Can you drive with a locked up AC compressor?

Motorcraft YB-3109 AC Compressor Clutch Pulley Review:


YB-3109 AC Compressor Clutch Pulley by Motorcraft as promised, received. With a little coaxing, the old one came off; after cleaning the shaft, this one was installed. To facilitate installation, use a little grease or insecticide.



Dorman HELP AC Bypass Pulley 34191 Review:


My a/c clutch burned out, and I lacked the funds to buy the necessary tools to replace it without taking the car out of commission. So I choose to just skip it rather than shell out cash to have a business do it.1. it is lightweight2. has a washer to adjust the pulley if necessary.3. has several bushings to ensure appropriate sizing.4. is cheaper than replacing the air conditioner.1. Plastic pulley; for the money, it ought to be made of metal.2. I had to use washers to hold the "plate" tightly to the motor because the bolts were a little too long for my 1997 Ford Crown Victoria. They ought to have had some for this reason.



Dorman HELP AC Bypass Pulley 34152 Review:


I had no idea this existed. I came upon it when looking up instructions on how to service my compressor clutch.Instead, I installed the Dorman bypass and took the AC out of my 1994 GMC Sonoma. The AC was never even utilised by me.Oh my god. Simple to install, enhanced horsepower, and 1-2 MPG better fuel economy. Even though the AC wasn't even running, the ancient compressor produced a lot of "engine drag."simple to install took a little under an hour.



Dorman 34174 HELP! Air Conditioning Bypass Pulley Review:


For the product, five stars. Amazon's delivery container only gets one star! This was one of three goods that were shipped to me, and by the time it reached at my place, it had been removed from its box. The bag with the related hardware was fortunate to still be there. No accidently breaking the plastic pulley!On my 1997 Vortec 5.7L 350, this A/C bypass pulley fitted up to the power steering/A/C compressor bracket nicely. With the pulley is a bag of mounting supplies: There are two sets of three 1.5" long bolts in two different sizes for a total of six bolts. For use with the smaller size bolts to ensure a good centered location once attached, hardware also includes bushing sleeves. With the 5.7L application, bushing sleeves are not required. Another option for positioning the pulley in relation to the other pulleys on your engine is to place a pulley spacer ring behind it.Overall, a fantastic product at a fantastic price!



Dorman HELP AC Bypass Pulley 34157 Review:


My 1989 GMC K1500 5.7L freon air conditioner hasn't worked in decades. Fix implies complete replacement of everything, hence it is (and has long been 2-55 AC, roll down 2 windows and go 55). discarded the entire AC dead weight. The bypass was precisely aligned, but the mount plate needed to be ground to make room for the bypass pulley because it was thicker at the back. I prefer an aluminium pulley over a plastic one.



Dorman 34239 Air Conditioning Bypass Pulley Review:


In the end, I chose to purchase a shorter 55-7/8" belt for my 2004 CR-V rather than shell out over $300 to have a shop deal with rusted bolts in order to install this, but this pulley still seems great. There is no play, wobble, or grinding in the pulley, and the base looks beautiful (runs smooth as you could want). Since some reviewers seem to believe that this isn't good enough, I feel compelled to bring it up. If only getting a shorter belt were quicker and less expensive, I would have used this product without hesitation.



Dorman HELP AC Bypass Pulley 34209 Review:


There are many sets of fasteners and pulley spacers. The accompanying bolts were inappropriate for my application, so I had to use one of the spacers to move the pulley "out" so that it would align with the belt. The pulley had grown in size from the original, necessitating a longer belt. I had to ream out the threaded mounts and install the old compressor bolts (they are sold in about 1/2" increments). The HD-6 compressor will be replaced by this, but "engineering" may be necessary.



Dorman HELP AC Bypass Pulley 34184 Review:


I perused a few of the product evaluations. My experience: I fitted this pulley using the shorter sleeves that were provided, but I soon discovered that it was out of alignment with the other pulleys. The one shiny metal washer in the group caught my attention. I took out the pulley wheel itself, put this washer—which, as it turns out, is a spacer—onto the spindle, and then put it back in. she was fired up. Everything is good but the squeaking I was trying to hide from. Okay, I hit the belt tensioner and took the belt off once more. I once more removed the pulley wheel. I used a sharp knife to remove the bearing seals and lubricated every moving part of the object, including the balls. reinstalled the belt after reinstalling the pulley (with washers for the bolts). she was fired up. Still making noise. Okay, I made the decision to ride this out and put 15-20 miles on my grease job. This stopped the rattling and squeaking.



Dorman HELP AC Bypass Pulley 34178 Review:


Okay, I'll confess it; I actually had to go purchase bolts and washers because the ones they provide are ineffective. Therefore, to make this work, I paid $3 at the hardware store. not angry My truck's engine failed, and my a/c compressor seized. This took me less than 30 minutes to install, and the truck is now running and silent once more.appears to be nicely crafted. I don't anticipate any issues.
