7. If a new turbocharger is installed, the bearing
housing (18) and the compressor housing (20)
must be oriented to the correct positions. Follow
Steps 7.a through 7.d in order to orient the bearing
housing and the compressor housing.
a. Loosen the two band clamps (21) sufficiently in
order to allow the housings to rotate.
Note: If the band clamps are damaged, replace the
band clamps.
b. Carefully turn the bearing housing (18) until the
port for the oil feed (17) is upward.
c. Rotate the compressor housing (20) until the
compressor outlet is in the correct position.
Refer to the turbocharger that was originally
installed for the correct orientation.
d. Ensure that the band clamps (21) are correctly
oriented. Refer to the turbocharger that was
originally installed for the correct orientation.
Tighten the band clamps finger tight.

8. Ensure that the tube assemblies (3) and (10)
are clean and free from damage. Replace any
damaged components.
9. Position a new joint (7) and the two setscrews (8)
onto the tube assembly (10).
10. Install the tube assembly (10) to the turbocharger
(6). Tighten the setscrews (8) finger tight.
11. Position a new joint (9) between the flange of the
tube assembly (10) and the cylinder block. Install
the two setscrews (11) finger tight.
12. 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 N·m (9.6 lb ft).
13. Tighten the setscrews (8) and (11) to a torque of
22 N·m (16 lb ft).
14. 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.
15. Use Tooling (A) in order to lubricate a new O-ring
seal (4). Install the O-ring seal (4) to the tube
assembly (3).
16. Install the banjo bolt (1) and two new sealing
washers (2) to the tube assembly (3).
17. Install the tube assembly (3) to the cylinder block
and to the turbocharger (6). Tighten the banjo bolt
(1) finger tight.
18. Install the setscrew (5) finger tight. Ensure that
the tube assembly (3) fits correctly.
19. Tighten the banjo bolt (1) to a torque of 20 N·m
(14 lb ft). Tighten the setscrew (5) and (11) to a
torque of 22 N·m (16 lb ft).
20. If the turbocharger has an exhaust elbow, install
the exhaust elbow. Refer to Disassembly and
Assembly Manual, "Exhaust Elbow - Remove and
Install".
21. Connect the exhaust pipe (not shown). Refer to
OEM information for the correct procedure.
22. If the turbocharger has a remote wastegate
solenoid, connect the hose for the solenoid (not
shown) to the turbocharger.

23. Connect the air inlet hose and connect the air
outlet hose (not shown) to the turbocharger. Refer
to OEM information for the correct procedure.
