Just to let you all know. I changed my compressor clutch bearing and the electro magnet without removing the compressor from the car. And this guide is only from my memory of when I did it myself a few weeks ago so take it with a pinch of salt. I may have missed a few details out but will try my best to help you.
And only follow this guide when you have checked everything else and are certain that the electro magnetic clutch is at fault. Or if you have a noisey bearing.
I couldn't find a complete compressor clutch kit for a type r so used a various parts from another model.
Jump on ebay and get a compressor clutch kit for a 1.8 petrol. The pully wont fit but the electro magnet,locking nut and circlips will and it's only £12.95.
Then get a bearing. Delphi Sanden TRSE07 35x48x20mm. This is for your pully that you are going to remove from your car.
Then onto cox and order a shim kit. About 6 quid if I remember correctly.
Now you have all your parts you can start stripping your car. Get it up on axle stands and not ramps, you need to remove the drivers side wheel and undertray if fitted.
Open the bonnet and remove the little 10mm bolt that holds down your air con pipe, the big silver one coming out of the compressor and past the idler pully, top l/h side of engine as your facing it. This is to give you a bit of wiggle room once the compressor has been unbolted.
Under the car remove the 14mm nylock holding on the clutch plate. I couldn't quite get It off without using a bar to move the engine over to the passenger side ever so slightly. 3mm or so not a lot.
Then with a magnet or small flat screwdriver remove the shim/washer.
Then unbolt the x4 12mm bolts that hold the compressor to the block and pull it down ever so slightly. I used a ratchet spanner for the bolt at the top L/h side as I couldn't get a socket in there. All the rest you will get with a shallow socket.
Now you should be move the full unit up, down, left and right. Were not talking a lot as you dont want to put to much pressure on the aluminium pipework and risk damaging it.
Next you want to remove the pully. Its held on with a circlip. I tired with numerous circlip pliers and non were suitable so a trip to halfords got me one by laser. I cut 20mm off the length of the handles which give me enough room to access the circlip. Once you have the circlip off you unfortunately need to bolt the Compressor back to the block with x2 bolts. This is so you can pry and hit the pully without having the compressor move and damage the pipework.
I used x2 a pry bars at 9 and 3 o clock to rock the pully side to side. It only moved about 1mm but after 20 mins I had worked it loose without damaging the pully. Unbolt the compressor again to fully remove the pully otherwise it will hit the body work.
Then remove the wiring to the electro magnet along with the circlip and slide it off.
That's the easy part done
Put your new electro magnet and circlip onto your compressor and connect up the wiring.
Then put your pully on to blocks of wood not covering the hole where the bearing is coming out of and using a socket hammer out your old bearing thats in the pully. There are some little tabs holding it securely so its quite difficult to remove but a good couple of hits with a 4lb lump hammer works a treat.
Once out clean up the face of the pully with some Emery cloth lube up the bearing and press in your new bearing.
If you damaged the pully removing or its rusty from not being used now would be a good time so hit it with some sand paper to get a nice clean flat surface.
Pit your new pully back onto your compressor and fit the circlip (use the new ones that came in the kit for the 1.8 petrol).
You can now bolt the compressor clutch back upto the block.
Fit a new shim and clutch plate. Measure the gap with a feeler guage I went for 0.55 which I think is to the higher end of the tolerance. Remove shims/add more to get the gap right. (Theres a guide on how to do this bit)
Sorry that it was so long of a read. Hopefully be useful to some people.
