I recently purchase a 720 Bobcat that has some motor issues. The unit had been in storage for at least 5 or more years and the coupling was stuck to the splined shaft of the pump. In an attempted to free it I managed to damage the pulley. I can't seem to figure out how to remove the pulley from the pump. I'm hoping I can either find a replacement or have a machine shop repair it. I have a service manual that came with the machine, but I can't find anything on removing or replacing the pulley. Any help or info would be greatly appreciated. I took photo's, but am new this forum and not sure how I can post them.
