801244 Auto Air Con Clutch Replacement For Toyota VIOS

  The car air conditioning compressor is the heart of the car air conditioning refrigeration system. It plays a role in compressing and transporting refrigerant vapor.
There are two types of compressors: fixed displacement and variable displacement. According to different working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors. The introduction of fixed displacement compressors for automobiles is as follows: 1. The displacement of fixed displacement compressors increases proportionally with the increase of engine speed, and cannot automatically change the power output according to the refrigeration demand, which has a significant impact on engine fuel consumption; 2. It is generally controlled by collecting temperature signals from the evaporator outlet. When the temperature reaches the set temperature, the electromagnetic clutch of the compressor is released, and the compressor stops working; When the temperature rises, the electromagnetic clutch engages and the compressor starts working. The constant displacement compressor is also controlled by the pressure of the air conditioning system. When the pressure in the pipeline is too high, the compressor stops working.

1. First confirm whether the compressor malfunction has been resolved, and

2. Whether the compressor is not working due to damage to the electromagnetic clutch.

3. Is there any jamming or burning of the old compressor.

4. Conduct a comprehensive inspection of the compressor.

5.If it is confirmed that the fault occurred on the electromagnetic clutch and the compressor pump body is not damaged, then the electromagnetic clutch can be replaced.

6.Before replacing the electromagnetic clutch, please use a multimeter to test the machine and see if it is engaged.

7. Confirm that the electromagnetic clutch is the same as the old compressor electromagnetic clutch.

 The electromagnetic clutch of the car air conditioning is controlled by the air conditioning switch, temperature controller, air conditioning amplifier, pressure switch, etc. It can connect or disconnect power transmission between the engine and compressor. Yes, so it is universal.
The solution is as follows: 1. Abnormal engagement, slipping or damage of the electromagnetic clutch can cause abnormal noise. Check the clutch solenoid valve coil and readjust the clutch clearance according to regulations. 2. The car air conditioning compressor has abnormal noise. Is there oil, is the belt worn, and is the air conditioning compressed.
Only the car's air conditioning compressor has a clutch to control the start and stop of the compressor.
The reason for the slipping of the electromagnetic clutch of the car air conditioning compressor is that the operating torque of the compressor is greater than the torque that the clutch can provide. 2. The compressor valve plate is broken, the bearings are damaged, or the seals are damaged. Mechanical fluid, which is the heart of a refrigeration system, draws from it.
The main reasons for the slipping of the electromagnetic clutch of the car air conditioning compressor are as follows: 1. If the electromagnetic clutch of the compressor slips, you can start the engine and turn on the air conditioning for inspection. The working surface of the pulley is not severely worn, located on the right side.
A certain gap is required. The size of the gap is not closely related to the impact force, but the suction force will be large, and the gap will increase the magnetic gap, affecting the suction force.
