Brief Encounter II - The Sequel

[CitroJim]

It does need a serious degree of cosmetic attention The whole car is covered in small scuffs and scratches but all things considered it looks pretty good really The front of the bonnet is a bit chipped.

It needed bumper corners painting and a machine polish IIRC

Yes, that will certainly resolve a lot of the issue Gareth, plus the wheels badly need a refurb...

In exchange for an Activa clutch job?

Done Plus a Lexia session and check the pressure of a couple of spheres

Let me know when, weekends quickly get taken over (as do yours) with SWMBO and HWMBO.

[CitroJim]

Done

And dusted Gareth I'll be in touch!

My V6 continues good although I had to do the Hydractive diode mod today as the replacement rear electrovale I fitted had an intermittent diode and was not always switching reliably into soft mode.

I must say the hydractive ride is sublime, as is the engine and as is the gearbox now it has learned how I like to drive. I reckon it has a "doddery old git" map in there somewhere, especially for me

Just one issue: When restarting from half-hot , the idle is a bit erratic for a few moments but it soon clears. Seems worse when the car has been stopped for about 30 minutes after a good run and the outside temperature is scorching (as it is today here). is this normal for a V6.

Otherwise, she runs like a dream...

I still look for a non-existent clutch pedal at times and go to change down as I come up to a junction I'll be that when I get back into one of my others I'll forget to use the clutch and/or change gear

Just as a footnote... It is apparently possible to remove the 4HP20 from a 406 without removing the engine!. Maybe also works for a Xantia?

[jgra1]

I looked through once before and I reckon its easier from the top with the engine, especially if you dont have a 2 post....

I had to take my engine out for other reasons, but I still think I would have done the same route if just gearbox..

John, I agree totally. You and I know that the job of getting the engine out of a V6 is not too bad given its "cassette" nature.

Even if it were possible to remove just the 'box, which it is not in a V6 Xantia, it would be fraught with great risk of inflicting expensive damage. For instance, the TDC sensor is inaccessible and you'll break it if you try to remove the 'box without removing the sensor first.

Which leads onto a terrible thought. If the TDC sensor packs up, it's an engine out job to change it EEK!

Hi Jim
now ive started to strip down my 4HP18 properly on cxm i thought i would come back to this thread for a quick comparison of the two boxes and it seems my first thought that the 20 is just a computer controlled HP18 couldnt be more wrong, the boxes are completely different and in fact i would say the 18 is far simpler in construction than the 20, did i read right that the 20 has 2 Planetary gear sets too??

[CitroJim]

Hi Dean,

Good stuff

Have you been taking any good pictures of the 4HP18 coming to bits? It'll be interesting to see the differences

Yes, the 4HP20 has a Simpson gearset where the annulus of one is coupled to the planetary gearset of the other. I believe the 4HP18 will have similar as you need two gearsets for the 4 speeds + reverse and Mr. Simpson enables this in a compact set of gears.

[Deanxm]

Hi Jim

Well the casing is nearly empty and there is only one gearset the thread is on cxm in the drivetrain section if you would like to cast you expert eye over it.

[CitroJim]

Thanks Dean,

yes, I will

Where is this cxm thread?, please post a link for us unenlightened ones.

Just read your stuff on v6 really clear pics. I have to to remove inlet camshaft, in car to change tappet. However, when i removed covers, Iwas confronted with the vairable valve timing devices, on the inlet camshaft. I didnt want to go any further, so I screwed it back to-gether. Does anyone know if I can go ahead and just remove the sprocket, in the normal way, as in the picks, is there somthing Iam missing? Thanks, Dave.

Dave,

Is yours the later V6, as fitted to the C5? If so, it might be quite different.
