general installation practices
installation instructions
1.
remove engine cover “dog house.” remove
air filter cover. remove rubber air inlet hose
assembly from air filter housing and throttle body
on engine. cover throttle opening to prevent
foreign objects from entering engine.
2.
remove sparkplug wires from sparkplugs.
label wires for reinstallation if not familiar
with firing order. lay sparkplug wires away from
exhaust manifolds. now remove sparkplugs from
engine.
3.
remove muffler and tailpipes from vehicle.
if this assembly extends over the rear axle,
cutting off the tailpipes will allow the muffler/
tailpipe assembly to be removed more quickly.
heat from a torch will most likely be required to
separate slip joints. to remove the exhaust system
from the rubber hangers, squirt some wd-40,
silicone spray or similar lubricant onto the lower
end of the rubber hangers, where the hanger rod
protrudes through the rubber, then use a pry bar
to pop the rubber hangers off the rod.
4.
remove the intermediate pipe from between
the muffler and catalytic converter. this will
be a short stub adapter on short wheelbase
models, or a pipe, or pipe with hanger on longer
wheelbase models. heat the catalytic converter
slip joint as required to remove the pipe.
5.
disconnect the oxygen sensor plug where
oxygen sensor wires join the wire loom (not
at the oxygen sensor). carefully unscrew the
oxygen sensor from the exhaust y-pipe. do not
use any penetrating oil or lubricants to assist with
unscrewing the oxygen sensor, as chemicals can
permanently damage the sensor.
6.
separate the catalytic converter from the
y-pipe assembly and the air injection
tubing. use heat at slip joints as required. remove
y-pipe assembly by unbolting flanges at exhaust
manifolds.
7.
on vehicle models with air injection into the
exhaust manifolds, unbolt the air injection
tube from the rear of the right exhaust manifold.
penetrating oil may be necessary for bolt removal.
8.
unbolt dipstick tube from left exhaust
manifold. disconnect air injection tube (if
equipped) and egr tube from fittings on rear and
bottom of left exhaust manifold. use penetrating
oil as required.
NOTE: Unscrew tubing nut from fittings on exhaust
manifold, do not attempt to remove the adapter fittings
from the manifold. In extreme cases, heat from a torch
may be required to loosen the tube nuts. Heat the nut
to a dull red color, let it cool, then spray the nut with
penetrating oil and attempt to loosen the tube nut. DO
for ease of installation and trouble-free
operation of your banks powerpack, please
read this entire 14-page instruction package
before starting any work. (if any pages are
missing from this package, please call gale banks
engineering immediately for a replacement.) become
thoroughly familiar with all components and phases of
the installation and determine what additional tools or
materials you may need to complete the installation.
inspect all components supplied for any foreign
material that may have entered during shipping
and handling.
WARNING: whatever methods are used
to elevate the vehicle must be of sufficient
capacity for the vehicle weight involved. NEVER work
under any vehicle supported only by a jack of
any kind. DO NOT USE concrete blocks or other
masonry items that may collapse under the
vehicle weight.
pay particular attention to the routing of any
wires. keep them away from exhaust heat,
moving parts and sharp edges that may cause cuts or
other damage. route or tie wires away from critical
areas as required. keep all wires a minimum of 6”
from hot exhaust parts, 8” or more is recommended
whenever possible.
right-hand and left-hand designations refer to
the driver’s right or left, as seated in the vehicle,
(i.e.: right-hand refers to the passenger side of the
vehicle, unless noted otherwise.)
the banks motorhome powerpack, is designed
to fit class-c 460 ford chassis platform engine/
chassis combinations. because of different equipment
layouts used by various coach builders, some
accessories and components may have to be relocated
to accommodate the air intake components of the
banks powerpack, or the powerpack components may
need to be modified.
