So I finally got the tractor running. Now there is a loud noise sometimes intermittent and continuous all the time. I checked the bolts on the flywheel side and seem ok. The noise sounds like it is coming from the pto/pulley assembly. I didn't see a set screw between the pulleys. Tried a puller but didn't get to agressive as i didn't want to damage something. Has anyone had this problem and how is it removed? Thanks for your previous help. Also the band brake needs replacement. Is it easier to take the fender assembly off to gain better acess? Thanks guys and girls!
