Remove plugs and caps from tube assemblies. Ensure that tube assembly (13) and tube assembly (17) are clean and free from damage. Replace any damaged components.
Position a new gasket (15) (not shown). Install bolts (8) to tube assembly (17). Tighten bolt (8) to a torque of 22 N m (195 lb in).
Remove the plug from oil inlet port (23). Lubricate the turbocharger bearings with clean engine oil through the oil inlet port. Rotate the wheel of the compressor several times in order to lubricate the bearings.
Install a new sealing washer (14) to banjo bolt (12). Install the banjo bolt to tube assembly (13). Install the remaining new sealing washer (14) to banjo bolt (12).
Position tube assembly (13) onto turbocharger (3). Tighten banjo bolt (13) to a torque of 20 N m (177 lb in).

Use Tooling (B) to lubricate the bolt for V-band clamp (6). Position V-band clamp (6) onto elbow (7).
Position hose assembly (11) and elbow (7) onto the outlet of turbocharger (10) and turbocharger (3). Tighten the V-band clamp to a torque of 12 N m (106 lb in).
Tighten hose clamps (11) securely.
Ensure that elbow (1) is free from wear and damage. If necessary, replace the elbow that is worn or damaged.
Use Tooling (B) to lubricate the bolt for V-band clamp (2). Position V-band clamp (2) onto elbow (1).
Use Tooling (B) to lubricate the bolt for V-band clamp (9). Position V-band clamp (9) onto turbocharger (10).
Position elbow (1) onto turbocharger (3) and turbocharger (10).
Tighten V-band clamp (2) and V-band clamp (7) finger tight. Ensure that the V-band clamps are seated correctly onto the turbochargers.
Tighten V-band clamp (2) and V-band clamp (9) to a torque of 12 N m (106 lb in).
Connect hose assembly (4) to the wastegate actuator.
Connect hose assembly to air outlet (5) to turbocharger (3). Tighten the hose clamps securely.
