-00-12 and it is still a good #

And that part is shown in my Benz Service books as having the thick part facing down.


I have the Benz cross section geometrics and it does show the fat side as I posted in Detail.. BUT, it also has a cross section of the earlier center bearing support that is used on early bearings with grease fitting lube. That one shows a round/even sided donut. So, I assume the new replaces the old and the sealed bearing is all that is used today as a replacement.

I have a 111 chassis. I spoke with this guy Tom Hansen at the classic center. He told me that I have the part for a 108. An in fact, on these lopsided bushings the part number I order is 1114130012, but the number on the actual part is 1084130012. Tom assured me that if I had ordered the part from mercedes with that number 1114130012 that I would have gotten a symetrical bushing. When I try to order from ******** or anyone who seems to use the WorldPac data base, they don't even show an option for a 111 chassis. The best I can do is order as a 230 6-cylinder, and that comes up as a 114 chassis.

Well, then I would go with Tom on this one and just order it from Benz direct.
The first 3 numbers of the part are chassis designated, so evidently the only difference between the two is the shape, as the rest of the part # is the same.
I have plugged that # into several parts houses and they all come back as t the lop-sided donut....... ??????????????????
Looks like a WorldPak mistake to me .
The 114 won't work b/c it comes as a whole unit with the bracket , so I doubt it will fit.
What is the # on the OLD one??

SLS show it as symetrical, if I am seeing the picture correctly..

Look at 113 chassis/late [ 250/280sl] insert...part 86..that is part# 1114130012 ... same part as your chassis calls for.

For what it is worth, typing in 1114130012 in EPC shows this was used in a variety of 110, 111 (010, 012, 014, 021, 023), 108 (012, 014, 018, 019), 109 (015, 016, 018, 056, 057), 112 (014, 015, 021, 023), 113 (042, 043, 044) models. 111-prefix in part no. is not necessarily a direct link to car body. Several parts in my car are 110 and 108 designation. Part standardization and platform engineering was already starting back then.

1084130012 shows "nothing found" in EPC.

<111-prefix in part no. is not necessarily a direct link to car body. Several parts in my car are 110 and 108 designation.>

The prefix part can fit and is used on many different chassis , but it has to fit the chassis that it designates.
In this case , that parts is used and even listed in the 113 parts cat., but the part is from and designated to fit a 111 chassis production car.

How they decide the designation factor on a part that is used on all chassis is something I do not know, but any chassis of that vintage will show different cross chassis parts that are common to both/all of that type.
As an example,I have the parts listing and pictoral here for 113 drive shaft assembly page and EVERY part for the entire drive line, front to back is comprised of 110.111.108.189.112 parts EXCEPT the actual 2 Shaft Tubes themselves..which are 113 specific and start with 113 accordingly.
All remaining parts are from other specific chassis , but used on the 113 system.

[Scutch]

My mistake. The number on the part that is lopsided is 1084130112.

[Scutch]

Now I have another problem. Since I put the intermediate bearing in an put everything back
together I now have a grinding noise that started small and seems to
be getting worse after three days. It sounds like brake metal on
metal but isn't the brakes.

With the car overhead I accelerated a little and then had someone push
up a little with a bar on the very inside of the rubber center bushing
where the bearing is. With that motion I can create the sound a low
speed. This is the bearing I used:

Also in a parking lot if I drive in left hand circles the noise is
prominent. With right hand circles I can barely hear it. It also
seems worse when the car is slowing down or coasting.


Does that sound like the a bad bearing? It didn't seem likely that
something went back together wrong. It was pretty straighforward.

Thanks Eddie

[Arthur Dalton]

Some has a metal dust cup in front of the bearing and if not installed correctly, they spin on the shaft , making a metal to metal noise.
Is that cap on your unit??
