 MAIN GEAR TORSION LINKS - REMOVAL/INSTALLATION
______________________________________________
 1.  General_______
 A.  This procedure removes and installs the main gear torsion links.
 B.  The main gear torsion links are removed after damage, or when bushings are worn beyond service limits. Removal of the upper torsion link also disconnects the bottom end of the lower drag strut. On the right gear, the upper torsion link is connected to a spoiler lockout mechanism. The main tires should be removed and the shock strut partially extended to provide clearance for the upper torsion link pin when replacing the upper torsion link. The main gear brakes also should be removed to provide clearance for the lower torsion link pin when replacing the lower torsion link.
