I have a cheap air impact chisel that I put a blunt tool in. I cut out a round piece of 3/8" plate about 2-1/2" diiameter round and welded a big 1/2" nut in the middle. All you have to do is place the plate with nut in the middle of the piston and then the impact tool in the middle of the nut and start hammering. Some type of penetrant should be used around the piston. You will be able to tell when the piston begins to move in the bore because it will start to wiggle where it didn't when you first started vibrating on it. Go the next piston and do the same thing till each piston is free. Once you get all of them free have somebody put pressure on the crankshaft trying to turn it while vibrating on one of the pistons that ia about half way down the bore. It will work!

Now I've just got to find that air impact chisel. I've got one around here some where. Engine will have to be reworked. The guy had it for two years and it was three years into a rebuild. Guy said he never heard it knocking when a rod turned loose. Knocked a hole in the oil pan which is tin. An easy fix. I've look all around underneath. As far as I can see the block is OK. Crank looks OK too. But I wouldn't put it back together without taking it apart and giving it a complete going over. Should be a fun project. And just what I need for all the Black Locust thorns I grow around here. I'ver already change the 2N to all steel. But it thews up the ground pretty good. [Reply]  [No Email]

STUCK ENGINE I have an old impact chisel tool. years ago I fabricated a round flat piece of 3/8" plate and welded a big deep nut in the middle of it. When I get a stuck engine I take the head off and pour diesel fuel on top of the pistons and them take the impact with a flat ended tool in it and sit my fabricated tool on top of the piston and let it hammer. I've never failed to loosen the worst stuck and rusted engine with this thing. The crank won't move with the first two or three but when that fourth one breaks loose it will usually begin to move the piston down. Believe it or not it will usually loosen the stuck rings too because they are what is stuck to the cylinder wall and the vibration will wiggle the loose most of the time. You can tell if the rings are free by looking down beside the piston at where the end gap is and wiggling the piston back and forth to see if the rings move. Zane [Reply]  [No Email]
