Power steering Pump Bracket Binding

[bughuntr]

I have a 1987 K5 Blazer with a 5.7 liter engine with air conditioning. There's three brackets that support the power steering pump. One at bottom of the block right of timing cover, one at top right bolted to exhaust manifold and the other is bolted to the pump. It seems that one or all of the brackets got bent, but not sure how. I did have the pump replaced at a shop 18 months ago by my mechanic I replaced the pump lines a few weeks before that because I thought they were leaking, but found that It was the pump seal which was replaced . At the time that I replaced the pump lines I had no problem adjusting the belt and it moved freely. I haven't been off-road since the repair, only city driving.


I acquired a power steering pump assembly, like mine, from a local wrecking yard without the two other brackets. I put it in place and have the same problem. With the lower and upper right adjustment connected the left pivot point is off to the left about 1/8th-3/16's". I noticed that the pump and crank pulleys don't seem to line-up. If I move the pivot bracket arm, left one, out about 1/4-3/8" it lines-up. I found a diagram online that shows that the non-A/C has a shim, but not sure about mine.


Any ideas would be appreciated. I have some pics.

Well no more problem!

Not sure which piece was the problem. I aquired all three parts from a fellow member and had the same problem. I was going to bend the upper part of the pump bracket, but decided to shim the upper/right exhaust manifold bracket. I had to swap the two manifold bolts which I determined someone installed incorrectly anyhow. This allowed me to move the bracket more to the right and now the bolts were even. This was easier that heating and beating the left pump bracket arm. Now all is good and moves freely.
