    NOTE:
    • Avoid the contact with cooling fluid and oil, it will damage the timing belt and can not be reused.
    • When affixing the pulley, use two hex socket head bolts M6 x 40 (30 mm unthread and 10 mm thread). The bolt must be tightened the whole length of the thread. This way the pulley is prevented from moving out of position.
  2. Lock the crankshaft, using the EN-46788  fixing tool (1).
