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)

.
