Illustration 52 g01290961
Insert cotter pins (3) in latches (2) that hold the insulation in place. Note: The following steps are for the installation of the turbocharger on the engine.
Use a suitable lifting device in order to place the turbocharger into position on the engine. Note: When you are positioning the turbocharger, ensure that the turbocharger remains level. Ensure that the O-ring seals for the oil system are not trapped.
Install the main bolts in the mounting foot. Tighten the bolts to a torque of 420 N m (310 lb ft). Use Tooling (C).
Install the main mounting bolts with Tooling (A).
Connect the connections to the housing for the turbine inlet.
Connect the speed sensor connection.
Connect the turbocharger wash group, if equipped.
Reconnect the instrumentation.
Connect the oil system if the oil is supplied externally. Note: The turbocharger must be filled with oil prior to operation on the engine. After installation of the turbocharger on the engine, fill the turbocharger with clean engine oil at the oil supply port. Connect the oil supply line after filling.
