Pressure Plate Wondering which is the superior design....9" '34 Sedan - Street

Re: Pressure Plate I ordered a replacement clutch from RAM and they sent me a three finger design (like number two). I believe the original clutches were three finger design, but I can't say that for sure.
The three finger design uses the centrifical force of the spinning clutch to add pressure to the pressure plate - as the engine speeds up, it pushes down harder (you can see the weights in your picture). My upgraded engine will use a diaphragm style of clutch (sort of like your picture #1, but with fingers all the way around). Apparently they are easier on your left leg. ;) |
Re: Pressure Plate Won't it depend on which flywheel you have?

Re: Pressure Plate Never saw one like #1.
Stick with #2. |
Re: Pressure Plate #1's started with 29 A's, went thru 34. 28 A's were the multi disk things the early racer's liked

Re: Pressure Plate I think I found my answer at the Fort Wayne Clutch website.
#1 is for a RECESSED / STEPPED FLYWHEEL #2 is for a FLAT, NON-RECESSED STYLE FLYWHEEL |

Re: Pressure Plate Thanks for your reply, Mike. I won't know what flywheel I have until I pull the tranny - my flywheel could have been replace sometime in the past. I'm thinking that if I do have an original recessed/stepped flywheel, I would be better off replacing it with a flat non-recessed style. Am I correct in assuming the original flywheel is strictly for a 9 inch clutch and that the 35-up flywheel will accommodate a 10-10 1/2 inch clutch?
Do you sell a kit that includes the 10-10 1/2 inch flywheel with ring gear, clutch disc and pressure plate? |
Re: Pressure Plate The Long style applies more pressure to the clutch plate as RPM increases due to the fly weights, it is a much better pressure plate than the Borg Beck.

We sell clutch kits but in terms of flywheels, all I would have are used ones |
Re: Pressure Plate Today I removed the clutch from my 1934 ton and a half truck. It has the Borg & Beck style with 6 fingers (#1). The plate measures 10". Green book tells me this was truck only as is the flywheel. I haven't looked for a replacement as yet. I
