I was wanting to change the belts out since it was time on my 84 k5 blazer 6.2.
Well i was loosening the brackets and the power steering one broke. Just the tab piece that hangs over.

So my old man was helping me with it and he said why not just buy a new pump while we are at it.

So we bought the new pump from advanced auto, and rented a pulley puller kit.
He wanted to pull the pulley so i let him. A few minutes later i heard him swearing up a storm so i went over to see what happened. He had bent the original pulley fly wheel off the old pump so now i have to try and find one.

Since this is the 6.2 i was wondering to get a new bracket do i have to find a 6.2 specific one or can i get one that would fit the 350? I have searched everywhere and cannot find a bracket for the 6.2.
And now for the pulley fly wheel do i have to find a 6.2 specific one as well?

Thanks guy.
 
There's a part number on the pulley itself you can search for. Likely reproduced. The bracket can be rewelded or replaced.
Someone somewhere would likely part a truck out or Ebay cucv surplus.

Weld it back together. Not sure which tab broke, but here is how I fixed my 6.2 P/S pump bracket:

Super easy fix. If you don't weld, find your local fab shop and they should be able to help you out.
 
I got the bracket welded and put the new pump in and tighten all the bolts back and the belts get tight. However when i start the engine and try and bleed/use the power steering the belts become so lose they flop around especially the ac belt.
 
I always have a hard time getting the P/S belt on my 6.2 tight enough not to slip and squeal (especially when the plow is on the truck)--I needed 3 hands or two people,and had neither..it's dang near impossible to use a bar to tighten the belt and tighten the bolt on the slider without it slacking off again..
I ended up loosening all the bolts,then I put an adjustable wrench on the P/S bracket,the side facing the left fender ,sticking up,and used a ratchet strap anchored to the right side fender ,and tied to the wrench,to apply tension to the wrench and tighten the belt and hold it there while I tightened the bolts...

My alternator belt likes to "flap"on the slack side while its idling,no matter how tight I put it,so I just run it snugged up enough not to slip & squeal,rather than kill the bearings in the water pump and alternator --I guess its the nature of the diesel's firing impulses that make the belt do that..later ones had a rubber dampened harmonic balancer pulley to help eliminate that..
 
I am still working on the damn thing. I get the PS tight then the AC gets so sloppy and flaps around and i have to stop driving it.
 
No A/C on my pickup...only one belt runs the P/S pump too..in my estimation this negates any gains provided by hydroboost,when it is so easily lost should the belt fail,get wet or oily & slip--now you have no power brakes OR steering..wonderful situation in a 1 ton pickup?..
I don't think so...
I've had a hard time feeling confident driving it after having the pitman shaft seals fail in it suddenly..its scary to know two little seals the size of a half dollar,and a rubber belt, is all that is between you and being able to stop & steer the truck safely..beats me how there isn't more fatalities related to loss of hydroboost assist..

A properly working hydroboost system is no more dangerous than a vacuum system. Either way you get 3 or 4 full pumps of the pedal before you lose boost, if input power is lost.

Your accumulator is broken, but that is no more dangerous than if you had broken your vacuum booster's accumulator or any other part of your vacuum system.

A failed booster is equally dangerous regardless of what powers it.
 
Agreed--but at least you still have power steering if your vacuum booster craps out!..you can drive without one or the other with some extra care and difficulty,but not both ..

I've had the engine stall and lose vacuum to the brake booster in other vehicles and to me,it didn't feel as hard to stop them without vacuum assist as much as it does when a hydroboost loses pressure and has exhausted all the reserve out of the accumulator..

Losing the assist to the brakes is one thing,but no power assist to steer also,is twice as dangerous..it's a good thing I have pretty strong arms,I still went in the ditch a few times trying to take sharp corners at intersections,the steering effort was incredibly hard..nearly impossible from a dead stop too..if a weak person or small woman was driving it would have likely resulted in a crash..

I did a dead stick landing today in the truck. No power steering or brakes. And then I was on a tow strap for 15 miles or so. Didn't seem any worse than a gasser. It's the same steering box. No orphans were run over.
 
Well I think I finally got the belts on ok. However I broke the oring that seas the power steering pump and leaked all my brand new ps fluid put.
Anyone know the name or part number of the seal?
