67-11  Cyclic Control Assembly (continued)

A. Removal (continued)

5. Remove  hardware  securing  C121-1  push-pull  tube  assembly  to  D320-8  stick 

assembly.    Remove  hardware  securing  C319-5  torque  tube  assembly  to  C177-5 

pivot assembly.  Move push-pull tube and torque tube assemblies aft, and protect 

from scratching.

6. Disconnect, but do not remove, two bolts securing cyclic friction assembly to cabin.  

Apply some cyclic friction to keep plates assembled.

7. Remove screws securing F338-1 cyclic box to cabin.  Lift and remove cyclic control 

assembly  with  attached  cyclic  box  and  friction  assembly.    Install  nuts  onto  two 

cyclic friction assembly bolts, hand tight, to retain bolts and spacers.

8. Remove hardware securing both outboard, vertical F121-5 push-pull tube assemblies 

and C130-47 spacer to D696-6 yoke assembly.  

9. Remove  hardware  securing  center,  vertical  F121-7  push-pull  tube  assemblies  to 

C958-6 bellcrank.  

10. Remove hardware securing G205-1 fork assembly to F334-1 support assembly.
11. Pull D175-5 cyclic pivot assembly (torque tube, yoke, bellcranks, fork, and push-pull 

tube assembly) aft through belly.

B.  Installation

1. Refer to Figure 67-1.  Verify center-to-center distance between rod end and spherical 

bearings in G205-5 fork is 5.40 ± 0.03 inches; adjust as required.  Standard torque 

jam nut and palnut per Section 20-32.  Install C175-5 cyclic pivot assembly (torque 

tube, yoke, bellcranks, fork, and push-pull tube assemblies) thru aft belly.

2. Connect  G205-1  fork  assembly to  F326-1  bellcrank  and  standard  torque  bolt  per 

Section 20-32.

3. Connect lower end of center F121-7 push-pull tube to C958-6 bellcranks and standard 

torque bolt per Section 20-32.

4. Connect lower ends of both outboard F121-6  push-pull tubes to D696-6 yoke using 

a NAS6605-46 bolt and C130-47 spacer and standard torque per Section 20-32.  

Install plastic hole plug in vertical keel panel beneath RH, aft seat.

5. Remove  temporary  nuts  from  cyclic  friction  assembly  bolts.    Position  cyclic  box 

with attached cyclic control and friction assemblies between keel panels.  Install all 

screws fastening cyclic box to cabin.  Fasten cyclic friction assembly to cabin and 

standard torque bolts per Section 20-32.

6. Connect C319-5 torque tube assembly to C177-5 pivot and standard torque bolts 

per Section 20-32.

7. Connect forward end of C121-1 push-pull tube to D320-8 cyclic stick and standard 

torque bolts per Section 20-32.
