Procedure to Remove the Main Landing Gear Truck Positioner Actuator

 S 034-024
 (1)  
POSITIONER ACTUATOR WITH CLAMP; remove the clamp that holds the hydraulic lines from the positioner actuator.

 S 034-004

 (2)  
Disconnect the hydraulic lines from the actuator. Install plugs in the lines and fittings.

 S 014-030

 (3)  
Do these steps to permit removal of the pin from the rod end of the actuator (Fig. 402):

 (a)  
Remove the bolts which hold the cover to the J-1 junction box

 NOTE: The junction box is on the aft end of the truck beam of
____
 the main gear.

 (b)  
Put a tag with the color code and the pin locations on the sensor wires

 (c)  
Use a pin extraction tool, to remove the sensor wire from the terminal block in the junction box

 (d)  
Put a line on the sensor wires to make the installation easier

 (e)  
Disconnect the conduit coupling nut from the junction box

 (f)  
Remove or loosen the clamp that attaches the conduit to the truck beam

 (g)  
Move the conduit to permit removal of the pin.

 S 034-005
 (4)  Remove pin (1) to disconnect the rod end of the actuator from the truck beam (View A-A).
