2. MOUNTING SENSORS
2.1 Mounting Sensors Onto Wheel Adaptors
Sensors may be mounted on the wheel adaptors before mounting the wheel adaptors on
the vehicle. In some cases, it may be easier to mount the wheel adaptor first and then
mount the sensor onto the adaptor. Either method may be used.
Center the wheel adaptor center casting between the upper and lower castings. When
the center casting is properly centered, a plunger ball will fall into the detent position on
the adaptor rod.
Tighten both center casting lock knobs firmly. This will prevent the center casting from
slipping down when the sensor is attached.
CAUTION: Hand tighten center casting lock knobs as tight as possible (DO
NOT USE TOOLS TO TIGHTEN).
CAUTION: If the center casting lock knobs are not firmly tightened, runout
compensation and alignment accuracy will be adversely
affected.

If detached, attach the sensor to the wheel adaptor by inserting the sensor mounting
shaft (at the rear of the sensor) into the sensor mounting hole in the middle of the center
casting.
NOTE: The sensor shaft must be fully inserted into the sensor shaft
mounting hole.
