Are you saying there is a woodruff key cut in the shaft in addition to the standard 3/16" keyway? I thought it would be shown on the PTO diagram on HF website but it doesn't show one.
EDIT: I'm sorry, I totally misread the question :doah: Key for the flywheel :laugh: No wonder they don't show one on the PTO side of the shaft, there isn't one. :thumbsup:
