Technical Flathead/T5 racket – fool me once...

Below is a picture of a "straight finger" diaphragm plate and matching disc. This finger design allows using large T/O bearings and inputs. (These Centerforce parts shown are specific for early big input Fords/Mercs. using '49-'53 Merc, re drilled Ford or aftermarket flywheels)

 

ok. i measured the adapter after i machined it. the area that i machined measures 11 5/8" diameter at the top, 10 3/4" diameter at the bottom, and it is 7/8" deep. i hope this helps.

Here you go.
The CA30 Pressure plate is a 10" diaphram unit. It has the same bolt pattern as early Ford. The stock throwout bearing is also used.
The original application for this clutch is 83-97 Ford Mustang, and many others.
As far as is known to me and my great NAPA guys, it is only available as a rebuilt unit.
I think I paid about 40 bucks for mine, works great.

He has a pretty good write up on the same swap and problems.

 

Nobux, there is something wrong with that article and the pictures. A CA30 PP does not need a stock Ford flywheel to be redrilled.

 

I just received my pressure plates for comparison. As said above the, CA30 diaphragm looks like a good way to go. Bolt pattern, finger height and the inside diameter of the fingers are all comparable to a Long 10" 3 finger PP. I also got a rebuilt original but because the re builders are replacing the fingers with new after market fingers. the rebuild looks identical to a new pp I had on the shelf. I used to offer diaphragm pp's as an option to the Long but there was little interest. I think I'll start to offer the diaphragm pp again, maybe that will stop some phone calls. Also I just remembered I ran this CA30 PP in my blown FH deuce roadster about 10 years ago and activated it with my hydraulic slave assembly, very light pedal pressure was required.

subscribed as I am about to do this swap.
Will be going with Cornhusker from what I have read...

 

nice touch...

 

Question on the CA30 PP.
Can they be used on a flathead with a '50s 3 speed top loader (open drive) and hydraulic slave assembly?
If so, would this reduce the pedal pressure?

 

I suppose the point is moot now, but Gary at Cornhusker rod and custom has the best kit in the country. As you said "a class act" and also great service after the sale reputation. He has helped me through several projects and most of my cars has had one of his chassis under them. I hope in the end this all works out for you. Speedway is a great source for name brand products otherwise buyer beware. Gary

 

Thanks Kevin. Will the CA30 pp be suitable as a replacement for a long style bolt pattern 59 series flywheel and a 48 or 78 part number 3-speed early Ford transmission case and stock throwout bearing and fork?
