The input shaft on this Hydro-Gear pump has a keyway cut that retains/houses a piece of key stock, which rides inside of a broached slot in a pulley. The pulley has two holes drilled and tapped for a couple of small set screws. One goes directly against the key stock and the other on the shaft. This part broke and subsequently the belt was thrown and the mower could no longer move. The mower is a Bad Boy Outlaw XP 2016 and has less than 60 hours on it. I will supply pictures:...
