  3. Place rear chain link plate (10L) of the timing chain (10) in mount A1 (4).

    IMPORTANT Mount A1 (4) not yet inserted in the basic carrier (1G).

    IMPORTANT Only place timing chain (10) in mount A1 (4) as far as necessary until the middle link plate (10M) of the timing chain (10) can be mounted.

  4. Mount middle link plate (10M).
  5. Insert front chain link plate (10G) for the open timing chain (10) in the mount A1 (4).

    IMPORTANT The chain link plates (10G, 10L) and the middle link plate (10M) are fixed and guided by sprung pins (4S) in the mount A1 (4).

  6. Insert mount A1 (4) with engaged timing chain (10) in the basic carrier (1G).

    IMPORTANT Ensure correct seating of the timing chain (10) in the mount A1 (4) and the mount A1 (4) in the basic carrier (1G).

  7. Place the riveted link (10N) or thrust piece A2 (5) through actuation of the thrust spindle (1D) on the basic carrier (1G) on the timing chain (10) and check for correct positioning.
  8. Press in the riveted link (10N) through actuation of the thrust spindle (1D) into the timing chain (10).

    IMPORTANT In this way the spring-loaded pins (4S) are pushed back into the mount A1 (4).

  9. Turn back thrust spindle (1D) on basic carrier (1G).
  10. Detach basic carrier (1G) together with mount A1 (4) and thrust piece A2 (5) from timing chain (10).
  11. Modify grab handle (1H) for basic carrier (1G).

    IMPORTANT The grab handle (1H) of the basic carrier (1G) must be modified to avoid damage to the cylinder head and timing assembly.

  12. Insert outer chain link plate (10A) for timing chain (10) in the thrust piece A2 (5).

    IMPORTANT Check for correct seating of the outer chain link plate (10A) of the timing chain (10) in thrust piece A2 (5).

  13. Insert thrust piece A2 (5) with outer chain link plate (10A) in thrust spindle (1D) of the basic carrier (1G).

    IMPORTANT Ensure correct seating of the outer chain link plate (10A) in thrust piece A2 (5).

  14. Insert mount B1 (6) in basic carrier (1G).

    IMPORTANT Check mount B1 (6) for correct seating in basic carrier (1G).

  15. Insert timing chain (10) in mount B1 (6) and basic carrier (1G).

    IMPORTANT The open ends of the riveted link (10N) must point towards the thrust piece A2 (5).

    IMPORTANT Ensure correct positioning of the timing chain (10) in the mount B1 (6).

  16. Place the outer chain link plate (10A) or thrust piece A2 (5) through actuation of the thrust spindle (1D) on the basic carrier (1G) on the timing chain (10) and check for correct positioning.
  17. Press outer chain link plate (10A) through actuation of the thrust spindle (1D) onto the timing chain (10).

    IMPORTANT The riveted link (10N) must still be able to move after pressing on the outer chain link plate (10A).

  18. Turn back thrust spindle (1D) in basic carrier (1G).

    IMPORTANT The thrust spindle (1D) in basic carrier (1G) must be turned back until the thrust piece A2 (5) can be removed.

  19. Remove thrust piece A2 (5) from the thrust spindle (1D) of the basic carrier (1G).
  20. Insert riveting die B2 (7) in the thrust spindle (1D) of the basic carrier (1G).
  21. Lay riveting die B2 (7) through actuation of the thrust spindle (1D) on the riveted link (10N) and check for its correct position.

    IMPORTANT Ensure correct positioning of the timing chain (10) in the mount B1 (6).

  22. Rivet the riveted link (10N) through actuation of the thrust spindle (1D) using the riveting die B2 (7).

    IMPORTANT Using the riveting die B2 (7) both pins (10B) of the riveted link (10N) can be riveted once.

  23. Detach basic carrier (1G) together with mount B1 (6) and riveting die B2 (7) from timing chain (10).
