Title: Rear Motor Mount Hardware
Post by: ddodson1 on November 03, 2013, 23:01:01
I'm replacing the tranny mount on my 1965 230SL.  I have the motor mount but cannot find the other hardware that needs to be replaced as well.

Can anyone suggest where I can order these parts?

- Upper and lower bellows
- Hexagon bolt and rubber bushing
- Sheet-metal cover

Thank you

If I was you I would forward my request to Tom, H (see below) Include your Vin Number and Transmission Number (should be stamped on your transmission or your data card.

If you don't have a data card Tom can provide it as well. Should you need a data card for your car then e-mail Tom 1) a photo of your car, 2) copy of your driver licence and 3) a copy of your ownership. Item 2 and 3 you can photograph it and include it in your e-mail to Tom.

Rolf-Dieter is right.  I bought those parts from Tom Hansen a few months ago.

Interesting side note:

 The main bracket that holds the rubber mount is a different part on the ZF 5 speed trans. I never noticed this before but the shape and spacing of the holes make this a unique part of this assembly.

Thanks for the suggestion.  I reached out to Tom and he is obtaining my data card and the hex screw from Germany.  I was able to order the other parts from Bud's Benz in Georgia.

Should have everything in a week or 2 so I can put it back together.

It took a while, but I finally got all the parts from Germany.  There wasn't much left of the original motor mount (picture attached of rotten parts and the rebuilt mount).

Got it all together then discovered a leaking fuel line.  Pinched it off and ordered the line.  Finally got the tank drained and the new line in then it snowed. :( 

Finally got some sun this weekend and took the car out.  Rides and shifts much better with the last old mount replaced!  :)

I just read the thread above with interest. I replaced my rear motor mount (1971 280 sl, automatic) about a month ago. The mount that I took out looked like the one that is in the picture above. It had a rubber skirt over it, just like the one above , although it was not worn out as badly, as a matter of fact  the mount looked quite good. The one that was sold to me did not look like the old one (no rubber skirt and about 1/4" to 1/2" lower in height). I assumed it was an upgrade and that my old one had collapsed that much. The new one locked almost identical to the front mounts. Within one month the drive line developed a vibration that I thought was the flex disk. It turned out to be the centering flange. The lock ring inside of the flange  had broken and the retaining spring had slipped back and allowed the centering ball sleeve to come of of the centering shaft of the transmission. My question is - are there different mounts - was the mount I put in too tall causing a misalignment
that wore out the internal parts of the flange? Or could this just have been a coincidence? I would like to know what caused this before I reassemble it with new parts and have the same thing happen again. Any input? Thank you , Chumps

I can't comment on the new motor mount causing the problem with the centering flange.  I can say the replacement motor mount is sold without the bellows (I had to order that separately from Germany) and did look very similar to the front mounts.  Also, the height adjustment is very important and I followed the specs in the Benz manual.  I've read this can sometimes require spacer washers.  Mine did not.  I would be concerned that you saw such a height difference (1/4" to 1/2" difference).

The rear mount is similar to the fronts but is quite a bit smaller in diameter.  It is actually the same size as a  190SL motor mount. Many suppliers are consolidating different varieties which are the same size and close enough.  Density of the ribber and the cut outs in the rubber are some of the differences.  

The bellows is simply a dirt and grease cover to protect it from engine oil and grease, which will shorten the life of the rubber. Normally these cars have about a 5mm shim between the mounting plate and the transmission mount.

I used to have a 190SL parts  customer named Dodson in Maryland about 35 years ago.  I was "SL Limited" back then, was that you?

Not I...This is the only SL I've owned and only came into my possession 13 years ago.

Thanks,

I'm installing a new centering flange - my question is: How much grease do I put in the center of the flange and cavity in the front of the drive shaft (where the grease fitting is)? I think too much would work it's way out and effect the life of the flex disk. Thank you, Chumps

When you assemble, you fill the cavity. As described in other threads here, you then keep on pumping grease into the zerk at the front of the drive shaft, until some grease comes out from the escape opening, opposite side of shaft.
Re: the grease going forward, there is a seal, a rubber ring, around the centering shaft. Be sure to renew this part also
