PARTS REQUIRED
These parts are included in the 510-RK (Retail Kit) products and are sold separately in the 101-SK kit:
| 1/8” Female NPT to 1/4” Tube Fitting
Straight or elbow configuration, to connect the air line to the back of the
gauge
---|---
| Street Tee Fitting
The thread size and type should match the thread size and type of the vehicle
suspension
| Male NPT to 1/4” Tube Fitting
The thread size and type should match the thread size and type of the vehicle
suspension
| 1/4” Air Line
The amount of air line needed depends on the mounting location of the gauge
SPECIFICATIONS & OVERVIEW
The 510 series is designed for use on an air suspension axle group with one
height control valve. Within this series, there are different products designed
for different axle group configurations.
Before installation, make sure you have the correct gauge for your
application:
| Suspension | 510-30 | Gauge – Kilograms (KGS) |
|---|---|---|
| Single Axle | 510-46 | 510-16KG |
| Tandem Axle | Unavailable | 510-21KG |
| Tri Axle | Gauge – Pounds (LBS) | 510-25KG |
If you have the wrong gauge for your application, please call our technical support listed on page 2.
TWO HEIGHT CONTROL VALVES:
If your axle group has two Height Control Valves (HCVs), then you will need a dual leveling valve toggle switch sold separately (PN: 919-MINI-M3). This will allow the gauge to connect to both of the separate air systems and give you an accurate weight reading for the axle group
SCALE INSTALLATION
The 510 series scale is designed to be mounted inside the vehicle cabin, it is not for outdoor use. The following steps will walk you through how to correctly install the gauge.
-
CHOOSE MOUNTING LOCATION
The gauge can be mounted in the dash panel either using an existing factory gauge hole or by creating one. If this option is unavailable or not desirable, Right Weigh has an optional bracket (510-B-BR or 510-C-BR) that can be purchased separately to mount the gauge. See below for a detailed list of options for mounting into the dash:
a .Use an available 21/16” (52mm) factory gauge hole. b. Remove and replace a factory installed air suspension pressure gauge. c. Cut a new hole in the dash panel using a 21/16” (52mm) hole saw as shown. Make sure to check behind the dash panel for internal wires and components that may need to be moved to avoid damage.
d. Use Right Weigh 510-B-BR or 510-C-BR bracket or an aftermarket bracket to mount the gauge. -
DUMP AIR FROM SUSPENSION SYSTEM
-
CONNECT AIR LINE TO GAUGE
If replacing a factory installed air suspenson pressure gauge, connect the existing air line to the Right Weigh gauge and skip ahead to Step 7.
Otherwise, route a new air line through the gauge cutout and connect to the back of the Right Weigh gauge using the appropriate fitting. -
ROUTE NEW AIR LINE TO SUSPENSION
-
INSTALL TEE FITTING IN AIR BAG
Remove the suspension air line fitting from the top of one of the air bags.
Insert a street tee fitting into the top of the air bag that matches the thread size. Reinstall the suspension air line and fitting into the street tee. -
CONNECT NEW AIR LINE TO TEE FITTING
Connect the new 1/4” air line to the remaining port on the tee using the male NPT tube fitting. -
CONNECT TO POWER AND GROUND
Connect the gauge wiring harness to power and ground. Be sure the RED wire is connected to a SWITCHED positive (+) power source and the BLACK wire to chassis ground (-). Supply voltage must be between 9 and 32 volts DC. DO NOT wire the gauge to the instrument cluster dimmer circuit. The dimmer control may disrupt the color changing back light and cause it to malfunction.8 -
MOUNT GAUGE
Use the U-bracket and hardware provided to mount the gauge to the dash panel or bracket. -
AIR UP SUSPENSION SYSTEM TO CHECK FOR LEAKS
CALIBRATION AND OPERATION
CALIBRATING
- The vehicle must be fully loaded. For best results, calibrate with a loaded weight within 1500lbs or 750kgs of your typical axle group weight (DO NOT calibrate empty!)
- Using a certified in-ground scale, obtain a loaded weight for the axle group attached to the gauge.
- Park on a level surface. Shift the transmission to neutral and set the parking brakes.
- Chock the wheels to prevent unexpected vehicle movement.
- Release the parking brakes.
- Make sure the Height Control Valve (HCV) has fully inflated the air bags. If needed, briefly dump the air from the suspension and allow the HCV to refill the system.
- Using a flathead screwdriver, turn the calibration screw on the dial face until the gauge matches the certified axle group weight.
OPERATING AND WEIGHING
- Park on a level surface. Shift the transmission to neutral and set the parking brakes.
- Chock the wheels to prevent unexpected vehicle movement. Release the parking brakes.
- Make sure the Height Control Valve (HCV) has fully inflated the air bags. If needed, briefly dump the air from the suspension and allow the HCV to refill the system.
- View the load scale to determine the on-the-ground axle group weight.
TROUBLESHOOTING
PROBLEM WITH THE GAUGE?
Below is a list of problems we have seen with a simple fix. If you don’t see
your problem listed here or our troubleshooting doesn’t fix your problem, call
Right Weigh Tech Support listed on page 2 for further assistance!
ERRATIC / INACCURATE READINGS
The vehicle is not parked on a level surface:
Parking on sloped or banked surfaces will cause the vehicle weight
distribution to shift between the axle groups.
The vehicle’s brakes are on:
When the vehicle brakes are set, they could apply additional pressure or
torque on the suspension airbags. This will cause the suspension to have a
different air pressure than what is actually needed to hold up the weight.
The vehicle is parked on an uneven or rough surface:
If one or more of the vehicle’s wheels are in a pothole, that could result in
additional pressure or torque on the suspension airbags. This will cause the
suspension to have a different air pressure than what is actually needed to
hold up the weight.
There is a significant air leak in the suspension system:
This could cause the HCV to refill the suspension in intervals to maintain the
vehicle’s ride height. If there is a significant leak, the gauge display will
slowly decrease in value and then quickly increase in value when the HCV
refills the suspension system.
The Height Control Valve (HCV) is malfunctioning or broken:
If the HCV is not functioning correctly, the air pressure applied to the
suspension system could be inconsistent and/or erratic. To test for an HCV
problem, acquire a weight reading from the Right Weigh gauge and write it down
(refer to gauge operating instructions for proper procedure). Drive the
vehicle around the block and return to the same location. Acquire a second
reading from the Right Weigh gauge. If the two readings are significantly
different, then the HCV might be malfunctioning.
