clutch disk

A photo is not really going to be enough to tell.

do you have a part # or source, etc of what you bought?

And again I want to mention that if you are in any size of town with some good truck transmission shops, they can most likely rebuild a clutch disk, and pressure plate, for much less than a new set. And this has the advantage of using parts that you know already work.

I did that several years ago with original De Tomaso parts (yup the PP even has an Isis on it) and have had no problems.

No part numbers on the disk itself. If I had a disk to rebuild I would do that. I replaced the clutch disk after I had the trans rebuilt and still experienced grinding into gear. I was told by the previous owner that it didn't grind until he had the engine rebuilt and then had a new clutch and pressure plate installed. He also had the flywheel turned. I have been told that you can tell the difference between a Pantera clutch disk and a Mustang disk by just looking at it.

Note the Isis at about 11 o'clock near the finger.

Note the lettering at about 2 o'clock - "MODEL 11CF"

11 for diameter, CF=??

As I recall, CF stands for "centrifugal fingers", or "Clutch semi-centrifugal release Fingers". These are the clutch release fingers (3 of them) that have a weight attached to them so that at high rpm the release fingers place additional pressure on the clutch pressure plate.

Thank you!!!

Would it be to much to ask for a shot of the clutch disk itself from a side veiw. I would like to see the thickness of the disk.

Thanks again!

Sorry didn't take one from that angle.

And nice as I am, I'm not pulling the ZF to take one...

I just replaced my disc with a JEGS 049055-107 10.5" 1 1/16" 10 spline for $86.99.
this went under a center force Diaphram pressure plate, typically a mustang size clutch.
I used a sanding disc to rough up the pressure plate as a quick fix. 30lb dual pattern flywheel.

I will be going back to the 11" clutch with the new motor to handle the HP. I like Hayes!

Seems the disc is about 5/16". What matters is the splines and OD of the shaft

Larry,
Can't say I blame you! Thank you so much for the replies!!

Thank you too Sick Cat!

The best advice is call a vendor.
My understanding is that a Mustang/Torino disk is thicker and you will have trouble disengaging the clutch enough to shift into 1st and Reverse. Not enough throw at the slave cylinder. A lousy problem to discover when you have just reassembled your drive line. Even though I had a new, correct clutch when I reinstalled my ZF, I still had some "drag". I installed a long throw slave cylinder and drove it a few miles. Now everything works great. I still find I need to shift into 1st before shifting into Reverse to avoid grinding...especially when the car is cold.
I'd call Pantera Performance in Castle Rock, CO. Dennis is an expert on ZFs and will know exactly how to tell if you have the right clutch disk. (303) 660-9897.
Later, Mooso.

Thanks Mooso,

I have purchased and received a long throw slave and new master cylinder. I compared the parts and think I already HAD a long throw slave. My new master is very different from what was on the car. The one on the car is obviously not an OEM part. Once I get it installed (line fittings are not the same) I will let you know if it works.
