7. Apply 20 mm (0.78740 inch) of Tooling (A) on the internal circumference in Positions (X) on the V-band clamp prior to installation.

8. Install new V-band clamp (9) onto stub pipe (10). Ensure that the V-band clamp is sufficiently loosened to allow installation. Ensure that the V-band clamp is correctly orientated.

9. Install tube assembly (4) into stub pipe (10) on the CEM.

10. Position V-band clamp (9) onto ring (7) and seal (6). Ensure that the V-band clamp is correctly seated onto the ring and the seal. Tighten V-band clamp finger tight.

11. Install gasket (2) (not shown) between turbocharger (1) and exhaust adapter (6), Install bolts (3) to exhaust adapter (3) finger tight.

12. Ensure that tube assembly (4) is correctly aligned with CEM. Use the temporary marks to align tube assembly (4) and stub pipe (10).

13. Tighten bolts (3) to a torque of 44 N·m (389 lb in)

14. Ensure ball clamp (5) is correctly positioned. Refer to Illustration 5.

15. Tighten ball clamp (5) to a torque of 35 N·m (310 lb in). Ensure that the ball clamp remains correctly positioned. Refer to Illustration 5.

16. Tighten V-band clamp (9) to a torque of 13 N·m (115 lb in).
