B. Removal of the Case-Drain Filter

AFTER SB RA32029-5
   (1) Remove the blanking covers from the ports of the filter module (5), the union (10) and the elbow (35).
   (2) Lubricate the packings (7) with Phosphate Ester Hydraulic Fluid-General Power - - (Material No.
02ABA1) and put on the union (10). Install the union (10) in the port at the top of the filter module.
   (3) TORQUE the union (10) to between 300 and 250 lbf.in (3.39 and 2.83 m.daN ) T.
   (4) Lubricate the packings
AIPC 29-11-43-01-020 PACKING (25) with Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) . Install the packing (25), the nut (30) and the elbow (35) into the port of the filter module.
   (5) TORQUE the nut (30) and elbow (35) on the filter module to between 200 and 180 lbf.in (2.26 and 2.03 m.daN ) T.
   (6) Attach the filter module (5) to the filter support bracket with the four bolts (15) and the washers (20).
   (7) TORQUE the bolts (15) to between 70 and 50 lbf.in (0.79 and 0.57 m.daN )
T.
   (8) Safety the two left filter-module mount bolts (15) with 14QFB1Wire-Locking Dia: 0.8 mm CRES Nickel Alloy -.
   (9) Safety the filter element case with lockwire to the two right filter module mount bolts (15).
   (10) Remove the blanking covers from the case drain upper and lower hose couplings
   (11) Connect the case drain upper hose to the union (10) on the filter module.
   (12) TORQUE the upper hose coupling nuts to between 245 and 215 lbf.in (2.77 and 2.43 m.daN )
T.
   (13) Connect the case drain lower hose to the elbow (35) on the filter module.
   (14) TORQUE the lower hose coupling nuts to between 245 and 215 lbf.in (2.77 and 2.43 m.daN )
T.
NOTE: Use a second WRENCH - TORQUE to hold the fittings when you torque the coupling nuts. This prevents damage to the hose.
Subtask 29-11-43-710-053-A ** ON A/C NOT FOR ALL
C. Operational Test
   (1) Do an operational test of the Green hydraulic system (
Ref. AMM TASK 29-11-00-710-001).
   (2) During the dry motoring of the Engine 1, make sure that:
  • there are no leaks from the case drain filter,
  • the clogging indicator of the filter is not extended.
