- - Bad clutch (https://www.yenko.net/forum/showthread.php?t=87758)

Well it seems that my NEW clutch has gone south! A whopping 46 miles and its toast!!.. chattering, bucking, losing adjustment very stiff...and just does not feel right. I wont mention a brand name, but I am going back to the force! At least I have a couple of weeks between now and the reunion to make it right..just can't win. https://www.yenko.net/ubbthreads/imag...lins/frown.gif

Al,

I know that with a centerforce clutch...there is a break in period

see this from their website:

[ QUOTE ]
DO CENTERFORCE CLUTCHES REQUIRE A BREAK IN PERIOD?

Yes. It Is Recommended To Properly Seat In The New Pressure Plate &Amp; Disc Assembly To Assure Good Clutch Performance. Centerforce Recommends 450-500 Miles Of In Town Stop And Go Type Of Easy Driving Before Applying Full Power. If Your Driving Consists Of Mainly Highway Type Use, The Break In Period Should Be Longer Than The 450-500 Miles. If The Break In Period Is Not Properly Followed, Clutch Life And Performance Can Be Sacrificed.

DOES CENTERFORCE REQUIRE THE FLYWHEEL TO BE RESURFACED BEFORE INSTALLING A NEW CLUTCH?

Yes! Flywheels Are Subject To Heat, Scoring And Warping During Use, Therefore The Flywheel Should Always Be Properly Resurfaced Or Replaced To Assure Good Clutch Performance. Resurfacing Must Be Performed On A Qualified Flywheel Grinding Machine. Centerforce Does Not Recommend Resurfacing Flywheels On A Lathe Or A Blanchard Grinder. Also, Be Aware That Using A Hand-Held Electric Or Pneumatic Grinder/Sander Or Scuffing The Surface With Sandpaper Does Not Constitute A Properly Resurfaced Flywheel. Refer To Your Factory Service Manual For Specifics On Your Vehicle Regarding Flywheel Resurfacing And Specifications (Flat, Step, Etc.).Some Vehicles Require New Replacement Flywheels Instead Of Resurfacing. Please Consult The Factory Service Manual Or Call Our Tech. Line At (928) 771-8422 If You Have Any Questions

Appreciate the input..clutch is a Hays diaphragm ..new flywheel, new everything..it just keeps getting worse instead of better. Got to horse it out to be smooth.... tough to do on grass !!. New one is on its way..just another project for the weekend https://www.yenko.net/ubbthreads/imag...lins/dunno.gif. Thanks

Kevin, I have to admit I may have done a few https://www.yenko.net/ubbthreads/imag...ns/naughty.gif, but I have never broken in a clutch!! I just go out and drive it!!...just reinforces the two steps forward and one step back theory that has plagued this car from the start!!.

I have a under-car transmission jack if you want to borrow it. It was quite a relief after years of trying to bench press those cast iron, 18-spline Chrysler A833 trannies. They make those M-22's feel like they're made out of balsa wood. You're welcome to borrow it. It think I'm only about 20 minutes from you. PM me if you need it. -Steve

STeve, thanks for the offer.but I have a buddy coming over to "assist"..He's a Master Ford tech at the local dealer, we'll knock it out in no time, and these Muncies at least have some aluminum parts https://www.yenko.net/ubbthreads/imag...mlins/grin.gif. Thanks

That is a shame on the clutch deal Albert. Its always something! I like Hayes. There is one in my Z/28 now. Keep your head up. The bugs will get worked out. You have a great car. Sam https://www.yenko.net/ubbthreads/imag...iggthumpup.gif

One of the causes of early clutch failures is "hanging" the transmission while trying to get it seated in the pilot bushing. Just one second of off-center weight on the disc ruins it. That is why it is so critical to use a tranny jack or some other device to completely support the weight of the trans while you slide it into place. (I've learned from experience! https://www.yenko.net/ubbthreads/imag...emlins/mad.gif)
