All I've ever needed was the I&T FO-31 manual.
Google it.
Kind of like a Chiltons if you remember those.
About $35 from most any New Holland Dealer, TSC, Fleet Farm, etc.
It will give you any specs and info you need for most major and minor repairs.
You bought a great model tractor by the way.
Those 3 cylinder Fords are virtually indestructable.
