W123 engine mount replacement
 

The engine mounts on my 300D are totally shot. I have a few questions about replacing them though.

Firstly, can i just support the engine with the oil pan while i work on the mounts?

Secondly, is there more to this system then just the motor mounts? Is there an engine shock absorber(s)? Does it have mounts that need to be replaced? I am going to go through and replace everything while im doing this.

********az lists a front 'T' mount under engine mounts for an '85 300D. I have never heard of such a thing. I dont see it on fastlane so i'm a little suspicious if it really exists.

I don' think you will see it on your car, either.

noone is answering my other question. Is there an engine shock absorber on this car? I havent seen one but there are certain dark corners of the engine bay into which i have not yet ventured.

don't use a 2x4.. use a large 4x4 or 6x6

yes.. two shock absorbers...

clean out the allen screws prior to unbolting them from the top and bottom.

use a set of vice grips on the shaft to hold it in place so it does not turn.. thus making the job easier. Might as well order some new engine shock top mounts as well if the shocks are shot...

With the engine shocks, you will need to order the hardware kit. This has the needed rubber bushings and metal washers needed for the engine shocks.

Is this mount also what you are calling the shock?

No, those are the mounts, my '84 CD has at least one engine shock.

While your in there you may want to check and change out your oil-cooler hose if there is any weeping as you have to remove the mounts to get them in. Better to do all at once. Get some degreaser and pressure wash under the car, much easier to work in a clean environment. You'll be amazed how much better your car will ride.

Check out the wiki page. I wrote up step by step how to do this job. The width of the board doesn't matter as much as making sure it reaches completely across the oil pan.

the om617 turbo has two engine shocks.. one for each side. the om616 has one shock only

No no no no!:eek: Don't ever use vise grips on that shaft! There's a flat depression on the shaft that I think an 8mm wrench will hold it from turning.

I think the flats on the shock shaft is 7MM. I know it is small, and tight
to get the wrench to line up.
be careful with the engine shocks if you only loosen the lower end and jack up the engine. when I lowered the engine down, the shaft didn`t just drop back in the hole on the support. It hit the side and shoved the shock up through the top mount.
I think that top mount is like $50.00 ea.

I screwed up about 2 months ago, there was a guy on e-bay that sold
both shocks, both upper mounts and the lower hardware for $54.00.:(

have fun changing this stuff, you will be an expert when done.

I have two new 123 engine mounts for sale in the parts section for $26 shipped....

IF you remove the engine shocks before changing out the mounts, you reduce the risk of breaking the top mount. I made a little tool to keep the shaft from spinning from a small piece of black iron from Home Depot that I had left over from a different project. I had to use a drill and a dremel.
