Technical Flathead clutch won't disengage

hi
i don't know why but my clutch won't disengage. If i rotate the clutch shaft to the max it just touches the 3 bolt for disengagement
i have French flathead and a 39 tranny with a new release bearing.
can anybody tell what's wrong?
is the french pressure plate incompatible?
pictures show the clutch shaft in released position.
thanks Jan

 

Clutch disc in backwards?

 

I went nuts for over a year with a similar problem. Turned out to be a transmission was from a 6cyl flathead. The case is different. To check, look for a 1/4 hole in the bottom of the case.For a V8 case, this hole allows you to insert a long drift to drive out the pin in the throwout bearing fork. If that hole isn't in the bottom of the case, it's a 6cyl. trans

 

Does the French pressure plate look like a Ford 3 arm stock plate?
I think it might be the pressure plate is not compatible with the Ford disc.

 

Well, you didn’t say what vehicle this is in.

How about a shot of the pedal and linkage setup you have?

Maybe a combination of the wrong linkage parts.

the clutch fingers are up against the candle stick, they aren't even close to the throw out bearing !
Looks like the pressure plate is wrong , the fingers are to long & to close to the center !

 

Pete makes a good point. Looking at the picture closer the fingers could be hitting on the inputshaft retainer.

Maybe the pressure plate is for a 1 1/16” input shaft and not the. 1 3/8” that the flathead uses.

Jan,
Any update to your issue?

If the clutch fork is in backwards this will occur.

 

clutch fork is in correctly but appears to have the wrong pressure plate

 

Throw out bearing should just clear the three studs at rest.
