doing the same thing now. Take the cover off of the fly wheel, stick a screw driver through the fins on the left side (there are holes on the bottom) this will keep the clutch assembly from turning. Then go back under the mower and remove the bolt from the clutch assembly. after the bolt is removed work the clutch assembly back and forth till it comes down, the belt should have enough room then. I need a schematic for the belt. it was broke so I never saw it while it was on
