I have a 2007 x type diesel has anyone replaced the bearing inside the clutch assembly on the air con pulley. If so can you tell me the size of bearing. Plus how to remove the pulley.

 

Generally the clutch is sold with a complete a/c compressor. I don't know of an available clutch only. The removal of the clutch is fairly straight forward there is a nut on the end of the shaft. Remove it and install a clam shell type puller and you should be able to remove the clutch. There is a spacer behind the clutch be sure not to lose it.
Mainly the whole a/c compressor, if you shop around, is pretty cheap as a unit. Not really much need to go to the effort of changing a bearing only to find other problems with the clutch.

 

the nut allows the removal of the clutch plate, under this is a cir-clip that holds the pulley unit. the pulley will just pull off once this is removed. under the pulley there is another cir clip that holds the clutch coil assembly. I've just taken one apart as the pulley had broken away from the centre part that holds the bearing.

 

Thank you for the information very helpful. I have with much searching found a replacement bearing if anyone interested it's a (NSK bearing FS10 visteon) size 30/55/23

 

if your only changing the pully bearing then it should be a simple job if your changing the bearing in the compressor then its a major job and you would be better getting a known good compressor from a scrapper.
