Assuming you have a york compressor. The idle tension pully has a bolt in the back of the assembly. The bolt goes towards the front. This bolt holds the assembly to the mount bracket. Loosen this bolt and the unit should pivot.
Bolt number 25 in the picture.

To tighten the idle pully, place a wrench on the cast metal L shaped assembly that the pully is mounted on and rotate the setup. While holding the tension, tighten bolt #25,
