unit contacts motor or accessory. Also ensure that mating surfaces have not been damaged and that unit will fit squarely
on motor.
2.
Apply a thin layer of corrosion preventative or oil to motor facing and shaft to aid assembly and provide some corrosion
protection.
NOTE
Ensure there is no paint, burrs, protrusions, or deformations on the motor facing or
shaft. If the enclosure does not fit squarely on the motor facing, the alignment between
the sensor module and the magnetic pulse wheel may be degraded.

2.2.2 End-of-Shaft Pulse Wheel Installation
To prepare the pulse wheel assembly for installation, perform the following steps. See Figure 7 .
CAUTION!
Caution must be used when handling the pulse wheel assembly. The surface of the pulse wheel
outer rim is sensitive to scratches and impacts. The magnetic properties of the pulse wheel
material can also be distorted or erased by exposure to strong magnetic fields.
1.
Remove pulse wheel assembly from packaging.
2. Place one spacer washer into the shaft recess of the pulse wheel.
