So....the new Engine mounts I installed that came in the trunk of the 116 when I bought it have already failed after 3 months.

I'm searching around for new ones and my two usual parts sources (Fastlane and Autopartsworld) both have several choices for the left mount, but only one choice for the right mount and both sources are out of stock.

I had always assumed the engine mount was the same part# for both sides on the 617. It seems when I did my 123 last year it was the same identical part for both sides.

Does anybody know if the 116/617 takes different mounts on each side, or is it the same?

Also...I'm going for the Lemforder or Corteco...think I'm safe with either of those brands?

Thanks,
Sam

Any idea what brand the mounts you installed were?

No idea...but they were obviously new. Foolish of me, I know, to install an unknown part... but lesson learned.

They are now completely flat and I get a lot of vibration, especially on the highway. I can feel it in my gear selector. I can take the engine and rock it back and forth with my hand and I get a lot of movement...more towards the back of the engine. I did replace my transmission mount when I did all this, but I am certain the cause is the engine mounts.

I bet the ones you had that failed were meyle... right before I bought my '84 300SD from Johnhef a year ago, he replaced the motor mounts and tie rods with new meyle parts. The mounts went flat 6 months ago, and all 4 boots on the tie rods are broken. I replaced the tie rods with lems, and the motor mounts with some of an unknown brand he had in a parts car.

So I guess I can't give you any useful advice other than "not meyle"

Lemforder is reputable - from Germany. Auothause sells Karlyn mounts, which they told me are made in the USA. I have Karlyns on my 123 and so far, no problem.

i got lemforders in the mail from ******** i believe. it's been a couple months now but i think that's the brand they sent me. maybe they send you whatever they have in stock, from one of a few brands they carry in stock

I have Karlyns as well...haven't installed them yet...

i think you're safe with lemforder mounts. in fact i have a couple in the trunk of my 300dt if you need a pair

It will probably just reduce the life of the mount.

Is it a heat shield, or a plate to keep oil/fuel from dripping on them?

I always thought it was to keep oil/fuel off them. Petrolium produts will
degrade the rubber.

Good point, now that you mention it I realize that I'm not sure. The FSM article that I was looking at repeatedly referred to it as a 'shielding plate', but did not say what it was shielding the mount from. Maybe we can figure it out based on where the shielding plate is used...


The FSM says that shielding plates should be used to protect both mounts for the 617 motor in the 116 and 123 chassis, but is needed on ONLY the right side in the 126. So, what's different? I've never poked around inside a 123 or 116, but the question we'd need to answer is whether something about the left side of the 126 protects the mount from heat or fluids that doesn't in either of the other chassis.

Or maybe the shield just doesn't fit in the 126 engine bay for some reason so they decided to skip it, and this line of investigation won't give us any useful information at all

Pricy little buggers aren`t they?

I have my shields, but haven`t put them on.
Iam usually checking the engine bay before I start the car ea time, so do a
visual for leaks, check oil, brake fluid, coolant etc...........

so catch anything as it happens. not too worried if they are on or not.

I also wasn`t aware of left and right side engine mounts. maybe because of the engine torque pulling on one side and pushing down some on the other depends on R & L.

Thanks, more evidence that I should search before I speak.

However, this still doesn't answer the question as to why the FSM (or at least the version of it I have on the CDs) says that a right side heat shield isn't required for the 126.120 chassis. Maybe I should take a gander in mine tomorrow and see if the arm that connects the mount to the engine has something heat-shieldy built into it, or if there's some (relatively) cool engine component nearby blocking line-of-sight to the block. (IP maybe?)

On the other hand, the chassis application for the right side heat shield (part # 126 241 04 34) listed by whunter includes the 126.120 despite what my copy of the FSM says on the matter. Maybe since the FSM was written mercedes changed their mind and decided it was needed on both sides...

There is a design difference between left and right.

We have both of the mounts in stock.
