4. Procedure

NOTE: The slat actuators are vented units filled with grease. It is normal for this grease to have some oil separation. The external surfaces of the slat actuators may be moist with this separated oil as they are not hermetically sealed units. But, any separated oil in the units that touches the grease will be changed back during operation. The oil separation will decrease during in-service operation until the lubricant is in a condition that is stable. This is normal and will not cause damage to the units.

Subtask 27-84-49-420-053-A

A. Preparation for Installation
(1) Clean the component interface and/or the adjacent area with Textile-Lint free Cotton - (Material No.14SBA1) made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) .
(2) Do an inspection of the component interfaces and the adjacent area.
(3) Make sure that the parts retained from the removed component are clean and in the correct condition.
(4) Apply a thin layer of Mineral Oil base Grease-Anti-Fretting Paste - (Material No.03FDB1) to the actuator output splines.
(5) If the 98D27804007000 TOOL-ALIGNMENT AND LOCKING (SLAT TRACKS 5 TO 12) are installed, remove one 98D27804007000 TOOL-ALIGNMENT AND LOCKING (SLAT TRACKS 5 TO 12) and install the applicable actuator before you remove the other 98D27804007000 TOOL-ALIGNMENT AND LOCKING (SLAT TRACKS 5 TO 12).
