B4 VERTICAL ALIGNMENT USING AN INCLINOMETER
B4.1 Tools Needed: A digital inclinometer, Torx T-20 screwdriver. (If a clip from the Bendix Alignment Tool kit is
available, the clip may be placed over the front of the radar sensor during this process.)
B4.2 Park the vehicle on a level fl oor. Air suspensions must be charged and stable.
B4.3 Calibrate (or "zero") the inclinometer on a horizontal section of the frame rail. Follow the manufacturer's
instructions (typically digital inclinometers have a "SET" button for this purpose).
B4.4 Place the calibrated digital inclinometer against the front surface of the radar, so that the tool is held in the
same direction as it was on the rail. With the digital inclinometer resting as shown, verify that the
display shows 0° (± 1.5°) from vertical, when measured by an inclinometer set to zero on the vehicle's frame.
NOTE: Complete the steps below only if a vertical adjustment is necessary.
B4.5 Use the Torx T-20 screwdriver to turn by hand the top-left adjustment stand-off. During the adjustment, observe
the digital display on the inclinometer and turn the vertical alignment screw clockwise or counterclockwise
depending on the vertical direction (up or down) needed, until the reading is zero degrees.
B4.6
The radar is aligned vertically when the display is between -1.5° and 1.5°, however to achieve a more
precise alignment, adjust the vertical alignment screw until the digital alignment value is near zero (0°).
Note: The alignment process shown here is for Bendix alignment brackets. For other brackets, similar alignment
steps will be needed; consult the vehicle manual for full instructions.
B4.7 If used, be sure to remove the clip before returning the vehicle to service.
