Hello friends,
Sadly, my beloved Ford Lehman (2715E) 120 in my single screw CHB 42' seized up last summer and disassembly inspection showed significant heat damage to the crankshaft and block. Miraculously I was able to source a different block and crankshaft, but the machine shop says the replacement crankshaft is also heat damaged and recommends sourcing a different crankshaft.
Cost-wise I would prefer to rebuild the Lehman 120 as they are great engines and would get another 10k hours out of it, but I'm not sure where I can find another crankshaft or if it's time to replace it with an engine I can get parts for?
Still figuring out options for LRC configuration with the new regulations for marine diesel engines, but have been looking at some possible replacement engines:
* Cummins 6BT 5.9 210 - have to replace shaft, screw, and trans
* Isuzu 6HK1X - great, but hard to find
* John Deere 6068/TFM50 (M1) - apparently great, but pricey
* FPT N67 150 - not much info
* BETA 85T - doesn't seem big enough
* Electrical conversion -- no, don't think I can do that
For the forum, anyone got a Lehman 120 crankshaft laying around or thoughts on a better long-term replacement?
Thanks!
