Here's a Facebook video of some people who are working on an antique hit and miss engine with a badly stuck piston, and they have come up with a pretty clever way to persuade it to move. I think a similar rig could be made to mount a 10 ton porta-Power cylinder over stovebolt pistons, using the head bolt holes to anchor the push plate. Another setup could push on the bottoms of the connecting rods once the crankshaft is removed, using the main bearing studs as an anchor point. www.facebook.com/reel/1558368472534667Jerry

Kicking self for selling off my Taskforce trucks.
Still looking for an LCF or conventional big bolt in decent shape.

Ended up stacking enough fittings together to adapt the spark plug hole to a grease fitting. Grease gun popped it right loose.
Heck of a mess to clean up, but I was surprised how well it worked.
