I was cutting hay all day yesterday with my old diesel 4020 and after about 6 hours of a good productive the engine started loading up. Looked back at the disc mower and raised it up to,see if it was clogged. Then the engine started really loading up and putting out a black smoke. Half a second later it sounded like a top end rattle and I shut it down.
Temp gauge was at 240 degrees F instead of the 175 it had been at all day.
I let it sit about 4 hours and the radiator is full of coolent and the crankcase has the correct amount of oil.
I then turned it over with the throttle in the stop position and it sounded fine. Then I cranked it right up and it sounds normal with the same as always 60 psi of oil pressure.
How much damage can a few minutes at 240 degrees do to these engines?
If not much them what the heck happened?
I am going to check to see if the head gasket leaking into the cooling system and change the oil and see what comes out of the crankcase.
I know no one can tell me how much damage if any is done.
Could the pto system be locking up and did this?
I have only ran it about 10 min after it cooled down and I will not run it again until I find out what happened.
Thank you for any advice.
