   (1) Drain the fuel from Fuel Cooled Oil Cooler (FCOC).
     (a) Cut and discard the wire which safeties the fuel drain plug (6) to the fuel plug.
NOTE: Do not cut the wire which safeties the fuel plug to the cap assembly (8).
     (b) Put the CONTAINER 10 L(2 1/2 USGAL) minimum capacity in position to catch the drained fuel.
     (c) Remove the fuel drain plug (6) from the fuel plug and drain the fuel in the clean container.
     (d) Remove and discard the sealing ring (5).

Subtask 73-12-42-020-058-A ** ON A/C NOT FOR ALL
CAUTION: DO NOT TAMPER WITH ANY OF THE SCREWS (QTY:6) THAT RETAIN THE FCOC ADAPTER AS THIS CAN CAUSE ADAPTER MISALIGNMENT AND FUEL LEAKAGE.
B. Removal of the Fuel Filter Element.

POST SBE 79-0086

   (1) Remove the cap assembly (8) from the FCOC.
     (a) Remove the twelve nuts (1) and the washers (2) which attach the cap assembly (8) to the flange of the FCOC. Take care to remove the nuts gradually and smoothly in a symmetrical sequence so a single nut is never subjected to the total spring force on the cap. This also ensures that the components move apart gradually and do not become damaged.
     (b) Remove the cap assembly and discard the sealing ring (4).
   (2) Remove the fuel filter element (3) from the FCOC.
     (a) Do a visual inspection of the fuel filter element for signs of contamination (Ref. AMM TASK 73-12-42-200-010).
     (b) Discard the fuel filter element (3).

POST SBE 79-0086

   (1) Examine the cap assembly (8) mating face.
     (a) If damaged, reject the FCOC.
   (2) Examine the sealing ring location on the cap assembly (8).
     (a) If damaged, reject the FCOC.
   (3) Examine the FCOC mating face.
     (a) If damaged, reject the FCOC.
