Hello Everyone,

My motor mounts in my W110 are very collapsed, I have the parts and I will attempted to do this my self in the near future.

My question is, do I have to remove the subframe, or drop it down, in order to do this job?

I am thinking the answer is no, I can see all the bolts from the engine bay. By supporting the engine from below with a jack on a piece of wood on the oil pan, I should be able to loosen the bolts, raise the engine, and slip the old motor mounts out.

However, I started to read the MB workshop manual, and it shows that there are nuts on the bottom of the hex bolts which hold the mounts to the frame. So, that would mean underneath access is required to hold the nut to loosen the bolt? Has anyone done this job before on a W110 and can advise me?

Also, anyone have the spec of these hex bolts, in case they come out stripped. I was not able to source a supplier of these bolts. They are marked 35 in the parts diagram and 5 in the workshop manual. I have part number N914019008000 as the MB part.

See a screen grab of the manual diagram, red arrow to the nut in question. The parts diagram shows no nut. I also checked the front axel diagram, holes exist for these hex bolts, but no nut.

Anyone have a few photos of this job in progress, that would help a lot! Thanks!!
