1.
Loosen the clamps that attach
the air inlet tube to the inlet for the
turbocharger, and remove the hose
elbow from the inlet to gain access to
the turbocharger.
2.
Loosen the hose clamps on the
turbocharger oil drain-tube hose,
located between the two sections
of the oil drain tube. Slide hose up
drain tube towards turbocharger.
Depending on the turbo orientation,
the oil drain tube may need to
be completely removed prior to
removing the turbocharger.
3.
Disconnect the oil supply hose at
the turbocharger.
4.
Remove compressor outlet boost
tube hose from compressor outlet
elbow. Leave the elbow attached to
the compressor housing. Stuff a small
shop towel or rag into the end of the
boost tube to keep foreign objects
from entering.
5.
Remove exhaust V-band clamp
and loosen any remaining clamps to
allow the turbine outlet pipe to be
pulled away from the turbocharger.
6.
Note the orientation of the
compressor housing and stock boost
reference nipple in the vehicle. The
Banks BigHead actuator must be
installed in the same orientation.
When the new assembly is installed
the orientation of the compressor
outlet should remain the same.
Remove the turbocharger mounting
nuts and the turbocharger from the
exhaust manifold.
CAUtiOn: Anytime the
turbocharger is removed from
the engine, take care that no
foreign objects enter any of the
turbocharger connections on
the engine or the turbocharger.
Foreign objects entering air,
exhaust, or oil connections
may cause major damage to
the engine and/or turbocharger
and is not covered under any
warranty. Cover the open end of
the intercooler pipe with a rag,
as this pipe is very susceptible to
foreign object entry.

7.
Clean and inspect the exhaust
flange mounting surfaces on the
exhaust manifold. Make sure the
surface is clean and dry.
8.
Stuff a small shop towel or rag
4 to 5 inches into the rear exhaust
manifold passage through the
turbocharger mounting flange. This
is to prevent chips from entering the
manifold while drilling and tapping.
The cummins ISc engine uses
a divided exhaust manifold and
turbocharger. The thermocouple
must be installed to sample exhaust
temperature in the rear exhaust
passage (toward the flywheel).
9.
Drill through the exhaust
manifold into the rear passage at
the location shown in Figure 1. Use
a
7 ⁄
16
” drill, keeping the drill perpen-
dicular to the manifold surface.
