I managed to get the heads off of all the waterboxer's cylinders but one...
and that one I had to stand on in the driveway and whang it with a hammer
like it was a brake drum. Anyway it's out and now it needs to go back in. I
have the wrist pin pulled out of the piston about 1/4 inch past the piston
edge, so I've made a little progress, but now it seems that it does not
want to move any more, at least with what I am moving it with. I have a
bolt on my puller, about 3 pounds, and I put the head through and catch it
on the far side of the wrist pin, working from the front of the engine.

Does anyone know of a better way? A better choice of puller tools (I don't
have any fancy expanding collets)? Would about an hour of propane on the
piston crown loosen things up around the wrist pin?

Got the heads back, want to get on with this project.
