Default Re: How did this happen?

Did you look to see if either gear still had it's woodruff key in the keyway? If either gear was ever taken off and put back on, the woodruff key might not have stayed in the keyway and spun out once you got to high speed then lodged between the gears. Only other think I can imagine is a washer or something was left behind in the clutch case and got caught between the gears or one gear tooth broke off and stayed between the gears causing a chain reaction.

Those gears start as powdered metal I believe. Might have been a defect in manufacturing.
