Typical example
Clean the mating surface of the exhaust manifold. Install a new gasket (10) over the studs. Apply Tooling (A) to the studs.
Position turbocharger (1) onto the exhaust manifold and install the double nuts. Tighten the nuts to a torque of 18 N m (13 lb ft).Note: Do not allow the lower nuts to turn when the upper nuts are tightened.
Ensure that tube assemblies (9) and (12) are clean and free from damage. If necessary, replace the tube assemblies.
Remove the plugs from the ports in the turbocharger and from the cylinder block.
If necessary, install the lower end of tube assembly (12) to the adapter in the cylinder block. Position a new joint (11) onto tube assembly (12). Connect the tube assembly to turbocharger (1) and install bolts (13). Tighten the bolts to a torque of 9 N m (80 lb in). If necessary, tighten the hose clips.
Lubricate the bearings of turbocharger (1) with clean engine oil through the oil inlet port. Rotate the shaft of the turbocharger in order to distribute the lubricant.
Install new sealing washers (8) and banjo bolt (7) to tube assembly (9). Position tube assembly (9) onto turbocharger (1). Tighten the banjo bolt finger tight. Install new sealing washers (15) and banjo bolt (14) to tube assembly (9). Connect the tube assembly to adapter (16) in the cylinder block.
Tighten banjo bolts (7) and (14) to a torque of 16 N m (12 lb ft).Note: Do not allow adapter (16) to turn in the cylinder block.
