To switch out the clutch pads you are going to need to first unplug the machine. Next take off the small sprocket on the right that the chain runs on (when you are in front of the machine) so the chain is loose enough to move the torque limiter and the large sprocket to get to the clutch pads. With a wrench unscrew the nut that holds the clutch pads on. (Remember the order that you take everything off in so you can put it back correctly!) Once the sprocket is off you can pull off the back clutch pad and replace them. Note: Put everything on in exactly the same order as you took it off!
