My Custom 1980 W116 300SD Project - PeachParts Mercedes-Benz Forum

A Mercedes Sprinter van stopped in front of my house and delivered a set of new genuine engine mounts. They were $109.00 each after my MBCA discount, a far cry from the $4.93 each for aftermarket. However, Mercedes states a different part number for the right side because it needs a different shore hardness, while many aftermarket suppliers state one part number fits both sides.

I'm sure you get what you pay for. Put on cheap aftermarket mounts and you get more vibration and shortened life. I already have a genuine transmission mount on there anyway. I've heard too many horror stories of aftermarket engine mounts collapsing in short time to want to play that game. When I rebuilt my entire brake system with genuine parts, the weak link in the chain was the one set of aftermarket parts (Meyle parking brake shoes) I used that required much grinding and filing to fit.

I have heard that Lemfoerder makes a great set of engine mounts, but unfortunately, they do not offer the right side mount for my car and I'd rather have the correct shore hardness on the right side than use a left side mount on the right.

The passenger side mount was collapsed and causing the engine to tilt to the right and make the body vibrate.

The engine mounting arm was resting on the metal part of the mount.

Before raising the engine, I disconnected the throttle linkage.

The factory service manual also states to remove the intake tube, but I already have it disconnected due to not being able to use the intake funnel with Euro headlights.

To loosen the mounting arms to the mounts, there is a 10mm bolt on each side that needs to be removed from underneath the mount. I discovered that the right side bolt was missing, meaning the right side mounting arm was not even connected to the mount! I discovered the hard way that the W123 and W126 chassis use an 8mm bolt, so I had to use one off of my Universal turbodiesel project.
