Subtask 29-32-12-420-054
A. Installation of the Pressure Switch
(1)
Clean the component interface and/or the adjacent area.
(2)
Do an inspection of the component interface and/or the adjacent area.
(3)
Remove the blanking plugs from the ports of the manifold.
(4)
Lubricate the new O-ring (3) with HYDRAULIC FLUIDS (Material No. 02-003).
(5)
Put the new O-ring (3) in position on the system pressure switch (2).
(6)
Install the system pressure switch (2) in the manifold (4) and TORQUE to between 3.186 and 3.470 m.daN (23.49 and 25.58 lbf.ft).

HYDRAULIC FLUID TEMPERATURE INDICATING - DESCRIPTION AND OPERATION
__________________________________________________________________
1. General_______
The temperature indicating system monitors the temperature of the hydraulic fluid in the three hydraulic systems. If the fluid temperature is too high, the indicating system data is used to generate warnings in the flight compartment.
