2950 damper pulley

[Pult Eater]

Does anyone want to hazzard a guess as to how to fix the keyway in the crank on which the damper pulley and hydraulic pump drive fit on a 2950?

How did it work loose? Was there noise or vibration?

My guess is the bolt holding the pulley on vibrated loose. It eventually fell right out and the pulley quit turning when the key wore out. The keyway on the crank is veed now. Not a good situation.
