Clutch pedal jammed

[Aussie Esprit]

Hi Guys,

I have a problem with my clutch which happened whilst driving everything was fine until the pedal completely jammed. 

I have a V8 with uprated twin plate clutch.

The pedal has some movement so I think the master cylinder is okay. The fluid level is about 4mm lower than normal.

Has anyone had this problem before? 

Any thoughts, do slaves jam up or could it be the release fork?

You need to break this into sections. 
is the master ok?, is the slave ok?, mechanical movements ok?
Don’t assume anything and work through it logically.

If you can access the bleed on the slave - then crack that off and see if you can  fully press the pedal. That will at least prove the master and the mechanism at the front.

Jammed up or down?

I had an S4s where the release fork broke in half because it's not strong enough but yours is different as it's a pull clutch 

You'll stand a better chance of an answer if you post the question in the V8 forum

Clutch pedal jammed in the up position. 

I will loosen the bleed screw to check the pedal linkages and the master.

Hi Guys, I've checked the linkages, the master and the slave and all work okay.

It looks like the the clutch fork has popped out of the release bearing.

Can i get the clutch fork out without taking the gearbox out?

I have an early v8.

You cannot remove the fork fully from the bellhousing in situ.  There is a slot in the fork so it can be moved up to disengage the release bearing for gearbox removal.

By removing he slave, you should be able to see the fork is engaged on the release bearing.  Pull it up fully to disengage and then back down to ensure it is seating correctly. You will see that it can only be seated fully with the release bearing in the correct orientation.  It does take some positive force to engage.

When seated correctl, once the slave is fitted it should be impossible for the fork to disengage during normal operation.  See the profile of the fork ends in the image below.

The 96-97 ball type clutch fork pivot will allow the fork to completely disengage and be removed from the Bell housing without removing the gearbox.

I'm guessing this was a design fault rectified on later cars, it's entirely possible that a sudden shock could cause the fork to jump off its pivot, it may be worth investigating.

I was glad I decided to move to the newer style fork/pivot after receiving it. Can certainly remove the older style fork from the pivot without removing the pivot itself. Newer style locks it into place.
