4. Procedure
Subtask 26-23-14-920-052-C ** ON A/C NOT FOR ALL

WARNING: USE PROTECTIVE GOGGLES AND GLOVES WHEN YOU REMOVE OR INSTALL LOCKWIRE. EACH TIME YOU CUT LOCKWIRE, REMOVE AND DISCARD IT IMMEDIATELY. LOOSE LOCKWIRE CAN CUT YOU OR MAKE YOU BLIND, AND/OR CAN CAUSE DAMAGE.

CAUTION: MAKE SURE THAT THE WATER-ABSORBING FILTER ELEMENT IS NOT OUT OF A SEALED CONTAINER FOR MORE THAN 30 SECONDS. THE ELEMENT WILL ABSORB WATER FROM THE AIR AND BECOME UNSERVICEABLE.

A. Replacement of the Water-Adsorbing Filter

NOTE: The replacement procedure is the same for both water-adsorbing filters. Thus, the procedure to replace only one water-adsorbing filter is given here.

(1) Remove and discard the lockwire from the filter bowl (1).
(2) Remove the filter bowl (1) from the filter head (4).
(3) Remove and discard the o-ring (3) and the water-adsorbing filter (2).
(4) Make sure that the filter bowl (1) and the filter head (4) are clean and in the correct condition.
(5) Apply hydraulic fluid:

CAUTION: APPLY A SMALL QUANTITY OF THE CORRECT HYDRAULIC FLUID ON THE O-RING. THIS WILL PREVENT DAMAGE TO IT. MAKE SURE THAT HYDRAULIC FLUID DOES NOT GO INTO THE FILTER. HYDRAULIC FLUID IN THE FILTER CAN CAUSE A MALFUNCTION OF THE SYSTEM.

(a) Apply a small quantity of Mineral Hydraulic Fluid-Damper - - (Material No.02BBB9) to the new AIPC 26-23-14-01-050 O-RINGS (3).
(6) Install the new o-ring (3) on the filter head (4).
(7) Install the new AIPC 26-23-14-01-030 WATER-ADSORBING FILTER (2) together with the filter bowl (1) on the filter head (4).

(8) Safety the filter bowl (1) with lockwire 14QFB1Wire-Locking Dia: 0.8 mm CRES Nickel Alloy -.
