DKS32C 2B Bus Air Conditioner Compressor For Nissan Bus TM31 WXBS011

Parameter:

AC compressor replacement process.

1. Drain the refrigerant: Before starting the disassembly, the technician needs to use special equipment to drain the refrigerant from the entire air conditioning system to ensure work safety. This is very important because refrigerants are toxic and harmful to the environment when released into the atmosphere.

2. Remove the drive belt: The technician will remove the drive belt from the AC compressor clutch pulley and separate the clutch from the wires. This makes it easier to remove and replace the compressor.

3. Disconnect the refrigeration lines: The technician will need to disconnect the low-pressure and high-pressure refrigeration lines that are connected to the compressor body. These lines are usually connected by quick connectors that technicians can remove using special tools.

4. Replace the compressor: The technician will unbolt the damaged compressor and remove it. They will then install a new AC compressor and re-tighten it.

5. Reconnect lines and drive belts: Once the new compressor is installed, technicians will reconnect the low-pressure and high-pressure refrigeration lines. They will then reattach the drive belt and wires, making sure everything is connected correctly.

6. Refrigerant charge: After replacing the compressor, the refrigerant in the air conditioning system has been drained, so the technician needs to recharge the refrigerant according to the manufacturer's specifications. This often requires the use of special tools and equipment to ensure proper filling.

7. Verify system operation: Once the refrigerant charge is complete, the technician will test and confirm that the AC system is operating properly. They will check various functions of the air conditioner, such as the amount of air being blown out and the temperature, to make sure everything is working properly.

This is the rough AC compressor replacement process. Remember, before any air conditioning system repair or replacement work is performed, it is best to have it performed by a professional air conditioning technician to ensure the work is done safely and correctly.

Identify The Problem

There are many AC compressor problems and solutions, but by properly identifying the source of the problem, we can narrow down the possible causes. The AC compressor is powered by a drive belt, which means it has a pulley to transfer power to the unit. Since the AC does not need to be running all the time, the compressor has a clutch that allows the pulley to spin freely without powering the unit. When you turn on the air conditioner, the electromagnetic compressor clutch receives a start signal. The component mounted on the compressor generates a magnetic field current that attracts the external clutch disc toward it. The disc then merges with the compressor shaft and the pulley begins transmitting power to the compressor. You can tell by looking at the compressor pulley and clutch plate - if both are turning, that means the clutch is working properly and the compressor is receiving power. However, if the pulley rotates and the clutch plate remains stationary, the clutch is not working properly.
