Installation Instructions
7. Standard Air Control
System Installation
1. If NOT already present, 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 CBX69 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 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 may 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 your CBX69 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 CBX69 was ordered with a PosiLok
™
anti-dock walk
system, the PosiLok
™
actuator will need to be plumbed
(Figure 11.B)
.
