4. Procedure
Subtask 73-13-43-420-062-A ** ON A/C NOT FOR ALL

A. Installation of the fuel distribution valve filter
(1) Install the filter:
(a) Lubricate a new AIPC 73-13-43-81-160 PACKING (9) with liquid paraffin (Material No.V10-066) and install it on the filter (8) (Ref. AMM TASK 70-23-13-911-010).
(b) Install the filter in the fuel distribution valve housing.
(2) Install the filter cover:
(a) Install a new packing.

CAUTION: FILTER COVER PACKING (1) IS MADE FROM A SPECIAL MATERIAL THAT PREVENTS OVER-HEATING. DO NOT USE AN ALTERNATIVE SEAL.

1 Lubricate a new AIPC 73-13-43-81-140 PACKING (1) with liquid paraffin (Material No.V10-066) and install it on the filter cover (7) (Ref. AMM TASK 70-23-13-911-010).
(b) Align the eight offset bolt holes.
(c) Lubricate the threads of the eight bolts (5) with lubricant (Material No.V10-067) .
(d) Install the bolts (5) and the eight washers (6) that attach the filter cover to the fuel distribution valve (10).
(e) TORQUE the bolts (5) to between 75 and 70 lbf.in (0.85 and 0.79 m.daN )

(Ref. AMM TASK 70-23-11-911-013).
(3) Install the fuel inlet line
(a) Lubricate a new AIPC 73-11-49-74-020 RING (2) with liquid paraffin (Material No.V10-066) and install it on the fuel inlet line (3) (Ref. AMM TASK 70-23-13-911-010).
(b) Install the fuel inlet line between the lower bifurcation panel and filter cover.
(c) Attach and torque the connection at the bifurcation panel.
(d) Install the three bolts (4) that attach the fuel inlet line to the filter cover.
(e) TORQUE the bolts (4) to between 95 and 85 lbf.in (1.07 and 0.96 m.daN )

(Ref. AMM TASK 70-23-11-911-013).
(f) Safety the bolts with corrosion resistant steel lockwire (Material No.V02-141) (Ref. AMM TASK 70-40-11-911-014).

5. Close-up
Subtask 73-13-43-410-056-A ** ON A/C NOT FOR ALL

A. Close Access
(1) Make sure that the work area is clean and clear of tools and other items.
(2) Close the thrust reverser halves (Ref. AMM TASK 78-32-00-410-010):
(a) FOR [1000EM1] (ENGINE-1)
451AL 452AR.
(b) FOR [1000EM2] (ENGINE-2)
461AL 462AR.

(2) Remove the access platform(s).
(3) Remove the WARNING NOTICE(S).

Subtask 73-13-43-790-055-A ** ON A/C NOT FOR ALL

D. Test Requirements
(1) Do an idle leak check (Ref. AMM TASK 71-00-00-710-012).

NOTE: A wet motor leak check (Ref. AMM TASK 71-00-00-710-046) may be used to check for leaks, but this must be followed by an idle leak check (Ref. AMM TASK 71-00-00-710-012).
