As a last resort, Ill put a cold chisel to the offending piston, then bash out the bits Ill post when I have an update Gunner |

And you might seal up something in there for an end-of-travel bumper, like a golf ball or a few wine corks, so the piston crown doesn't meet the block-off plate with any velocity.

If the piston is 'say 4inches in diameter, then the force pushing up on the piston will be 14.7 lb/sq in x 3.14 x 4x4 =738.5 Lbs . This sound big, but a 10 ton press often won't shift a stuck bearing so I suspect you won't get much results. |

It would be perfectly reasonable to apply enough torque on the crankshaft to give 250psi on the piston, since it will see more than that in real use (WOT). But how do you calculate that? I'd go for a couple of times rated engine torque on the spanner before worrying about the rods. But presumably Gunner's already done that and failed or he wouldn't still have a stuck piston. I guess the moral is that before putting an engine to bed for a few weeks/months/years/decades you should pour some oil down the plug holes and bar the engine over a couple of times. Even if you are only going to flog it to Gunner in a decade or so. Mark Rand RTFM |

Before you go at it with a hammer and chisel take a drill and poke a series of holes in the piston. With enough holes you should be able to break up the piston. Seems it would do less damage to the block. Drill two holes and use a long sawsall blade on a sawsall. Wes |

PING GUNNER: FROZEN PISTON
I about drove myself nuts onetime trying to hammer out a piston from a RD350
engine. Took a lot of hammering to figure out that the cylinders block was floating on the crankcase. Once I bolted it back down with spacers instead of the head, I was able to maul the pistons out.

Sometimes it takes a week or even a month with Knight type sleeve valve engines that have iron pistons installed with .0015 clearance. Its got a half can of Kroil sitting in it, with periodic bashings using a 1x1 and a hammer, around the edges of the piston. ----== Posted via Pronews.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.pronews.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= - Total Privacy via Encryption =--- |
