1. Remove the plug (4) and the On the manometer: packing (3) from the forward - the pressure reads between 6 mbar pressure measurement point 1025. (0.08 psi) and 10 mbar (0.14 psi).
-discard the packing (3).
-connect the MANOMETER (EMA84)
to the forward pressure
measurement point 1025 with a
piece of silicon tubing, I/D
4.0 mm (0.157 in.), approximate
length 2.0 m (6.5 ft.).
2. Disconnect the manometer and the
silicone tubing from the forward
pressure measurement point 1025.
-put the new packing (3) in
position on the plug (4) and
install the plug (4) in the
forward pressure measurement
point 1025.
-TORQUE the plug (4) to 70
lbf.in (0.79 m.daN) maximum.
3. Remove the screw (1) and the lock On the manometer: washer (2) from the aft pressure - the pressure reads between 11 mbar measurement point 1026. (0.15 psi) and 15 mbar (0.21 psi).
-discard the lock washer (2).
-connect the MANOMETER (EMA84)
to the aft pressure measurement
point 1026 with a piece of
silicone tubing, I/D 4.0 mm
(0.157 in.), approximate length
2.0 m (6.5 ft.).
