Help with p/s pump bracket 87 Firebird

I noticed the other day a vibration in my engine. At the same time I noticed a belt squeal in the mornings. It would go away and not come back until the next morning. I checked the belts and pulleys and found the p/s pump pulley bracket has a crack in it starting next to a little notch on the left side of the bracket and a slotted area. If I pull on the belt I can see it move a little. How do I get the bracket and pump off? What do you pry against to tighten the belt when putting it back on? Do I tighten the A/C belt that also goes around this pulley or the p/s belt first? Thanks.

Tighten the PS belt first.

There are bolts & nuts on both the front and back of the pump. A bit of a pain, but works when properly tightened.

Re: Help with p/s pump bracket 87 Firebird

To get the bracket off, you may need to remove the pulley from the front of the pump. You would have to tighten the P/S pulley first, then the A/C compressor. The P/S has 2 belts and the A/C compressor has 1. Don't want to mess with removing the pulley, I have a P/S pump with brackets sitting here. Willing to sell for $15 + Shipping. Worked fine when pulled. I switched to serpentine belt system and my brackets came with pump already attached. PM me if interested.
