V.  Connect reaction link to shock strut.
(1)  
Place reaction link universal (3, Fig. 406) in position on trunnion pin (6) inboard eye with bolt locking flat aft.

(2)  
Install thread protector on spring support shaft (5). Insert shaft from aft side.

(3)  
Remove thread protector, install washer (2A) and spring support cap (2).

(4)  
Tighten cap hand-tight; if necessary, back off cap to align nearest castellation with cotter pin hole in shaft. Lock cap with cotter pin.

(5)  
Connect downlock springs (1, Fig. 406) to spring support shaft (5) and cap (2).

NOTE:  Connect cord to end of downlock spring and pass cord over trunnion link or shock strut. Spring can be extended to align with attachment points by pulling on cord or use spring expander assembly to extend spring.
W.  Deleted
X.  Remove hydraulic floor jack.
Y.  Install hydraulic swivel (11, Fig. 403) and door actuation fitting (13) on trunnion link (10). Remove plugs and caps and connect upper hydraulic lines.
Z.  Install clamps (8, Fig. 403) and hydraulic lines (7) on gear. Remove plugs and caps. Connect all
lines. AA. Install the actuator assembly of the main landing gear as follows:
(1)  
If you remove the actuator assembly in the step before, install the actuator assembly (AMM 32-32-11/401).

NOTE:  If the stabilizing beam for the main landing gear was installed after the removal of the actuator assembly, it may be removed to make the installation of the actuator assembly easier.

(2)  
If the actuator assembly was disconnected from the walking beam arm and the trunnion pin in the step before, do the steps that follow:

(a)  
Position the actuator assembly for installation.

(b)  
Remove the cord that attached to the actuator assembly.

(c)  
Connect the actuator assembly to the walking beam arm and the trunnion pin (AMM

32-32-11/401). AB. Install electrical harness (9).
CAUTION:  CHECK WIRING HARNESS IN AREA PASSING UNDER AXLE FOR DAMAGE OR PREVIOUS REPAIR. IF WIRES HAVE BEEN DAMAGED OR SPLICED, REPLACE HARNESS.
AC. Install shock strut doors (AMM 32-13-11/401).

AD. Jack airplane for gear retraction (Ref Chapter 7, Jacking Airplane).
AE. Adjust doors (Ref 32-13-11, Removal/Installation).
AF.  Service shock strut and lubricate gear (Ref Chapter 12, Main Landing Gear Shock Strut Servicing and Main Landing Gear Lubrication, respectively).
AG.  If right gear is being installed, connect ground spoiler interlock valve cable (Ref 27-62-51 R/I).
AH. Pressurize hydraulic systems A and B and bleed brakes by operating brake pedals four to six times (Ref 29-11-0 and 29-12-0, Maintenance Practices).
(1) Check hydraulic brake line connections for leaks and lines are not cross connected.
(a)  
Ensure that hydraulic ground interconnect valve is in CLOSED position.

(b)  
Pressurize B hydraulic system.

(c)  
Depress brake pedals and verify that only outboard brakes are actuated.

NOTE:  Actuation of one of the inboard brakes is an indication that hydraulic tubes are cross connected.
AI.  Check operation of skid detectors of newly installed main landing gear.
(1)  
Provide electrical power to antiskid system.

(2)  
Close all landing gear circuit breakers on P6 panel.

(3)  
Check that wheel chocks are in place.

(4)  
Release parking brake.

(5)  
Set inboard and outboard antiskid switches on pilot's panel to OFF position. Check that ANTISKID INOP lights are on.

(6)  
Set both inboard and outboard antiskid switches to ON position. Check that ANTISKID INOP lights go off.

(7)  
Set parking brake. Check that ANTISKID INOP lights go off.

NOTE:  The ANTISKID INOP lights may come on momentarily when parking brake valve opens or closes.

(8)  
Release parking brake. Check that ANTISKID INOP lights remain off.

(9)  
Pull inboard antiskid circuit breaker. Check that inboard ANTISKID INOP light comes on.

(10)
Push inboard antiskid circuit breaker in. Check that inboard ANTISKID INOP light goes off.
