How To Change Clutch On A/C Compressor

A/C compressors are critical pieces of equipment in any building. They help to keep us comfortable in the summer and cool in the winter, so it’s essential that they work properly. And if something goes wrong with them, you don’t want to have to deal with it yourself. Fortunately, there are a few simple steps you can take to change a clutch on an A/C compressor yourself. This guide will teach you everything you need to know so that you can fix your unit without having to call a professional. ###

What is a Clutch?

A clutch is a mechanism that helps to disengage the drive belt from the compressor pulley. It also allows the compressor to spin more freely, which in turn allows it to produce more airflow. A clutch can become worn or broken, which can cause it to fail to properly engage the drive belt and thus decrease air flow. In order to replace a clutch on an A/C compressor, first make sure that the compressor is off and unplugged. Next, remove the cover plate that covers the clutch and compressors. There are typically three screws that need to be removed in order to do so. Once the cover plate is removed, you will see the clutch sitting on top of two gearboxes. The main gearbox sits atop a shaft that rotates as the clutch engages and disengages the drive belt from the pulley. The smaller gearbox sits inside of this main gearbox and controls how much power is sent to the motor when the clutch is engaged or disengaged. To replace a clutch on an A/C compressor, first remove both gearsets by unscrewing them using a Phillips head screwdriver (the largest size). Be careful not to lose any parts during this process. Next, remove the old clutch by unscrewing it using a hex nut and bolt (the smallest size). Make sure to clean all debris off of both gearsets before reinstalling them into their respective locations on the shafts. Reinstallation will require lining up both screws and torqueing

How Does a Clutch Work?

A clutch is a mechanism that helps to engage and disengage the drive shaft from the crankshaft of an engine. When starting or stopping the engine, the clutch is used to help control the power transmission to the wheels. The clutch is typically operated by a pedal, but some engines have automated clutches that are controlled electronically.

Symptoms of a Clutch Failure

Clutch failure is the most common cause of compressor failure in air conditioning equipment. The clutch engages and disengages the compressor blades, which creates motion and air conditioning. If the clutch fails, the blades will continue to turn, resulting in overheating and eventual engine damage.

There are a number of symptoms that may indicate a clutch failure:

-The fan will not turn on or off
-The compressor will not start or run
-The compressor is making loud noises

How to Change the Clutch on an A/C Compressor

If your air conditioning compressor clutch is sticking or not engaging, there are a few things you can do to fix the problem.

1. Remove the compressor cover.
2. If the clutch is white, clean it with a degreaser and a soft cloth. If the clutch is black, replace it with a new one.
3. Check the alignment of the clutch plates and clutch hub on both sides of the compressor using a straight edge or jaw jenny. Make sure that all of the teeth on each side are lined up so that when it engages, it will create enough friction to turn the compressor on. If one side is out of alignment, use a hammer and chisel to fix it until both plates and hub are in alignment.
4. Clean any debris from inside the clutch using brake cleaner or carburetor cleaner (depending on your model). This will help to reduce wear on the gears and other parts inside the clutch.
5. Apply lubricant to all moving surfaces inside of the clutch using a grease gun or an aerosol can of WD-40 (depending on your model).
