I don't think it should when the system is pressurised.

Yeah the bearing was clicked on and then the fork placed after as the box was going in.
I'll give it a go though...ready to do just about anything short of pulling the box out again at this stage..

When I did my box, I did the bearing wrong, in order to get the slave on I tried levering with a crowbar, the clutch arm.
Point of story is, if you can move the clutch arm by hand with no mechanical assistance, you've done something wrong

Bearing onto the shaft and then the fork slid in.


Ok sweet!

Maybe im giving a bum steer then?

Pretty sure I did the exact same thing as I did with the STI...which worked fine.

Jase, care to comment at all? I really don't want to have to drop the box again... :dash2:

Yeah, I put a new gearbox in recently and when I was putting it back together I noticed a split in the boot of the slave cylinder so I figured I would get it reco'd before putting it back together..now it just won't bleed.

ah ok yeah looks like something below isnt done right

as adam said, it looks like its in its disengaged status and thats why the clutch goes to the floor

can you take off the rubber boot and have a look in?

but yeah you shouldnt be able to swing the fork easily

I'll pull the boot off tomorrow and have a look...given up on it today..ready to set it on fire.

When I move the clutch fork there is pressure there, but the fluid in the master reservoir just rises up. I can hear sliding noises when I swing the fork.

Thanks for the help guys :)

Topped up the master reservoir and bled it like Jase said earlier, then had a mate in the car pumping the pedal with his hands.
Built up some pressure, had him hold the pedal to the floor as I cracked the bleed valve (not that I had to, was sitting on the floor anyway). Then I put a piece of clear tubing on there so I could see any bubbles and what they were doing. After a while I had him push the pedal to the floor as I released and redid the bleed valve just to push any bubbles through. After putting 2 bottles through there is still no resistance and just snaps to the floor. He said there were a few instances where there was a bit of pressure but then it was gone straight away.

Hopefully that makes sense. It's the same way I normally bleed the clutches and never had any issues before now.

The clutch fork should want to push to the rear of the car naturally

Yeah, I can push the slave all the way in and the fluid in the master reservoir raises. The slave actually slides in quite easy?

Sorry, left work to get the kids.

This is normal.




Is it a pull-clutch or a push-clutch?

If I told you I was a compulsive liar, would you believe me?

Try bleeding it from behind the strut tower. There should be a nipple back there from where the clutch lines loop around. You may have a big air bubble there that just won't push down to the slave cylinder nipple and its just compressing when the pedal is pressed.
Also it doesn't sound like the throw out bearing has engaged properly (unless I'm misinterpreting) can the fork be pushed forward towards the front of the engine with no resistance?

Try using a tyre lever or similar to oppose the movemant of the fork when the clutch is operated and try to see how much force it can generate. It may not be a bleeding issue. Was it working after the box was installled but before the slave was replaced?

If you have a good brake line clamp, clamp the hose near as possible to the slave and try to operate the clutch. The pedal should be rock hard if there is no air in the master or line. (You could use some vice grips with cardboard in the jaws to protect the hose)

If I told you I was a compulsive liar, would you believe me?
