I am attempting my first engine rebuild on an International 574. I removed the timing gear cover today and attempted to line up the timing marks between idler, cam, and crank (I removed the fuel injector pump earlier so I am not concerned about that gear). As I rotate the crank, I cannot get a single set of timing marks to line up, either the crankshaft to idler or the camshaft to idler. I purchased this tractor from someone just before the rebuild project, and it was running at the time of purchase. I am rebuilding the engine because coolant was getting into the oil and the bearings are very worn (I suspect from the coolant contamination).
Does anyone have any ideas why none of the timing marks will line up? Is it possible to set the crank at a known position and look at the cam position to determine if it is correctly timed?
