Xantia hydraulic pipe

Post by **Duracell** » 16 Feb 2010, 17:14

Can anybody tell me how to tell the difference between a 6+2 hydraulic pump and a '6 sucker' pump?- I'm trying to help my brother find the correct part number for the front offside suspension sphere supply pipe on his 94 1.9D - the part no. given on 'service citroen' from the vin no is 5270EC, and this is the same as the part no that his local Citroen main dealer found for the car. When they supplied it it was wrong, and they say they can be of no further help with the information that they have. The pipe seems to change with the different pumps hence the need to identify the pump

Thanks

Richard

i may be wrong but i thought there is only two diferent pipes for a feed to a front strut,, appart fron N/S and O/S,

the only diference i would think is hydractive oe not,

non H/A has 3.5mm pipe and H/A has 6 or 6.5 with sections of large diamiter high presure rubber hose factory criped on,

i would think a 94 1.9D will be 3.5,

why do you think the wrong pipe has been supplied,

regards malcolm

ps.
this is great fun to fit especialy if you fit it back the same as the original, as it is the very back pipe across the bulkhead, from one side of the car to the other,

Hi Richard,

this should be straightforward to work out so long as the exact model type
is known; the sphere supply pipe can only be LX/SX 3.5 mm feed or the
visibly much larger 8 mm of the VSX model if it is a TurboD version. The
very fact it's split almost certainly points to a 3.5mm though. A decent Cit
Indy/Specialist will be able to make a new run of pipe for you for a
sensible cost.

The hydraulic pump of early models only has one metal thick diameter
high pressure feed off it's body whereas the later cars have 2 feeds and
a flow distributor valve on the front of the gearbox is dispensed with.

i have just looked on service citroen and there are two diferent 3.5mm pipes listed for the O/S, one is for a non sinker 6+2 pump length 2437mm 5270.EC,

the other is for a sinker 6 sucker pump length 2440mm, part No. 5270.EE

so either pipe will of these pipe will almost certainly fit as they are only 3mm diferent in length,

Only Citroen could manage to make something unnecessarily complicated
though I wonder if the Peugeot bean counters ordered the 3mm shortening
of the pipe to save a few cents.

So is there more of a problem with the pipe bought from the Prats
counter then as the minor discrepancy wouldn't be apparent?

The reason for the difference in length is the simple positioning and outlet between the anti sink valve, and the ordinary K valve, I thick the anti sink outlet is facing the FRONT of the car were as the sinker K valve faces the passenger inner wing, both obviously under the LHM tank..

A Sinker will only have ONE Metal outlet pipe comming from the pump, were as a 6+2 has two metal pipes... of course, plus the rubber feed pipe..

Thanks for the replies - I'm not sure about the lenght of the one supplied (although I have not seen it) but apparently it would have needed significant re- modeling to get it to fit - I'll get my brother to have a look at the number of outlets on the pump to identify which pump it is, although I'm almost certain the car is not a sinker - but that wouldn't explain the wrong pipe!!!!

Sort of, although off topic ZX vs 306 wishbone bush's (the rear of the front if that makes sense) , Peugeot do not sell these separately (or they never used to) Citroen did for the ZX. Apparently they are slightly different

In what way was the supplied pipe the wrong one ?

Early vintage cars had the pipe coming down from the strut top along the inner wing, where they were clamped, and soon cracked because the free length was too short.
All replacements went from the top towards the outer wing first, then back down along the inner wing.
All nearside pipes are like that, and it greatly increases the free length.
Probably that they give the offside design to the apprentices.

We’ve got old topics about that, and here's the only one I can find this far:

if you were supplied this pipe 5270EC it is 2437mm and for a non sinker,

i would think as you have to straighten the pipe out to fit it, i cant see a problem which ever pipe/system you have, as you only have to find 3mm,

but im sure your car is a non sinker so you will have been supplied the correct pipe
