CAUTION: WHEN FEEDING CABLE INTO CONDUIT, HOLD CABLE NO FARTHER BACK THAN THREE TO FOUR INCHES FROM CONDUIT OPENING TO PREVENT KINKING.
(4)
With threaded connector end of conduit forward, push conduit and cable assembly through the fairleads on engine firewall, starting at aft fairlead, till conduit bracket bulkhead connection is reached.
(5)
Attach forward end of cable.
(a)
On TELEFLEX assembly, connect forward telescopic unit swivel assembly threaded connector at bulkhead connection. Tighten nuts and lockwire.
(b)
On CONTROLEX assembly, install five washers on cable union, insert through support bracket, and install one washer and nut on forward side of bracket. Tighten nut and lockwire union nut to union.
(6)
Secure conduit to bracket on engine firewall with clamp. Before clamping check that there are no sharp bends in the conduit run.
(7)
Proceed to step D.
B. Prior to inserting forward TELEFLEX cable into an installed conduit, check cable for lubrication. If cable is not thoroughly greased apply Dow Corning 33 light grade lubricant.
CAUTION: HANDLE CABLE WITH CARE TO AVOID CONTAMINATION AND PREVENT KINKING. A KINKED CABLE IS CAUSE FOR REJECTION. GROOVED CABLE END MUST SHOW NO SHARPNESS WHEN MOVED BETWEEN FINGERS. DEBURR AND BUFF IF NECESSARY.

C. With conduits uncoupled at quick disconnect, insert rounded end of cable into aft end of conduit at quick-disconnect coupling and thread through conduit until end of cable comes out through end of forward swivel assembly. If any obstructions are felt, move cable back and forth to assure unforced passage. (Helixes on cable have a tendency to catch any discontinuities in the conduit due to stiffness of this cable.)
CAUTION: WHEN FEEDING CABLE INTO CONDUIT, HOLD CABLE NO FARTHER BACK THAN THREE TO FOUR INCHES FROM OPENING IN END OF TELESCOPIC UNIT SLEEVE.
D. Install aft cable and conduit assembly.
NOTE: Aft cable and conduit should be installed as a unit.
(1)
Install TELEFLEX aft cable and conduit.
(a)
Check TELEFLEX cable for lubrication. If cable is not thoroughly greased apply Dow Corning 33 light grade lubricant.
CAUTION: HANDLE CABLE WITH CARE TO AVOID CONTAMINATION AND PREVENT KINKING. A KINKED CABLE IS CAUSE FOR REJECTION. GROOVED CABLE END MUST SHOW NO SHARPNESS WHEN MOVED BETWEEN FINGERS. DEBURR AND BUFF IF NECESSARY.
(b)
Position aft rigid section of push-pull cable on tailpipe extension. Aft part of cable must be inserted through shroud bulkhead.
CAUTION: WHEN INSERTING CABLE THROUGH SHROUD BULKHEAD HANDLE CABLE WITH CARE TO AVOID CONTAMINATION AND PREVENT KINKING. A KINKED CABLE IS CAUSE FOR REJECTION.
(c)
Tighten union in aft rigid section of push-pull cable.
(d)
Secure push-pull cable to brackets on tailpipe extension with screws.
(e)
Secure push-pull cable to shroud bulkhead with bolts and lockwire. (Fig. 401, sheet 2, detail D)
(f)
Attach push-pull cable to feedback control lever with bolt, nut, washer, and bushing.
(g)
Secure rigid section of push-pull cable to engine shroud with bolts.
(2)
Install CONTROLEX aft cable and conduit.
(a)
The CONTROLEX cable assembly includes a flat steel center core which will bend easily in the flat plane, but resists bending in the edgewise direction and may be damaged if forced. Make all bends while holding the unsupported end of the cable assembly straight. Do not force the cable into any position.
(b)
Install the disconnect end forward through the engine shroud and bolt in place.
(c)
Attach clamps to tailpipe extension (2 places) and leave loose.
(d)
Insert aft end through shroud bulkhead. The cable union should have four washers on the forward side and two washers on the aft side of the mounting plate and should be tight. Install bolts in mounting plate.
(e)
Attach bracket marked OUT to tailpipe extension with marking visible. Leave bolts loose.
