I've got a 580CK that is in really good condition with low hours. Someone several years ago kept pushing their luck with a bad starter, and now there are several spots in the flywheel that are bad. It's been sitting for about 6 years. The engine is free, and they claim they pull started it the last few times they used it. Can you pull start a hydraulic shuttle shift? (Has the shuttle on the left hand side of the steering column.) My big question is, how hard is the thing to split to get the flywheel replaced? I heard someone say once they split one with the loader on, is this possible? I haven't studied to see how bad a job it would be to remove it, but doesn't look fun. Serial is 8694347 is anyone can date this machine for me.
