Wow-Not much question about how most of the folks feel about this subject. Every Flywheel I seen taken off old tractors or trucks have scoring and surface cracks from excessive slipping of the clutch and heat. I have never heard of a Machine shop refusing to grind them because of liability reasons and do it for the purpose to get more use from them and those cracks don't grind out.
Am I missing something here or is it the general feeling flywheels with any defects should be replaced? I know the restorers tend to be perfectionist and money is not a object most of the time. How many of you have witnessed a Flywheel exploding?I have seen fan blades break and that seems to be a more imaginable disaster which could happen at any moment. cleddy
