E. Install spring pin (14) in each trunnion pin lockpin.
F. Lockwire each spring pin.
G. Apply grease to threads of each trunnion pin (20) and to faces of lockwashers (11). Install lockwashers and jamnuts.
H. Tighten jamnuts (12) on each trunnion pin 500 to 600 pound-inches lube torque. After tightening jamnuts (12), check that there is no gap between spherical bearing and trunnion bearing flange (view 1).
I. Lockwire lockwashers (11) and jamnuts (12) together.
J. Connect nose gear piston position cables (NGPPA, NGPPB).
(1)
Feed piston position cables through left trunnion pin, pressure seal retainer ring (25), inboard left trunnion pin nut (19), and through respective cable pulley brackets to piston position cable quadrant on aft side of shock strut.
(2)
Install cable guards or pulleys, which were removed when cables were disconnected.
(3)
Insert cable terminals in respective recesses in quadrant and install terminal retaining cotter pins in holes at end of recesses.
(4)
Connect piston position cables to respective turnbuckles and adjust cable tension. (Ref 32-51-0 A/T)
(5)
Install locking clips in turnbuckles.
K. Connect nose wheel steering cables.
(1) Feed steering cables (NWSA, NWSB) through left trunnion pin, pressure seal retainer ring (25), inboard left trunnion pin nut (19), and through respective cable pulley brackets to steering collar (33).

(2)
Install cable guards or pulleys, which were removed when cables were disconnected. Adjust cable guard to clear pulley by 0.015 to 0.045 inch.
(3)
Insert steering cable terminals (NWSA, NWSB) in their respective recesses in grooves on aft side of steering collar (33).
(4)
Install spring pins (32) in holes provided in steering collar.
(5)
Lockwire spring pins with NC20 lockwire (30).
(6)
Connect steering cables to their respective turnbuckles and adjust cable tensions, refer to 32-51-0.
(7)
Install locking clips in turnbuckles.
L. Assemble pressure seal (24) segments around nose gear piston position cables (NGPPA, NGPPB) and nose wheel steering cables (NWSA, NWSB) at inboard end of left trunnion pin (20).
M. Position each half of pressure seal retainer (27, 28) and install eyebolt (26) with nut (29). Tighten nut sufficiently only to clamp the seal segments then loosen approximately 1/4 turn until eyebolt can be rotated with fingers.
N. Slide assembled pressure seal on cables in end of trunnion pin. Insert and push assembled seal, with ring (25), into trunnion pin (20) until seal hits a stop.
O. Install nut (19) in inboard end of left trunnion pin.
P. Tighten nut 100 to 150 pound-inches lube torque then back off as required to suit vernier of lock holes.
Q. Install nut lock (21) on left inboard trunnion pin nut and install cap screw (22) to retain nut.
R. Lockwire cap screw by double-twist method with NC32 lockwire.
S. Check that seal assembly rotates freely from gear extended cable position to a simulated gear retracted cable position to ensure cables will not become twisted when gear is retracted.
T. Connect nose gear drag brace lower link (8) at fitting (5) on shock strut.
(1)
Lubricate outside of drag brace lower bolt (9) with grease.
(2)
Install nylon washer (7) on bearing in drag brace lower link (8) and slide link into fitting (5) on shock strut.
