xantia clutch slave cylinder

[CitroJim]

Everything crossed doing clutch master/slave cylinder and have sourced a pipe for the hydraulic system.
Really need to get this car done now.

All the very best with this.. My fingers are crossed too...

Well all the hydraulics working fine now.

However managed to destroy another slave cylinder but may have figured out why.
On installing the slave cylinder have not realised we needed a specialist citroen tool to yank back the clutch release fork to properly engage the clutch release bearing. luckily i have one more slave cylinder to do your trick Jim and set up a bleed on it.

Does anybody know where i can get this specialist tool from or does anybody have one that i could please borrow.

Thanks Mark

I made my own Mark from a piece of 6mm steel rod bent into a crook at the end and attached to a wooden handle...

I also have an example of the official tool but I find my ersatz tool works much better...

This is the pukka tool:



This is mine...



Ten minutes work to make one...

Hook it into the hole in the arm below the cup and pull smartly to engage the bearing...

The hole you can see in this picture:

Thanks Jim will try that and then make up the bleed on the slave you have kindly supplied me.

Fingers (and everything else) crossed it all works this time Mark

I hope so.This is starting to really get to me now. Never known such stress from a car.

Ever had a Series 1 XM?

[holmedog]

No and by the sounds of it i don't want to Jim.
I thought i was doing the right thing by saving this bloody thing. Now i thinking it didn't want to be saved. Will keep on persevering and hopefully it will all come good.

It will all come good Mark, it will and then it'll settle down into an excellent and reliable car... been there a few times myself now...

We have a 1994 in the shop right now with a leaky clutch that has pretty much quit working. We’ve not had any luck searching for a hydraulic pack for this car. Does anyone have advice where we may get the clutch cylinders, either as a complete assembly with the hoses, or as components? Does anyone repair these plastic components?

Have a look here, there are some parts for older cars that are available here that are no longer available directly from the manufacturer:

Which engine does it have? I didn't think that hydraulic clutches arrived until a couple of years later.

I think that you will have to find a used part, as new ones have been unobtainable for years. A Peugeot 406 with a 2.1TD or 3.0 V6 is a suitable donor.

@Xantia_v6, this car may be a bit newer than 1994. However, others have told me these cars had cable operated clutches by the late 90s and this one is definitely hydraulic. Sometimes model years are “adjusted” to allow import into the USA. This car came to us with an American license tag after being imported this spring. The slave cylinder came out of the transmission bell housing without difficulty. We can see where the fluid was lost over time. The cylinder is plastic, so does not look like a good candidate for rebuild.

The cylinder is hooked to a plastic hose which is threaded under a motor mount into the area under the main hydraulic reservoir and brake cylinder. It appears all that will have to be removed to access the master cylinder.

The idea of going to all that trouble to install another 25-year-old clutch hydraulic package does not seem very appearing to me. Is it true that there is no factory-supported service solution for this? Were these cars just scrapped when jobs like this came due?

I don’t see any reason we could not fabricate mounts for a pair of conventional clutch cylinders, but that job will be a great deal of time and money and I don’t think this is a high value car.

While a appreciate the suggestion that we look for used Peugeot parts, those are equally hard to find in the USA, and for us, as a professional shop, fitting a used part in a process that may represent several days of labor seems like a setup for disaster when it too subsequently fails.

The car in our shop says Xantia on the rear body, and Activa on the engine

There were two types (three, but the third one is sealed type for RHD) of hydraulic clutch assemblies: sealed and non sealed system.

Sealed

Non sealed with fill up tank

@RobisonService from what you write, I'm not sure which one is there, if not something very different.
The non sealed system looks to have some advantages, like it can be disassembled and has bleeding valve.
I have that one on my xantia but I would be glad to swap it for a cable, if that would be just as easy as it sounds.. If you have some widely used type of cylinders there, I would go the way of making some brackets or adapters for them, if necessary. Where is the leak, inside the slave cylinder or some pipe connector?
I think both kinds of these were available new here in Czech republic, two years ago, at least the slave for non sealed system I remember for sure priced alone over $140..

I got another troubles with the clutch recently:
I switched clutch bearing two years ago and don't remember if I just plug the hose into the slave cylinder afterwards when the job was done and pumped with the pedal, but I know I got the clutch working easily. For the last few days it was harder to shift first two gears and reverse, until it got almost impossible to shift when the engine was running and was cold. I noticed the fluid in fillup tank got down from max to min level and the clutch pedal was low on the ground. I was able to shift only when pushing hard to the floor, yesterday I removed the battery tray and air filter and tried to bleed the slave but I can't find the right way.
When I first tried to open the bleed valve on the slave when the clutch was pushed, the clutch pedal fell to the floor and that was it, only very little oil got out with bubbles first time and nothing afterwards. I just opened for a half sec when the pedal was pushed down or tried the it was moving down. Nothing. I have to search better for the bleeding procedure, sad that haynes says no information available in the time of writing.

I had to remove the slave cylinder from the car, push the rod in and pour the oil into the connector hole when slowly releasing the rod, only that way I got it full of oil with no air. And I dipped the connecting pipe into bowl with oil and pumped the clutch until no air was coming out. I don't get how it works now, have to understand it better. When I pump the pedal, the level in the tank goes up and down with the pedal, and so dows the slave cylinder end of the pipe - pushes and sucks the oil on down-up motion of the pedal. I got it working and correctly assembled on third try (the metal clip holding the pipe in the slave cylinder is not engaging itself well, I had to help it click better, or the hose just popped off when I pushed the pedal). Not a good way of bleeding, definitely some air got in at least because I have to push the slave slightly when it's engaging with the gearbox body, and on release it will suck a bit of air when it's not connected..

Afterall, the clutch disengages at least better and I'm able to shift all gears easily, but still the pedal seems too low, it's about an inch under the brake pedal but I never had it higher, I think. I have to give it another try of bleeding
