I've been looking at putting a mercedes OM617 diesel (which was originally in the early 80s 300Ds) into either a 740 or a 940, or possibly a 240. I have plenty of experience swapping engines as well as welding and fabrication, so it seems like it should be fairly straightforward. Here are the main hurdles I've found so far:
- From what I've read the engine is a little too tall, so I'll have to modify the oil pan or the subframe, this doesn't sound too difficult.
- I'll have to figure something out for the transmission. It seems like the easiest option would be to either find an original mercedes transmission or put in a T5 (which there are adapter plates for), using an original volvo transmission would require fabricating an adapter plate myself and the gear ratios would be off.
- Since I'll probably replacing the transmission I'll probably have to get a new driveshaft as well.
- I believe I'll need a larger exhaust, nothing complicated there.
Other than that the rest seems pretty simple, it's a mechanically injected diesel so there's no wiring other than the alternator, and things like the warning lights and tachometer I can figure out.
Is there anything I'm missing? Does anyone have any related experience they can offer that would help?
