The original subject was "Re: Detroit Diesel 271 Farmall M".

I've had a 2-71 in my Super M for over 10 years and haven't had a problem with my flywheel. I made the crank to flywheel
spacer myself, put springs in that are 10-20% stronger than stock and had the flywheel/pressure plate assembly balanced. It
pulled 86hp on the dyno at around 2,200-2,300 RPM. I usually keep it around 1,800RPM in the field. Can't say I'd use a stock
flywheel for higher RPM though but it's absolutely fine in this application. Do you have a 2-71 in a Farmall and are speaking
from experience?
 
A little related. I have a Sheppard Diesel 6M conversion engine,sitting in my shop that is designed to be installed in a Farmall M. It has a heavy flywheel adapter that adds lots of weight to the Farmall flywheel.It's called a 6m,but it's a 3 cylinder diesel,and I know Sheppard likes heavy flywheels on their engines.

2-53 in a Deere . Check with the farmall pullers for the rpms where the factory flywheel fails .
2050 rpm places twice the centrifugal force on the flywheel vs 1450rpm.
2300rpm is fine if the N series upgraded valve springs and cam follower springs have been used .
Should be able to make 90net HP with C80 injectors , a dry element airxleaner and a large muffler .
