You can take the bolt out that goes through the outside sheave of the pulley. You should then be able to pull the outside off. I think the inside pulley will slide offf when you get the outside off. I'm not for sure. When you put them back on, be sure to put the belts inside the pulleys. You cannot get the inside drive belt over the outside pullty. We had both of them off to put in a new feederhouse chain this summer, but I can't quite remember how the inside pulley came off. I will look when I get home this weekend. You can e-mail me if you have any questions about the combine. We have run a '76 7700 for 6 years. Good luck getting them off. Why do you have to take them off.
