INTRODUCTION

The Air-Weigh Steer Axle Deflection Sensor is a major
component of several Air-Weigh Tractor/Truck Scale kits.
Properly installed, it allows the user to determine the weight
on a spring-ride steer axle.

For the most accurate weighing, follow the installation
procedures in this guide exactly.

See the user manual included with your kit for
complete scale installation, calibration and operation.

You must have the ComLink and display installed
and powered to be able to check A/D readings using
the DIAGNOSTICS menu in the display. Alternately,
you can also use the optional Field Deflection
Sensor Tester to get measurements directly at the
sensor.

Do not move the vehicle until after alignment tool

removal, Step #19.

Following sensor installation, do not calibrate

until after the vehicle has been in normal operation
for a week or 800 miles, whichever comes first. This
allows for a break-in period for the sensor. Do not
operate the vehicle with the alignment tool in place.

The heavy calibration must be done using a
maximum vehicle load.

Deflection Sensor Test Device, Air-Weigh PN 1000

The Field Deflection Sensor Tester, Air-Weigh P/N 1000,
can be used to measure A/D readings of the deflection
sensor without connection to the AW5801 Truck Scale
Comlink.

NOTE: A/D refers to the analog-to-digital conversion of the

sensor reading.

SENSOR INSTALLATION OVERVIEW

Welded Install
Note: Welding is the preferred method of installing

the deflection sensor brackets.

The following instructions are applicable to all steer deflection
sensor installs where the sensor brackets will be welded to the
steer axle. The balance of the install should be completed per
user’s manual included with your kit.

Material Needed

Alcohol or degreaser
Small grinder or sand paper
C-clamp
ARC or wire welder
Epoxy paint

A. Prepare Axle for welding and bracket placement

1. Clean center of axle in preparation for sensor bracket
placement.

a) Measure and mark center of axle.
b) Clean axle on both sides of the center mark in an

area wide enough to encompass brackets.

1) Use alcohol or degreaser to remove grease.

2) Sand off any paint in the area.

2. If not already assembled, attach alignment tool to the
two brackets

3. Remove foam strip from the bottom of bracket (weld
only).

4. Center bracket on axle

5. Use C-clamps to hold bracket in place.

8

6. Weld bracket (see Step B). Allow to cool before
removing clamps and alignment tool.

7. Apply epoxy paint to welded area; let dry before
proceeding with sensor mounting.

B. Weld Bracket

1. Weld a full bead on front and back of each bracket
piece.

2. Allow to cool before removing clamps and alignment
tool.

3. Do not operate vehicle with alignment tool in place.

9

Glue Install – alternative to welding

Mark the center of the axle and prepare it for glue.
Apply glue to the bottom of the bracket assembly.
Mount bracket assembly on the axle with band clamps.
Tighten the band clamps and let the glue cure.
Apply epoxy paint to glue and axle seam, let dry.
Mount the sensor and mounting tab to the brackets.
Connect the cables and mount to the tab.
Route the extension cable through the firewall.
Check for sensor readings in range.
Mount the cover over the sensor and brackets.
