.060" is the standard, but with my experience, as long as the throwout bearing is NOT riding on the pressure plate and when you push the clutch pedal in, you can shift gears easily, you are good to go. Usually you will have about 1/4" free play at the clutch fork and about 1 1/2" of pedal travel up top. My 2 cents. Good luck.

Are you sure? The service manual is talking about a Bourg, and Beck with an over center spring, this is a diaphragm without a over center spring. I know Mcleod says 1/8 to 1/4 between the fingers, and the throwout bearing. But Centerforce doesn't say anything, and when I call they just said follow the service manual, but that was for a Chevy. Centerforce IS a Chivvy clutch, give me Borg & Beck or give me death!

I use to shoot for .030 on the feeler gauge bewteen the clutch disc and pressure plate or flywheel on RACE DISCs, Most Mopars wth B&B clutches will work well with .060 to .125 between the throw out bearing and prsesure plate fingers. I put a new Center Force clutch set in my 1969 Dart GTS last year, I need to remove the over center spring now to get the clucth pedal to not stick 7/8 the way up from releasing.

If you havent run one dont knock them.They are a great clutch I never measure.Just adjust till I can shift into Reverse easy as soon as it does its set.Clutches last a long time doing that.The CF I have now is about 15 years old and still flawless.rocky

Most of the experienced posters are right, IMHO. As long as the throwout bearing is not riding on the clutch fingers, whatever style, it has enough clearance. I don't measure, just set it up to touch and then back off a little.
As far as clutch design goes, I associate Long style pressure plates with Ford. But Chrysler and GM have both been using Borg&Beck and diaphragm clutches for years and years. Neat thing about them is the bolt pattern is the same so they can interchange. Another neat thing (mainly for trucks) is with an 11" clutch you can upgrade to a 12" disk just by buying the 12" clutch set, it's a bolt-on. This is for the 143 and more tooth flywheel. The 12" Borg&Beck in my '64Dog is a McLeod, but there was also a rebuilt 12" B&B from an early '60s chevy truck that I was watching on ebay. Turns out the McLeod was just a few dollars more, so my pressure plate is now red rather than blue.

Don't get too caught up on measurements. This isn't rocket science.......

Maybe when my knees finally go I will have to use one, but I still like the feeling of a clutch that matches the rest of the drivetrain...

The main bad thing about diaghram type clutches is when racing and speed shifting them is if they go over center the clutch pedal sticks to the floor with the clutch disengaged, NOT GOOD AT ALL. Been there, done that, more than once when driving(street racing) someone elses Chevy car back in the day, never ever had that happen with BB or Long style clutch.

I've been wailing on my Center-Force for over 10 years. 7000 rpm shifts. Never sticks, best shifting A-833 I've ever had. Doug

The last Centerforce clutch I bought lasted <30 days, a big POS... It went into the dumpster.. Now all we run are McCleod Borg & Beck, a little old school and takes more pedal pressure to disengage but they work well.. Just my $0.02...

dvw I do the same with mine I usually shift at 6800 to 7200.Never had a problem.I had a 3400 pound McCleod in it before.The CF bites better and is light to hold.30 days you should have sent it back.Rocky

Now all we run are McCleod Borg & Beck, a little old school and takes more pedal pressure to disengage but they work well.. Just my $0.02... It lasted only 30 days? What happened to it? Mine has at least 100 passes with slicks. No rocket but a nice street car runs 12.50@110. I've beat this clutch as hard as any I've ever owned. I never had a clutch go more than a year or so until this one. Doug
