  • Diaphram clutch?

    I plan on installing the clutch assembly, bellhousing and transmission [F**d 5-speed] onto my 289 tommorrow. I'm using a modified Stude. truck bellousing, flywheel and throwout bearing and have a used Borg and Beck type 3-finger pressure plate. Due to a mistake on my part I bought the wrong clutch disc 10 1/2" when I need a 10". My question is when I go to the parts store tommorrow to get the right disc can I use a diaphram type pressure plate instead of the B&G type I have? Would this work with the Stude. throwout bearing? Thanks,

    It will work, but you might need to grind the two bumps off the inside of the bell housing. Not sure about the truck bellhousing, but this needs to be done on the car. Also at that point an 11" clutch should fit. I am running a Center Force Dual Friction diaphram clutch in my Hawk right now.#13;#10;David

      Thanks for the info. I can use an 11" clutch in this bell housing? I ask because with the 10" one that I have the retaining bolts seem to be very close to the raised portoin of the pressure plate. I'll take the whole assembly to the parts store with me and test fit it. Again thanks,

        I took my flywheel and clutch setup to the parts store today. I found that 10 1/2" is the largest pressure plate my flywheel will accept. The bolt pattern on my flywheel is the same as a Chevrolet but due to the trans I'm using I'll have to go with a Ford clutch disc and a Studebaker throw out bearing. Since they offered no kit for this I'm checking back monday to see what they've come up with.

          Darryl,

          I didn't wanna respond until I'd checked my stash. Indeed, that housing will take on an 11" clutch. I have an extra truck flywheel here that's in nice shape. Surface rusty from bein' in the shed for many years, but looks like it has a pretty face on it![:X]
          I may even have a good PPlate and disc as well. Lemmee know!

            You will find that the actual clutch rebuilder people know way more than a parts store about replacing and modifying all type of clutches.

            They even have ceramic linings to replace the "paper" they use now instead of asbestos. My rebuilder replaced the original 12 inch clutch in my 7E13 '62 Transtar 1 ton dually and raised the pressure up to 2035 LBS. On a stock truck flywheel the pressure plate barely fits with cutouts for the bolt holes, but it matches the factory installation. So I know you can go more than 10 inches, that is for a 259, 289's get 10 1/2 with 11 inch as an option on HD trucks. Mine is a special factory order 12 inch. And is on the original build slip.

              I guess I'll just go with the 10 1/2" set that the parts store comes up with. I don't see how an 11" pressure plate could fit the flywheel I have. The disc would be into the retaining bolts but I'll have to use this flywheel as I've already paid to have it balanced with the engine assembly.

                Darryl; that must be the old small flywheel for the 9 1/4 in. 232 clutch. Were you able to get a fine toothed 12V Starter ring gear on it?

                  I ordered this flywheel from one the forum guys a year or so ago. Its supposed to be for a 12-volt starter. Is there a way to tell by counting the ring gear teeth or by the diameter? Thanks,

                    A flywheel for 6 volt V8 will have 133 teeth. 12 volt will have 162 teeth. Are there any casting numbers on this flywheel?

                      Its a 162 tooth with no casting numbers.
