lets see. 95 GMC vandura 3500 w/ 454 engine. problem: i think my air conditioner compressor pulley bearing is going bad. its making a fairly loud metallic whirring noise with the engine running and feels like its not lubricated when i spin it by hand altho it spins freely. i saw a exploded view of a compressor unit that had a nut holding the clutch hub on. mine doesnt have a nut, but i do see a "key" in there. i have a few questions i'd really appreciate the answers to: (1) can i pull the hub off with a gear puller? is that how its designed, just pressed on or should there be a nut there and its missing?
(2) are there any internet sites where i might find an exploded view of my air conditioning compressor?
(3) i'm not averse to just pulling the entire compressor assembly out and replacing it with a "dummy" pulley. sorry, i dont know the proper name. i assume such an item is available. is a dummy pulley a standard item i can find at autoparts stores? i dont think i'm ready to try to replace the compressor at this time. i need to be on the road soon and will have more time later.
btw, i'm rather surprised "they" design a car that cant opperate just because an air conditioning part broke.
i hope i get some replies. thanks. (and i apologize for the fake name). john
