HOW IT WORKS

The sensor is mounted so that it compresses or extends as the axle bends. The change in length of the sensor is measured and converted to weight by the Right Weigh gauge after calibration.

The tension bar is a wear item, whose life span depends on environmental conditions and severity of use. Replacement of this part is included with your 3 year warranty, after which time it can be purchased separately.

INSTALLATION

WARNING!
Please refer to the corresponding Installation Overview for speciﬁc placement of sensors before beginning.
Please check your vehicle manufacturer’s recommendations regarding welding before beginning.

MARK THE CENTER OF THE AXLE
Use the tape measure to ﬁnd the centerof the axle and mark location with a marker. For walking beam installations, ﬁnd the point midway between the pivot point (center of the equalizing beam) and the attachment point of the axle. Please refer to corresponding Installation Overview for speciﬁc placement of sensors. The sensor must be placed on the TOP of the axle
MARK MOUNTING BLOCK LOCATIONS
Place the Welding Jig Assembly on the axle so that it is centered over the line. Draw circles around each mouting block to mark their location on the axle. Remove the jig from the axle when ﬁnishd.
PREP AXLE FOR WELDING
Use the angle grinder or sanderto clean the metal in the circlesto be welded. Make sure the area is free of paint, dirt, rust, and any other debris.
POSITION WELDING JIG ON AXLE
Position the Welding Jig Assembly onto the axle, centering the jig on the axle centerline. Use a chain of 11” zip ties to hold it in place during welding. CHECK VEHICLE MANUFACTURER’S RECOMMENDATIONS REGARDING WELDING BEFORE BEGINNING.
WELD BLOCKS TO AXLE
Weld the blocks to the axle in order shown.
Tip: Make sure to weld with a bead that is the width of the block.
ALLOW BLOCKS TO COOL
REMOVE ALIGNMENT DOWEL
Cut the zip ties and loosen the mouting block bolts to remove the alignment dowel.
PAINT BLOCKS AND AXLE
Paint the axle tube and blocks to prevent rust. Mask oﬀ the holes in the blocks to prevent over spray.
INSTALL TENSION BAR
Carefully install the tension bar into the mouting blocks.
TIGHTEN MOUNTING BLOCK BOLTS
Tighten both mounting block bolts to clamp the tension bar in place. Torque each bolt to 10 ft-lbs.
INSTALL PICKUP COIL AND CLAMP
Install pickup coil over the tension bar so that the cable points in desired direction on the axle. Use the small hose clamp to clamp the pickup coil in place. Use a nut driver to tighten the clamp.
INSTALL METAL COVER
Center the cover over the tension bar assembly and secure in place using the large hose clamp. For best results torque the hose clamp to 80 in-lbs.
INSTALL LOOP CLAMP
Bend the loop clamp over the cable about 4” from the pickup coil.
Bolt the loop clamp to the metal cover as shown using the supplied bolt and washer.
CONNECT EXTENSION CABLE AND ROUTE TO GAUGE
Plug the extension cable into the mating connector on the pickup coil cable. Route the other end of the extenson cable to the gauge, using the included zip ties to secure the cable along the way. Connect the extension cable to the gauge using the supplied butt connectors. Seal the butt splice connection with the supplied heat shrink tubing. See gauge instructions for further details.
