About LoadMaxx for Hendrickson
Suspensions
LoadMaxx is a weighing system for vehicles that works by using
that number into weight, which is displayed in the truck cab. Weight
information, including axle group, net, and gross vehicle weights, is

Note: This section applies only to scales using the 5817
skip
this section and see the section on installing the drive axle sensor
(page 6).
Preparing the Steer Axle Sensor Brackets
1. Locate and mark the center of the steer axle.
2. Using chalk or a permanent marker, mark the top of the
total). Clean this area. If the axle is heavily caked with dirt
or grease, use a degreaser such as Brakleen to remove the
worst.
3. Using 40-grit medium sandpaper or a pneumatic grinder,
sand the 6-inch area until nothing remains but bare metal.
We recommend that you partially grind down the mold line as
well.

and that no axle paint is left under the pad. If there is any
paint at all that will be touching the brackets, sand until it has
been removed.
6. Once you have prepared the axle, place the bracket
rocking in any direction. If the bracket rocks, sand or grind off
Note: Make sure that the main body of the bracket does not touch
the axle. Only the feet of the bracket should touch the axle.

Adding a Protective Spray Paint Coating
To prevent steer axle corrosion, we recommend you spray paint
around the base of the bracket.
1. Using any enamel-based spray paint, paint around the base
of the bracket and over the welded section. Paint all bare
metal around the bracket completely.
2. Once the paint is dry, we recommend that you paint all
exposed metal a second time.
Spray Paint Coating
3. Fillet weld a full bead on the front and back edges of each
of the bracket, only the edges indicated below. Air-Weigh
recommends that you use equipment similar to Miller
Shopmaster 300 AC/DC; AMP/VOLT setting of 22; wire
speed of 3.5; and a welding argon gas mixture of 75/25. MIG
the same settings as the Miller Shopmaster noted above.
