The Ford Barn

bob1972 · 08-23-2019, 11:49 AM

I want to replace the pressure plate setup in my 1935 Ford pickup with a 1948 flathead in it. The actual plate measures 9 1/2 inches. I ordered a 9 inch plate...it's too small. What to order? Where would I find the 9 1/2 inch plate for sale? I've seen 10 inch and 11 inch plates in catalogs, but not 9 1/2.

Thanks
Bob

What size was the disk that came out? My guess is what you have is a flywheel that accepts a 10" clutch.

I think deuce roadster is correct. If 9 in. is too small and 11 in.is to big, 10 in. is probably correct.

If it's a 48, then WHICH 48? If it came from a car, it would be a 59-type. If it came from a pickup, it would be an 8BA. Check 8BA clutch stuff. I think you will find a 9-1/2.
If it's 48 car, 59-type, it was originally equipped with a 10-inch. If it's an 8BA, look at 49-up car clutches.

My go to clutch people are Fort Wayne Clutch. They will rebuild what you have or send you what you need.

I got a 9 1/2” for a 8BA from Fort Wayne......Mark

Haven't heard anything negative from fort wayne stuff.

deuce_roadster · 08-23-2019, 10:28 PM

I never have owned an 8BA nor heard of a 9 1/2" old Ford clutch. Learned something new!
Bob1972, is that engine an 8BA?

bob1972 · 08-24-2019, 07:02 AM

Yes, the engine is an 8BA. I'll contact Fort Wayne Clutch. Thanks!

Dual Friction Clutch Includes Pressure Plate & Disc
Part Number : 183-DF021221
I couldn't be happier and the price was right from Jegs (drop shipped from Centerforce).
They pretty much have all transmission applications (disc) covered

The 9 1/2 was popular in the 8 ba engines, and is a good clutch in it's stock form and lighter than the 10/11" . However they di have a different bolt pattern than the early 9" so the flywheel had to be redrilled for use on an early flywheel. Now tha i said all that. I don't know if the fingers will clear rhe early 1 3/8 input shafts. The one I have is in a 59 with a T-5 trans. At present I haven't driven it so??????
