First, I want to start off and say that im new to the forum. I am 16 years old and doing my first manual conversion, so I may not know everything about being a mechanic. I have a 1981 Mercedes 300D W123 with the OM617.952 turbo diesel and auto transmission from a 1984 300TD wagon that I swapped in.



I was at a local Pull'n'Save and found a 1979 240D W123. It had the 4 speed manual tranny. I have already read so much about these manual swaps and decided i'll pull it out. So one Saturday morning, my brother and I pulled everything we thought we'd need for a manual conversion and for $140 dollars, I had a manual transmission, Flywheel, Clutch disk, pressure plate, Cross member, drive shaft, pedal, and shifter assembly, with all the bolts for everything.


School is out on Tuesday, so thats when shes going up and I'm going to pull the tranny. I have researched a lot about this conversion, but i dont really understand about balancing the flywheel to the crankshaft? I dont know how to find out if my flywheel is neutrally balanced.

Any help or tips about this conversion would be greatly appreciated. Thanks a LOT! -David
