OK, I'm trying to get to the bottom of my clutch issue, the fact that it wont allow me to change gear.
So you know, the slave cylinder has been removed and replaced with a hydraulic release bearing.
So, I've got the gearbox off and there is a small pool of fluid around the adapter for the bleed pipe.
However, I have video proof that the bearing is being pushed out when the clutch pedal is pressed... see here - http://www.youtube.com/watch?v=sw0IHkt84CA
Ok, so on that video, you can see that the bearing is pushing out nicely, and is moving the entire clutch assembly.
We've also viewed the operation by removing the lower end plate so you can see the flywheel. This confirms that the whole lot is moving. The flywheel is pushed in quite alot when its pushed all the way.
The clutch spring fingers have a contact mark on them, so its definately been in contact at some point. Not sure if its a permanent contact bearing, or if this is from the pressure of it pressing during "normal" operation.
I'm going to remove the clutch and make sure that the plates slide nicely on the splines as this can cause a problem of them not moving freely and essentially caausing the problem I'm seeing.
I'm also going to make sure the friction plates aren't rusted or fused onto the pressure plates.
And also going to bleed the cylinder again after PFTEing all the joints to make sure they're holding. Then it will be minimal loss when putting it back together.
At first inspection though, the only problem looks like a small pool of fluid that is coming out past the adpater on the bleed line. And for the amount of fluid we've put through it ~10ltrs This is a minute fraction of a percentage to leak out. I know it still constitutes a leak, so it will obviously be addressed.
Still stumped. Wont be happy putting it back together without knowing what the problem was for 100%
Ok, on closer inspection, there is also a slight run from the inlet pipe to the bearing too. Could be a case of shit connectors as we had the same problem with the bleed nipple.
Sorry for the waffling
