C. Installation of the Pivot Bolt Assembly
   (1) Make sure that the parts retained from the removed component are clean and in the correct condition.
   (2) Assemble the pivot bolt assembly (9) as follows:
     (a) Apply a thin layer of Synthetic Oil base Grease-General Purpose Clay Thickened - (Material No.03GBB1) or Synthetic Oil base Grease-General Purpose Lithium Thickened Low Temp. - (Material No.03GBC1) to the inner bolt (12).
     (b) Install the inner bolt (12) in the outer bolt (10).
     (c) Attach the inner bolt (12) to the outer bolt (10) with a new rivet (11) (NSA5414-40-000).
   (3) Apply a thin layer of Synthetic Oil base Grease-General Purpose Clay Thickened - (Material No.03GBB1) or Synthetic Oil base Grease-General Purpose Lithium Thickened Low Temp. - (Material No.03GBC1) to the splined bush (1) and to the pivot bolt assembly (9).
CAUTION: DO NOT REMOVE THE RETAINING WIRE RING FROM THE CARRIAGE BOLT ASSEMBLY. IF YOU DO, YOU MUST INSTALL A NEW CARRIAGE BOLT ASSEMBLY TO KEEP THE FAIL SAFE FUNCTION.
   (4) Install the 98D27504083000 EXTRACTOR - PIN TRACKS 2 AND 3 on the pivot bolt assembly (9).
   (5) Install the pivot bolt assembly (9) in the flap carriage with the 98D27504083000 EXTRACTOR - PIN TRACKS 2 AND 3. At the same time remove the 98D27504111000 SLAVE PIN-TRACK 2 & 3 from the flap carriage.

NOTE: Make sure that you install the extractor tool fully on to the threads of the pivot bolt assembly (9). This will let the carriage bushes compress the retaining ring (8) as the pivot bolt (9) is installed.
   (6) Remove the 98D27504083000 EXTRACTOR - PIN TRACKS 2 AND 3 from the pivot bolt assembly.
CAUTION: MAKE SURE THAT THE SPLINED BUSH IS FULLY ENGAGED WITH THE SPHERICAL BEARING. THIS PREVENTS DAMAGE TO THE PARTS.
