The model number wouldn't be much help with the bearing I suspect, the only parts PSA ever sold were either the complete compressor with clutch or the clutch/pulley/bearing as a unit. Your best shot is stripping the pulley off and looking for the number stamped onto the bearing itself either on the outer race or the shielding, format would be something like 6008ZZ or similar (not sure the exact number but should comply with the basic format, the numbers relate to size and the letters relate to sealing method). Ebay or local bearing factor should be able to help for under a tenner.
If you need the car driveable until you have the bearing let me know and i'll pop the one I have apart and get the bearing number for you.
Wow, that's really kind of you! Generally yes the car has to be back up and running Monday morning for the school run. To have a bearing ready for a Saturday would be good. If it's no trouble to "pop" apart though sure it's more complicated than that.

That's required the rear beam to be replaced wholesale (the subframe was tweaked and the trailing arm bearing sheared clean off) and currently sat with the rear quarter panel cut out and a replacement waiting in the garage till I get a chance to fit and weld it lol.
I'll have a shufty at it when I go out for a cigarette shortly, should just be a centre bolt, then maybe 3 holding the electrical coil part and the actual pulleys probably on a taper so tap 'em loose. Will get back when I've had a look, and will try and upload some pics too.
#33: Re: 206 PAS Pump Author: ekjdm14, Location: CheshirePosted: Tue Jan 21, 2020 10:54 am ---- That went well, pulley is off! Literally undo the centre nut (normal thread) and the clutch part is on a spline, just lifts off & then there's a circlip holding the main pulley & bearing on (toughest part as couldn't find circlip pliers, I just dug it out with a small screwdriver!).
Bearing number is a strange one to me, 35BD219DUK but they seem to have them for about 6 quid on ebay. (looking closer I might spend £20 or so on a decent SKF of NSK rather than a china special) Given how easy it is to check though I'd have a quick look at your compressor to ensure its the same one.
Main issue with actually replacing it is getting the old bearing out of the pulley, I'd probably find a socket or bit of strong tube that fits on the outer race of the bearing & then drift the old one out, to fit the new one without a press I'd want to draw it in squarely using something solid like a bit of 3/8" plate with a hole drilled in, socket or tube on outer race and some threaded rod or a long bolt & sandwich the lot together, tighten the bolt until the bearing is sat where the original one started from. I'll grab photos if you need anything clarified.

Thanks a million. I've access to a press so that shouldn't be an issue. Based on this I'll strip it first and take a look at the number.
#35: Re: 206 PAS Pump Author: clicon357, Location: KentPosted: Wed Jan 22, 2020 4:57 am ---- Looking last night, down through the open bonnet, I reckon I may be able to get the AC pulley off with the pump in situ once the car is up on the 2 poster. If that is mine comes off as easily as @ekjdm14's did.....which, knowing my luck it won't but got to be worth a try!
Won't be able to try for a couple of weeks probably (not my lift) but will report back when I do.
Cheers
#36: Re: 206 PAS Pump Author: ekjdm14, Location: CheshirePosted: Wed Jan 22, 2020 11:47 am ---- I have a feeling it'll be OK, the car my spare compressor is off was a rotter & the nut looked like it'd be a swine but actually came off without a fight. Under the clutch part is pretty well shielded so there's only likely to be friction dust to hinder you with the circlip.
I think it probably would come off with the pump in-situ, and maybe easier too since mine was rolling round on the floor! (as an idea how corroded the donor car was, the bolts holding the comp onto the engine in this case nearly snapped as I undid them & I nearly gave up removing it...) Glad I persevered now as it may have been useful
#37: Re: 206 PAS Pump Author: clicon357, Location: KentPosted: Sat Jan 25, 2020 7:26 am ---- Ekjdm14, on the AC, after you'd removed the clutch then the big circlip, did the pulley with bearing in just slide off or did you need a puller? Cheers.
#38: Re: 206 PAS Pump Author: ekjdm14, Location: CheshirePosted: Sat Jan 25, 2020 6:02 pm ---- Apologies for the late reply, it did come off pretty easily i.e. not a press fit although I did have to give it a sharp tap with a copper mallet before it moved.
#39: Re: 206 PAS Pump Author: clicon357, Location: KentPosted: Sat Feb 22, 2020 3:21 pm ---- Well it looks the whining noise is CURED!!!
Replaced the bearing. The old NSK one that came out:
I had to use a gear puller on the ribbed pulley to get it and the old bearing off. Couldn't find the medium and large puller, only the small and that wouldn't fit. In the end used an old Enerpac puller that I had to mod a bit with the grinder.
Tbh I just undid the 4 bolts (13mm socket) holding the compressor on and let it hang on the pipes as I couldn't get the puller on with the pump in situ.
Then a hydraulic press to push the old bearing out. You press from the side in the last picture. One weird thing is the bearing is retained by a shoulder on the side you press it out from and little pressed / crimped nibs on the back. As you push the bearing out you can't help but shear these nibs off. Once the bearing was back in I attempted to recreate these nibs with a hammer and punch. Should have taken a photo.
Used the hydraulic press again to push new bearing back in. It then went back onto the compressor shaft easy enough using a suitable size socket and hammer.
I say it's cured. I've not personally road tested it yet. Just as I was putting the wheel back on SWMBO came for my car key to go shopping so I just gave her hers and she took the Pug. Certainly the whine has gone. Should make it easier to hear the other noises now!
Thanks to all who helped on this.
Btw, does this forum allow uploading direct of pics rather than links? Last edited by clicon357 on Sun Feb 23, 2020 9:53 am; edited 4 times in total

#41: Re: 206 PAS Pump Whining - NOT! Author: ekjdm14, Location: CheshirePosted: Tue Feb 25, 2020 6:11 pm ---- Brilliant, glad that you got to the bottom of it now On the photos, if you go into the full reply box (rather than the quick reply box, just hit "preview" once you've typed a word or two.) Then, underneath the Bold, italic and underline buttons there's 3 methods to upload images, I use the middle one "upload image or photo from camera" and I can then select the photo on my computer & upload it.

Thanks. MOT to get through Monday!
#43: Re: 206 PAS Pump Whining - NOT! Author: clicon357, Location: KentPosted: Mon Mar 02, 2020 9:42 am ---- I spoke too soon on this noise! Whilst the loud whine / drone has gone there's now an underlying squeak/fluttering noise. I'm sure it's coming from the AC piulley / clutch I just replaced the bearing on. Not sure what I've done wrong but I need to strip it out again. Short video clip:
All I can think is I somehow bent the clutch part when I wedged it with the bfo flat blade screwdriver in order to strip it.
Saying that the pulley looks to be running eccentric but I'm sure the bearing pushed on square!
#44: Re: 206 PAS Pump Whining - NOT! Author: clicon357, Location: KentPosted: Tue Apr 14, 2020 10:54 am ---- Bit of an update and a faux pas on my part!
I cured the whining due to the old bearing. BUT...I ended up with a squeak.
What I'd done was managed to bend / deform the grooved pulley so it wasn't concentric to the centre bit of it that holds the bearing. Had to strip the compressor off again and press things back into shape on the 20T press. It really is actuallly properly quiet now.
