Thank you all for the help. Ben

Newsflash! Ben, I just pulled my dash1. It has a set of springs on the crosshaft that holds the throw out bearing. I'm installing the dash2 and inquired about the springs because they are not on it. S Wilkinson said they don't use the springs on the dash2 and Ford sent out a TSO to remove then from the dash1 because of pedal effort. I ad libbed the last part, but I can see how they would increase pedal effort. Too bad the tranny has to come out to remove them.This pic dash 1 with springs

Should I remove these springs from a dash-1 in a Mangusta?

Steve told me that I do not need them on the dash2. He said Ford sent out a TSB back in the day. The concern was pedal effort. They seem redudant to me too. Don't do anything just 'cause I said so. Tell you what else. I can press back the clutch lever on my dash1 with the springs with 1 hand. They don't make a whole lot of resistance. Bill

On my Mangusta ZF, which will hopefully be going in soon, the springs are actually pretty stiff.

I will push on the T/O bearing later on, and let you know how many seconds the red marks stay on my thumbs.

Then we will have a true criteria to measure with.

I pushed mine with the tranny on the table and did not have to disengauge the clutch too. You won't be moving anything with it installed. That's why I think It may not be a big diff. Anything would help. When I bought the first Centerforce I was expecting a big diff but My leg still cramps in traffic.

I don't think that the springs in the bellhousing make a lot of difference. You can compress them with a single finger, surely not a big deal for a hydraulic cylinder. I left them in the Mangusta to ensure that the T/O bearing backed completely away from the pressure plate. I have been told that the effort reduction kit only helps with the initial movement of the pedal and does not help the overall pressure.

I actually think that those springs are to make sure that the throwout bearing fully returns to the home position.

The Center Force is lighter then what was in my car when I got it. It would be interesting to read pedal pressure differences from car to car and clutch to clutch.

I think in one of the Ford shop manuals, maybe the Lincoln Versalles, the brake pedal pressure gets measured in order to verify it is within design specs.

I know that from working on a lot of Ford Power brake systems from the '70s that the brake pedal was considered correct if you could put your other foot under it while applying the brakes.

I don't remember seeing a number on any clutches , ever, but that is an interesting thought.

I'd bet you a bright shinny nickel Billy that the Center Force is something like 30% lighter then the original Long three finger in the car?

No one ever said that would be as light as a VW Beetle. Bill. Your leg doesn't cramp with that one too does it?

There are (at least) two Centerforce clutch covers that fit Pantera or Goose, and one is pretty soft while the second is competition- grade stiff; stiffer than a std. Long clutch. This one I would not recommend in anything less than a pumped-up big block. Do you know for sure which clutch cover you have in there? 'Cause if its that stiff, you don't need it unless you're racing for money with a highly pumped engine.
