Replacing O-Rings
• Before reinstalling the turbocharger,
replace the oil drain O-ring and the oil
supply line O-rings.
Turbocharger Installation
• Lower the Turbocharger onto the high-
pressure pump cover. Install the three
pump cover mounting bolts and hand-
tighten. Apply anti-seize compound to the
four exhaust pipe flange bolts and install
hand tight with a new gasket. Loosen the
crossover tube clamp and the turbine-
mating clamp.
• The following torque procedure should be
followed to assure the turbocharger parts
are allowed to align correctly to the
exhaust pipe assembly. First, torque the
three
turbocharger
to
mounting bolts.
Torque Turbine Mating Clamp
• Second, torque the exhaust pipe assembly
to the manifolds. Third, torque the exhaust
pipe to EGR cooler clamp. Fourth, torque
the exhaust pipe assembly to the
turbocharger
inlet.
This
correctly aligns the exhaust assembly; now
torque the crossover tube clamp and the
turbine-mating clamp. This procedure
ensures that the two turbochargers are
aligned before the components are tightened.
