Read through my post here: https://xoutpost.com/bmw-sav-forums/...pair-help.html

You can see the options that you can use.


Thank you sir. My AC works really well! Both driver, passenger and back. I had a look and the piece that’s pictured in yellow was the piece that was vibrating and looked like the culprit. I’m def going to check the pulley because I’ll be in there so I might as well.
Thank you

Can you at least post a picture of the front of the compressor? Like I said in my other posts, sure seems like the same problem I had with the bearing failure.

I think it’s definitely the pulley only. I think the compressor is ok still because up until this complete failure. It was blowing arctic. I’m struggling to get the center T30? (I forgot) bolt out because it spins freely. And the same goes for the three bolts because the pulley spins freely too...
The bearing itself is completely gone. It must of blown up... I got a new compressor on the way. I’ll tackle this next week.

That front part with the pulley is the electro magnetic clutch. It can be changed on most makes without breaking into the A/C system charge. Its R134a, not freon by the way. It appears a weld broke. When power energizes the magnet, it pulls the pulley into engagement which then turns the compressor internally. Good luck.

Yup, my issue was exactly like yours and this clutch assembly worked perfectly! https://www.ebay.com/itm/NEW-A-C-Com...pe!95391!US!-1

Thank you Cuda, interesting how it works compared to others..
I’ve got a whole compressor coming but if I can’t get mine off then I’ll consider the pulley setup like you did 740 and possibly this kit. Thanks guys, I’m going to try take it off this weekend. I’ll update as I get news.

Just my $0.02, but I'd try removing the pulley and race first, instead of the compressor. That way if you're successful, you won't have to evacuate and recharge the system.

To keep the pulley from turning, I used a strap wrench on mine and it worked perfectly.

Look forward to your results.

Yea I think that’s a good idea, try the pulley first. I got a puller so hopefully I’ll have space in there.. strap sounds like it’s the way to go!
