When handling parts, wear appropriate gloves, eye-
glasses, ear protection, and other safety equipment.
Proper tightening of fasteners is important to the perfor-
mance and safety of the suspension. Follow all torque
specifications throughout the instructions.
4. SAFE WORKING PRACTICES
4.1
Air lines are pressurized and may blow debris, USE
EYE PROTECTION.
5. HCV INSTALLATION
5.1
Disconnect and remove old valve.
5.2
Attach the Link H00500 HCV to the same mounting
bracket. Or use the enclosed brackets as needed to
mount the valve.
1. Always mount valve with lever arm on the top side.
2. At full up or down suspension travel:
MAXIMUM LEVER ANGLE IS 45°
MINIMUM LEVER ANGLE IS 30°
3. Mount HCV parallel to frame rail
4. If NOT using the integral dump option, dump pilot
port vent must be left in place.
5. If using integral dump option, remove dump pilot
port vent and connect directly to 3-way selector
valve. Ensure that selector system is vented to at-
mosphere at all times (even when not being acti-
vated).
NOTE: Dump pilot port/system must not be
plugged at any time as this may affect valve center-
ing.
5.3
Attach the proper length lever to the H00500 HCV.
Check for any interference or straight lining of the valve
lever and linkage through the entire suspension travel.
5.4
Reconnect the air lines to the H00500 HCV per figure 1
on page 3. Connect the dump pilot port to a normally
closed control valve.
5.5
Adjust the ride height of the suspension utilizing the
H00500 HCV lever and the vehicle manufacturer’s ride
height recommendations. Install centering pin to ensure
the valve dead band is at ride height.
