Installation
2. Attach the wheel/transducer to the test vehicle.
Installing the lug bolts directly against the transducer face, without the anti-
galling compound and the shim washers, can cause galling of the
transducer face.
Galling of the transducer face can result in uneven torquing (and possible
over-torquing) of the lug bolts.
To prevent galling, always use the shim washers provided. Always lubricate the
bolts and shim washers as described below.
Lubricate the lug bolt threads, under the bolt head, and both faces of the
shim washers with the Nikal based anti-galling compound.
Tighten the lug nuts in three increments up to the specified torque, in the
sequence shown in the next figure to the torque rating recommended for the
wheel.
Important Do not exceed maximum specified lug-nut torque.

The anti-rotate arm must be
long enough to accommodate
vehicle suspension travel.
If the anti-rotate bracket is
fender or trailer-mounted, it
must be in a vertical orientation
so that when suspension travel
occurs, the anti-rotate are does
not rotate and cause errors in
the data or bend the rod.
Ensure bracket will not hit
body parts during vehicle
testing or suspension travel.
For dual or nonsteering axles, the
anti-rotate arm must be
mounted to the unsprung mass
or suspension, or possibly the
fender or trailer (less desirable).
If the arm is mounted to the
fender or trailer, the assembly
must have a close-fitting hole
that will accommodate the
suspension travel.
The bracket can be attached to
the brake caliper if the wheel
hub assembly is equipped with
a disc braking system.
