TORQUETUBE INSTALL

With the motorhome safely raised,

ground wire(s) disconnected, and

precautions in place, remove the

factory exhaust system.

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

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.

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.

Remove the factory hardware on

the front 2-bolt headpipe flanges.

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.

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).

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.

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.

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
