I need to rebuild my SC governor. I have it apart and the old needle bearings are rusted and don't look like they have actually turned in a long time. The output shaft has gouges where the bearings rode. Surprisingly the tractor ran pretty well you just had to move the throttle lever over half way to get it off idle. It was also hard to set a midpoint speed. Pretty much idle or 3/4 speed and up where the choices. I am wondering if using bronze oil light bushings instead a needle bearings would be a better choice. Moisture seems to accumulate in the governor housing and cause the bearings to rust. Bronze wouldn't rust. Anybody tried this?
