Both run kinda, we swapped the parts needed from the new one over to dads and it runs on fuel then dies pretty sure its sucking air into the system.The other one has a possibly bad injection pump, as it will run on ether which is how we loaded it.
Weve been super busy but we did fiddle with the ol 31 some were thinking its the steering box under the dash because everything else is tight and functions.
Oh that is true the cylinder isnt exactly new looking but he says it is the pump is pretty new looking hoses are shot though gonna try to get better pics and more info later on today.
The 31 industrial in my own opinion was a special mix breed type tractor, it shares parts with so many other models including the drivetrain but this one is different due to its logging setup that we think is either factory/dealership stuff or home brewed.
Thank yall for the help Im gonna be back out to help him monday so I can fiddle with it then and report back with what I find and see whats wrong from there.
So me and my neighbor use a 1970s era Massey 31 industrial logging tractor it has a new power steering pump (gear drive off the front gears of the engine) new hoses and cylinder, it steers fine when you first fire it up and take off but once the engine and pump get warm you have to lift the nose...
It spins over fine has great compression just havnt had a chance to get it running as its not a important project, my time has been dedicated to getting my work truck back up and going as its needed bad.
Well its been a while and ive gotten zero work done on the tractor due to other issues and once again its on the back burner so I guess I will get to it when I can.
