speedy300Dturbo


I have never done the mount in a W123 with the turbo. Only the 240D and the biggest problem getting the Allen wrench in there was the metal shield above the mount itself. This may not apply to the turbo, but if you remove the center bolt from the bottom and raise the motor with a jack (put some 2x4s between the jack and the oil pan, then raise the engine with the jack) until you can spin the shield out of the way, or remove it entirely. Then you can get the Allen wrench on the fastener.

On a 240D the driver's side is the hard one, and you get all the fasterners from below. On the other side the two that hold the mount to the frame were accessible from above. In any case, since the turbo is attached to the manifold, and as you jack the engine up the turbo is going to come with it, you should gain some access.

You also have to remove the snubber mount on the bottom of the engine, near the bell housing. I once again am not sure this applies to the 300D turbodiesel, but the mount there is intended to limit engine and transmission movements. If you don't remove it I doubt you will get the engine up high enough to remove the old mount and shield. Note that as you lift on the engine, until you get to the end of the suspension travel, you are not lifting the engine relative to the mount structural supporting framework. I had to get atleast a couple of inches of travel to clear the oddly shaped engine strut knob end that fits in the top of the mount.

Good luck, Jim
