Power Steering pump.....

[Ballsy]

Ok ive searched thru the forum and seen that a saxo PS pump can be retro fitted, mines is sleaking and rather than goto the expense of changing it(engine out almost type job) im going to fit an electric one!! So ive got a few questions that havent been answered before.....

Any particular saxo/106 one?? eg is the 1.1 version different from the vtr/s??
Where has other folk got theres mounted?? pics would be very helpful
Did you make up a brakcet to sit it on? Or just somplace on the body?
Been said that the pipes are a direct fit to the pump itself?, do they need extended?

Was hoping to make up a "How To" guide with loadsa pix as i go for future reference!1


Cheers

Not done the job myself, but I gather that most people go for mounting the pump where the washer fluid reservoir normally sits.

B.T.W I think a how to guide would be really appreciated.

is yours a ajp ? if so its a landrover pump and is not that hard to fit its not a engine out if its sheared the pins it might be different but i did one in about 2 hours, a proper pump will allways work better than a electric pump as its got way more response,

Is that a fact, or your opinion? I hope you don't take that as it sounds. I'm just curious, as my Cerbs engine is out at the mo and I want to do something about the heavy and sluggish steering at low speeds. Its got the hydraulic system at the mo, and was hoping to keep it that way. But prepared to go the electric route.

I've got new upper & lower ball joints, new track rod ends, and will be renewing all the bushes once the wishbones,etc are painted. So hopefull that will go some way to sorting it out. But I assume the rack will need refurbishing, and also the PAS pump.

Good thread this. Looking forward to hear what peeps in the know say.

I have an electric pump in the LS Cerb. It's fine. If anything, its better than the original at low speed.

People fit the Saxo electric PAS pump if the 'woodruff' key shears, to save the time and expense of an 'almost' engine out job.
If your pump is working fine, and is just leaking, then you may as well just get your original pump replaced or repaired - not mega bucks.

[caduceus]

Where is the woodruff key? Anyone got a picture of it?

Thanks

sorry for hyjacking your thread OP

[brogenville]

A woodruff key is just a small piece of metal that connects an inner shaft with a flush fitting outer shaft. Its a bit like a 1p coin thats been cut into two half moons. The curved edge of the key sits in a curved groove in the inner shaft, whilst the straight edge slides into a notch in the outer shaft.

You will certainly have to remove the pump to change the wood ruff key.

Its worth noting that there were (at least) two different sizes of woodruff key used, so presumably if you have a later car (my engine was from a 99 car and it had the bigger key) you dont have to worry about the key shearing.

Cheers Rob.
Mine is a 99 too, so must be the same larger one. The pump will be coming off when I get round to working on the engine. So I'll have a look then.

You couldnae sneak out and take a wee picture of where its sitting?

Yeah the pump is just leaking, well so ive been told from the guy whos garage its in!! Just thought it would be less hassle fitting an electric one, no wanting to have it fixed then the woodruff key shear a week/month/few months later!!

[jonbarrett]

Just out interest if you bypass the original PAS pump with an electrical one how do you keep the original one lubricated to prevent the whole assembly siezing. If the key has sheared the shaft will be spinning in the bore which it is not designed to do.

[shpub]

First thing it is in.... dare I say it.... I think the Purity Police are occupied on another topic.... a Cerb with an LS1 instead of the AJP. There I've said it.

The pump is located where the washer bottle used to be i.e. close to the steering rack. I'm using the Kangoo version with a built in reservoir so the washer bottle is now where the PAS fluid reservoir used to be. I haven't got the front cover in place as it needs some mods. IIRC the saxo pump is also fitted at the front.

[julian64]

Nope the purity police are here too. .

Just kidding , although I have an engine out in my garage as we speak and if anyone wants to look at the PAS system they are welcome

Could grab a pic of mine tomorrow if you still need it.

The idea is that in manufacturer vehicles you fit Electic PAS to reduce load on the engine as you only actuate the pump when required. The problem with this comes where you have turn the pump on to turn (icrease the load).

Personally I find the delay it takes for the pressure to build when you turn the wheel is too long and it wrecks the "feel" of the steering. However, I only fitted it for ease of slow speed driving and when moving along fast you hardly notice the difference.

[shpub]

I've controlled mine via the ECU so that it is running when the engine is running. That means there is no delay at all and in practice the only real electrical load is when the steering is used.
