Banks Power Cummins Motorhomes: (Diesel ’93 - 98 B5.9L & C8.3L) Power Systems- Stinger system 8.3L, 250-325-hp rated Class-A Pusher MH - Manual (Page 2)

PREPARATION AND PRECAUTIONS
For ease of installation of your Banks Stinger
system, familiarize yourself with the procedure by
reading the entire manual before starting work. This
instruction manual contains 12 pages of text, illustrations
and parts listing. If any pages are missing, please call
GALE BANKS ENGINEERING for a replacement.
Throughout this manual, the left-side of the vehicle
refers to the driver’s side, and the right-side to the
passenger’s side.
This Banks system is designed to fit Class-A Cummins
powered pusher motorhomes equipped with the
C8.3L engine with a factory horsepower rating of 250,
275, 300 or 325. For further identification, check the CPL
number on the engine information tag located on the timing
cover. This manual applies to CPL’s 1406, 2102 and 2103.
Disconnect the ground cable from the battery
before beginning work. If there are two batteries,
disconnect both.
Route and tie wires and hoses a minimum of 6
inches away from exhaust heat, moving parts and
sharp edges. Clearance of 8 inches or more is
recommended where possible.
During installation, keep the work area clean. If
foreign debris is transferred to any Banks PowerPack
component, clean it thoroughly before installing.
Cleanliness is also important on and around the engine.
Because diesel pushers tend to gather a large amount of
grease and dirt in the engine compartment, steam cleaning
the engine prior to the Stinger installation is recommended.

TURBOCHARGER REMOVAL
Position vehicle on a flat level surface.
Disconnect the air inlet elbow or inlet hose from the
compressor inlet of 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 (EXHAUST TEMP.) GAUGE
The exhaust gas pyrometer monitors the temperature
of the exhaust entering the turbocharger turbine
housing. Installation requires that the exhaust manifold be
drilled adjacent to the temperature probe 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.
