Banks Power Cummins Motorhomes: (Diesel ’93 - 98 B5.9L & C8.3L) PowerPack & Stinger systems w_Twin Ram Manifold 5.9L, 190-210-230-hp rated - Manual (Page 4)

For TwinRam installation only, proceed to
step 51.
TURBOCHARGER REMOVAL
position vehicle on a flat level surface.
Disconnect the air inlet tube from the air
cleaner and the inlet to the turbocharger.
disconnect the exhaust pipe from the rear of the
turbocharger.
remove the two oil drain tube bolts from
the turbocharger.
Disconnect the oil supply hose at the
turbocharger.
note the orientation of the compressor
housing in the vehicle. When the new
assembly is installed the orientation of the
compressor outlet should remain the same.
remove the boost pressure hose from the
nipple of the wastegate actuator. 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.
clean and inspect the exhaust flange
mounting surfaces on the exhaust manifold.
remove any remaining gasket material from the
turbocharger oil drain flange surface. Make sure
the surface is clean and dry.
PYROMETER PROBE INSTALLATION
The exhaust gas pyrometer monitors the
temperature of the exhaust entering the
turbocharger turbine housing. installation requires
that the exhaust manifold be drilled near the outlet
of the manifold adjacent to the turbine housing. For
this reason it is essential that the turbocharger be
removed from the engine in order to clean out any
metal chips from drilling that could cause turbine
blade damage.
The cummins 6bT engine uses a divided
exhaust manifold and turbocharger. The
pyrometer probe must be installed to sample
exhaust temperature in one of the two exhaust
passages. Typically the exhaust temperature will
not differ appreciably between the two passages.
We recommend installing the probe in the rear
manifold passage to simplify routing the probe
wiring.
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.
drill through the exhaust manifold into the rear
passage at the location shown in Figure 1 . use
a 7 ⁄
16
-inch drill, keeping the drill perpendicular to the
manifold surface.
