The picture on the right shows the front of the pulley which has a friction surface for the clutch. Some of the accessories hanging on the front of the engine use bushings and others use roller bearings. It's best to use the universal puller. Note, the compressor ran pretty good quiet and had cool air for a number of years. The bearing in my compressor was worn out. We frequently receive systematic training from professional consulting organizations and keep a sustainable growing of group skills.
If it moves around the bearings and seal are probably bad and no need to just replace the clutch. Our Company is a professional manufacturer of automotive air conditioning industry. We checked everything related to the turbo and couldn't find any leaks or problems. It involves special tools to do correctly. If you bought your truck used you really won't know the history. Here's what one of my readers found.
I was out in Colorado in September of 04 and I heard a new louder noise. The top part of the tool chest serves as a storage area for fittings and air conditioning test equipment. The top part of the tool chest serves as a storage area for fittings and air conditioning test equipment. If you don't have the puller or forgot to bring it like we did bolt the compressor back down to it's mount and carefully pry the pulley away from the compressor. I feel I could do another one now in half the time or less. It has become necessary to keep the troll attacks to a minimum.
Be extra careful putting the new one on, it has a seal with a brass ring that needs to be pushed on. A big note, when you get the clutch off put the tool back on and try and move the shaft up and down and sideways. Checked for leaks with a light and the only leak that I could find was the clutch area of the compressor. Even if I would have been successful in installing the clutch the compressor would have failed shortly thereafter. I listened to the noise with a mechanics stethoscope and determined that the noise was either coming from the air conditioning compressor pulley bearing or the belt tensioner. The coil is a circular electro magnet that pulls the clutch in and activates the compresser. The second part of the saga was my quest for finding the part at the right price.
After worrying about it I found out that some clutches are solid right and some are a flex plate left design and are interchangeable. I called a Hummer dealer and they said that they never just replace the bearing. But, it started losing refrigerant last year. While trying to get the coil off I removed a snap ring inside the hub which was holding the seal causing all the gas in the system to blow out; so be careful. It sounded exactly like turbo whine. He said that it was just serviced a couple of months ago but isn't working.
They said that they replace the whole compressor because they found that in many cases once they replaced the front bearing the compressor went soon after, making for very unhappy customers. I listened to the noise and determined it wasn't the power steering pump. A bad bushing will 'scream' or 'screech' while a bearing will make a 'whirring' or grinding sound. Sorry for digging up an old post but this post related exactly to what I think I need to do. If I had the whole compressor replaced It would have cost at least 1,000. This was traced to a failed vacuum pump.
It adjusts its pumping volume to accommodate varying cooling loads and engine speeds. After taking the clutch off one of my friends told me to check the main bearing in the compressor by moving the shaft up and down. I felt that there probably wasn't much wear on the compressor so I decided to replace the bearing. I assume it's the shaft seal and according to the parts page the impala also has the harrison v5 compressor. Good job documenting the above.
He said he didn't have the puller set. I am sure I made some mistakes and there are likely better ways to do some things. I am sorry for this, and I know it slows down the discussion. How you do it Remove the serpentine belt and unbolt the compressor from it's mounts and tilt it up so you can get to the front easier. I thought I'd be able to find a shop that could just throw the pulley on for me and I'd be done. I was going to order them but I knew that I'd probably use them once and I didn't want to wait anymore. I found that most all shops wanted to replace the whole compressor and all the associated parts for a considerable amount of money.
Bushings and Bearings make different noises. If it's on 10 days a year that would be a lot. I was told to make the air gap between the clutch and the pulley assembly between 20-30 thousands. . I did not drain and measure how much oil came out of the old accumulator. If this site has helped you consider a Donation. I stopped at a few independent places and each one said that they didn't have the special tools.
This is not a simple job for inexperienced mechanics. Tools are stored in a sturdy tool chest 92275 and organized in two drawers with a chart showing which tools are used for a specific compressor. Complete kits with all the pullers and tools ran from 60 to 300 depending on the quality. If more mechanics would fix these, they would soon see that they can make much more of a profit by not buying a new compressor. The part arrived the following week. I now have a decent understanding of all the parts in the ac system.
