LEVELING SYSTEM

Hydraulic Leveling

The shock absorber by definition is a hydraulic device used to dampen
suspension/body movement. Road surface irregularities are compensated for
by the shock absorber. The roadmaster chassis incorporates the "Monroe"
shock in the design of the exclusive air glide suspension system. This shock
absorber is a telescopic, mono tube unit filled with nitrogen gas and
hydraulic oil. The result of the mixture is uninterrupted damping for the
smallest of wheel deflection.
By design, a self lubricating seal is used which will allow approximately
10% of the total oil capacity to pass onto the piston rod. The gradual process
of oil loss does not affect the performance of the shock absorber during the
service life. This process will be evident after a long period of service by an
oil film on the body of the shock absorber. The appearance of a coating or
film on the body or rod is completely normal, it is an indication the shock is
functioning normally.
Road holding, handling, balance and braking characteristics all can be
contributed to the shock absorber. The operating conditions for which the
shock absorber must endure will determine the life span. However, since the
only moving part is the piston rod, there are no springs, hinges or pins to
wear out, get weak or deteriorate.
The three point leveling system features a multiple warning system with
flashing lights and a bong alarm to alert you of the jack position. The system
also features a remote control location from the driver seat.
The model 22.5A J-II leveling system pump is located in the roadside
compartment behind the A/C condenser. The valve assembly manifold is
mounted on the pump motor, providing easy access to the manual retract
valves. The system is designed to be self bleeding in the event any
component of the hydraulics has been removed or repaired. Fully extend and
retract each jack twice. The remote rocker switches will operate with a
minimum of 7.5 Volt DC. Optimum requirements for operating the system
are voltages above 9.6 Volt DC.
CAUTION: Before leveling the motorhome survey the
area around and under the motorhome for obstructions
which can damage the motorhome or undercarriage
components when the air bags are deflated.
CAUTION: Hot asphalt may not support the weight
the is placed on the hydraulic jack pads. Place thick
plywood under the jack pads to help disperse the
weight. Never use the leveling system to support the
entire weight of the motorhome. Damage from excessive
torsional twists can result.
