  1. Hand start.
  2. While holding the outer diameter of the clutch pulley, torque the clutch pulley using a 17 mm hex tool, 75 Nm torque stick and an impact gun for 3-4 seconds. This makes sure the proper torque has been applied. Torque : 75 Nm
  3. Install a new cap onto the pulley with the rubber button facing inwards.
