#3 – Main Gear Torque Links

WE ARE FINDING MOST OF THE AIRCRAFT HAVE ACCUMULATED ENOUGH HOURS AND LANDINGS TO WARRANT INSPECTIONS OF THE TORQUE LINK PIN HOLES. THE INSIDE BORES ARE CORRODED AND THE STRUT MATERIAL HAS WORN ENOUGH THAT THE PIN IS LOOSE. THIS CAN BE FOUND BY DEFLATING THE STRUT (400 HR. INSP. ITEM) AND SHIFTING THE LOWER STRUT SIDE TO SIDE. WATCH THE PIN AND SEE IF IT MOVES IN THE BORE. THIS CAN BE REPAIRED BY INSTALLING A STEEL SLEEVE IN THE HOLE BOTH IN THE UPPER BODY AND THE LOWER STRUT. IT REQUIRES THE REMOVAL OF THE LOWER STRUT AND MACHINING THE BORE AND THE UPPER BODY CAN BE REWORKED ON THE WING USING A TOOL DEVELOPED BY US. BOTH SLEEVES MUST BE INSTALLED WITH THE AID OF LIQUID NITROGEN. THIS WILL ELIMINATE ANY FURTHER DAMAGE FROM CORROSION AND ALLOWS ANY FURTHER SHIMMING FOR CLEARANCES TO LAST LONGER WITHOUT POUNDING OUT THE SHIM STOCK.
