Cerbera V8 Power Steering Pump - How difficult to change?

[pmessling]

The hose attaches via jubille clips.
One is a return from the rack to reservoir, the other is reservoir to pump.

Hi it was a long time ago but check this link you can see what the hoses look like.

Thanks for getting back so quickly. I particularly fancy the braided pipes

BUT

What I really need to see is where the pipes attach to the Pump Housing.
I just can't make out where that happens as there are so many chassis supoort struts.

(Let alone how I'm gonna access them)

The Manual is, its usual, helpful self....

Peter, you are a bloody STAR !!

THAT was the photo I needed !!

I want to replace the two pipes that go from the Oil Reservoir to the Pump.

Hello,

You probably already know this but it's only one pipe from the reservoir to the pump?

I did my pipes last year, all three including the high pressure that runs from the pump to the rack.

It was a pleasant enough job, I accessed everything from above which I found to be the easiest way, as long as you have removed the front cover.

The biggest pig was my access panel in the wheel arch, seized old screws caused me some pain!

Paul, before you launch into what could be a world of issues, why do you want to change those 2 pipes?

This pic shows a few ports and I wondered if they are what I should be trying to access ?



Can you tell me where the Pipes attach and what fittings they are please ?

1 - PS Pump out
2 - Oil Pump Pressure Relief Valve
3 - Oil Pump out

Paul,
Thanks for that guide

So I'm presuming that it's the large diam. Pipe which exits the bottom of the Reservoir that delivers the red ATF Oil to the input of the PAS Pump. Then exits the Pump, under pressure, to the Rack. Then, in a small diam. pipe returns the ATF to the Reservoir in a constant flow system. All other Oils you mention in your Guide being Engine OIl, correct ?

Hi William,
I have had a few leaks from this system forever. The first I traced to the pipes where they attach at the Reservoir
BUT
Since fixing that, the amount of Hydraulic Oil on the underside of the engine has increased and I can go though a reservoir in no-time at all, nowadays.
Even if the car isn't running.
So I just presumed that the hoses/clips were shagged at the Pump end and, having anbsolutely no access to it I can imagine that is an unservced area.

Any thoughts on this situation yourself ?

Ta !

Ooh, Duncan, you've made an incorrect supposition there, if you think I have any clue as to what I'm doing

So a big Thank You for your comments

However, your last throwaway line "my access panel in the wheel arch" was The Shocker as I haven't discovered this yet !
(I am assuming that you don't mean either the panel behind the headlight cluster or the rear one, covering the Air Con unit )

Thanks for steering me in another direction (Pun apologies) coz I Just CAN'T BELIEVE that anyone would assemble a car as badly as what I am looking at

The hoses from the reservoir go down and under the drivers headlight. They then loop back and come out through the grommets you can see behind the radiator. You need to remove the panel in the wheel well to feed the new hoses through.

[Mr Cerbera]

Hi Gordon,

Thyanks very much for that.
I have, in fact, ripped out everything from the front; Rad, Air Con and traced the pipes back to where they disappear under the Exhaust Manifold.

That's My Problem !!

Hello,

Please trust me when I say that everything is easier from above the car. As long as you have airbox and front F1 panel off, the hoses are easy enough to locate and follow.

I was able to disconnect and connect all hoses from above, apart from connecting to the reservoir, which is just sitting at the front of the car.

If you have a serious leak it will most likely be the pressure hose from pump > rack. I removed all 3 hoses and took them to Pirtek, they made new ones up whilst I waited.

Good luck, and please try from above, you can see it all so clearly

Hi Duncan (and everyone else who's been listening and laughing )
I have made this little Vid to show how impossible it is to access the PAS Pump pipes frm the Top of the Engione Bay.
Once you've finished laughing, perhaps you could indicate what I'm doing wrong .
All the Best,

PJ

Bless you video says private at the moment.

Your posts have helped me out lots in the past, so if I can help then I'm only repaying the favour

OK, without knowing exactly where its leaking from you really are stabbing in the dark with a fix. It could be connections at the pump or the rack. I highly suggesting using aerosol cans of brake cleaner to clean everything off then re-checking for leaks after. Get the car on axle stands and check and clean underneath as well as the connections on the rack pinion housing under the F1 panel. You may or may not need to take off the front undertray to help you see what's going on.

Anyway to change the pipes going to the pumps it's best accessed from underneath the car. The feed pipe is held on with a jubilee clamp and you need a 7/8ths spanner to undo the banjo bolt securing the pressure line from pump to rack.

Oh I'm surprised you say this, as I have been saying the opposite. If I can get away with not lying under my car I will, and access to the pump is easy enough from above. You also easily access the rack from above, standing the passenger side of the car and leaning in.

Regarding the leaks, I would replace all 3 hoses, as it's then a job completed for the PS maintenance. It's most likely the high pressure one though (was for me).

Hi Will,

Thanks for your comments and, yes, you're right. The immediate answer is not calling to me.
I have looked at the prob for some time and, after checking the various possible places of leak, they have consistently appeared at the bottom of the engine. I have had the 'front undertray' (Is there another ?)
off and, yet again, even with the motor not running, there is evidence of an ATF in the vicinity of the PAS Pump so I am quite convinced. That is apart from the fist leak appearing at he deteriorating pipe ends under the jubilee clips at the Reservoir end.
She's done 100K, way past her programmed life expectancy
BUT
I just don't want to give up on her.

Many thanks fo quoting the 7/8ths - That's gonna save me a lot of pain

To All,

I have changed the access priviledges (Dullo !) so, hppefully, you can all have a laugh at my appallingly made Vid.
It's at times like these when you realise how important it is, when movies are made, to have a Light Man, a Camera Man, a Gaffer and a Runner.

Perhaps having a ramp has spoiled me ( single garage with Cerb and Tuscan means 4 poster ramp for storage). When lifting the car isn't a pain in the arse not having to manoeuvre around the exhaust manifolds is helpful, depending on the original orientation of the feed pipe jubilee clamp of course.

If you've removed what I call the front undertray (as distinct from the chassis brace around the exhausts) and the leak is dripping on to that somehow then spreading itself around/backwards through airflow then it kinda has to be the pump connections as far as I can see. With the pictures on this thread of the PAS pump and how it's bolted onto the back of the pump assembly it shouldn't be difficult to locate and undo the pipes.

Ahh that makes sense, oh to have a ramp - one day

Dear Mr Cerbera,

From above just means top of the car rather than laying down, I was definitely able to get my hand to the bolt head (pressure pipe), with a socket, then wiggle a ratchet onto the socket. You don't so much have to see the connection as feel it, head torch helped establish exactly where, then lean in with your hand.

Underneath the car annoyed me for some reason, so I was quite pleased not to have to persevere. When replacing the new pressure hose, I did have to pack out the socket.

I'll try and take some pics today, but I'm not removing the airbox so we'll see

[Mr Cerbera]

Vid should be fixed now

Oooh I do love a man with a good sense of humour.

The pics on this thread show the engine out of the Chassis. and that's my problem.
The PAS Pump is shrouded in exhaust manifold and cylinder head water pipe from above, chassis braces and footwell bodywork from the sides and chassis main rail from the bottom.

I'll take another Vid from the bottom to show you my specific probs.

Oooeerrrrr, 4-poster ramp envy
Many thanks to both you and Duncan for your time though

Yes I enjoyed it!

You have room to get your hand to the bolt head and jubilee, which means a socket will go on too .

I'm not going mad, I was terribly pleased that I could get to the connections from up top

Edit to add:

With airboxes on, I reckon I could still get to these fittings?
