2. Slide the take-off arm assembly onto the spline lever adapter
shaft. Insert the screw with star washer through the take-off
arm and add the second star washer and nut. Tighten nut with
socket so arm is lightly snug on the shaft but still able to rotate.
This will be tightened after linkage is correctly oriented.
3. Attach follower arm to positioner feedback shaft using the star
washer and 10-32 nut.
NOTE: The arm will point up when feedback shaft is in the free
position.
4. Using four ¼-20 x ½" bolts, fasten positioner to universal
bracket using appropriate hole pattern (stamped on bracket).
5. Using a ½" end wrench and two
5
⁄16-18 x ½" bolts, attach bracket
to actuator transfer case pad. Leave these bolts slightly loose
until final adjustments are made.
6. Rotate take-off arm so the follower pin will slide into the slot on
the take-off arm. Adjust the bracket position as needed noting
the engagement of the follower pin and the take-off arm slot.
The pin should extend approximately
1
⁄16" past the take-off arm.
When properly adjusted, securely tighten the bracketing bolts.
Orienting the Take-off Arm for Final Lock Down
1. Tube the Logix 3200MD positioner to the actuator according
to the instructions given in Section 5.4, “Tubing Positioner to
Actuator.”
2. With supply pressure off, rotate the follower arm in the same
direction the shaft would rotate upon a loss of supply pressure.
When the mechanical stop of the follower arm (positioner) is
reached, rotate back approximately 15 degrees.
3. Hold the take-off arm in place; tighten the screw of the take-off
arm.
