it was sitting for about five years, engine was stuck, got it free'd up. getting fuel to the injectors but it wont fire even with a little ether. slight smoke not all that much though.

At a loss, thinkig its a compression issue, valves sticking or broken rings. i just dont know any more. any new ideas would be greatly apprieciated.
thanks, jason
 
If it won"t run on that, then things are pretty bad, you have no compression, or no air getting in to the motor. Check the air intake and exhaust are free from obstruction, if o.k. then you have a compression problem, valves could be stuck if the engine has stood, or piston/bore prblems.
 
Can you hear one or more cylinders being weak as the engine turns over? As in 1 or 2 cylinders not coming up to correct pressure? I'd be sure the fuel is good & is getting to the pump. Check for ice blockage in the fuel lines if you are below freezing. Are the filters clean & letting fuel through? Is the return line from the pump open/ no blockage?
Have you had the pump off--did it get put back in correct time??
 
I guess it was running when they parked it all we took off is the starter to be rebuilt, and the intake hoses and the stack.

We had the injectors out and put a couple squirts of oil in the cylinders so I'm ASSUMING, its not a ring problem.

But it still won't even fire on ether and we have fuel comming out to the injectors.
I'd think it would fire with no fuel at all if there was ether being used.

This is my nighbors tractor and I've never had to deal with a stuck engine. I didn't know if the valves could stick or not or if they'd hid the piston.
 
It should fire with ether with no fuel at all or the fuel shut off shouldn't it?
If its valves sticking it must be a lot of them or I'd think it would try to run at least.
 
Are you using the factory either injection?

Those tiny tubes plug up and you might not even be getting the either to the engine.

No, we have the intake tube right off. Spraying ether right into the manifold.

Can you even pull start these? I think it has a hydraulic clutch.
I know I can't pull my 1086 but being my neighbors tractor I don't know as much about this one I'd assume its the same as mine.
 
Okay,

Then, you've got engine troubles; more than likely low compression, since the engine was stuck. That is to say, the engine may now be free but perhaps all of the rings aren't.

If this were my tractor, I shoot a can of GM's Top Engine Cleaner in the intake while cranking it over. Slop it down real good and let it soak overnight to see if the thing loosens up enough to at least get it started.

Also, do you have good engine cranking speed? No, ya can't pull 'em to start.

Another thought; perhaps you're up against the original reason it was parked to start with?

Just thinkin' out loud here,

Allan
 
If it was stuck and you freed it up how did you free it up? If the valves are stuck then it might be possible that you bent some push rods. If a valve is stuck in its guide then something has to give.
 
First thanks for all your time thinking about this thing, i really appreciate it.
We had penetrating oil down the injector holes to get it loosened up then cranked it over to blow it out, then squirted motor oil to lube and help with compression.
It cranks over good for about five seconds then slows way down, one week battery I'm guessing because we have it on a big battery charger , new starter. I guess it ran good when it was parked. They just used it for tillage and all the land was into hay.

I'm guessing you need to put some good batteries in it to get it to spin over better. I have a 4430 jd that if she doesn't get a good spin it'll never start even with either.
 
We put some lube down the injector holes then dropped the pan and put a board on a bearing throw and jacked it up
 
If it only turns over good a few times that could be part of the problem. You could pull a couple good batteries out of something else to throw in it, hook them in series and it will zip right over. Then if it doesn't start, you know you have other problems.

Today's fuel will dry out in the fuel system if it was open. Had to have the pump for a Ferd backhoe gone through because of it.

Just don't run it long with 24 volts to the system. But it will run without batteries, just pop the ground cable.

Try pumping the hand pump while you crank it. Toss a set of filters on it, it could have algae as well.
 
Well we figured it out. With all the cranking the hydraulic clutch was pumped up to pressure so we were able to pull it. Started pulling it and in about 15' it fired up. Then it went wild.
Started running away, the thottle did nothing, was running way over the governer. Probably 4000 rpm or more. Luckily we had the tube from the turbo to the intake manifold and there happened to be a 4 x4 in the rock box so I could shut it down with that otherwise there would have been some major engine work.
