Reply to "Clutch Slippage"

Simply put. No. But if it is "an original" replacement clutch then the lining is refered to as "organic".

Organic is more susceptible to oil contamination.

Unless there is a very obscure problem with the assembly, such as one of the lining rivets not being countersunk properly the likeliness is that there is a contamination on the lining such as oil.

In all honesty. I had a truck that was constantly leaking oil into the bell house and the clutch was soaked with oil and I couldn't make the thing slip. So in theory a contaminant will cause slippage but judging from what I have experience personally, it won't.

If this is so then by the process of elimination there must be a mechanical issue with the clutch itself.

If I recall correctly. If you mic the thickness of a new center disc it should be just about .340". When it is worn out it will mic something like .320".

The Pantera disc with no Marcel might have less loss of material to be considered worn out but I'm not absolutely sure about the number.

You could take it all apart and examine it. Maybe resurfacing the flywheel will clear up the problem?

I know from my own experience that Pantera clutch troubles usually are a result of trying to use a 10.5 or 11' Mustang clutch, and that just ain't the way to go.

Anyway, good luck with it and I guess you will eventually be an expert on a Pantera clutch. You aren't alone though. Your're where I started out.
