TORQUETUBE INSTALL
1.
With the motorhome safely raised,
ground wire(s) disconnected, and
precautions in place, remove the
factory exhaust system.
2.
To provide better access to
the manifolds remove the front
wheels from the motorhome. If the
motorhome is equipped with inner
front fender shields, remove them for
improved access.
Note: Before removing the lug nuts,
make sure a capable torque wrench is
available to tighten the lug nuts to the
manufacturer’s torque specifications
3.
The vehicle may have a bolted in
crossmember between the leveling
jacks at the front of the vehicle.
This will need to be removed prior
to removing the factory exhaust
system and reinstalled after the Banks
PowerPack system is place.
WARNING: Do not use the leveling
jacks while the cross-member is
removed.
4.
Locate the oxygen sensors in the
exhaust headpipes on each side of
the engine, forward of the catalytic
converters. Unplug the connectors and
unscrew the oxygen sensors, keeping
track of the left and right sensors. Be
careful not to touch or contaminate
the sensor.
5.
Remove the factory hardware on
the front 2-bolt headpipe flanges.
6.
Disconnect the four (4) bolt flange
at the front of the catalytic converter.
Remove the factory Y-pipe from the
vehicle. Retain the factory hardware
for reassembly.
Note: Whenever possible, it is
recommended that the catalytic
converters be inspected. Restricted
or damaged catalytic converters can
impede performance of your Banks
PowerPack.
7.
Pull out the dipstick and remove
the small bolt that attaches the oil
dipstick tube to the cylinder head.
At the front of the vehicle, behind
the front engine cover, remove the 2
screws that retain the dipstick tube to
the radiator support. Near the exhaust
manifold, pull the dipstick tube up out
of the engine block. Check to see if
there is an O-ring on the tube. If not,
the O-ring may be stuck inside the
hole in the engine block. This O-ring
should be retrieved if necessary and
placed back onto the tube before
reinstalling it. Accessing the dipstick
may be easier from the interior engine
cover (doghouse).
8.
To remove the exhaust manifolds,
use a wrench or socket to back the
nuts away from the manifolds at least
one turn, then use a 5mm 6 point
socket to remove each stud from
the head. As an alternate method,
take the nuts off the studs, and then
remove the studs.
9.
After the manifolds have been
removed from the vehicle, remove
any remaining studs from the heads.
The studs must be removed from the
heads in order to install the Banks
TorqueTubes.
10.
On the passenger side of the
engine, loosen the three rearmost
outside valve cover bolts. Slide the
valve cover heat shield provided under
the heads of the bolts and tighten. See
Figure 2.
11.
On some vehicles a wire loom
bundle runs along the top of the frame
rail adjacent to the side of the engine.
In these instances this loom and any
other wiring must be relocated away
from the TorqueTube heat area. Pry
the wire loom clips from the frame
rail to provide enough slack in the
