273 Rocker Arm to Shaft Clearance

Gray Cast Iron has a linear expansion rate of 5.8 (times 10 -6) where low carbon steel is 6.5 (times 10 -6). This is linear expansion per each degree change in Fahrenheit. The steel expands more than the cast if both would be heated equally.Aug 3, 2016

First you bring up your inclination to eat fly crap rather than address the known feces in your meal and now you are expounding on expansion rates of cast iron. :rolleyes: Neither the shaft nor the rocker arm is gray cast iron.
