Good morning everybody....I'm an 80+ year old man who is in trouble repairing the dipper cylinder on my 1974 Case 580B backhoe. I got the cylinder off the hoe, the cylinder disassembled, a new seal kit on hand, BUT can't get the 1-1/8" rod bolt out. I have tried everything. I only have a 800 ft/lb air torch tool and it won't budge this bolt. I have heated up the bolt head to red hot thinking perhaps there is Lock-tight on the threads. Was told there might be. This heat should have melted any if there was some. I have used much "force" in using a box end 1-13/16 wrench and sledge hammer. A 4 ft. pipe wrench on a 1-13/16 socket and a sledge hammer. I've been on the assumption the bolt is a right hand thread....COULD I BE WRONG? No where does the Case manual state it's anything but a right hand thread. Does anyone have any suggestions how to loosen this 1-1/8 bolt? (short of taking it to a Case dealer) I do not want to damage the hex head of the bolt. I have the rod clamp securely in a large vise by the eyebolt end. The bolt end is supported securely horizontally. I suppose I could melt the bolt head off and hopefully remove the rest of it. And then buy a new bolt. What is my problem?
