Ensure that all components are clean and free from wear and damage. If necessary, replace any components that are worn or damaged. Refer to Specifications, "Exhaust Manifold" for the correct exhaust manifold tolerances. Refer to Specifications, "Turbocharger" for the correct turbocharger tolerances.
Clean all gasket surface's prior to assembly.
If necessary, install studs (43). Tighten the studs to a torque of 18 N m (159 lb in)
Position new gasket (42) onto exhaust manifold (38).
Install turbocharger (5) to the exhaust manifold.
Install nuts (41). Tighten the nuts to a torque of 44 N m (33 lb ft)
If necessary, install back pressure valve adapter (40) to the turbocharger. Refer to Disassembly and Assembly, "Exhaust Back Pressure Valve - Remove and Install" for the correct procedure.
If tube assembly (46) has been removed, position new gasket (44) and new gasket (47) onto tube assembly (46). Position tube assembly (46) onto exhaust manifold (38). Install new bolts (45) to the tube assembly hand tight and ensure that tube assembly can move freely.
