Clutch problems

...The first thing I would do is check the Fluid Level in the Clutch Master Cylinder, to make sure we're Not Pumping Air. And then I would get a Helper to pump and Hold the Pedal, while I Bled the Slave.
That Should help some.
Then You can go on to other Checks...if the Master is the Original, Yes! The Fluid could be Leaking Past The Piston.
Others will be here to Help Soon!

..Oh, I just re-read..the fluid is NOT Low!
Could be a broken spring in the system somewhere. Pressure Plate Fingers. Could still be AIR in the System!

Webbers, from what I gather from previous postings from you. You have had continuous Clutch problems? am I correct?

1) Do you know how to properly adjust your Clutch and especially the Linkage related to the Slave Cylinder?

2) Do you know how to bleed the Air out of the Lines?

If you can not answer yes to the two above questions you need to ask someone to do it for you who can do it the published (correct) way.

If you can answer yes to the two questions and have done the work/settings I would in your case start from an end and check everything associated with the Clutch operation. (don't yet pull your transaxle of the Engine to check Throw out Bearing and Pressure Plate)
Start from under the Dash and check if the Pedal linkage is lubricated and no obvious damage or excessive play etc. Then disassemble your Clutch Master Cylinder and check it. Disassemble your Clutch Slave Cylinder and check that one also. Check the Hydraulic Lines that there is free passage (in both directions). With the Slave Cylinder away also check that the Lever moves freely.

If everything is in good order then the trouble could be the Pressure Plate, The Pilot Bearing or the Throw out Bearing or any combination.

The Clutch system on the Pantera is very simple but MUST be operating exactly to specs or you can expect a lot of issues and damage your Clutch or ultimately your Transaxle.

This is just the steps I would follow if I should give you an advise. I bet there are other ways just wait and read more posts that will come from experts all around the world

One thing to be aware of when dealing with master and slave cylinders. I am not the only owner that has discovered that after rebuilding one side of a hydraulic clutch system, the seals on the other end of that system decide they need to be rebuilt also.

Of course you do not discover this until you have completely reassembled and bled the system and go for your first drive.

I've come to recommend if you rebuild one that you rebuild both.

Just my two cents.

...In My case...Years ago, 'Hall Pantera' offered a Bundled Set. The CNC Aluminum Clutch Master and the 'Long-Throw' Clutch Slave Cylinders, Together, for a Huge Discount on Price.
I purchased Both and Installed them together.
In My opinion, the Best way to do the Job Right, and End the Problem for Good!
