11. 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 10 of this manual.
2. Install the air reservoir to the air reservoir brackets.
3. Plumb the air control system as illustrated (Figure 15).
The air control system of the CBX40/CB-4000 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 15).
IMPORTANT: The air 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 15).
Optional Air Release System
If your CBX40 Fusion/CBX40/CB-4000 was ordered with a slider
pull pin air release system, the air release control valve and
the actuator will need to be plumbed (Figure 15.A).
Optional PosiLok ™ System
If your CBX40Fusion/CBX40/CB-4000 was ordered with a
PosiLok
™ anti-dock walk system, the PosiLok ™ actuator will
need to be plumbed (Figure 15.B).
