Update: The gear came off too darn easy, so it is pretty safe to assume the engine builder did not install it properly during rebuild (approx 2500-3000 miles back but also over 3 years ago). The gear has some indications on the mating surface that I am not comfortable with so I will buy a new gear. My cam (Crane) is predrilled and tapped so I will use the same tool for installing a harmonic balance wheel to ensure the new gear is on properly. Thanks for the tip on putting a 0.002" feeler gauge between the gear and thrust plate to ensure it is "home". Good thing my wife is out of town cause I am using the "Fry Daddy" with some 30 wt oil to heat the new gear. The new gear won't be here till tomorrow so I will let you know how it went when I crank it over.
