Technical Fiat Uno clutch problem

[BlindEagle]

I'm having a problem with my clutch. It started engaging lower and lower, until it wouldn't release anymore. I can get the car into gear if the engine is off, but the moment the engine is on and I push the clutch all the way in, no luck.

I have replaced the clutch plate, pressure plate and release bearing, but it is still doing the same thing.
I looked at the master and slave cylinder, but they are not leaking and the slave cylinder is pushing out all the way and pushing the clutch fork all the way.
I looked at the clutch fork and it has not jumped a tooth or anything, but it is rubbing against the gearbox frame about 1cm into it. By this I mean there is an outline of the fork arm that has worn into the frame over time.

I'm not sure what to look at any more. I have taken the gearbox out twice now in case things were not lined up, but they are.
I'm not sure if i put the clutch plate in backwards or something stupid.

Any help would really be appreciated.

Looks like you hydraulic hose is jammed .
Replace hose and fluid .

If the hose is jammed, why does the slave cylinder push the clutch fork as far as it can go? Could the fork be warn or bent?

 

[johorridoh]

Main-cylinder may be worn.
If you push the clutch , check if the slave cylinder keeps position over a longer period.
Is the connection between the lever and the clutch-fork ok ? Maybe it´s lose and slips.
That would be the explanation for a fading function.

A torn clutch fork is also possible .
This issue cost me a brand new release bearing .
Due to single sided pressure.
Left steered UNOs don´t have clutch but cable hydraulics
So a picture would be helpful.

It was caused by a faulty clutch plate. The splines were too small, so they wouldn't slide all the way down the gearbox shaft.

So you were to stupid to buy spare parts ?
Or was it the previous owner ?
(just kidding)
