5-5b. INSTALLATION OF CONTROL COLUMN ASSEMBLY (PA-32R-300). (Refer to Figure 5-1a.)
a. The tee bar assembly may be installed in the airplane by the following procedure:
1. Swing the tee bar assembly into place from the right side of the cabin and secure with
attachment bolts (3), washers and nuts inserted in through each side of the floor tunnel.
2. Connect the stabilator control cables (23) to the lower end of the tee bar with bolt (3), washer,
nut and cotter pin. Allow the cable ends free to rotate.
3. Place the aileron control cables (22) around the pulleys (21) that attach to the lower section of
the tee bar (7); position pulleys and secure with bolt, washers and nut.
4. Install the control wheel per Step b.
5. Place the control wheels in neutral (centered) position and install the aileron control chains (14
and 16) on the control wheel sprockets (1 and 13) and idler cross-over sprockets (15 and 18).
The turnbuckle (6) must be centered between the two control wheel sprockets.
6. Loosen the connecting bolts (3) of the idler sprockets (15 and 18) to allow the chain to fit snug
around the control wheel sprockets and over the idler sprockets.
7. Connect the aileron control cables (22) to the ends of the chains (14 and 16) with bolts,
bushings, nuts and cotter pins (19).
8. Adjust the chain turnbuckle (6) between the two control wheel sprockets to allow the control
wheels to be neutral and obtain proper cable tension as given in Table V-II. It may be necessary
in order to have both control wheels neutral to set the chain turnbuckle to neutralize the wheels
and then set cable tension with the turnbuckles located under the floor panel aft of the main
spar as instructed in Paragraph 5-11. Before safetying the turnbuckle, check that when the
ailerons are neutral, the control wheels will be neutral and the chain turnbuckle centered. Also
the aileron bellcranks should contact their stops before the control wheel hits its stop. Maintain
.030 to .040 clearance between sprocket pin and adjustable stop bolts on models having
adjustable tee bar stops.
9. Set stabilator cable tension with the turnbuckle in the aft section of the fuselage and instruction
given in paragraph 5-15. Check safety of all turnbuckles upon completion of adjustments.
10. Tighten (torque 45 + or - 5 in. lbs.) the connecting bolts (3) of the idler sprockets ( 15 and 18).
11. Install the floor tunnel plate and secure with screws. Fasten the tunnel carpet in place.
b. Either control wheel assembly may be installed by the following procedure:
1. Insert the control wheel tube through the instrument panel.
2. Should wires for the various Autopilot systems need to be installed in the control tube, route
them through the hole in the forward side of the tube and out of the small hole in the side.
Position the rubber grommet in the hole in the side of the tube.
3. On the left control tube, install the stop (12).
4. Connect the control wheel tube (4) to the flexible joint (2) of the tee bar assembly. If the
control cables and/or chains have not been removed or loosened, place the ailerons in neutral
and install the control tube on the flexible joint to allow the control wheel to be neutral. Install
bolt, washer and nut (3). Then tighten.
