IH 560 engine into a IH 706

I have the opportunity to buy a IH 560 with a totally rebuilt gas engine. Might get it bought for $2500. Good wide front. No fast hitch. My intent would be to drop it into a good IH 706 with a scored piston or two. The engine in the 560 had the crank ground, head worked over, sleeves taken out and cylinders bored to the 301 cubic inch engine. Of course with new pistons and rings. I think the engine was done right including boiling it out, etc. My 706 engine has some piston slap so I think it is sort of on its way out. Didn't know how much part change over it would take to make it fit????? Does the timing gear cover stay?? Manifold?? Flywheel?? Clutch?? Thanks for the information.
 
To make it right you need to change the front cover. It won't cost much to do yourself, but alot of labor. The plate the cover bolts to has to be change and to get it off you have to pull the cam. Which means you have to pull the pan, oil pump, lifters, push rods, all on each engine to swap out. I myself would do a cheap rebuild on the 706. You can put 806 pistons in it for less than 706 pistons & sleeves. It would most likely last another 50 years which should be long enough unless you are under 10 years old yourself.(lol)
 
You mentioned "cheap rebuild". In order to put 806 pistons in it the block would have to come out for boring right??? I don't mind doing a in-frame overhaul. My 706 wouldn't ever be worked hard again. It might be lugged from time to time but just not the hours/workhorse combination. I quit using it a few years ago because of a knock. Everyone says it is a scored piston. Been told that it could run for years that way. Just want to get it up and running again for a chore tractor.
 
I would not junk a good running tractor just for the engine. For that $2500 you should easily do an inframe. Then you would have a NEW engine.Not a junk tractor and a used engine
 
Check the rated speed RPM and the PTO speed RPM for the two tractors. I think the 560 engine turns close to 500 RPM slower than the 706 engine. If you need the PTO, you might be better off to either use the 560 as-is or fix the 706.
 
Not as difficult a switch as using an engine from a combine.

The front cover will need to be changed because the 706 front cover bolts through the sides of the frame compared to the 560 which mounts on top of the frame rails. You will not have to change the backing plate so you do not have to remove the camshaft.

You will need to use the 706 governor because the controls and speed are different.

If the 706 has an alternator the brackets from the 706 must be used.

The 706 has a larger exhaust manifold outlet that is located a bit different from the 560. The hole in the hood will not line up with the 560 exhaust pipe.

Both tractors can use the same 12" clutch. The flywheels have different part numbers but I have not had the occasion to compare them to see if they may interchange.

The two engines use different style pistons and cylinder heads. The pistons used must match the head style.

The cheap a$$ 301 conversion is reason enough to stay away from that engine.
 
yes you would have to pull the engine but that may be the easy part of it all. If you used the 560 engine you would have two engines to pull. Like DeltaRed said you can rebuild the 706 for less and not have a 560 parts tractor left over.
