2.2. Wiring Harness / Controller Mounting Instructions
1. Begin by disconnecting the aircraft battery.
2. Select a mounting location for the autopilot controller.
2.1. Consider the overall mounting depth of the controller with pitot, static, and
electrical connections and allow clearance where necessary, especially
surrounding the moving yoke assembly.
2.2. Ensure that mounting location does not require autopilot servo lines to run
near com antenna coax.
2.3. Ensure that there is sufficient space near the autopilot controller to install the
Vizion Limitations Placard (Trutrak P/N 8300-092)
3. Remove the instrument panel and panel overlays as necessary.
4. Remove the seats.
5. Remove the left A-pillar and kick panel trim.
6. Remove carpeting.
7. Wiring harness routing.
7.1. Route the pitch (white) and roll (black) servo harnesses from the controller
to the left side of the panel.
7.2.Route the roll (black) servo harness up the left A pillar and out the leading
edge of the left wing as shown in Figure 2-1, Figure 2-2, and Figure 2-3.
Extend the excess harness out the inspection hole just forward of the

3.2. Cessna 182E-182T Roll Servo Mounting Instructions
NOTE: Apply torque seal to all bolts after final torquing is achieved.
1. The roll servo will be mounted in the left wing just forward of the inboard end of
the aileron.
1.1. Begin by removing the inspection cover on the lower wing skin located forward
of the inboard end of the aileron.
1.2. Figure 3-1shows the roll servo mounting location from below the left wing.
Figure 3-1
2. The Cessna 18X Upper Roll Bracket (P/N 1450-127) will be mounted to the flange
of the rear wing spar using 3 ea. AN526C-832R8 screws.
2.1. Locate the inboard screw hole as shown in Figure 3-2 on the upper wing skin.

2.2. Drill the inboard hole only at this time with a #19 drill.
2.3. Invert the Cessna 18X Upper Roll Bracket (P/N 1450-127) on the upper wing
skin and cleco the inner hole on the bracket to the hole drilled in the previous
step. Rotate the bracket so that the middle and outer bracket mounting holes are
aligned with the row of rivets in the rear wing spar as shown in Figure 3-3.

2.4. Match drill 2 holes as shown in Figure 3-3.
2.5. Remove the Cessna 18X Upper Roll Bracket (P/N 1450-127) from the wing and
deburr the mounting holes that were drilled.
2.6. Temporarily attach the Cessna 18X Upper Roll Bracket (P/N 1450-127) to the
Servo Bolt Pattern Plate (P/N 1420-216) using 2 ea. AN3-3A as shown in Figure
3-4.
Figure 3-4
2.7. Place the assembly shown in Figure 3-4 in the wing and cleco in place as shown
in Figure 3-5.

2.9. Drill Cessna 18X Lower Roll Bracket (1450-128) mounting holes.
2.9.1. Align the lower bracket mounting holes with row of rivets on
the lower spar flange.
2.9.2. Match drill the outboard mounting hole using a #19 bit from
inside the wing.
2.9.3. Secure the outboard hole with a cleco.
2.9.4. Match drill the remaining 2 holes on the Cessna 18X Lower Roll
Bracket (1450-128) installing a cleco after each hole is drilled.
2.9.5. Remove all components from the wing and debur the lower
mounting holes.
2.9.6. Remove the Servo Bolt Pattern Plate (P/N 1420-216) from the
Cessna 18X Upper Roll Bracket (P/N 1450-127).
2.10. Install anchor nuts in the Cessna 18X Upper Roll Bracket (P/N 1450-127) and
Drill Cessna 18X Lower Roll Bracket (1450-128). Rivet 3 ea. MS21051-08 anchor
nuts in place using 6 ea. MS20426AD3-4 rivets on each bracket.
2.11. Attach the appropriate roll servo arm to a 60 inch/lb PMA servo (P/N 8100-
064 for 12 volt or P/N 8100-065 for 24 volt) using the provided 8-32 x 3/8” flat
head screws. Use blue threadlocker (Loctite 242 or equivalent) and torque the
screws to 18-20 in-lb.

2.12. Allow a sufficient service loop and trim the roll servo wiring harness to length.
2.13. Terminate the roll servo wiring harness per the Vizion wiring diagram in the
Vizion PMA Installation Guide (TruTrak Doc. 166) and install the 9 Pin
Connector Backshell (2100-010).
2.14. Place the Cessna 18X Upper Roll Bracket (P/N 1450-127) and Cessna 18X
Lower Roll Bracket (1450-128) in the wing in approximately the final mounting
position but do not secure them to the wing.
2.15. Connect the roll servo wiring harness connector to the roll servo.
2.16. Place the roll servo assembly in the wing and loosely attach it to the Cessna
18X Upper Roll Bracket (P/N 1450-127) and Cessna 18X Lower Roll Bracket
(1450-128) using 4 ea. AN3-3A bolts with MS35333-39 lock washers and blue
threadlocker (Loctite242 or equivalent). The next steps must be performed
quickly so that the threadlocker does not begin to cure prior to final torqueing.
The roll servo arm should be oriented upward between the servo stops.
2.17. Align the Cessna 18X Upper Roll Bracket (P/N 1450-127) with the holes in the
upper spar and start 3 ea. AN526C-832R8 screws in the associated anchor nuts.
2.18. Align the Cessna 18X Lower Roll Bracket (1450-128) with the holes in the
upper spar and start 3 ea. AN526C-832R8 screws in the associated anchor nuts.
2.19. Fully tighten the upper and lower AN526C-832R8 mounting screws.
2.20. Torque the 4 AN3-3A servo mounting bolts to 20-25 in-lb.
2.21. Remove the inspecting cover near the left aileron bellcrank.
2.22. Loosen one of the aileron cable turnbuckles to allow for easy removal and
replacement of the bolt connecting the aileron cable to the bellcrank.

2.25. Verify that aileron rigging is correct according to the aircraft service manual
and adjust as needed.
2.26. Safety wire the aileron cable turnbuckle.
2.27. Fully thread an AN345-10 on a MM3-300 rod end bearing then partially thread
the MM3-300 rod end bearing in one end of the 41” push rod (2520-062).
2.28. Insert the push rod assembly in the aileron bellcrank inspection hole with the
rod end bearing going toward the roll servo.
2.29. Ensure that the aileron cable is not wrapped around the 41” push rod (2510-
062) then partially thread the MM3-300 rod end attached to the aileron
bellcrank in the outboard end of the push rod.
2.30. Have an assistant hold the yoke in the full right position and rotate the servo
arm against the outboard stop on the roll servo bracket.
2.31. Thread the MM-3-300 rod end bearing into the servo end of the pushrod until
the pushrod is the correct length to align with the drive point on the servo arm.
2.32. Verify that the control cable is not twisted around the pushrod.
2.33. Attach the pushrod assembly to the roll servo arm as shown in Figure 3-9 for
182E-182N or in Figure 3-10 for 182P-182T, R182 or TR182 and torque to 20-
25 in-lb.

2.34. Apply blue threadlocker (Loctite242 or equivalent) to the threaded shank of
both MM3-300 rod ends. Rotate the pushrod until the rod end bearings on each
end are threaded in equally then tighten the jam nuts to 20-25 in-lb.
2.35. Move the yoke throughout the full range of travel and check for binding in the
rod end bearings. If binding exists adjust the rod end bearings and jam nuts to
eliminate it.
2.36. Ensure that aircraft stops are contacted prior to servo stops. Adjust
length of pushrod as needed until servo stops are not contacted when
controls are moved to both ends of travel.
