 MAIN GEAR SHOCK STRUT SEALS - MAINTENANCE PRACTICES
___________________________________________________
 1.  General_______
 A.  This procedure contains four tasks. The first task does a check of the strut for serviceability. The other tasks replace the seals on the shock strut of the main landing gear. Task two replaces the seals with the spare seals. Two sets of spare seals are in the gland nut of the shock strut. Task three replaces the active seals and the spare seals. Task three is used when the two sets of spare seals have been used. Task four is an optional procedure that replaces the active seals and the spare seals from the top of the inner cylinder.
