Hello Everyone

Just recently replaced power steering pump part# ETC9077 and added new Dexron III ATF fluid.
I lifted the front axle and added more fluid as i turned wheels left & right.
wheel turns smooth & small grinding noise from end from end.
turn wheel 25 times.
watch some air escape the system
no complains so far.

When I drop the front axle, tires make full contact
I try to move the steering wheel and its hard to move and pumps makes loud noise.
also noticed the pump stops spinning if move the steering wheel.

Did I missed a procedure ?
why is the pump stop rotating when I move steering wheel ?

*Belt is tight .
*currently has new gates V-belt notched.
*no leaks

also almost forgot to mention;
Several weeks ago I drove the truck with out any power steering
drove the truck home for 50+ miles.
I had no other choice, and Tow truck bill could have been thousands of dollars .

The problem I'm having could be because of it?

Thank you guy's for your time
and I'm really looking forward to hear from you guy's soon.

 

My first guess would be a bad pump. Was it a rebuild or new? If it's moving freely from lock to lock, while wheels are off the ground, smoothly and without resistance...then l'd start with another pump. When you originally had the power steering loss, was it on account of the pump or fluid leak? Can't imagine causing any damage from driving it with no pump assist, and again, if it's moving freely side to side...then l'd assume the gear/steering box is okay.

 

With the engine off see if you can turn the wheels it will be extremely heavy but you should be able to do it. The steering boxes on these are generally bullet proof and will function with fluid pouring from every seal lol

 

Honestly I don't think I fried my new pump yet because i didn't forced the pump at all
as soon as I heard and felt the steering wheel, I stopped quickly.

Question:
Does having a V-belt notched will create that problem?
Maybe that belt is not grabbing the pulley as it should.

 

Was the pump new or a rebuilt? Not saying you ruined the pump, it may have been bad out of the box.

If the belt tensioner or tension setting is correct, there should be no reason the pump isn't turning...unless pump is bad.

Also, what year, engine are we talking about? Hard to picture what's wrong, without proper information.

 

My 85 rover has 2.5 NA diesel
The Pump was purchase brand new and the tension of the belt is good.

don't you guy's think perhaps the Steering gearbox may still have Air trapped inside
causing this to happen?

 

Thank you, missed the 85 part in topic title.

No.

Usually, the air will work out of the system relatively easily...by moving the steering wheel from lock to lock (right to left) while running and with axle lifted. And air in the system would not prevent the pump from turning under load (axle on the ground).

Couple checks, lift front end, turn steering wheel from lock to lock, with engine off...do you feel any resistance? If not...then swivel ball bearings and pin, and other steering components are probably okay. If you can't turn steering wheel easily, you may have issues with one or more of these components. But...even if...you had issues with any of these components...the pump should not quit turning under applied pressure...unless they were frozen solid. But if that was the case...you'd feel resistance turning the steering wheel with engine off. Normally, if the pump feels added resistance from steering components, the belt will squeal some..as it tries to overcome added resistance...not totally give up.

To me...from what you've describe...it sounds like a bad pump.

Good luck.

 

Thank you Sir
I just realized one thing i was doing wrong by what you just mention above..
Tomorrow as soon as I get home and let the Sun go down & cool off
I will check & advise you guy's on my finding..
