the belt was still turning but the pulley was going really slow got one from ebay went to fit it and it was the wrong one lol but when i looked at the old one properly and took the pulley of it i noticed that the bearing in the middle had half of the balls missing on the top part and all the casing was broken i dont think you can get the bearing out on its own so i was wondering if you can just buy the pulley with the bearing on its own hopefully thats all it is . the air con as never really worked properly as ive had it gassed once and some dye put in it for leaks but never had got around to taking it back but iknow it must have all leaked out again because it wasnt working lol and when i un done the pipes today nothing came out thanks for your help
