Installation Instructions

5. Standard Air Control
System Installation
1. Install air reservoir, mud flap and stinger brackets. Grind
off paint and prepare all surfaces for welding. Refer to
welding standards detailed in Section 4 of this manual.
2. Install the air reservoir to the air reservoir brackets.
3. Plumb the air control system as illustrated
(Figure 11)
.
The air control system of the CBX slider suspension uses air
drawn from the tractor air system to pressurize the suspension’s
air springs. The suspension, working with the air control system,
provides optimum suspension performance only when all air
control system components are installed and operating properly.
IMPORTANT:
Make certain that all air lines and valves
are free from obstruction through the full
operational range of the suspension.
IMPORTANT:
A pressure protection valve (PPV) MUST
be attached to the air reservoir in order to
maintain proper air pressure
(Figure 11)
.
IMPORTANT:
The pressure protection valve maintains safe
brake pressure. Approximately 85 psig (5.9
bars) opens the valve, and 65 psig
(4.5 bars) closes the valve.
NOTE:
When installing pressure protection valve, use
a drop of oil or loctite
®
to lubricate threaded
connections. DO NOT use a pipe compound or
teflon tape as they could clog the valve.
A height control valve (HCV) is used to regulate the air
pressure required for varying load capacities
(Figure 11)
.
Optional Air Release System
If the CBX was ordered with a slider pull pin air release
system, the air release control valve and the actuator
will need to be plumbed. The Plumbing Diagram can be
obtained in the Air Release Pin Pull Mechanism Installation
and Operations Manual XL-AR452 Rev D, or contact SAF-
