Installing the Transducer
Attaching Anti-rotate Assemblies
1. Since the bracket is unique to each vehicle the anti-rotate bracket must be
provided by the customer. The following are guidelines for manufacturing
and locating the bracket. See the next two figures.
• The anti-rotate must move appropriately with the wheel of the vehicle
without relative motion between the wheel and the vehicle mounting
position. Alignment must be maintained to ensure that there is no
preload or forces on the slip ring due to suspension travel.
• The bracket must be stiff, preferably steel or stiff stainless steel tubing,
so as not to move or rotate when connected to an unsprung mass or
spindle, which will allow the slip ring assembly to move with the tire as
the vehicle is moving or testing.
• The bracket must be positioned so as not to hit the fender or other body
parts at the extreme end of the suspension travel.
• The bracket must maintain a minimum clearance from the tire so as not
to hit the tire when it is loaded and rotating.
2. For front wheel configurations (see the next figure):
A. Attach the anti-rotate bracket to an unsprung mass (such as the wheel
brake cylinder mount) which will move with the slip ring as the ATV is
moving or testing. Existing fasteners may have to be adjusted for
length.
Torque the fasteners as specified by the ATV manufacturer.
B. Secure the tubing, with the hinged anti-rotate bracket, in the anti-rotate
bracket.
C. Bend the tubing over the tire in the manner shown in the next figure
until the holes in the hinge assembly remain nearly lined up with the
mounting holes in the slip ring when let go of the tube.
Note A large offset between the hinge assembly and the slip ring can cause a
constant side load on the slip ring that can shorten the life of the slip ring
bearings.
D. Secure the hinge assembly to the slip ring using the two M4 fasteners
provided.
Before tightening the fasteners, check for obstructions. Load the
suspension and turn the steering fully in both directions several times
to ensure the tube does not contact any part of the wheel, suspension, or
body. Make adjustment as necessary.
Torque the two M4 fasteners in the slip ring to 3.2 N•m (2.4 lbf•ft).
Torque the eight 10-24 UNC fasteners in the anti-rotate bracket to 5.3
N•m (3.9 lbf•ft).
