Play in AC clutch. Any cheap fixes?

[bebbetufs]

UPDATE: the noise is from the AC clutch/pulley assembly.

Ever since I changed the timing and aux belts I've had this sound, but lately it's been getting worse. It sounds like someone ringing a small bell or something hitting against some hollow metal part. It's a ting-ting-tingeling- ring-ting-tingelign-ishy sound. At first I put it down to a faulty auxiliary belt tensioner bearing (it was replaced but I may have gotten a bad part), but now I'm not sure.

I've had a listen around, and the auxiliary belt tensioner sounds like it does have a rough bearing, but I cant hear the tingeling sound through the stethoscope so I can't be sure.

I took my chances and elected not to replace rubber damped crank wheel for the timing belt, could it make such a noise? What are the symptoms of this failing?

I have not been able to listen to the AC compressor, so that too is a possible source.

TIA

what about disconnecting the aux belt for a few minutes and that would rule out air con pump/ belt tensioner ??

do this!

more than likely sounds like ac drive hub....

Thanks.

Thanks for the tips. I'll disconnect the belt this weekend and see what I find. Would not the sound change when AC is turned on/off if it was the Compressor?

Ok so I disconnected the belt and of course the noise is not from the esay-to-fix tensioner, but from the hard-to-get-at AC compressor

I would like to know of any cheap fixes or DIY solutions to this. Is there a way to simply bypass the AC? or can I change the clutch with a new one without having to remove the compressore with the associated work of evacuating the system and recharing?

Some more info on the AC.
*The bearing in the AC pulley is 2TS2-DF07A02Lx2. Here's one http://www.ebay.pl/itm/2TS2-DF07A02LX2-NTN-/291206147084
*The compressor is taken apart easily. The clutch plate is attached by one screw. It comes off easily. The pulley and the coil are attached by c-clips. No pullers are needed.
* The bearing needs to be pressed out. Some small locking notches need to be ground off before pressing. After pressing in a new bearing new locking notches must be punched. This will be obvious when you see it.

The problem in what turns out to be my remanufactured compressor (remanufactured in 2011) is that the coil has worked itself loose and was rattling like crazy behind the pulley. The coil is kept from rotating by a pin which locates in a hole in the compressor. In my case the coil has worked itself loose and the pin has worked itself through the front plate of the compressor. The only way i can fix this now is to try to JB weld a new coil onto the compressor and hope it lasts for a while. Obviously I wish I had tackled this sooner when the damage to the compressor would have been minimal.

great info!

if you can some pictures so other can take advantage of the possible fix for this
