67-11 Cyclic Control Assembly (continued)
B. Installation (continued)
8. Connect all electrical plugs at bottom of cyclic stick. Ensure protective sleeving
covers maximum amount of wiring possible and sleeving ends are secured with
lacing tape.
9. Connect D918-1 cord to D320-8 cyclic stick. Connect D918-2 cord to C177-5
pivot.
10. Move cyclic control through all positions and verify operating and no binding.
11. Install radio face plate, connect OAT gage and hourmeter wiring connectors, and ty-
rap as required. Close and secure upper console.
12. Connect cyclic box cover anti-ice, pitot heat (if installed), and ELT (if installed) switch
wiring connectors and secure cover.
13. Install cyclic friction knob and secure with spring pin. Close and secure cyclic stick
boot.
14. Install F794-1 (forward) and F794-2 (aft) belly panels, F680-3 (pilot collective) and
F445-1 (forward tunnel) cover assemblies, and F461-1 (collective cross tube) and
F463-1 (aft tunnel) cover assemblies.
67-12 Cyclic Grip Assembly
A. Removal
NOTE
This may be accomplished without removal of complete cyclic
assembly from rotorcraft.
1. Remove forward belly panel.
2. Refer to Figure 67-1. Disconnect wiring connectors attached to wiring exiting base
of D320-8 cyclic stick. Using pin extractor, remove pins from housings (wires
112, 138, & 355 may remain installed) and retain housings. Remove lacing tape
from both ends of protective sleeving covering wires exiting base of stick assembly.
Attach a 3 foot length of safety wire or wire lacing tape to one removed pin.
3. As required, rotate grip assembly by pushing in on spring-loaded stop pin so exposed
wire loom does not wrap around top of D320-8 cyclic stick. Remove circular plug,
D684-1 spring, cotter pin, castellated nut, and washer where grip assembly attaches
to D320-8 cyclic stick.
4. Remove grommet atop cyclic stick at grip assembly wiring entrance. With a soft-
faced hammer, gently tap cyclic grip assembly pivot and remove grip assembly and
attached wiring from stick assembly. Ensure safety wire or lacing attached to internal
wiring protrudes from top and bottom of stick assembly. Also, ensure pivot bearings
remain with stick assembly.
NOTE
Do not damage bearings while removing.
