Power Steering Mystery


Recommended Posts

i test drove the truck after i replaced the tranny gasket and filter 

and now the power steering won't work 

it was working fine yesterday and today i have to pull the wheel real hard to turn the tuck 

I'm wondering what could have happend 

i checked to see if the fluid had leaked out and i didn't see any leaks 

sure hope i figure it out cause this truck is really starting to kick my butt  :fs2:

power steering is a stand alone mechanical setup run of the serp belt, no way a tranny service could affect that...

 

The OP has an '86, with a 3.4L V6 that was converted from a 2.8L. It may not have a serpentine belt. Certainly, a trans pan service wouldn't affect the power steering, but the weather is getting colder and drier. If the belt tension was marginal before, colder weather might result in enough slippage that it won't power the pump.

 

I can't think of anything else, so that's my story and I'm stickin' to it.

yep the belt slipped off 

its because in order to use the new 3.4 motor and keep the one surp belt system

instead of the original 2.8 three belt system 

i had to swap the compressor and the alternator (because the compressor is to long and hits the motor mounts)

so when i modified the bolt in brackets it was difficult and hard to get it perfectly straight

and in line with the belt

You don't have nearly enough belt contact on the alternator pulley. Are you sure you have it routed correctly?

the battery i have in there is just a test battery i still have to buy a real one for the truck 

 

and the belt looks loose because i took a pic of it when it was loose 

when i put it back on it goes on real tight it just slips off because its not properly centered 

the alternator and compressor need to be realigned i will work on that tomorrow

and when I'm done i can post a pic for you guys to see how i got it to work

What they are talking about on the alternator is the amount of belt contact or wrap on the pulley, not the belt tension. The wrap on the compressor pulley looks a little marginal also, but better than the alternator.

 

Edit - corrected spelling. Getting tired of Apple putting in words it thinks I want to use.

After another look, that upper radiator hose bothers me, too. Is there a decent amount of clearance between the hose and the serpentine belt? In the photo it looks like they could be making contact. If that's the case, it wouldn't take long for the belt to saw through the hose.

the clearance from the belt and my radiator hose is fine 

i just had to use a flex hose because the original hose from a 2.8 on the top would not work on my 3.4

and i got my alternator shimed up so that it and the compressor would pull the serpentine belt straight

but as i got done doing that i notice that the belt tensioner pully was falling off of alignment

i thought it just needed to be tightened but evrytime i did that it would just un-tighten itself

so i just removed this one part that was like a washer around the bolt and replaced it with a regular washer

tightened the bolt down and now it all spins straight and tight no problem

ok so after i did all that and everything was running smooth in park on idle 

i decided to take it out for a test drive when the vehicle is in park and running it sounds great 

but when you put it in drive 

it makes a da da da da da da da da sound 

and the sound is in proportion with the gas when i accelerate it 

I'm not sure if its the engine but its sounds like it could be coming from the tranny or the torch converter

 

i have started a new post and uploaded a video link so you guy can go check it out
