Here is another project I had in the shop, replacing an air conditioner clutch bearing in a 2002 Chevrolet Duramax. Thanks for watching, and please subscribe!
Mike. Great job. Thank you for posting this video. I had this same problem on my 1997 Chevy S-10. I followed your instruction and successfully replaced the AC clutch assembly myself.
I had to replace my clutch kit as for some reason the bolt fell out and then the splines were destroy on the outer clutch plate. Anyways it was a 2015. The biggest advantage you will give your self when servicing the clutch is remove the 4 compressor main bolts that attach it to the engine. It will allow you to turn the whole AC upward allowing you a far better way of working on it. Also, remove the main rad hose to get it out of the way. Doing this simple step allowed access to the ring clips, kept from losing any of the washers etc. A nightmare without keeping the AC in place.
2015 Duramax? My 2016 LML duramax the bolt came out but the magnet held on to the pulley. It’s a reverse thread bolt. Fix that last year and now the compressor just took a dump today. Good thing I have one in the garage, but still wtf..
Hello. Thanks for the nice video. My car is Fiat Bravo 2008 1.6 diesel and since I have it I have issues with unstable rough idle, more noticeable in the summer. I tried a lot of thing with this car and no improvement, visited a lot of mechanics, diagnostics etc and nobody can't find the issue. Having in mind that the rough idle is more noticeable in the summer I started to think if there is a problem with my air conditioning and more specifically sticking AC clutch or something like this. Last 1-2 weeks my car was working fine (I am not using AC anymore as it is not hot), so a few days ago I turned on the AC and I didn't noticed any issue, but after around 20 minutes I had to drive my car again and after starting it again the rough idle was there again. So is it possible my AC clutch to be sticking for some reason even after the AC is turned off and this to cause the rough idle? Thanks in advance!
I didn’t replace the OEM assembly. I had ordered an OE replacement from my local NAPA but it was incorrect so I just ordered the replacement bearing. I found the bearing on Amazon. AC Compressor Clutch Bearing Brand: VXB P/N: 35BD5222 SKU: Kit17200 Mike
That is not actually part of the compressor. That is part of the suction/discharge hose and manifold assembly. It's like a drier, think of it as catching the last possible bit of liquid refrigerant coming from the evaporator and accumulator before it can enter the compressor.
Thanks. I've done the heat/cool components as well. In the industrial industry that I have worked in for nearly 30 years now I generally use a bearing heater but for light interference fits as long as you press on the correct part of the bearing you are safe and not inducing any damaging forces into the bearing. Thanks for watching the video. Mike.
Yes, the nut on the shaft must be removed, then the puller is threaded into the bore of the clutch hub and presses against the compressor shaft which in turn presses the clutch hub off. Mike.
I have a 2002 GMC Sierra 2500 HD Duramax and I have been trying to find a AC Clutch coil I’m not sure there is an actual replacement for this specific model of AC compressor. The delphi 7067 is virtually impossible to find.
Yeah, I couldn't find the clutch/coil/bearing assembly which is why I replaced the bearings separately. I'm not positive but I think you have to purchase a complete compressor to get the clutch components. Good luck and thank you for watching. Mike
@@zmotorsports62 that’s what it’s starting to look like. Have one last place I’m waiting for a return call from. It’s a Duramax salvage yard in Hicksville Ohio. It’s possible they will have one. But my coil is the part that’s bad not my clutch. Very well put together video. Thanks for replying.
I’ve got the same exact compressor and clutch. I would assume if the out side part of the clutch won’t spin freely, nor engage the compressor, then my compressor is frozen and needs to be replaced?
@@zmotorsports62 no, that part spins freely with the serpentine belt. It’s the clutch part that engages the compressor that won’t spin, I’m assuming it’s the compressor itself that’s frozen if the outside part doesn’t spin
@@zmotorsports62 okay, I thought so, I just wasn’t a hundred percent sure. I really appreciate you responding, especially since this video was 8 years ago!! Thanks!
If memory serves there were two variations. One was available and one was not. This one was not available as an assembly which was why we had to source the bearing and purchase it separately. You’ll have to see which one you have. Mike
@@zmotorsports62 your memory serves you well. After a couple hours scouring the net and making calls I was finally able to get a solid answer from Delphi, maker of the "AC Delco" compressor with the 3 eye hub. From 01 to 03 GM decided to use two different compressors for the 2500HD (as well as others) The Delphi and a Denso compressor. If you are fortunate enough to have thw Denso compressor the Four Seasons clutch kit will work for you. If you have the Delphi you are OUT OF LUCK for ANY new parts support. Trust me I looked everywhere. The only two options if you want to keep your Delphi pump is to scavange parts from a donor rig or buy a complete Delphi compressor. Yup you can get a brand spankin new Delphi with a brand spankin new clutch but you cant just buy the clutch. Anyhow, thanks for the video. This was super helpful as I am about to change a bearing as well
Thanks. I didn’t give the bearing part # because there are two different compressors/clutch’s available and didn’t want to confuse people and have them order the wrong bearings before they tear theirs apart and determine exactly what bearing is needed. Thanks for watching. Mike
@@zmotorsports62 ah shoot. Had a feeling. Can’t find anything online. Just did a new compressor on my lb7 and the plug was old. The one I got from Napa had the wires switched
@@zmotorsports62 so I brought my good multimeter from work home. Tested continuity and got the correct ground wire. I had the two switched for about a 3 months. Not sure how the ac worked. The pigtail plug I got from Napa had the wires switched, and everything in me did not want to splice from black to green on the pigtail. Hope I didn’t mess the brand new clutch/compressor up
If it makes noise when the clutch is engaged it is internal or locked up obviously or if you lose your refrigerant charge it can be the compressor seal. Thanks for watching. Mike
Joselino Liaz you can purchase them from most tool companies/vendors of various quality. The set I have I purchased from my local NAPA store a few years ago and it has been a very good set. A little tip no matter which brand you purchase is to put a little oil on the threads to help reduce the friction and prolong the life of the tool. Actually I do this on all of pullers and have had excellent results compared to co-workers who use nothing. Thanks for watching. Mike
Why didn’t you show the complete reinstall of the clutch? You cut to it being done after the tool wouldn’t thread up. Also, why did you demonstrate the slop in the bearing AFTER you pressed it out from the center?
Roland Weeds you can get them from most tool companies/vendors. I purchased mine from my local NAPA store and it has been a good quality set. Thanks for watching. Mike.
Sounds more to me like its low on refrigerant and the low pressure switch is causing the clutch to cycle. You’ll have to throw some gauges on it to verify though. Mike
Excellent video. A truly talented master mechanic.
Thank you and thanks for watching. Please be sure to check out some of my other project videos.

Nice vid... love the lawnmower melody
Mike. Great job. Thank you for posting this video. I had this same problem on my 1997 Chevy S-10. I followed your instruction and successfully replaced the AC clutch assembly myself.
blueshere4u Great. Glad to hear the video was of some benefit to you and you had success replacing you clutch assembly.
Mike.
Great video good to see it done the old way instead of swapping out the whole compressor like most people do.
+John V thank you. I appreciate your comment and glad you found it helpful.
Thanks for watching.
Mike
Great and very informative video... Most auto parts will loan out the removal and install set...
+Rick Snowden yes they will.
Thanks for watching.

where can I find the oem clutch bearing assembly at? I can not seem to find it
I didn’t replace the OEM assembly. I had ordered an OE replacement from my local NAPA but it was incorrect so I just ordered the replacement bearing.
I found the bearing on Amazon.
AC Compressor Clutch Bearing
Brand: VXB
P/N: 35BD5222
SKU: Kit17200
Mike
Thanks a ton!
+Leo Bookman you're welcome. Thanks for watching.
Mike
I have a question what are the two cylinders over the A/C compressor?
That is not actually part of the compressor. That is part of the suction/discharge hose and manifold assembly. It's like a drier, think of it as catching the last possible bit of liquid refrigerant coming from the evaporator and accumulator before it can enter the compressor.
putting pulley in the sun on concrete,well in California and putting bearing in freezer for 15-20 min (just try it) no press no stress
Thanks. I've done the heat/cool components as well. In the industrial industry that I have worked in for nearly 30 years now I generally use a bearing heater but for light interference fits as long as you press on the correct part of the bearing you are safe and not inducing any damaging forces into the bearing.
Thanks for watching the video.
Mike.
My electro magnet failed and i cant find a replacement anywhere
Maybe this is a dumb question, but did you take a nut off before you pulled the ac hub off?
Yes, the nut on the shaft must be removed, then the puller is threaded into the bore of the clutch hub and presses against the compressor shaft which in turn presses the clutch hub off.
Mike.

Great video. Just wanted to know the part number for the baring or size of the baring you used.
Thank you for watching. If memory serves the bearing number was a BCA 907257.
I’ve got the same exact compressor and clutch. I would assume if the out side part of the clutch won’t spin freely, nor engage the compressor, then my compressor is frozen and needs to be replaced?
If you are referring to the pulley where the belt runs then that would more than likely be the outer bearing if it won't turn.
@@zmotorsports62 no, that part spins freely with the serpentine belt. It’s the clutch part that engages the compressor that won’t spin, I’m assuming it’s the compressor itself that’s frozen if the outside part doesn’t spin
Yes, I think your compressor is toast.
@@zmotorsports62 okay, I thought so, I just wasn’t a hundred percent sure.
I really appreciate you responding, especially since this video was 8 years ago!! Thanks!
Is there an entire clutch kit available?

Glad to be of help. Your experience sounds very familiar. 🤔
Great video but I was hoping you gave the bearing part # I need to do this on my 08 duramax
Thanks. I didn’t give the bearing part # because there are two different compressors/clutch’s available and didn’t want to confuse people and have them order the wrong bearings before they tear theirs apart and determine exactly what bearing is needed.
Thanks for watching.
Mike
zmotorsports where do i source a kit for my 2006 duramax? And how do i tell which bearing i need?
I don’t know of any kits per se. I had to remove the bearings and match them up. No one showed the bearing numbers, not even the OEM.
Mike
The green/black wire plug on top. Which wire is positive? Green?
I'm sorry, I can't remember as it's been so long. That work was done 8-years ago.
Mike
@@zmotorsports62 ah shoot. Had a feeling. Can’t find anything online. Just did a new compressor on my lb7 and the plug was old. The one I got from Napa had the wires switched
Throw a meter on it and test each wire. One should go directly to ground and the positive should go through a switch/relay and have higher resistance.
@@zmotorsports62 so I brought my good multimeter from work home. Tested continuity and got the correct ground wire. I had the two switched for about a 3 months. Not sure how the ac worked. The pigtail plug I got from Napa had the wires switched, and everything in me did not want to splice from black to green on the pigtail. Hope I didn’t mess the brand new clutch/compressor up
question... how would you know if the compressor was shot ? other than its locked up
If it makes noise when the clutch is engaged it is internal or locked up obviously or if you lose your refrigerant charge it can be the compressor seal.
Thanks for watching.
Mike
I watched the whole video mainly to see how to put clutch on and adjust the gap.
Hope it was helpful. Thank you for watching.
Mike
where can you buy the removal tools?
Joselino Liaz you can purchase them from most tool companies/vendors of various quality. The set I have I purchased from my local NAPA store a few years ago and it has been a very good set. A little tip no matter which brand you purchase is to put a little oil on the threads to help reduce the friction and prolong the life of the tool. Actually I do this on all of pullers and have had excellent results compared to co-workers who use nothing.
Thanks for watching.
Mike
does it worth.take it to a Mecanic just to change a clutch .& end up paying more than a new compresor with the clutch on it ?
way less time ,, and when you break the system you should replace the seals, and the drier so my guess would be way cheaper to replace clutch assemble
Why didn’t you show the complete reinstall of the clutch? You cut to it being done after the tool wouldn’t thread up. Also, why did you demonstrate the slop in the bearing AFTER you pressed it out from the center?
Sorry. I was having technical difficulties with the camera during the reinstallation but didn’t think to show the bearing slop after removal.
Where did you find the bearing?
Roland Weeds you can get them from most tool companies/vendors. I purchased mine from my local NAPA store and it has been a good quality set.
Thanks for watching.
Mike.
I found that napa has a large selection of bearings,,, and you can just wheel it in and let them measure
Checked my local NAPA, they didn’t have it. They didn’t list it nor could they match it up by the specifications so I had to dig deeper.
Mike
What is the toool called ?
A/C compressor clutch puller and installer.
Thanks for watching.
Mike
In my 03 2500HD the A/C clutch is engaging for four seconds, then off for six to seven seconds. Should the clutch be replaced?
Sounds more to me like its low on refrigerant and the low pressure switch is causing the clutch to cycle. You’ll have to throw some gauges on it to verify though.
Mike
@@zmotorsports62 Thank you. Means I must have a leak somewhere
