Any idea on cost.....

[Disco-Ron]

Of a new, genuine land rover ie, from land rover steering pump for a 200tdi Disco...????

I'm having no joy with seemingly non genuine ones.... they're all crap....

[DREWSTER100]

yep if you want a genuin part sit down over 700 but you can get them for less than 200

[DREWSTER100]

i used gec 4x4 for a new one and that cost 180 01527525253

[Disco-Ron]

700.. you're having a laugh..... oh well, non genuine it is then i guess... they just seem to be rubbish, the last new one has lasted 6 weeks beofre i started leakin...... being replaced under warranty... still not a good sign though.....

Thanks!

Try going direct to the OE manufacturer  Adwest  Engineering, they are really helpful and  supply new or factory recon units.

Adwest do the boxes.... not pumps from what i can see on their website.... thats where my current box came from.....

There's something amiss is they are going that quickly :shock:

yeh, but what.... they're bolted up square, belt not too tight, correct fluid.... i make sure not to hold it on full lock..... got new box, and new flexi on the pipes.... what else is there???  ever since i fitted the pump, it seemed to groan a little.....

i just don;t know what it can be......

One thing i did wonder, was wether the fluid may be getting to hot..... i thought about fitting a cooler....

[Range Rover Blues]

Groaning, I was going to ask but I couldn't think of the right word.

The PAS system has a radiator, the exposed steel pipework at the front of the engine.  On some cars you see a loop under the radiator but I'm not sure LR put one on.  I don't think it would hurt if you added a loop of pipe though.

Thing is if it's getting too hot (and that would cause it to pack up as the oil is too thin) then something is wrong and the groaning might be a clue.

I don't know if you are aware but the way PAS pumps are built they have inbuilt pressure relief, often the sides of the pump body are spring loaded, so if the system goes over pressure then the pump body parts.

Well mine only groans if i'm dry0steering or holding it at full lock, as it should.

if yours is groaning all the time then the system pressure is too high.  You could try getting the pressure checked but I'm suspecting that the PAS box might be faulty.

[Disco-Ron]

The box can't be faulty, it's a brand new adwest box....
The pump that i've just taken off, was fitted at the same time as the new box, and new flexi pipes....
The previous pump seemed to groan a little, but then the box that that was fitted with failed..... this damn steering has cost me a fortune, and i'm at the point now of seriously considering selling the truck as a result, it's doing my flippin head in.... and i don't have endless cash to sort it.....

[Les Henson]

Are you absolutely sure it's the pump? A dry TRE/drop arm joint or steering damper will groan as it moves. Raise the front wheels off the ground, remove the PAS belt and then turn the steering lock-to-lock and see if it still does it.

I wish I was that confident.  It should be mint but given the problems you arre having I wouldn't put money on it.

You've had the pipes replaced.  If oil goes through them and doesn't leak then they work, end of.

But the pump and box, you replaced them together and now the pump has failed.  Was the pump new?  is it under guarantee?

Given the expense I'd say fit a good S/H pump.  Ignore any slight leaks just to see if it lasts any length of time.  If it doesn't then it's the box.

OR, fit a S/H box for now, again a known good one, and see how it goes.

Because of how the steering box works it wouold be possible for a very slight mistake in the machining of the valve to be causing the fluid to overheat.  Does the power assistance seem about right, or too little/too much? more to one side than the other?

[Disco-Ron]

If i have the front wheels off the deck, i can turn the wheels from lock to lock by twisting each wheel quite easily, so nothing tight in the system....

The pump is being replaced by the supplier, i'll have it in acouple of days, and then i'll try again......

This will then be the fourth pump, and fourth box..... the in-between boxes were all recon..... which i gave up with.... one blew the bottom seal clean out, circlip n all..... then the next one the input shaft seal went....

i'll see if the new pump works ok...... i might even remove the damper, i have solid steering bars, and people reckon you don;t need a damper sometimes .... is that right????  the more i can reomve, the less there is to go wrong....  ever seen a disco without power steering..LOL!!!

Thanks for the ides guys.... any help is good help!!

[trecfive]

Have you checked that the swivel pin preloads are not too tight, big tyres a little soft, all add up to more resistance.

[Disco-Ron]

everything is nice and free... and i'm only using 235's at the moment.... with 35psi in them....

[Range Rover Blues]

It's going to be something obvious ](*,)  But I can't think what.

Let me squeeze my brain for a few hours.

[Ja1983]

i`m guessing you`ve changed the belt..?
maybe a blob in the belt throwing a vibration into the pump..?

i dont think i`ve seen one that doesnt leek in all honesty

[Range Rover Blues]

Some of the symptoms you're describing, the groaning from the pump and the seals blowing from the steering box make me think that the whole system is running at too high a pressure.  The short life of many of the components backs that up.

A silly thought occured, but I'll share anyway.  One thing you havn't changed is the reservoir.  It has a filter/screen in it.  Could this be blocked? have you changed it at all.  It might be worth checking that the oil return from the PAS box has no restriction in it at all, it should run very freely.  Mine does generate a slight surface froth in the reservoir BTW.
