I have a 1994 Chevy S-10 Blazer the pulley is toast the bearing is bad in trying to remove the bolt is loosened but now turns freelly i cant get it off the tensioner assembly,do i have to remove the hole unit and if so how, it is bolted to the same bracket that holds in a/c compressor and looks like i would have to remove it as well, hoping to not have to do that but if i must .......well you know.

Thank you for your time and hopefully quick response im doing it now...

HELL NEVERMIND!!!!!!!! Igot it ty ne ways ALL

Is it the adjustment teninisor or a solid idler pulley?
Is the bolt in the center of pulley?
If it turns and does not come lose you have stripped the threads.
