4032 alloy, more silicon contains compare to 2618 alloy, lower noise, higher tensile strength, lower thermal expansion coefficient. High precision, 0.001 mm tolerance for pin hole, 0.005 mm tolerance for diameter, clearance between cylinder to skirt is 0.04-0.06 mm. ...
“I like heavier wrist pins because they deform less, and when they deform less you have less load on the pin into the rod,” said Molnar. “Getting pistons and pins too light can be a problem. The really, really light parts, I won’t make. I’m looking at some 3D models of part...
