4. OPERATION INFORMATION
4.1 Adjusting Wheel Adaptor 175-285-1 Lock Lever
The wheel adaptor lock lever should not contact the wheel adaptor center casting before
the sensor shaft is tightly secured. An adjustment can be made to the lock lever
assembly to restore its full tightening capability.
Turn the adjusting thumbscrew to adjust the lock lever adjustment screw as illustrated
below (do not remove the assembly). With the sensor fully seated in the adaptor and firm
hand force applied to the lock lever, adjust the lock lever screw from the bottom side of
the center casting so the lever will stop approximately 30° short of contacting the center
casting.

NOTE: Normal manufacturing variations will allow the clearance
between the lever and casting to change if different sensors are
mounted to a given adaptor. This variation is acceptable if the
lever has enough travel to fully tighten the lock onto the shaft.
