pressure plate options Q... Anyone using a 'diaphram' type pressure plate in a model A/B? Any problem and/or benefits to it over, say...ford with counter weights?

Re: pressure plate options Q... What are you looking for in a different plate? Better clamp? Less pedal pressure? You know the 8BA used a 10" clutch and plate to match. The small block Chevy used a 9/10/11" clutch and plate to match. I think Joe Way uses the diaphram plate in his conversion as could I.

Re: pressure plate options Q... The advantage I see in a diaphragm clutch is that there is less pressure required to hold the clutch fully disengaged. I see this as an advantage in less foot pressure and therefore easier on our old knees, and less pressure on the crankshaft thrust bearing.

I'm OK with my Model A stock clutch, but I must say that when I drive my friend's 49 Chevy pickup, that cluch is a real pleasure to operate, and I wish it was in my Model A.:) |
Re: pressure plate options Q... I never hold the clutch even waiting at a light. Holding the clutch in puts pressure on the rear thrust and will deteriorate it sooner than just shifting to neutral.

Re: pressure plate options Q... I recently put one in my tudor. It is much smoother than the stock clutch that was in the car when I bought it and also smoother than the V8 clutch that I had put in. It does have a slightly odd feel to it but worth the change. Like James, I don't hold it down at stop signals.

Observation POSITIVES: regarding diaphram type vs finger(s) type. I'm not an engineer, but common sense tells me that the 'multiple' contacts of a diaphram pressure plate would be easier on the throwout bearing(i.e.-distrubuting force); would provide better mechanical advantage(ergo less leg power necessary), more even pressure/less wear on clutch disc. Negative: the 'counter weights' on the three finger pressure plate provide MORE pressure (centrifugal force) on the disc...as rpms increase. Better clamping force? Whereas , diaphram type doesn't have counter weights. Am I wrong in my observations? |
Re: pressure plate options Q... I have thought about this. Here is a link to a post by Joe Way.

Re: pressure plate options Q... I have one of the diaphram type PP going in my rig this weekend.

Oooops, forgot to mention that my installation will be on a B engine..if that matters, not A setup. |

Thanks for that! Interesting reading:)! |

Yeah, that's what I'm thinking about! Thanks:) And, thanks for the PM. |
