the bearing in my a/c compressor went bad and was wondering if anyone had replaced this themselves. If so is it a easy job to do? I tryed to search this but no posts came up on replacing a bearing on the a/c compressor. I mean i can probly figure it out on my own but i would like to know what im in for on the labor part...

thanks, colton

 

Are you sure it wasn't the clutch bearing that's gone south?

 

have been in the middle of the same thing. I determined that it was the clutch bearing that had locked up. With heat and age arrives motivation. Mine is a 22re, I wonder if the compressors are the same? Anyway, dropped the compressor, removed the center bolt, not thinking it was repaireable (exploratory surgery you know) I beat the pulley off from the rear, turned out ok but not recommended. Long story short, bought a new bearing on ebay for $19.00. Bearing identification: Looking at the bearing, at 12 oclock says (134), at 4 oclock says (NSK), at 7 oclock says (30BD5222DUM6). Perfect fit, also bought a new coil/stator but it has no identification from the same ebayer. The only problem I had was the spacing of the clutch face to the coil, it was too close and stayed engaged. I took it off and added a little washer under the pulley (the center bolt goes through it) to increase the spacing. Works fine now.

Just copied a post that I made yesterday. Mine is a 22re.

yeahh i thought it was the idler pully at first making a growling noise but after i replaced the idler pully the noise did go away soo i left the belt loose started the truck and flicked the ac on and the noise stopped so i looked under the hood and the ac compresser wasnt spinning (while the motor was running) so i turned the truck off and felt the pully on the compressor and it had back n forth play to it

 

It sounds like the clutch bearing. Hope so because you really should not change the compressor without AC equipment.

Your signature says you have a 94. It might have the older R12 coolant. If so, if you open the AC system you will have to convert it to R134a, since you can't get R12. Not a real hard job but you need AC tools (mostly a vacuum pump) to do it.

 

Yeah I have r134 (thank god) and I had it recently recharged and a leak test done and there was no leaks to be found. The ac works really good minus the growling noice

 

I have been wheeling about town blilly happy with myself for fixing my air at very little cost. I had just glanced at the thermo in the vent thinking about the high number of brain cells that I must have, then, I noticed the smoke. Pulled over raised the hood, might have even seen a small flame at the compressor belt. Damn!! So, that was the end of that. Now looking for a compressor. That must have been my 15 minutes of fame. Have not taken it off yet for the post mortom, just cut the belt.
