7. If a new turbocharger is installed, the bearing
housing (18) and the compressor housing (20)
must be oriented to the correct positions. Refer
to Illustration 70. 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 (4) and (7)
are clean and free from damage. Replace any
damaged components.
9. Position a new joint (13) and the two setscrews
(14) onto the tube assembly (4).
10. Install the tube assembly (4) to the turbocharger
(12). Tighten the setscrews (14) finger tight.
11. Remove the plug from the oil inlet port (17).
Refer to Illustration 70. 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.
12. Install the banjo bolt (9) and two new sealing
washers (10) to the tube assembly (7).
13. Use Tooling (A) in order to lubricate a new O-ring
seal (6). Install the O-ring seal (6) to the tube
assembly (7). Refer to Illustration 72.
14. Install the tube assembly (7) to the turbocharger
(12). Tighten the banjo bolt (9) finger tight.

15. Install the exhaust manifold (1) and the assembly
of the turbocharger to the cylinder head. Refer
to Disassembly and Assembly Manual, "Exhaust
Manifold - Remove and Install" for the correct
procedure.
16. Install the setscrew (8) finger tight. Ensure that
the tube assembly (7) fits correctly.
17. Position a new joint (3) between the flange of the
tube assembly (4) and the cylinder block. Install
the two setscrews (5) finger tight.
18. 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 assemblies (4) and (7) fit correctly. Tighten
the two band clamps (21) to a torque of 13 N·m
(9.6 lb ft).
19. Tighten the banjo bolt (9) to a torque of 20 N·m
(14 lb ft). Tighten the setscrew (5) and (8) to a
torque of 22 N·m (16 lb ft).
20. Install the fasteners for the tube clips (2) to the
cylinder block.
21. If the turbocharger has an exhaust elbow, install
the exhaust elbow. Refer to Disassembly and
Assembly Manual, "Exhaust Elbow - Remove and
Install".
