retracting P.S.Idler pully

[Robert E Cooley]

Following the Power Steering Pump Repair "How To" but the Idler Pully does not retract when I turned "clockwise" on the bolt. The bolt retracted 3/4 inch but the pully did not retract or take tension off the belt. Now what ?
Cut the belt and hope to replace it when I free the pulley ? or remove the entire idler Pully Bracket [ugly]?Other options,Thanks,Bob
