R AGENTS (Material No. 11-026) to clean the thread of the cardan joint
R (5).
R (4) Apply SPECIAL MATERIALS (Material No. 05-047) to the thread of the
R cardan joint (5).
R (5) Install the washer (1) and the nut (2) and tighten the nut (2) by
R hand.
R (6) Loosen the strap (but not fully) on the HOIST (98D32104013004).
R (7) Move the side-stay (6) about the the side-stay center joint and
R install the cardan joint (7) in the MLG attachment lug.
R (8) Use a MISCELLANEOUS (Material No. 19-003) made moist with CLEANING
R AGENTS (Material No. 11-026) to clean the thread of the cardan joint
R (7).
R (9) Apply SPECIAL MATERIALS (Material No. 05-047) to the thread of the
R cardan joint (7).
R (10) Install the nut (8) and tighten by hand.
R (11) Disconnect the cables from the hook.
R (12) Disconnect the strap and remove the HOIST.
R (13) To tighten the nut (2):
R (a) Push the MLG as far as possible to the closed position. This will
R make sure that the cardan joint (5) is installed fully in the
R side-stay bracket.
R (b) Use the TORQUE ADAPTOR (460005812) to TORQUE the nut (2) to 25.0
R m.daN (184.36 lbf.ft).
R (c) Loosen the nut (2).
R (d) Do the steps (a), (b) and (c) two more times.
R (e) Use the TORQUE ADAPTOR to TORQUE the nut (2) to 18.0 m.daN
R (132.74 lbf.ft).
R (14) To tighten the nut (8):
R (a) Push the MLG as far as possible to the closed position. This will
R make sure that the cardan joint (7) is installed fully in the MLG

R (15) Use a feeler gage to measure the dimensions W and X as follows:
R (a) For in-service components:
R - the total clearance must be between 0.05 mm (0.0019 in.) and
R 0.5 mm (0.0196 in.).
R (b) For repaired or overhauled components:
R - the total clearance must be between 0.05 mm (0.0019 in.) and
R 0.2 mm (0.0078 in.).
R (16) Use a feeler gage to measure the dimensions Y and Z as follows:
R NOTE : The clearance can change around the pin and the bush____
R circumference. This is permitted if the maximum clearance is
