Have cockshutt 50 diesel standard bore. Replacement pistons are close to impossible to buy. One fellow has 60 over manufactured from another engine but not having oil ring below wrist pin and most likely not close in weight. The Cockshutt piston is two oil rings.This remanfactured piston is from a gasoline engine requiring a deep valve relief most not likely as strong and would require boring one cylinder too be bigger. As one can see balance problems are possible but not likely with the slower rpms. My thinking is thus my original piston is solid except for a small area of the top ring land broken out near the machined valve relief. Why not just leave the top compression ring out. Not a working tractor . Yes starting due to much lower compression is comprised, however it's only on one piston. I can get a 30 over piston from Phil H. He has only one.The cost is not so much an issue as availability. My one son who is a mechanical engineer can turn the piston down, however due to issues of re chucking an skirt flex it's not as simple as one would think.
