Xantia .. Noisy Aircon Compressor Pulley

Post by KevMayer »

Hello chaps,
My 1.9 turboD Xantia has had a noisy aircon pulley for years. It really whines when the clutch is not engaged. Switch the aircon on, the clutch engages and the noise goes away.
I've had enough, so, am thinking of getting a new compressor. This means I need a regas as well. Not a DIY job obviously. Unless I could change the bearing in the pulley. The problem being that the rolley/pulley wheel of the compressor catches on the clutch disc when the clutch is not engaged. Engage the clutch and the two are locked together, so no whining noise. I think a new pulley bearing would do the job.
Has anyone had any experience of this whining noise ?
Has anyone ever changed the compressor pulley bearing (can it be done) ?
cheers

I had the same problem on my 1997 Xantia, unfortunately I ended up have to buy a compressor, total cost £385.00(inc fittting and charging). The problem was that the compressor listed was not the one on the car It turned out that that it was actually from a citroen van with aircon. The make of the compressor by the way was was Harrison.
Good luck

My compressor is a Harrison.
I have contacted my local Citroen specialist and he says he has worked on these before. He is going to change the clutch assembly for me.
I tried to get the clutch plate off myself. I undid the centre nut, but the plate would not move.
The specialist I have spoken to says he made up a special tool to 'pull' the clutch and armature off. You can get new clutch/pulley assemblies for these compressors.

Hi Kev
How did you get on with the pulley/clutch? I have been trying to source bits for mine (Delphi/Harrison) for some time. A second hand compressor I located was the wrong type.
BTW, the clutch assembley has an internal thread on the outer plate. The tool required is like a large version of a bicycle crank removal tool with an external threaded bush and central threaded bolt.

Today I had my pulley/clutch changed by my local Citroen specialist.
It was a Harrison compressor and the bits cost £238.00 for the pulley/clutch assembly.
I was told that a new compressor would cost more than twice as much.
It is so quiet now. I can just about hear the clutch pull in if I stick my head out of the open window. It cost more than I expected, but I couldn't have done it and its cheaper than getting a new car.
I still enjoy my Xantia a lot.

Hi Kev. Glad you got the problem solved. I eventually located a second hand compressor from somewhere near Macclesfield. Had been on the donor car for some 5000 miles and appears to be a good 'un. Cost was reasonable. De-gas and re-gas cost more than expected, though. But that seems to be the case with everything - or am I just becoming older and more cynical?
Happy freezing.
