as mentioned, the washers were 0.069" thick -- I only used a single washer at each screw and so the effect was that the pressure plate was 0.069" farther out from the flywheel vs. what it was previously.

not sure how much pressure is exerted on the clutch plate with the change I made, but since the springs that push the pressure plate are pre-loaded, I do not think that the pressure is changed significantly. The washers I used were 0.069" thick by the way... I bought more washers than needed...

So...my analysis is that the pressure plate was not allowing the clutch to properly release -- not enough stroke to adjust the pressure plate to release the clutch disk... I could have just swapped out the pressure plate, but since this one was already balanced to the flywheel I was reluctant to...

The measurement from the flywheel plane to the pressure plate plane (with no clutch disk installed) is ~ 0.140". I got a friend to measure the same dimension on his V8 pressure plate and it was 5/16 (0.313). I called Bratton's and the person measured one off the shelf and it was 0.185". And so...

note on the second picture I removed the nut that was originally on that side, backed out the screw, and added a nut on the other side (which may or may not end up as the final configuration -- but at least this way I would not drive the fingers into the clutch disk, all other things being equal)

I do not see any shims, etc., here are pics looking at the pivot arm

mine is 3/8" -- same as the one you show in the picture

yes it is 3/8" -- same as the one you are showing

I saw somewhere that the raised lips were added due to springs jumping out and creating havoc in the other design...

On the first picture with the pressure plate mounted to the flywheel, you can see where the fingers are with the pressure plate tightened to the flywheel -- and yes they are fairly through their "stroke" which limits the amount that the release bearing can push. I did think about "install...

Thanks for the comments and ideas. Clutch was not in backwards -- as you can see from the pictures, the side that was scratched from the pressure plate fingers is the Trans Side... here are pics of both sides of the disk, which, like I said, apart from the scratches appears to be like new...

disk was installed correctly -- disk is not bulging -- it is like brand new except for the scratches

A while ago, I pulled the engine on my '29 Tudor, and took the occasion to have the flywheel modified and a V-8 STYLE PRESSURE PLATE (Bratton PART #: 11460) installed. In the description it indicates "Uses the same clutch disk (11400) as the stock one". I actually bought the clutch disk...

I am looking for options with my '29 Tudor with the 7-tooth box as well...have not decided which direction to take yet.

Lots of good info here. I am not yet at the point of thinking too much about this -- I am still working to get my car on the road...but once I do, I will probably come back to this thread and consider the options given...
