After I snapped the Allen key, I put a long reach, half inch, ratchet box end wrench between the firewall and engine to get those 4 bolts out. I got them out and thought the engine would pop loose, but nope. I don't want to force it off, so I decided to disconnect the hoses from the pump and slide it out as a whole unit. It doesn't look like a fun job disconnecting the hoses either. I may just cut the hoses in there, because they are all in bad shape anyways.
My 4020 revival(hopefully)
Hello, I'm new and this is my first question.
A friend has this and he is giving it to me for free to free up his yard where it has sat still for 5 years since the engine blew. It doesnt look real bad, it looks to be original and complete and not bent up frame wise or anything. I know for like a couple of thousand I can get one of these that run and look better and it's not like this is a real old tractor classic, but man, it looks cool.
My approach is to look it over real good, note broken things or missing things, see if I can get the engine to turn over by hand(has a cylinder head loosened up) go from there. In a perfect world I am hoping for a light rebuild on the engine, some paint and all good.
Or maybe this is a parts machine and not worth the effort.that is why I am here. Seeing these pictures, would any of you bother with this tractor in this condition? or should I part it out.. The price is free so I won't be out nothing.
thanks all.

The 4 bolts that hold the pump adapter to the engine would not provide a good enough shafts alignment by themselves, the block is machined with a step on it that the adaptor slides over to hold the adapter in perfect alignment. This is a tight almost interference fit, and will require some help to seperate. If using a pry bar look for reinforced parts of the block to pry against, and DON'T try and do it in one motion, do it in small steps in as many places as possible. Another option with the engine loose is to use one knee and hand to apply a side to side twisting motion to the engine and hold it there, then tap the pump end of the adaptor with a hammer a couple times, them reserse the twisting direction and tap the other side of the adaptor, rinse and repeat till it comes apart. Again don't get carried away and use a BFH to try and get it off in one huge smack.

Ps; I wish that tractor was close to me 🤔 I am not flush with boat loads of cash, but to me it would be well worth a repower to get it running again. Especially considering what you paid for it to begin with
But then again I have been into these tractors for about 20 years and know what I like 😁

But then again I have been into these tractors for about 20 years and know what I like 😁I confirmed it has a broken rod, lol. All kinds of bits and pieces in the oil pan. Besides the broken rod, the crank journal is scored badly, but I don't see anything else chipped or broke. Bottom of piston bores look good.
This engine has 1600 hours and a broken rod. I guess I'm going to decide on where I want to go with this project. I'm not sure if the engine is good to rebuild, guess I'll spend time taking it down to the block and measuring things out. So would this thing be rebuild able or should it be parted? Lots of hours, broken rod and aluminum block. Heres some nice pics of the carnage

Looks like just aluminum scoring a little muriatic acid will clean that off. Clean it up and measure everything and you should be good to go ! Ive attached a picture of mine as an example
