I changed my engine mounts with genuine over the xmas break. I used genuine as the MB dealer could get them overnight, which worked well timing wise as I was in the mood to give the old girl a bit of TLC.

When I took them out of the box I shook them. One was silent but the other I could hear the fluid splashing around.

Nevertheless, I installed them and now I have lots of things inside the cabin vibrating: door trims etc.

Vibration gets stronger if I rock the car slightly from side-to-side. Could I have a dud mount?

If it was just a bad wiper blade then I would take it back to the dealership but a mount means: car on ramps, jacks under engine, cross-over pipe removed and a couple of hours time.

Just wanted to see if anyone has shook a new mount before or perhaps works in parts and could take one of the shelf and check for me?

By the way, genuine mounts are made in Turkey (not stamped anywhere on the mount but in tiny writing on the box), my Corteco's I removed are made in Germany and boldly melted into the rubber of the mount "MADE IN GERMANY"

Are you sure you re-tightened them and back to specs? (measure twice cut once) Just a thought...

From what your saying thought, i'd venture to guess that one is a dud.. FLUID!?, uhh.. there shouldn't be any fluid as they are all rubber and metal. Unless the E300's different (i've only done them on my 240 but the E's are due this spring) but, from what i've seen, what their 'purpose' is meant for, I think that one was the dud. Agreed that's a real PITA job to do actually, not SUPER hard but, I wouldn't wanta do that again for a few years...

Maybe you could get the dealership to change the bad one out? assuming you remember where you put the mount that you heard the "fluid" coming from.. if not, there might be a way to do some diagnostic work and figure out which sides the bad one..

can someone confirm the procedure on how to isolate a bad engine mount maybe? Also, to confirm that engine mounts do not contain liquid?

I did my mounts over the summer and I do not recall any fluid shaking around in the new or old ones. I have a 99 so may be different, I don't know.

I guess you could order a new one from the dealer and see if you hear fluid in the new one, if not you know the deal.

They do in the 87; the mounts are hydraulic. I've actually never shook one ... I doubt it's supposed to slosh, but I'd be interested to see the answer to this one.

I would think you could jack up the engine with wood support to see if taking pressure off the mount would eliminate the shaking.

I looked my order up when I purchased mine and they were Corteco's.

I do believe the mounts contain fluid, However when getting mine from the dealer I was fixated on the fact that the new mounts were twice as thick as my tired old ones.
I never shook the mounts to see if they were being fluid filled, could have left that for my former secretary.

Can you check the installed height of the new mounts? You should be able to get a finger between the 'flats' on the mount and the crossmember.

They do contain hydraulic fluid- when I had a front/side shunt a couple of years ago one failed (right-side looking from front) and the fluid leaked out. Had really bad vibration at idle/very low speed 'till I changed it. Probably obvious, but did you make sure the small tab in the top of the mount was aligned with the notch in the engine bracket?

I don't remember the new one making a sloshy fluid sound, but I also may not have shook it to check

You don't need to remove the crossover pipe to change them out btw, or at least I didn't...

As Sixto said you should be able to get a finger in the gap between the frame and the bottom of the mount, it'll be obvious if it's failed.

Presumably the engine is now sitting higher...and if the gearbox mount is original (unchanged and hence sunken) this has the effect of lowering the gearbox tail shaft causing the front UJ to flex more. UJ can develop a sticky motion (not smooth operation throughout the 360 degree rotation).

I removed the crossover pipe because my extension bars were so close to the plastic parts on the IP, that I was afraid I'd break something off.

I measured and have about 15mm clearance between the bracket and the bottom of the mount, so that should be within specs?

There was one other issue I forgot to mention; when I ordered the parts there was some discrepancy for the part no. of the left side mount: the dealer supplied two (2) mounts with the same part no. 124 240 1917. But according to the EPC the left mount should be 201 240 5217 if A/C present, which it is: when he cross referenced 201 240 5217 it came back telling him to supply 124 240 1917.

I'm not sure what that means; do they no longer manufacture 201 240 5217 or did they later find a problem using that mount. If anyone has any knowledge of this It would be a great help.

Thanks as always.

Yes, I thought the same: so back to the dealership and ordered a transmission mount. The old transmission mount was original and definately needed replacement as the rubber was kind of gooey. It got 238,000kms which isn't bad, but the old one was made in Germany and the new genuine one is made in Czech Republic.

Not meaning to get into a round of bashing as to country of origin but below is a list of my latest bag of tricks from MB dealership and their origin.

Engine Mounts: Turkey
Transmission filter: Czech Republic
Transmission mount: Turkey
Ki piston spring: Germany
Bushing for accelerator: half label ripped off!
Accelerator spring: half label ripped off!
Wiper blade: Germany

The fact that I paid double the price (in the case of the transmission mount four times the amount) as what I could get OEM made in Germany, I was kind of expecting that the genuine products I get would be German made.

If you are getting parts from a MB dealer, you are being ripped off.
The local one down here gets many parts from non MB sources.
There is a guy (Abdul) down in Williamstown in Vic That gets MB parts by the container from his brother in Lebanon. His brother gets them from MB in Germany. He can sell for less than MB Australia can land them for.

Try sending
swea@bigpond.net.au
an email, he may have some suggestions of who to try in Sydney.

Its a pity that we have to use a third party to get bits from this site.
