Installing the Drive Axle Sensor Bracket Preparing the Camelback Suspension 1. Locate and mark the top center of the trunnion tube. Marking Center of Trunnion Tube 2. Using chalk or permanent marker, mark the top of the trunnion tube 3-3/8 in. (85.725mm) on both sides of the center mark. The overall measurement is 6-3/4 in. (171.45 mm). 3. -
Page 12: Welding The Bracket
Welding the Bracket 1. Place the mounting bracket assembly on the top center of the trunnion tube. Mark the center on the alignment tool and ensure it lines up with the center mark on the trunnion tube. 2. Use C clamps to hold the bracket in place. Make sure you leave the alignment tool in the bracket assembly while welding. -
Page 13: Adding A Protective Spray Paint Coating
Adding a Protective Spray Paint Coating 1. To prevent the drive axle brackets from delaminating due to corrosion, we recommend you spray paint around the base of the brackets. 2. Using any enamel-based spray paint, paint around the base of the bracket. Paint all bare metal around the bracket completely. -
Page 14: Routing Cables
Routing Cables 1. Route the 20’ steer extension cable and the 40’ drive extension cable along their respective axles and the frame, and then through the cab irewall. Leave enough length for sensor connections. If at all possible, route along an existing wire harness. Be careful to avoid routing along pieces of the frame that may move or cause wiring to rub. -
Page 15: Installing The Comlink And Display
Installing the ComLink and Display Preparing the Cab Display for Installation 1. Select a location for the display (1) on the dash panel (5) with at least 3” of clearance behind the dash panel (5) for the unit and its connections. A higher dash position provides better visibility. 2. Using a hole saw, cut a 2-1/8” hole (2) in the dash where you will mount the display. 3. Remove the hex nuts (4) from the studs (6) on the back of the display (1) to release the mounting bracket (3). Display Preperation and Installation Installing the Cab Display 1. Position the display (1) in the hole so that it appears level on the dash. -
Page 16: Mounting The Comlink
Mounting the ComLink 1. Select a location behind the dash for the ComLink module, ensuring there is adequate access to the scale and the electrical connections. 2. The ComLink module should be oriented with the connectors facing downward and installed by either one of the following methods, using the hardware provided: Use zip ties through the holes in the ComLink module mounting ears to secure it to any appropriate wire harness... -

Installing and Adjusting the Drive Axle Sensor 1. Remove the alignment tool from the brackets. Retain the nuts and bolts. 2. Insert the delection sensor into the brackets with its cable extending toward the side of the vehicle where you’ll route the sensor extension cable to the irewall. The engraved lettering on the sensor should face up. 3. Align the delection sensor with the bracket holes. -
Page 21: Setting A/D Values
A/D values. A/D refers to the analog-to-digital conversion of the sensor reading. This step will require the use of either the LoadMaxx in-dash display or the Delection Sensor Test box (P/N 1001). If using the LoadMaxx in-dash display, the scale must be installed and powered, and the Delection Sensor Extension Cable must be installed. -
Page 22: Adjusting The A/D Reading
3. Verify the A/D reading using the display in the cab (start the ignition to power on the display), or the delection sensor test box. If the reading is within range (750-1250), continue to instructions for the Final Sensor Torque. If the reading is not within range, follow the instructions to adjust the A/D readings below. Adjusting the A/D Reading If the A/D reading is above 1250, follow these instructions: 1. Loosen the nuts on both ends of the sensor 2. -
Page 23: Final Sensor Torque
If the A/D reading is below 750, or there is no A/D reading at all, follow the steps below: 1. Loosen the nuts on both ends of the sensor 2. At the plastic nut where the cable enters the sensor, exert UPWARD pressure with your ingers until the A/D reading is between 750 and 1250. Continue to apply pressure to maintain the desired A/D reading during the torque procedures in step 3. 3. -
Page 24: Cover Installation
Steer Axle Cover Installation 1. Mount the cover over the sensor and the brackets so that the sensor cable is completely under the cover. The sensor extension cable should emerge from the cover’s end port on whichever side you choose to route the cable. Ensure that the cable has free play and is not pinched by the sensor cover. - Page 25 Drive Axle Cover Installation 1. Locate the opening in the end of the cover. The opening is used for the sensor cable to go through. Cable Opening in Cover 2. Cut a notch in the supplied grommet and place it on the sensor cable.
- Page 26 3. Slide the sensor cable/grommet combination into the cover hole with the Molex connector of the sensor cable on the outside of the cover and set the Delection Sensor Cover over the sensor on the trunnion tube. Placing the Cable and Grommet into Cover 4. Slip each band clamp over the lange on the ends of the cover and tighten in place. Clamping the Cover to the Trunnion Tube Your Air-Weigh scale installation is now complete.
