I am replacing the M117 motor with a 1991 M103 motor from a W124. I need help with figuring out the driver side engine support. I tried to use engine support bracket from the donor car. The passenger side centers the crankshaft. The trouble is that for the driver side (left) bracket is slightly short and the mount hole needs to be go rearward about an inch. Can anyone give me a part number that will fit. Will the one out of 300SE (W126) work?
Also, what would be a good donor car for a front half of drive shaft that is 2" longer.
You can look up the pieces you need on the EPC and check against the part numbers of potential donor cars. Which I think is highly unlikely. The numbers will help you search the web and confirm what you find. Look in the General Data section for that link.
Use that same link and check with the MBUSA Classic Center if it comes to that. My understanding is they generally do better than the dealerships. With part numbers you can maybe cruise eBay.de a little easier.
Hmmm, not sure where you are looking on the EPC, but when I look at the EPC, it shows the 107 part number you quoted for the 300SL engine mounts, not the 103 number. The 103 number you have quoted matches the m103.982 engine, but engine mounts are listed under the engine suspension section for the chassis (24) not the engine suspension section for the engine. I think the 103 numbers you have quoted are the brackets that attach to the mounts.
Below is the picture I found on the web for W126 300SEL part no. 6032230604. The sweepback is something that I am looking for.
The part number for the right support that I am using form W124 is 6032232704. This puts the cranckshaft in the center of the engine bay. The EPC part number for the right engine support is 1032230104. I suspect the difference between the two are engine support to engine mount angle. W124 uses engine mounts that sit on a slight angle.
Buy it for the box and bits, then sell the motor if you can. Carb motor was only 150hp+/- with slightly lower compression pistons and less aggressive cams. And something about the rings, I believe.
Car was sitting around for 14 years and cams had pitted. I'm sure rest of the engine was in same shape. M103 choice for turbo application down the line plus decrease in Car's weight.
Spent all day taking the wiring out of the donor car. External wires were not too bad but once I got inside, it was painstaking. Got most of it out.
I'll be keeping my eyes open for the engine supports.
