1.
Ensure that the turbocharger is clean and free
from damage. Inspect the turbocharger for wear.
Refer to System Operation, Testing and Adjusting,
“Turbocharger Inspect” for more information. If
any part of the turbocharger is worn or damaged,
the complete turbocharger must be replaced.
2.
Test the wastegate actuator (19) for correct
operation. Refer to System Operation, Testing and
Adjusting, “Turbocharger Inspect”. If the wastegate
actuator is damaged or the wastegate actuator
does not operate within the speci
fi
ed limits, the
wastegate actuator must be replaced. Refer to

Typical example
3.
Clean the mating surfaces of exhaust manifold
(12). If necessary, install studs (13) to the exhaust
manifold. Tighten the studs to a torque of 18 N·m
(13 lb ft).
4.
Install a new joint (14) to exhaust manifold (12).
5.
Position turbocharger (6) on the exhaust manifold.
Note:
Ensure that the turbocharger is correctly
oriented.
6.
Install nuts (15). Tighten the nuts to a torque of
44 N·m (32 lb ft).
7.
If a new turbocharger is installed, bearing housing
(18) and 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 band clamps (21) suf
fi
ciently in order
to allow the housings to rotate.
Note:
If the band clamps are damaged, replace the
band clamps.
b.
Carefully turn bearing housing (18) until the
port for oil feed (17) is upward.
c.
Rotate 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 band clamps (21) are correctly
oriented. Refer to the turbocharger that was
originally installed for the correct orientation.
Tighten the band clamps
fi
nger tight.
