When To Use It
Use the exhaust brake when traveling down
a hill, on the freeway or exiting the off ramp.
When activated, the exhaust brake will help
control road speed or sufciently slow the
road speed until the Allison Transmission can
automatically downshift to the next lower
gear. Downshifting automatically occurs from
high gear down to second gear. Certain road
conditions and engine speeds may require the
transmission be manually shifted down in order
to generate adequate engine RPM and increase
the exhaust brake effect.
Cruise Control
Turning on the exhaust brake switch DOES
NOT cancel cruise control.
If cruise control is engaged, tap the service
brake pedal to disable cruise control. Turn the
exhaust brake switch on and the exhaust brake
will activate.
Another way to disable cruise control is to turn
the cruise control power switch off. The exhaust
brake switch can then be turned on to activate
the exhaust brake.
WARNING:
The exhaust brake is designed to assist
the service brakes. The exhaust brake
WILL NOT bring the motorhome to a
stop. Refer to the engine OEM manual
for more information.
NOTE:
Use of the exhaust brake can help
increase the life of the service brakes.
Alignment
Camber:
Camber, as shown, is vertical tilt of wheel as
viewed from the front of the motorhome. This is
machined into the axle when manufactured and
is not adjustable.
“Positive” camber is an outward tilt of
the wheel at the top.
“Negative” camber is an inward tilt of
the wheel at the top.
Toe Setting:
The toe setting represents different distances
between the front and rear of the tires (measured
at the vertical center line of the tires).
Toe-in: Occurs when the tire front distance is
less than the tire rear distance.
Toe-out: Occurs when the tire front distance is
greater than the tire rear distance.
Wheels are generally set with initial toe-in.
As the motorhome operates tires tend toward
a toe-out condition. By starting with an initial
toe-in setting, a desirable “near zero toe-in” can
be achieved when the motorhome is in motion.
Incorrect toe settings, where toed-in or toed-
out, can have a signicant affect on tire wear.
The toe setting is adjusted by lengthening or
shortening the cross tube.
