HELP 1655 Quiting

I have an Oliver 1655 diesel which I really like as mid size tractor-- Except. For the past three years it will just quit working and I cannot find or figure out what's causing it. I use it planting corn with a 4 row narrow, 2 years ago it quit once, acted like it was out of fuel. Checked the tank it was 3/4 full, then the sediment bowel and cleaned, then replaced the fuel filter which appeared clean and the fuel just flows freely--i.e. nothing blocking the tank outlet. It restarted and finished the field. Last year it was half a dozen times and each time the same thing--check everything then it restarted. This year after the forth time the fellow planting pulled it out of the way and finished with a borrowed tractor. Went out to fuss with it and it restarted doing nothing.
I keep thinking the injection pump and will have it rebuilt (about $1000) if that is the problem but how do I be sure? Hate to spend the money and find out that's not the issue.
 
This gets discussed about every week with tractors using Rosa Master pumps. The plastic parts in the pump are going bad. To check it loosen the two screws on the little timing cover on pump and it should run OK. The broken pieces plug the return elbow on the pump.

My 2-105 has done that about three times when the fuel gets low. When I take the line off the lift pump,I can't blow though it and it won't leak fuel out. There has to be something in the tank on that one that stays suspended until it gets low,then it finds its way in to the line.

I remember way back in the day,Dad's Oliver 66 would quit for no reason. There was a wooden popsickle stick in the bottom of the tank. It would drift over the hole and plug it off randomly.
 
You are right about the pump. Sounds like a flex ring issue to me. Don't let anyone buffalo you on cost. Almost any shop worth a hoot should be able to help you for about 450-500 bucks. Any more than that you are getting hosed. Any less and someone is skipping something important. It does take some time to do one of these RIGHT and time equals money, but to many shops think they need to make all of their money off one guy. Call around and price shop and ask questions about turn around time and warranties. There are shops out there that can help you out without breaking the bank. I see a couple Roosas a week here and would be glad to help you if you can not find someone to treat you right. Al 231/757/0064
 
I had a kernel of corn down in the sediment bowl neck on the combine. That one let just enough fuel by to run under normal load,but work it hard and it'd die out.
 
Sounds like time for pump service, confirm by seeing if it runs OK with the two screw timing cover loose. If it runs with the fuel leak, but dies again when tight you found the trouble..
 
It's a gravity fuel feed system. So any gap at the sediment bowel mean fuel leakage, which isn't happening.
 
That's what I thought but fuel flows like normal, or seems to. It quit one close to the shop so I put compressed air on it--MISTAKE. Outlet was clear and I had forgotten to put the fuel cap on--fuel everywhere. Took the line loose at the other end-from the filter and blew it. Was clear. All the way to the pump.
 
What has kept me from just getting a rebuild is, I bought the tractor in the mid 90's and had to put a rebuilt shortblock in it. Which if I remember right came with a rebuilt pump.
I have a 1855 that would quit every round disking, really frustrating. I called a mechanic, he watched couple of rounds then walked up with a screwdriver, a drift and a hammer. Removed a cover stuck the drift in, tap it with the hammer and put the cover back. Said it'll run the season but you have to get the pump rebuilt. It did.

This 1655 just doesn't seem the same. But I do believe you all have convinced me.
