How to change the air conditioner cluch bearing

are you refering to the clutch fork that connects to the other end of the clutch cable, you will have to drop the gear box as this fork sits over the clutch pressure plate ,and pushes the thrust bearing against the pressure plate tynes so disengages the drive from engine to gearbox, while you've got the box out check the condition of the clutch parts ie thrust bearing,pressure plate spring's,friction plate condition

Your system may be over or under serviced or you may have a bad low pressure switch. You need to post the year make and model of your car.

Try disconnecting battery for two minutes to reset the system. Then start the car and check a/c operation.

if the noise is only there when you push down the clutch, you need to replace the throw out bearing.

Usually the clutch can be replaced on those, but the bearings are too much to fix, by the time you pay for that repair you could have bought a new one, which is my recomendation. The alternative is a salvaged compressor. Thney are rarely why a car is put into the junkyard and usually work if installed correctly. Remember you have to vacuum down, and dehydrate a system that has been opened to the air before you can refill it.

I take it you have tried a new belt. The Air-conditioner belt driven clutch and bearing repair will cost you nearly as much as a re-conditoned unit. The time, effort and agony is just not worth the trouble of going through any clutch / bearing replacement attempt. (been there done that! And had the right tools!) Ended up replacing the compressor anyway as the internal rollers of the Compressor were the actual problem.

no, its not the transmisshion,,,, its the cluch release bearing worn out,
every time you press on the cluch it screems or chaters, yes?
you just need to fit a new cluch, as its realy not worth the effort in just replacing the bearing only to have the rest of the cluch go in 6 months
that would be mad ness and pricy

oh dear, you drive with your foot on the cluch then? or hold the cluch down at the lights insted of knocking it out of gear? never hold down the cluch for more that 30 seconds at a time,,,,,naughty naughty! this is just one of the prices you pay for that,
its you cluch release bearing, its seised up on you, cluch riding dose that! its only a little bearing!!!!!
the fix is a new cluch bearing, but what it costs to take the gear box out to replase the bearing it would be cheeper in the long run to have a compleat new cluch fitted, and then lurn not to ride the new cluch as much,,,,and all this just to pull away a fuw seconds faster??? this is a £350-£500 job now
how frustrated do you feel now?????

Try adding a can of freon, you might have a leak, the clutch will not work if not enough pressure in ac system

It might be your cluch on your commpressor pulley, start your engine,turn your ac on and check to see if the center of your pulley (cluch) is turning if is not, that your problem. I hope this helped.
