How to change the clutch fork pivot (M5P gearbox)

Hi, I'd like to renew the pivot point)of the clutch fork on my S40 2.0 with the M5P gearbox (Renault) because the fork seems a bit loose on the pivot. The pivot is a small green plastic ball that is plugged in the gearbox housing near the opening where the clutch fork sits and is connected to the slave cylinder. I can't see any screw there so I assume the pivot is pressed in the gearbox housing???? Is it possible to renew it? Any part nr for that (I can't find any in my VADIS 2003). I've heard this is something important to renew when doing the clutch to avoid slack in the command. I already changed the clutch but didn't renew this pivot. Sounds not to difficult to renew it with everything back on the car but I just can't find any reference to it. Any help appreciated, thanks

You can renew it, but first the gearbox has to come off again I'm afraid. The fork, pivot bush and bellows are all renewable.

Any part nr for the pivot??? Coz I can't find it on VADIS. I'm pretty confident the pivot can be renewed with the gearbox still in place. Simply removing the slave cylinder allows to move the fork away (yet leave it in place for the thrust bearing!!). But I don't know how that pivot is fitted. Is it pressed in the GB housing, or screwed in?? I really can't find any information about this.

So this item is probably not supposed to be renewed when the clutch is changed I guess.... I still get some vibrations when engaging the clutch on hill starts and also when downgearing (esp. in 3rd). I'll have to have a more careful look at the motor mounts: both lower ones are new but the top ones have over 50'000km. I think this may be due to the top right mount although I don't really get much vibrations from the engine outside of these situations.
