A. Installation of the Compressor Overheat-Temperature Sensor
(1)
Make sure that the parts retained from the removed component are clean and in the correct condition.
(2)
Make sure that the removed packing (3) is in a good condition. If necessary replace the packing (3).
(3)
Remove the blanking plugs from the disconnected line ends.
(4)
Clean the component interface and/or the adjacent area.
(5)
Apply a small quantity of COMMON GREASE (Material No. 04-012) to the contact faces of the compressor overheat- temperature sensor (1) and to the packing (3).
(6)
Put the packing (3) in position on the compressor
overheat-temperature sensor (1).
(7)
Install the compressor overheat-temperature sensor (1) in the pipe assembly (4).
(8)
TORQUE the compressor overheat-temperature sensor (1) to between 0.5 and 1.0 m.daN (44.24 and 88.49 lbf.in).
(9)
Wipe clean the excess COMMON GREASE (Material No. 04-012) from the compressor overheat-temperature sensor (1) and safety with MISCELLANEOUS (Material No. 19-009).
(10)
Remove the blanking caps and connect the electrical connector (2).
(11)
Make sure that the work area is clean and clear of tool(s) and other items.
