Turbocharger Mounting

• The turbocharger is mounted to the engine
at two points. The low-pressure turbine
housing is bolted to the high-pressure
pump cover and the high-pressure turbine
housing is bolted to the exhaust tube
assembly. The two turbochargers are
connected by the turbine-mating V-band
clamp that allows for minor angular
variances in the mounting surfaces. In
addition, the oil drain tube assembly is
made of three pieces, and allows for
changes in the mounting points.
• Note: Removal of the turbocharger will
change the relationship of the two
mounting points and require that a special
mounting and torque sequence be used.
See the Service Manual for further details.

Turbocharger Crossover Tube

• Air from the low-pressure turbocharger
compressor outlet is routed to the high-
pressure turbocharger compressor inlet
through the crossover tube. The crossover
tube is sealed at the inlet of the high
pressure turbocharger with an O-ring and
at the low pressure compressor discharge
with a press-in seal. If the crossover tube is
removed, the seal and O-ring must be
replaced. The Turbocharger Crossover
Seal Remover/Installer (ZTSE4676) is
required to remove and replace the seal.
