I got it repaired :dance1: The new pully was a little bigger so my 79" belt was to small and went with an 81", an 80" might have worked but had to make a choice, also the new pully was two pieces (original was one solid piece) the center piece was machined for an opened end wrench so it could be held while the top nut was tightened, that was a pleasant surprise and made the repair much easier, the top nut threads were coated, I assume a lock tight or something like that. Since I placed an order for parts I took advantage and just tidied the mower up a little by Replacing some suspension bushings, bumper caps (I used black sealant when I popped them on so maybe they will stay in longer ) and steering/suspension caps.
Thanks TOTO
