CAUTION: When mounting sensors to the wheel adaptors, the sensor shaft
must be fully seated. Make certain that there is no play or
looseness between the sensor shaft and the wheel adaptor.
Rotate the wheel while holding the sensor. Listen and feel for
movement between the sensor and wheel adaptor. Runout
compensation and alignment accuracy will be adversely affected
if there is any movement between the sensor and wheel adaptor.
Sensors must fit tightly against the surface of the wheel adaptor
or the lock may not hold. This could allow the sensor to fall and
be damaged.
When the sensor is mounted, the sensor locking lever should be rotated using firm hand
pressure. Tools should not be used to force the locking lever. If the lever can be rotated
until it contacts the casting and is not fully locked, refer to “Adjusting Wheel Adaptor Lock
Lever” on page 23.
