  2. Remove the right-hand push rod by pulling it outward from the oil seal in the center of the transmission drive sprocket.
  3. Use tool number 999-204 to hold the clutch (see Figure 10).  Fit the tool in the clutch hubs and rotate the clutch counterclockwise until the handle of the tool rests on top of the cush drive assembly.


  1. Remove the clutch nut with a 22 mm socket.
