I need to remove this sprocket on my haybine to replace the bearing behind it. This is on the upper conditioner roller on a
New Holland 479 haybine. It seems the keyway is wedged in place to hold this sprocket on. There is no setscrew on either
side of the sprocket, seems its just the keyway being wedged in there that is holding it on (that I can tell). I for the life
of me can't seem to get the keyway out. My access is a bit limited but not real bad. I'd like to get to the keyway from the
backside and apply pressure, I've tried that with a prybar, couldn't get much pressure on it, had no luck, even with pounding
on the sprocket while prying. Tried a c-clamp, but couldn't get a good bite and that kept slipping off as I couldn't get onto
it squarely. I've heated it 2x and tried pounding on it to get movement, still nothing. Any other ideas for me to try??? I'd
like to get to cutting some hay here real soon. Thanks for any ideas that you may have.
