Any better ideas to get these nozzles out of 560IH

This tractor is spare parts one to keep the other one going. Going to have the nozzles & the pump gone thru & installed them onto the other 560 I have. I cant get these to last nozzles to come out. Of coarse the pullers are long gone from IH dealers. Have tried lube, slide hammer, chisels, pry bars, etc. thanks

Even if local dealer had the puller, there is no way to get the nuts underneath the bottom side of the nozzle as its seated against the cylinder head. The picture shows the nozzle up already.
 
This picture shows service tech removing the precup, would there be any reason for me to do this? I don't understand what the tool is grabbing, I don't see anything thread inside the precup? My 560D IH doesn't get used a lot & has sat for couple yrs without being used. Did get it to start, ran awful, tried some stanadnye fuel treatment from local injection shop. It helped some, but didn't clear it up.

The puller expands inside the pre cup to grab it. Sometimes they even worked.
 
Well, that FES46 puller sure looks like two big old ordinary 2-bolt pullers, looks like you could get something just like that at NAPA of O'Reillys. One pulls, one is braced against something.
 
Oh I see the problem. Wellll, one time I borrowed some sort of two-prong driver gizmo one time from local O'Reillys, I think it was to drive tie rod ends apart, or to drive some other two things apart. Two prongs, spaced correctly, slid underneath and I just drove the thing in, and it pushed the two things right apart. Worked slick. You might invent some such ting.
 
One last thought, ACTUALLY works for me several times; find the oldest guy at your local Case-IHC dealer, and ask him if they still have that old puller / expander tool laying around someplace.
 
Know anybody at a machine shop that rebuilds diesel cylinder heads? They usually have a variety of injector pullers.
 
Others can correct this approach which is only feasable if the injector does
NOT have an index that will not alllow it to turn. My suggestion is a large pipe wrench with a
cheater pipe to try to twist the injector in the hole. May need to cut a bolt off the next size larger
then the ear bolt hole. Then grind it down to drive in the ear hole that the pipe wrench jaw is
clamping against to keep from smashing/ breaking the bolt hole out. I don't know maybe the
injectors are way to fragile for this kind of treatment.
 
I have the pre cup puller, but have never used it. I've had good luck getting the injectors out so far. I'll bet they are stuck with carbon that seeped past leaking gaskets. Wonder if heat would help soften the soot buildup enough to help get them out?
 
We never had the IH recommended puller at the dealer. I rigged up my own version from pullers we had. But, when it came right down to it, a wedge like a chisel under each ear was what I usually ended up using. Bent a few ears but always got them out. The precups were a different story though.

This is what happens when someone pulls the nozzle and does not properly clean every thing, precup included , and replace the gaskets. If they seal they come out with easy.
 
Got #6 out finally. Tried pipe wrench on #3, it will turn a bit. Still cant get to lift up. #4 is a no go. Main issue is getting a nut underneath the head of the nozzle. Have to grind a nut to about a 1/8 thick, rigged up a puller. All it does it strip out threads that are left inside really thin nut. There isn't any way to get a jaw of a puller to go underneath either. Dad is going to try heating the area with propane torch. Running out things to try. Have left chisels wedged in there for a week or more also. Tried slide hammer, that's how we got out #6. Other 2 nozzles are really in there.
