Power steering pump.... should I get a Gm

[mjbrox]

I was having all sorts of steering issues so I replaced the pump, box and shaft from a parts truck I had. It was doing great so I did some off roading and the ps totally went out. Steering is still tight just no power.

Did I just have some bad luck?

I'm thinking about getting a gm pump

 

[ezzzzzzz]

Assuming it is a D1 the gm pump will work, not so on a D2.

Okay I just started it and now the power steering is working

Make sure the system is bled completely. Air bubbles will cause intermittent problems....

You have to bleed the air from the box - otherwise it'll foam up at the first convenient occasion.

If your previous box broke in a way that metal bits found their way down into the system, you need to use an inline filter on any of the low-pressure lines. I didn't four years ago, and it resulted in the next ps pump only lasting me 400 miles.
You may want to use this filter regardless of that.

GM pump on the D1/RRC is a fantastic upgrade. The cost of the kit is about five Ben Franklins, but ... after you install it, you forget about leaky hoses and dying pump and whatnot. It just works.

Are you talking a ham can pump or an S10 pump? I never had great luck with the S10 pump.

I have used both the S10 pump and the canned ham Saginaw pump. The S10 pump was noisier and other than being less expensive was not an upgrade.
The Saginaw pump from an 87-91 V8 2wd GM truck is a vast improvement and will use the stock hoses. 14mm x 1.5 o-ring fitting on the hi-pressure side of the pump.
I no longer have my Disco, but i took the homemade bracket off it to re-use.

This pump and bracket is from a 79 Monte Carlo, truck pump the filler is rotated about 30 degrees clockwise,

The original plate mount I made was too flexible, I removed the lifting loop and doubled the thickness of the mount to stop it from twisting when it revved up.

The old box definitely failed in way that took out the pump. I did not really do any special need procedure. It was not foaming when when I looked at it. Could extreme changes in elevation affect this?

I guess the next step is to properly bleed it

Is it possible to use a shorter pitman arm since the stops are generally restricted with large tires?

No clue, not sure the benefit but I would think that would screw with some angles. I only run a 2" lift

Extremely unlikely.

Shorter Pitman arm - that would be one bitch of a part to find.

 

[mjbrox]

Okay, I am going to try and salvage what I have one for a number of reasons. Most of which, my wife is getting tired of me spending money and time on the Rover.

What is the Bleed Procedure? That seems like a good start

Something to that tune -
- fire up the engine, have somebody crank the steering wheel all the way to one stop.
- crack the bleeder screw on top of the steering box, bleed it 'till you don't see bubbles.
- repeat with the steering wheel to full lock in the other direction.

I did it a few times. I could never feel if it made much of a difference, maybe except for the case when I had the system full of pink foam.
