Default Badly Bent Rod

I was going through some stuff in my shop yesterday and ran across this rod. 12 years ago I bought two 2 1/4 hp galloway engines. The parts engine had a broken frame and this rod. There are no cracks in this rod but as you can see it is just slightly bent How is this possible with a cast iron rod It is kind of a neat conversation piece but It would be nice to find out how it got this way.

The rod is probably cast or forged steel and has a little more flex and forgiveness than cast iron.

Cool piece!

I had a John Deere engine one time that did that too. I opened the crankcase when I was restoring it and the rod had bent about like that. The piston was pushed all the way to the back of the cylinder and about 2 inches farther then it should have been. All we could figure was that it got water in it and when it froze it just pushed the piston back and bent the rod. Hard to believe it did that instead of breaking the head or block.

Probably a steel rod. I made steel for years and one application was for connecting rods, A high sulfur coarse grained steel -- has a lot of give was used for lots of connecting rods.
