30. Depending on feeder cup size, select three of:
116-019D SHAFT SENSOR MOUNT (“Large”)
116-020D SMALL CUP SENSOR MOUNT (“Small”)
31. Select three new:
801-199C SCR SELF TAP #10 X 3/4
With the slotted-hole break of the mount ( or )
down and to the rear, and the short break of the
mount up and to the front, secure the mount to the

Install Sensors
33. Select one new:
253100 LOUP SHAFT SENSOR 2&3 CHANNEL
If two plastic nuts are pre-installed, remove and
save one.
If the sensor may include a bracket not used in this
installation. Remove it.
34. If no plastic nuts are pre-installed on the
sensor , select two new:
710425 NUT HEX JAM, PLASTIC M16 X 2
Thread one jam nut onto the sensor .
35. Insert the flat faced end of the sensor through the
slotted hole in the mount ( or ). Thread the
second jam nut onto the sensor.
36. Check that the drive shaft is rotated so that the
magnet face is parallel to the sensor face.
37. Adjust the jam nuts so that the gap between the
sensor face and the magnet face is:
1 ⁄
8
inch (3.2 mm)
Note: If the gap is too small, the edge of the magnet, or
the cable ties, may strike the sensor as the shaft
rotates. If the gap is too large, the sensor may fail
to detect shaft rotation.
38. Rotate the shaft to verify clearance. Set the seed
rate handle to 0 and check clearance again. Set the
seed rate handle to 100 and check clearance.
39. Tighten the jam nuts. Do not over-tighten.
40. Repeat step 33 through step 39 for each sensor
position.
