Years ago we used a socket and breaker bar on the crank. Pull the plugs and fill the cylinders with Marvel Mystery Oil. Put a long piece of pipe on the breaker bar and hang a concrete cinder block from it and let the weight of the block slowly free it up. As the pipe moves down reset it and let it sit a couple more days.
This method will work if it isn't seized up too bad. It also does a little less damage to the cylinder walls.
It does take some time, if you have the time.

The cyl walls are toast of course, that's a no brainer those cyl walls will have no sealing ability anymore...so as for just getting the pistons out so you can bore and hone the cylinders ..try what these guys have mentioned , ATF, MARVEL OIL, DESIEL, BREAKER BAR ON CRANK...but in the end if they don't work 'see ATF sat on our willies flat 4 pistons for over a decade and never they came free' then the reality is an air hammer/chisill. If you can somehow get the all the rod bolts loose and slip the crank out...then just get a big hammer and punch and beat the **** out of them till they fly out.

This will probably be the reality of it....

Life is an experiment
So can you get the crank shaft out of it? That way you will be able to work on one piston at a time and not be putting force on everything at once.

I saw a guy fill the cylinders with kerosene & light it on fire. After that he poured kroil in the cylinders & let it sit overnight. Most of the kroil seeped past the rings. He put more kerosene in it & light it again. When that burned out he tapped the pistons down with an old hammer handle while it was still warm & the broke free almost right away. He put the head back on it & drove it for 3+ years. I never saw it smoke at all. It was an old Valiant /6 that was locked up tight!

Dude the pistons are in backwards...lol
Gee I wonder if the rods were flipped around during a re ring job..lol

Is it the photo doing that or are they in up side down?

Looks like valve marks on the pistons too, check for bent valves.

yep , for sure , the valves were hitting the pistons
:cheers:
That's another for the file. Nice eyebrows in the pistons where intake valve hammered them.
I agree the rods may be in backwards, chamfers to inside and dragging on the crank.
None of those pistons/wall look like they are corroded so badly as to be locked up!
Even looking at that build standing on your head, they are in wrong...
That is some funny Chit right there!

I would take off the rod caps you can get to. I bet those pistons will knock right out , then try to spin it to get the rest

If the crank isn't scared to Hell, he might get away with just reinstalling everything the right way and running it...but at this point its probably a grood idear to sheck evryting reer grood...lol

Haha, well...u build and install it next to the blast cab and use a harbor freight torque wrench. ;)
Hey I can't spell for ****...unless its a four letter word.lol
Good morning btw, how's the weather up there?

That would definitely scare the hell out of a crankshaft......
Good Morning Justin.....low 50's and cloudy. Spring is here, go form sunny & warm to overcast & chilly 5 minutes later. Predicting rain for most of next week, need to go out to the garage and finish the bike up so I can get a bit of riding in, just in case they are right.
