Y-Guys       Are all "long" style pressure plates the same? Will

         a diaphram type work and hold 350/400 ft.lbs. torque?

                  I have an 11" long style in it now.

                                Suggestions

                              Thx in Advance

I'm also interested in this topic. Does anybody know of an 11" diaphragm clutch that WILL fit the stock 292 flywheel bolt pattern?

I just did some searching around and found this 11" diaphragm clutch that looks like it'll fit a stock flywheel pattern!

Bill,

I only know one of the answers to your three questions.  Yes, the diaphragm type will work, I use one and purchased from John Mummert.  It is for an 11 inch clutch but it requires a smaller diameter throw-out bearing surface to make correct contact with the pressure plate fingers.  If my memory serves me right (I keep my fingers crossed a lot) it was all mustang.

For my 11" with T10 I got one for a 63 Galaxie with the 406. It was not fingered but the FE 11" pressure plate bolt pattern is the same, so if they make a fingered one for that it should work in a Y.

Nope. But an 11" should bolt in place of another 11". The same goes for 10". The fingers can have a different spread, depending on the input shaft size and/or throwout bearing for the application.







The right one will. Here again, they are not all the same. I'm sure some are made which will mount in the place of the long plate. If this is for your turbo truck, I suggest that you look at the Centerforce Dual Friction. I'm loving mine so far. The pedal effort is no more than it was stock.

This alarms me. J. Mummert is installing 11" diaphragm clutch on my stroker shortblock, and has assured me it will bolt right in to my '55 without throw-out bearing alteration. JOHN...???

A car should already have a bearing appropriately sized to work with a diaphragm plate. It is the trucks, with the larger input shaft, that will have a problem.

Y-Guy Charlie:        I've sold Centerforce clutches, for years, when I was

                  in the 4x4 business. Do you have a record of the part number(s)

                  you used. I've got a T-5 same as you, so it should work!

                                               Thanks Bill

The clutch I'm using is actually for an 80s mustang and will not bolt in the place of an 11" long clutch. The part number is DF021048.



I think DF700000 will work in the place of an 11" long plate but please check with Centerforce before you order one. It is an 11", 1 1/16 - 10 spline clutch. One of it's application is F100 - F550, 1965 - 1977 with 300 I6, 352 and 358 V8. I believe those would have been equipped with an 11" long plate originally. This clutch also fits many other Fords.



Gary may know the answer to this.
