Installation Instructions

7. 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 6 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 CBXA 40 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 in the air
reservoir
(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 spring
pressure required for varying load capacities
(Figure 11)
.
Optional Air Release System
If your CBXA 40 was ordered with a slider pull pin air release
system, the air release control valve and the actuator will
need to be plumbed
(Figure 11.A)
.
Optional PosiLok
™
System
If your CBXA 40 was ordered with a PosiLok
™
anti-dock
walk system, the PosiLok
™
actuator will need to be plumbed
(Figure 11.B)
