CAUTION: USE A SECOND WRENCH TO APPLY COUNTERTORQUE TO THE UNION WHEN YOU DISCONNECT/CONNECT HYDRAULIC LINES ON UNIONS. IF YOU DO NOT USE THE SECOND WRENCH, THERE IS A RISK THAT YOU WILL LOOSEN OR TIGHTEN THE UNION TOO MUCH.
CAUTION: YOU MUST INSTALL HYDRAULIC TUBES WITH HYDRAULIC FLUID AS LUBRICANT.
B. Installation of the Electric Pump
NOTE: It is necessary for a second person to hold the pump (6) while you connect the electrical connector (9), and attach the pump (6) (to the structure of the aircraft).
NOTE: The pump (6) weighs approximately 15 Kg (33 lb.).
   (1) Clean the component interfaces and the adjacent area.
   (2) Do an inspection of the component interfaces and the adjacent area.
   (3) Hold the pump (6) in position on the structure, and install the four bolts (18).
   (4) If removed, install the washers (20). Connect the bonding lead (17) at the same time.
   (5) Install the new AIPC 29-12-03-09-020 NUTS (14) or AIPC 29-12-83-09-150 NUTS (14) and tighten.
NOTE: If new nuts (14) are not available, use the removed nuts, but do not use the nuts (14) more than three times.
   (6) If the new nuts (14) are not available, do a breakaway torque check of each nut. The minimum breakaway TORQUE value must be 0.04 m.daN (3.54 lbf.in). If the breakaway torque value is less than the limit, replace the nut(s).
   (7) Remove the blanking plugs from the hydraulic line end-fittings, and the blanking caps from the unions of the pump (6).
   (8) If the unions (3), (12) and (15) were removed, do the steps that follow:
     (a) Apply the Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) to the new AIPC 29-12-03-09-080 PACKING (29) or AIPC 29-12-83-09-240 PACKING (29) and the AIPC 29-12-03-09-070 UNION (3) or AIPC 29-12-83-09-230 UNION (3).
