R (a) Make sure that there is no friction point when each torque link
R arm moves.
R (b) Clean the threads of the shaft (1) and the nut (6) with CLEANING
R AGENTS (Material No. 11-004A) and dry them with filtered
R compressed air.
R (c) Apply a light coat of COMMON GREASE (Material No. 04-022) to the
R washers (2), (3) and (4) and to the shaft (1).
R (d) Align the center bores of the upper and lower arms of the torque
R links and install the washers (2), (3) and (4).
R (e) Install the shaft (1).
R (f) Make sure that the play at the torque link hinges is correct
R (Ref. TASK 32-21-00-200-003).
R (g) Do the torque procedure on the nut (6)
R 1_ Apply a layer of SPECIAL MATERIALS (Material No. 05-047) to

R 2_ Apply a layer of SPECIAL MATERIALS (Material No. 05-047) to
R the threads of the nut (6) and install it.
R 3_ TORQUE the nut (6) to 9 m.daN (66.37 lbf.ft) and loosen the
R nut (6). Do this three times.
R 4_ Loosen the nut (6) to get a clearance between 0.02 mm (0.0007
R in.) and 0.1 mm (0.0039 in.).
R 5_ Make sure that you can align a hole of the nut (6) with the
R slot of the shaft (1) and keep the clearance given above.
R If not:
R - loosen the nut (6),
R - remove the washer (5),
R - adjust the thickness of the washer (5) to get the clearance
R given above with a hole of the nut (6) aligned with the slot
R of the shaft (1),
R NOTE : The total thickness of the washer (5) (shoulder____
R included) must not be less than 4 mm (0.1574 in.). If
R the thickness of the washer (5) is less than 4 mm
R (0.1574 in.), replace it with the new washer (5).
R - do a passivating treatment on the reworked surface (Ref. CMM
R 320901),
R - do the torque procedure on the nut (6) again.
R 6_ Apply a layer of SPECIAL MATERIALS (Material No. 05-047) to
R the threads of the screw (10).
R 7_ Install the screw (10), the washer (7), the nut (8) and
R tighten it.
R 8_ Install the new cotter pin (9) on the nut (8).
R (5) Apply a layer of SEALANTS (Material No. 09-001) to the areas
R identified E.
R (6) Make sure that the lubrication points are clean and in good condition
R on the shaft (1).
