TORQUE SPECIFICATIONS
The A/C refrigerant system is a clutch cycling orifice tube type. The system components include
- A/C compressor (19703)
- A/C clutch assembly
- A/C condenser core (19712)
- A/C evaporator core (19860)
- A/C suction accumulator (19C836)
- connecting refrigerant lines
The refrigeration system operation is controlled by the
- A/C evaporator core orifice (19D990)
- evaporator air discharge temperature sensor (19C734)
- A/C compressor pressure relief valve (19D644)
- dual function pressure switch (19D594)
- low charge protection switch (19E561)
The refrigerant system incorporates an A/C compressor controlled by an evaporator air discharge temperature sensor.
The evaporator air discharge temperature sensor senses the A/C evaporator core temperature to control A/C compressor operation. For additional information concerning the evaporator air discharge temperature sensor, refer to CONTROL COMPONENTS .
An A/C pressure relief valve is installed in the A/C manifold and tube (19D734) to protect the refrigerant system against excessively high refrigerant pressures.
The A/C evaporator core orifice is installed in the condenser to evaporator tube (19835) to meter the liquid refrigerant into the A/C evaporator core.
