11. Turn the sleeve over and let the key sleeve drop out.
12. Using a small rod or similar object (your hex key or the back of a ballpoint pen
should be sufficient), push the guide bushing assembly out of the sleeve.
Step 4: Reassemble the actuator
1. Lubricate the O-ring for the guide bushing assembly and press the guide bushing
assembly into the sleeve.
2. Drop the key sleeve back into the sleeve.
3. Using the shaft, turn the key sleeve around until it drops completely into place.
4. Place one of the bearing and race sets on top of the key sleeve (in the order of race-
bearing-race). Press firmly into place.
5. Put the remaining lubricant provided on the threads of the shaft.
6. Insert the shaft into the key sleeve.
7. Screw the nut down over the shaft.
8. Place the second bearing and race set over the nut. Press it into place.
9. Re-insert the snap ring.
10. Before replacing the knob onto the sleeve, stretch the JM wiper by pulling the edges
outward. This helps slip the knob over the sleeve.
11. Rotate the nut counter-clockwise until the shaft is fully extended. Slip the knob onto
the shaft and sleeve.
12. Hold the entire assembly so that the set-screw hole in the knob is facing you. Rotate
the actuator counter-clockwise until the hole in the knob lines up with the hole in the
nut.
13. Insert the set screw and tighten with an hex key. Do not let the assembly shift while
you are doing this or you will lose your alignment.
