1 Rotate the motor shaft until a (gear/target)
tooth is centered in the speed sensor port. If
this is not done, the sensor may be damaged
during the operation of the motor.
2 Make sure the lock nut and its threads are
clean and dry for the proper torque. Position
the lock nut against the alignment nut as
shown in Figure 22.
3 Move the washer and the o-ring up against
the speed sensor body threads as shown in
Figure 22.
4 By hand, lightly thread the speed sensor
body into the housing until the sensor
touches against the motor (gear/target) tooth.
Do not force the sensor against the (gear/
target) tooth, damage may occur. Make sure
the o-ring or the washer do not touch the
housing — see Figure 23.
5 Turn the speed sensor body out one quarter
turn (CCW) plus the additional amount (CCW)
needed to make the alignment notches
perpendicular to the motor shaft centerline
(90
°
+/-5 degrees from the motor shaft
centerline — Figure 24 and 25).
6 Maintain the speed sensor body alignment
(Figure 25), and tighten the lock nut to 8,5-14
Nm [75-125 lb-in.] (torque values are for
clean dry threads).
7 Check the speed sensor body for correct
alignment (Figure 25), reinstall the sensor if it
is not correct.
