No: 19-003) made moist with CLEANING AGENTS (Material No: 11-026) .

(2) Do an inspection of the component interface and/or the adjacent area.

(3) Do an inspection of the retaining nut (10) (Ref. NTM 572901). If the threads of the retaining nut (10)

are damaged or have corrosion, do one of the steps that follow:

(a) Record all areas of thread damage and corrosion on the data recording sheets specified in (Ref.

NTM 572901). Send the completed data recording sheets to Airbus Customer Support for the

necessary repair instructions.

or

(b) Do the repair by replacement of the forward pintle bearing retaining nut, (Ref. SRM 57261302).

(4) Make sure that the parts retained from the removed component are clean and in the correct condition.

(5) Put a thin layer of COMMON GREASES (Material No: 04-004) on the interface and the threads of the

bearing housing-halves (8).

(6) Fill the grease grooves in the bearing (7) and the bearing housing-halves (8) with COMMON GREASES

(Material No: 04-004) .

(7) Install the new (IPC-CSN 57-26-13-02) O-ring seal (9) in the seal groove of the bearing housing-halves

(8).

(8) Assemble the bearing housing-halves (8) and the bearing (7) together. Make sure that the identification

groove in the bearing (7) is adjacent to the flange of the bearing-housing assembly (6).

(9) Use the SOCKET-RING (FOR NUT OF FWD PINTLE BEARING) (98D57004003000) to install the

bearing-housing assembly (6) in the forward pintle fitting.

(10) TORQUE the bearing-housing assembly (6) to 5.6 M.DAN (41.30 LBF.FT).

(11) Make sure that the joint line of the bearing housing-halves (8) is not more than 20 degrees from the

aircraft horizontal (DIM ’X’).
