A. Installation of the Engine-Pump Case-Drain Filter Differential-Pressure Indicator
F Engine-Pump Case-Drain Filter Differential-Pressure Indicator ** ON A/C NOT FOR ALL
   (1) Remove the blanking cover from the engine-pump case-drain filter differential-pressure indicator port.
   (2) Install the ring (20) and the packings (30):
CAUTION: RING (20) IS FITTED AT THE NEAREST POSITION TO THE HEXHEAD.
CAUTION: USE A NEW RING (20) AND PACKINGS (30) WHEN FITTING THE DIFFERENTIAL PRESSURE INDICATOR (10) IN THE FILTER MODULE PORT.
     (a) Put the AIPC 29-13-43-02-060 RING (20) on the engine-pump case-drain filter differential-pressure indicator (10).
     (b) Lubricate the AIPC 29-13-43-02-070 PACKING (30) and the AIPC 29-13-43-02-080 PACKING (30) with Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) .
     (c) Put the packings (30) on the engine-pump case-drain filter differential-pressure indicator (10).
     (d) Install the engine-pump case-drain filter differential-pressure indicator (10) in the filter head port.
     (e) TORQUE the engine-pump case-drain filter differential-pressure indicator (10) to between 14.7 and 12.5 m.N (130.09 and 110.62 lbf.in ) T.
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.
     (f) With the 14QMC1Wire-Locking Dia: 0.9 mm CRES -, safety the engine-pump case-drain filter differential-pressure indicator (10) to the filter head.
