for $94 a piece.....
I nearly bought some ebay ones for half that until I read some internet posted issues with the quality
1) anyone know of cheaper Lemfoerder's or other reputable brand but cheaper than Autohaus?
2) there was a report tha MB have different part numbers for Left and right possibly due to the different duty requirements....can this be substatiated or is it just an MB catelogue thing?

 

I looked and some models list a left and right but only one part listed for the SLK32.
Cannot find anything cheaper though.

 

Sorry I can't add anything, other than when I looked up an SRT6 on that same site, it was listed as made by Febi.

 

Interesting - possibly beause the SRT6 and SLk32 have different engine mounts.....
I treid SLK320 as well - same deal $$$$....but different PN again....strange. I thought the SLK32 and 320 would have had the same.

 

I need to replace mine as well, my shifter move forward about 1/2" under hard throttle. I see you've been in the poly fill thread as well Billy.

 

hmm....dont know how to take that....not welcome?

 

Just saying that I have been doing some research and I am just subscribing to your thread here. I was interested in what your opinion is after reading through the poly fill thread and wondering what your plan is.

I need to find a set of replacement mounts but only want to do this project once. I am hesitant to install factory OEM mounts as they may just fail again. I don't really have the time it takes to make a set of poly fill ones right now.

Beaner used the V8 engine mounts and said they are similar to the srt6 ones with about a 1/4" increase in engine height. I would suspect that a CL55/E55 engine mount would be stronger?

 

Raising the engine and keeping the same tranny mount would put the drive line out quite a bit. The flex disks and bearing would be at different angles. More flex at the disks is probably not good as I am sure that they last longer with minimal flex.
Just an observation not based on any experience in this area though and I could be wrong .....again.

 

180, if we arbitrarily assume the distance between the motor mounts and the tranny mount is 2 feet ( probably wrong, but close ), then a 1/4" higher motor mount would result in an angle increase of 0.59675 degrees at the flex disc.
I'm not sure 6/10 ths of one degree would make a big difference, maybe so, maybe not.
( I used the online calculator at Angle Calculator )

ditto to the "Just an observation not based on any experience in this area though and I could be wrong .....again."

 

I agree but any increase is not good. That angle translated to the flex disk is quite a lot, a 6" diameter disk would flex +/- .031 for a total of .062 more than it does now. I used my trusty HP 41CV calculator.

Clearance at the top of the engine is reduced and in Beaners case he had interference (V8).

 

Good point .......

 

wow a 41CV....what can I say...now that was a good era.

I'm heading for stock I've recieved my new ones - just checking out the process....ie: engine lifter or an alternative.
I'll refill my old ones with 60 poly + possibly a torque bolt setup.
If I dont end up with a torque bolt - the refills will be there if ever needed and it soundz like they will be after I get over 400hp

I dont see the refill taking a long time - an afternoon in the shed with some power tools...is always therapeutic.

 

Only one thing wrong with your final statement, so I'll correct it.
"I dont see the refill taking a long time - an afternoon in the shed with some power tools and a case of beer...is always therapeutic."

 

As long as your old ones aren't in 2-pieces like mine were...

 

Installed new MB motor mounts today. The old driver side one was completely torn apart into two pieces. The passanger side appeared that it was still good but removed it anyway. Now I have a set that I can play with for a set of poly fill.

 

If you don't mind, where did you get them from? I've got to do mine.

 

The V8 mount and the v6 mount look identical, I had one in each hand and could not tell the difference other than the part number... Since the v6 is lighter, my guess will be less than a ¼" difference in height if you were to put the v8 mounts with your v6... So do some more calculating

 

Rob at Needswings. He figured out the right part number and they have a 12 month warranty on them. He shipped them very quick too.

 

I put the OEM ones in about 2.5 yrs ago. Still good. Got mine from autohausaz like others. If you look up a 2004 SLK 32 you'll see them. Cheapest place I could find for OEM mounts.

 

yes - same here - autohausAZ was the cheapest for quality units (not cheapies)
