An inline 6 is but a v-6 is not. The physics of internal combustion engines is rather fascinating to read/discover. The 5 cylinder JD diesel is a rather noisy little beast and not nearly as smooth as my 3cylinder. [Reply]  [No Email]

I take it you mean internally versus externally balanced. Doesn't matter the configuration, the reciprocating assembly needs to be properly balanced or the thing's going to tear itself apart. A motor having more cylinders should run more smoothly. With 2, it fires every turn of the crank (unless it's a JD). 3 cylinders, every 2/3 turn, 4 cylinders, every 1/2 turn. 5 cylinders, every 2/5 turn, 12 cylinders, every 1/6 turn. [Reply]  [No Email]

I remember when I was at the dealership that there was a 5000 series tractor that used it. I think it was the 5325?? I cant believe that any engineer stood beside the thing while it was running and was proud of their work. It was beyond loud! It was worse than the 3 or 4 cylinders found in any of the other 5000 seiries at the time. [Reply]  [No Email]

One thing that started me to thinking about 5 cyl engines was that back a few months I sold an orange tractor that had a 5 cyl engine. It wasn't that fuel efficient nor was it that powerful.

Nice running, smooth engines. Power was OK, never heard any complaints, but I never heard about economy. They must have had a changing of the guard at engineering, because the replacement series used turbo 4's. Maybe just emissions though. Never did any major work to those 5 cylinder engines. They had a neat sound. Adrian [Reply]  [No Email]
