Buyer's Guide
If you have an older car, chances are you probably own a compressor clutch. These clutches help keep your engine running smoothly by preventing the pistons from moving too quickly, thus reducing wear and tear on the engine. However, they also require regular maintenance, as well as replacing every few years.
An air conditioning compressor clutch is an important part of any air conditioning system. It allows the motor to turn freely without damaging the compressor if the power goes off for some reason. The compressor clutch is located inside the compressor housing where the motor shaft connects to the impeller. If the compressor clutch does not work properly, the compressor will continue running even though there is no power coming into the unit. This could damage the compressor and cause expensive repairs.
The manufacturer recommends that you replace your compressor clutch every five years. However, this depends on how much time has passed since the last repair was performed. You may want to consider having your clutch replaced sooner than recommended if you notice any unusual noises coming from the compressor. These sounds could indicate problems with the clutch.
Your air conditioning system uses a compressor to move refrigerant through coils inside your home. These coils allow cool air to enter your house and warm air to exit. Without these coils, your AC would only run part time.
The compressor is the heart of this system. It turns on and off based on how cold outside temperatures are. Then, the liquid goes back into the coil where it evaporates again. As it evaporates, heat is released which makes the air around us cooler.
This process repeats itself over and over again every hour. But sometimes, the compressor gets stuck. This happens when the oil level drops below a certain point. At this point, the compressor doesn't start turning on anymore. Instead, it starts vibrating and shaking. This is called clutch lockup.
When this happens, you can still use your AC. However, it won't function properly. Your unit could continue running but the temperature will fluctuate wildly. Sometimes, it can take several days before the problem clears up.
To avoid this situation, you should check the oil levels in your compressor once a month. To do this, remove the cover plate located near the top of the compressor. Look for two tubes filled with oil. One tube should be labeled oil while the other one should say filter.
Check the oil levels in each tube. If either one has become empty, then you need to change the filter. Otherwise, you'll need to add new oil.
Once you've done this, put everything back together. Turn on the power switch and let the compressor run for a minute or two. Then, test the system. If it runs smoothly, you're ready to go.
However, if the compressor still isn't working right after doing this, call a professional. An HVAC technician can diagnose the issue quickly and fix it.
In addition to checking the oil levels, you should also inspect the compressor's bearings. If any of these look worn, you should replace them. Bearings are usually covered by a plastic cap. Remove this cap and see if anything looks loose. If so, tighten it down.
Finally, you should clean the fins on the compressor. This ensures that the fan blades spin freely. If the fins aren't cleaned, they can cause damage to the compressor. Cleaning them takes very little effort.
If you have an older car, chances are you've had trouble finding a reliable source for a new ac compressor clutch. This is because many manufacturers stopped making them years ago. Fortunately, we now have plenty of choices available to us. So if you want to purchase a quality ac compressor clutch, here are some things to keep in mind:
Look for a clutch that is rated for your vehicle. You'll find different ratings depending on whether your vehicle is front engine or rear wheel drive. For example, most vehicles manufactured after 1996 use a "B" rating. A B rating means that the clutch should work properly up until about 10 years old. After that point, it may begin to wear down faster. On the other hand, a C rating means that the clutch should last up to 15 years. A D rating means that the clutch should last 20 years or more. Make sure that the clutch you buy matches the rating of your vehicle.
Consider how often you plan on driving your vehicle. Clutch life depends on how frequently you drive your vehicle. If you rarely drive your vehicle, then you probably won't notice any difference between clutches that last 10 years versus those that last 30 years. However, if you regularly drive your vehicle, then you'll likely see a big difference between clutches that last 10 years versus those that last 30 years.
Also, consider how heavy your vehicle is. Heavy vehicles tend to generate more heat than light vehicles. Heat affects the performance of clutches. When a clutch gets hot, it tends to slip less easily. Thus, you might notice that a clutch that works fine one day starts slipping more quickly the next day. If you plan on keeping your vehicle for several years, then you'll want to invest in a clutch that will last for decades rather than just a couple of years.
Finally, consider the type of driving conditions you typically encounter. Driving in cold weather can shorten the lifespan of a clutch. Likewise, driving through rain or snow can damage a clutch.
Compressor clutches. When you're replacing a compressor clutch, you'll want to make sure it has everything you need to do the job right. Here are three features to look for:
Clutch design. The first feature to check is the clutch design. Clutches come in two basic designs: spring-loaded and centrifugal. Spring-loaded clutches work well if you plan to run your compressor only occasionally. Centrifugal clutches work well if you plan to run your compressor regularly.
Clutch material. Next, look for the type of material used to build the clutch. Some clutches are made of metal, while others are made of rubber. Rubber clutches tend to wear faster than metal ones, so they may not hold up as well over time.
Clutch mounting system. Finally, pay attention to how the clutch mounts to the motor shaft. Make sure there's enough clearance between the clutch and the motor shaft so the clutch doesn't bind during operation.
Conditioning. After you've replaced the compressor clutch, you'll want to give it a thorough conditioning period. This lets the new clutch settle into place and reduces the chance of noise and vibration issues.
If you're planning to install a new compressor clutch, here are a few tips to keep in mind:
Keep the old compressor running until the new clutch is installed. This allows the new clutch to cool down and prevents overheating.
Install the new clutch using the correct torque specs. Don't overtighten the bolts; instead, tighten them just enough to secure the clutch properly.
Use the proper tools. Use the appropriate tool for the task. For example, a wrench set is ideal for tightening the compressor clutch nut, while a socket set is needed for removing the compressor clutch.
Give the compressor a full tuneup. Once the compressor clutch is installed, you'll want to perform a complete tuneup to ensure the compressor runs smoothly.
When it comes to air conditioning compressors, there are two main types. One is a centrifugal type and the other is a scroll type. Both types use a clutch to control how fast the motor spins. A centrifugal clutch uses friction plates to engage and disengage the motor. Scroll clutches use springs to engage and disengage the motor.
Centrifugal Clutch. Centrifugal clutches are the oldest style of clutch. They were invented by James Watt in 1769. They consist of a series of discs that spin against each other. When the discs touch, they create friction and stop the motor spinning. To start the motor again, the discs separate allowing the motor to turn freely.
Scroll Clutches. Scroll clutches were developed later. They were patented in 1891 by William J. Deane. They consist of a spiral shaped spring that engages and disengages the motor. The spring is attached to a shaft that rotates with the motor. When the spring touches the shaft, it causes the motor to rotate. When the spring releases the shaft, the motor stops turning.
Both types of clutches have advantages and disadvantages. For example, centrifugal clutches are cheaper and easier to install. They also last longer. On the flip side, scroll clutches are quieter and more efficient. They also cost less to maintain.
If you own a centrifugal clutch, you should check its wear levels regularly. If it’s worn down, you could experience problems with the unit. If you own a scroll clutch, you should clean the dust off the parts every few months. Otherwise, you risk damaging the unit.
