I have an 01' GHS with a 26 Kohler. Somehow today I managed to demolish my front hydro pully and hydor fan. It's the very first pully at the front of the mower. I removed the fan and the two set screws that I thought were holding what is left of the pully on. This did not loosen the pully at all, am I missing something or does it require a little elbow grease? I wanted to get a little info before I started prying on it. Thanks for the help.
