My son John called me this afternoon. He was doing chores over at Steve's. He was having an issue with Steve's 1070 Case. We had put it on spare TMR wagon.
John had serviced the tractor Wed. night. Mainly changed the engine oil and filters. He checked the oil yesterday morning and all was well. This morning it was one gallon low???? This was after maybe an hour and a half of running. He searched all over for an external leak. Could not find one. He filled it up with oil. He did the chores Thursday evening and this morning with it. It was another gallon low on oil.
So I went over and checked it out. It is burning the oil. The muffler is half full of oil. So we have a problem. It is not turbo-ed so an easy external problem is out.
So I took over one of our JD 4020s to run the TMR wagon with. I hauled the Case 1070 home.
After chores this evening I tore into it. Number 3 piston has a hole burnt through it. Looks like a bad injector was spraying a stream of fuel and burnt a hole in the piston. So now I have an overhaul to do.
The tractor only has 4600 hours on it. They are correct. Steve's Uncle bought it new and Steve bought it just two years ago. The tractor is clean as a pin.
The issue I have is how deep do we go. The sleeves actually look real good with out any ridges. They have some of the original cross hatch still showing in them. The bearing look great.
I am tempted to just get a set of rings, one new piston, set of rebuilt injectors, rod bearing, main bearings and resurface the valves. Just do an in-frame overhaul. The engine just does not show much wear. I really would not be afraid of running it this way if it was mine.
Plus this would be way less cost than a complete overhaul kit. Also I bet that I could have it done Monday or Tuesday.
What do you guys think??? I usually would say go clear through it and get a complete overhaul kit with new sleeves and pistons but this engine just does not show much wear. I know Steve's Uncle just planted and sprayed with it. Steve does not work it much harder either. He uses it for hay making chores and planting.
I also do not want Steve to have a high cost parts bill right now.(labor is not an issue. I will do the work for zip) I am really leaning toward just doing it like I stated above. Real quick and then just be quite about it. I have a friend that is a Case nut. I would bet that he has most of the stuff I need left out of repairs he has done over the years. He is a worse pack rat than me. LOL. I am going to go see him ASAP in the morning. Can't call him as he does not have any phone. He does not want to be bothered by one. LOL.
So guys lead me to an answer!!!
PS Steve should be coming home next Monday or Tuesday. There is some test that the results did not come back today. They thought that he would get to come home today. The concern is the circulation in his left leg. As soon as the results come back he should be good to come home.
So I am going to try to have the tractor done by then, one way or the other.
