Question Are the supplier's "v8 STYLE pressure plates" really for tractors?

I was reading this:

http://www.fordgarage.com/pages/pressureplates.htm

Do any of the suppliers currently sell real v8 pressure plates (rather than "v8 STYLE") that have flyweights, or they all sell the inferior tractor ones, as described in article above.

I guess the best thing to do before buying is to ask and be sure. I think the better shops will sell the correct parts or at least be upfront about their products.

Having owned a Ford 9N tractor, I would have to take umbrage to the "inferior tractor ones" according to the OP. That said, Bert's has the V-8 pressure plates. My flywheel is 28 pounds.

The tractor clutches don't have the weights on the fingers that V8 clutches have. They increase the clamping force at higher RPM's. I recommend diaphragm clutches, they are much smoother, clamp well and take less pedal pressure to operate them.

Hey Jim B,
I agree on both points that you've made here.
Centrifugal weights were/are improvement over 'tractor' PP, that's obvious advancement.

I lost my spec info as to which diaphragm PP you used (year/model number).
Can you issue that to me again please.

Bert's website says "v8 style pressure plates"...do these have flyweights?

Hardtimes, mine is a #07017D bought from Clutch Masters in Rialto, CA. They machined my flywheel too, I furnished one already cut for a V8 clutch.

The so called tractor style have pressure plate pivot points secured by cir clips. The V8 with the counterwiegits have the pivot points secured by cotter pins. I had a cir clip come off. Clutch would not release. Towed home. V8 pp are available at Ft Wayne Clutch, google it. The have a "kit" includes TO and pilot bearings and clutch.

Check with Brattons first. I bought a pplate thinking it had the counterweights because of the picture, and it was the tractor type when I received it. Maybe different now.

Problem with the disk shown, IMO /experience, is that springs are not ‘captured’
by the metal tabs. When the springs fatigue / rattle, over time, they can fall out of place and into the works.

Do original v8 PP have "captured" springs?

The picture seems to have flanges on the spring openings. Those do not capture the springs?

Thanks for the info.

Here it is:

It says the PP is "reman". The new Bratton PP looks very similar.

I have a original Ford disc (v8)in my A, it was in the car when I got it 50 years ago, I took the picture when I was trying to get it unstuck, drove over 40 miles jerking it, still wouldn't pop loose, had the car bucking jumping on- off gas, then I learned that I could shift without grinding, that the starter did fine starting from a stop in gear, I tapped the hole in the picture , put a bolt in it and yanked, and it popped off the flywheel---- the original Ford disc doesn't have spring capture flanges, and neither in the box nos ones don't have them, perhaps the springs are better, the metal thicker than modern production --- in the era it was common to replace just the facings on old disc
Yes, I drove nearly all the 40 miles with my foot on the clutch and no change in crankshaft end play
