a. Position turbocharger assembly on the mounting bracket and secure with attaching hardware.
b. Align exhaust system manifold turbo inlet and the turbine inlet and secure with clamp temporarily.
NOTE
The turbocharger is properly installed with the large diameter center clamp
loose to allow rotation of the turbine housing during installation for proper
alignment with the exhaust system inlet connection. Tighten clamp after
alignment.
When tightening any of the three V-band clamps, it is necessary to tap the
clamp all around its circumference to ensure proper seating. Do not rely on
tightening alone for proper clamp seating.
