Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums General Petroliana Discussion Rusty Rods and Cylinder Removal

I am trying to be REALLY careful and remove a perfect Blue Glass cylinder from a pump I just purchased to go into my Wayne 711. I have read the previous post cited below and understand all the pitfalls; but can anyone give some good advise on trying to un-screw the rod bolts. I know your suppose to go real slow 1/4 turn at a time in a pattern. but the rod bolts are so rusted I am afraid they will just break off. I have used penetrating lubricant, but still will not budge. I am afraid to heat them up with a torch due to the drastic change in temperature. Any insight or tips would be appreciated.

Thanks

Using an Eye Dropper give each one a drop or 2 of Muritic Acid, might take a few days to dissolve the rust.
Haste makes Waste & might cost more in the long run [buying another cylinder].

Use a zip cut in a grinder and cut them off, cut one and then the opposite one, easier to make new rods then fool with the old.

He is trying to save Cyl., as stated the rods are Rusty.

Have had the same problem. Depends on how thick the metal is below the top where the cylinder is. Have used oil, and heat of all kinds. Slow way is always the best, and have used simple propane torches also that heat the nut just a bit and allow for hardly any transfer of heat to top of metal head. Even a pinpoint acced. torch that pinpoints the heat has also worked. Just do not point down on the heat, just sideways on the nut.

Thanks for the feedback so far; the pump I'm taking the cylinder out of is a Wayne 665 to give you an idea of the size of the rods, nuts, and metal cap that is on the top of the cylinder.
