Disassemble and Assemble Procedures
Disconnect the pipe for the boost sensor (7) at the actuator (6). Remove
the circlip (1) that retains the actuator rod (4). Remove the actuator
rod (4) from the pin (2). Remove the nuts (5) from the bracket (3).
Remove the actuator (6) from the bracket (3). Do not attempt to
disassemble the turbocharger cartridge assembly or wastegate. Do not
remove the compressor wheel. The turbocharger cartridge assembly and the
wastegate are not field serviced, and should be replaced only as a unit.
Install the actuator (6) to the bracket (3). Install the nuts (5) to the
bracket (3). Tighten the nuts to a torque of 5 Nm (44 lb in). Connect
the bottom of the actuator (6) to a suitable air supply with an accurate
gauge. Operate the arm of the actuator by hand in order to check that
the valve is free to move. Push the arm of the wastegate valve toward
the actuator (6) and hold the arm in position. Slowly apply air pressure
to the actuator (6) until the pin (2) will fit into the actuator rod
(4). Install the circlip (1) into the groove in the pin (2). Do not
apply an air pressure of more than 205 kPa (29 psi) to the actuator.
High pressures may damage the actuator. Install the pipe for the boost
pressure (7) to the actuator (6).
Installation Procedure (Side Mounted)
Ensure that the turbocharger is clean and free from damage. Inspect the
turbocharger for wear. If any part of the turbocharger is worn or
damaged, the complete turbocharger must be replaced. Test the wastegate
actuator (19) for correct operation. If the wastegate actuator is
damaged or the wastegate actuator does not operate within the specified
limits, the wastegate actuator must be replaced.
Clean the mating surfaces of the exhaust manifold (12). If necessary,
install the four studs (13) to the exhaust manifold. Tighten the studs
to a torque of 18 Nm (13 lb ft). Install a new joint (14) to the exhaust
manifold (12). Position the turbocharger (6) on the exhaust manifold.
Ensure that the turbocharger is correctly oriented. Install the four
nuts (15). Tighten the nuts to a torque of 44 N·m (32 lb ft). If a new
turbocharger is installed, the bearing housing (18) and the compressor
housing (20) must be oriented to the correct positions.
Loosen the two band clamps (21) sufficiently in order to allow the
housings to rotate. If the band clamps are damaged, replace the band
clamps. Carefully turn the bearing housing (18) until the port for the
oil feed (17) is upward. Rotate the compressor housing (20) until the
compressor outlet is in the correct position. Ensure that the band
clamps (21) are correctly oriented. Tighten the band clamps finger
tight.
Ensure that the tube assemblies (3) and (10) are clean and free from
damage. Replace any damaged components. Position a new joint (7) and the
two setscrews (8) onto the tube assembly (10). Install the tube assembly
(10) to the turbocharger (6). Tighten the setscrews (8) finger tight.
Position a new joint (9) between the flange of the tube assembly (10)
and the cylinder block. Install the two setscrews (11) finger tight. If
a new turbocharger has been installed, check that the orientation of the
bearing housing (18) is correct. If the orientation of the bearing
housing is not correct, rotate the bearing housing until the tube
assembly (10) fits correctly. Tighten the two band clamps (21) to a
torque of 13 Nm (9.6 lb ft). Tighten the setscrews (8) and (11) to a
torque of 22 Nm (16 lb ft).
Remove the plug from the oil inlet port (17). 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. Use Tooling in order to lubricate a new O-ring seal (4).
Install the O-ring seal (4) to the tube assembly (3). Install the banjo
bolt (1) and two new sealing washers (2) to the tube assembly (3).
Install the tube assembly (3) to the cylinder block and to the
turbocharger (6). Tighten the banjo bolt (1) finger tight.
Install the setscrew (5) finger tight. Ensure that the tube assembly (3)
fits correctly. Tighten the banjo bolt (1) to a torque of 20 Nm (14 lb
ft). Tighten the setscrew (5) and (11) to a torque of 22 Nm (16 lb ft).
If the turbocharger has an exhaust elbow, install the exhaust elbow.
Connect the exhaust pipe. If the turbocharger has a remote wastegate
solenoid, connect the hose for the solenoid to the turbocharger. Connect
the air inlet hose and connect the air outlet hose to the turbocharger.
