Clutch Bearing

Railroader on Sat February 07, 2009 7:22 PM User is offline

Year: 1992
Make: Buick
Model: Century
Engine Size: 3.0
Refrigerant Type: R-12
Country of Origin: United States

My daughter's compressor clutch pulley appears to be making a lot of noise, can one just replace the bearing, and where can I purchase one, I might add she is financially embarrassed, I have compressor tools. Thanks

Just e-mail the guys at Ackits.com they have them in stock. One size bearing for GM from the 60's on up.. I have the delco number somewhere, if you need it, but they do have them..After you remove the pully you'll see three "pean" marks holding the bearing in the pulley, you have grind away, (die grinder works well) unless you have a press, then knock the bearing out, don't distort the pulley, then tap the new one in..it's not hard at all..

The AcDelco Part Number is: 15-2802 You can give that number when you e-mail the guys at Ackits.com..Hope this helps..

Here's an old pic I found of a GM bearing, there are more than three pean marks on GM.. Sorry...

But they grind out easily.. Hope this helps..

Just make sure it is not as simple as the clutch dragging on the pulley face- all that requires is an air gap widening. Spin the pulley to be sure of the source of noise.

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Yeah, good point, if you have the 2.5 engine it uses the V5 compressor, very common for clutch drag, if the 3.3, it uses the H series, still can happen, there isn't a 3.0 as you have listed, so either way, if it's a clutch drag, just use your tools to widen the gap a bit...hope this helps..

Thanks for all the Info, will look at it all

Sorry for the mistake, it's a 3.3 engine

I have one more question, does this compressor have a nut on the end of the shaft of the clutch assembly. I am trying to take the clutch off without removing the compressor, and I can't see in the end of the clutch very well. Thanks

Most likely it will not have a nut on the shaft as they are pressed on so you will have to remove the compressor for best results w/o pulling out your hair! Hope this helps and good luck!!!

A '92 will most likely have a nut, around 1/2" or 9/16" I believe.. I can't remember the year GM did away with the nut, but you do have to be sure..You can break the shaft if you try to remove the hub without removing the nut first, use a thin wall socket to test, or a mirror to look inside..... Hope this helps..


This is a pic of a pretty rusty nose, but you can see it's in there...

If OEM compressor- a '92 H series compressor will have a nut.....was removed in '94 as I recall.....

Thought 1992 was the cut off date.... Iether way you will still need to drop the compressor.
