No, it was an impossible solution. I suggest you learn more about engines.
On some engines, the bore of one or more cylinders falls completely between the main bearings, and a piston can be removed this way.You want to say it can't work.on the OP's specific engine, that's fine, we're not all going to be familiar with this particular unit, and it'sit's still worth suggesting.
You want to say it can't be done on any engine, while being a knob about it? No.

Name one. From a car, truck or tractor.
One of the smaller US Ford V8s, IIRC. I saw someone show it in a video years ago and thought "huh, that's a new one..."Austin 7, technically, but that's cheating as the block separates from the crankcase thus removing the issue you're concerned about.

For goodness sake, stop being a knob. I made a suggestion and it is likely wrong, it was just that. Can we move on? The common theme here is trying to help someone who asked a question not trying to score points.
Trying to help someone when you don't know anything about the problem is NOT helping. It's just flapping your gums. It detracts from the actual help by creating noise which distracts the OP from the actual help being provided. People who post nonsense about stuff they don't understand ARE the ones trying to score points. I'm trying to actually help. Now do us all a favour and go away.Mignon said:

Get over yourself. 
Hi Guys. Interesting discussion on whether a piston can come out the bottom of the block. Most I have seen won't. This one may do so, as it looked like a bit of space between crankshaft bearing abutments, but I wasn't going to pull the block out to see. I cleaned the coke off the bore and filed around the top of the bore where the top ring was jamming, oiled it and bingo, out it came. New piston in, caps on, head replaced torqued down to 100lbs, and rockers on, ready to connect diesel injector lines, hoses and exhausts. Thanks for your comments and keep up the discussions.....John

That pretty much had to be the problem from your original description. It's not uncommon. Logic and intellect are generally better problem solvers than brute force.
