We dont have a magnum, but several of the neighbors do and there are two 7110's that are loader tractors in the winter and field tractors in the spring with between 10 and 11,000 hours on that have not been opened up, both bought new and one owner machines. My wifes grandpa has a 7120 he bought with 7000 and at 9000 the valve keepers let go knocking out a piston, they had it overhauled and have no trouble since. I have heard the engines are usually good for 8 to 9000, havent heard of any around here letting go at 6000, but it is posssibility they had a few bad apples. I think if yours is in the 6000 range you are probably safe, but onece it gets closer to 9000 you might want to think about a preventive overhaul, just my opinion on it. I am not sure on the years of these, but i think the 7110's of the neighbors were bought inthe late 80's. We have another neighbor who has been running magnums since they came out and still has one of the 71 series and the rest are the 89 series, he works them hard year a round and they seem to hold together fine.

The nozzles need to be pulled & ckecked if it hasn't been done at 2000hrs or less.Also the valve lash needs adjusted at that time.

That's what always happens to the original engine. I overhauled 3 7120's back to back in warranty with less than 3000hrs and many more after and the replacement parts would go alot of hrs, as they were messing with piston ring design on the early engines they had a steel insert for only the top ring and the second ring groove would fail and they finally settled on a steel insert for both compression rings, that fixed the ring trouble
