Centerforce Clutch ISSUES!!!!!!!!!!!!

    Well i frickin spoke too soon. I thought i had the jeep running. Well i put the driveshafts back on and cranked the jeep up, and i expected to be able to put it in gear, but NOOOOOOO The frickin thing will not cooperate. But if i put the jeep Tcase in Nuetral, i can shift it into gear all day with the clutch. What the hec kis going on????? I am talking to Billy bout this and trying to figure the problem out. I noticed when i took my tranny out last time i had the disc spline hub (center thingy) rubbing on the little weights that are on the fingers of the centerforce pressure plate. You can defiantely see they they are hitting each other. So first thing i did was swap out discs. I put a stock ford mustang disc in. With this disc i found out the center hub is 1/8 smaller in spline hub length. But i didnt see if the smaller length was in the front or rear. So it looks like the smaller part is in the rear. So I have to options.

    1. Machine or grind the center hub on the disc to not have the little weights on the pressure palte contect it. This is what i believe that is preventing the clutch from engaging.

    2. Remove the little weights on the fingers of the clutch. The weights look to be easily taken off, now would this hurt the function of this pressure plate?? Or are these weights just there to remove vibrations.

    Any way the little weights are hitting the center spline hub.

    How do I rememdy this??

    Or I could go get a stock 225 pressure plate and use that?? By chacne does anyone have a 225 pressure plate laying around they want to part with for dirt cheap or free????

    Oh why oh why do the jeep God's dislike me :( :( :( :(

    A stock 225 diaphram style pressure plate works fine with a 10.5" mustang clutch. That's what I ran when I had a T18.

    Aren't those little weights thingys actually the reinforcement for the throwout bearing contact area, and not actually weights at all? Or am I misunderstanding what you're saying? Didn't Lafester have this identical problem a while back?

    I can definately say it isnt a hydrolic issue. i had the tranny out and i measured the throw the bearing had from beginning to end and i defiantely would have to disenaged when i put the pedal in. Those little weights can be removed in a second. I can see them scarred on the bottom from hitting the center hub. Wrost thing is i have to take apart the frickin jeep again, boy is it a PIA!!!

    Here is the picture of th epressure plate. The weights are on the fingers. i read the centerforce website and they say not to take them off, but looking at it they will come off then it will be a regualr pressure plate. the weights will bring the figners towards the tranny under RPMs to keep it clamped, so if i take them off i do not have the extra bit or clamping, but it will be regular. and the pressure plate is labeled as a Luk plate. so was it rebadged??

    Did you get the clutch disc from Centerforce as well?

    The attached iamge in the previous post is almsot exactly what i have. The little weights are hitting the splined hub on the disc. See where the weights are, they will contact the hub when the figners are pushed in when trying to engage the clutch. So picture them just riding on the outer hub.

    Here is an attached picture of the disc. The pline hub is what the arrow is poiting at. It is getting rubbed by the weights. you can see some damage in the picture.

    The original clutch disc i got was from centerforce. that is th edisc in the picture. then i have heard that people had problems with the centerforce disc, so i got a stock mustang disc and the spline hub was 1/8 shorter. But i was not sure if it is in th efront or back (the length differnce) But now with the stock disc i am having the same problem. Suppsidly the componants are matched to each other so i can see having problems because i am using a GM v6 pressure palte and a Ford disc. So either i can grind down the spline hub (or machine), remove the weights, or go get a stock pressure plate. The problem is the weights and spline hub.

    You sure you don't have that disc in backwards? That picture looks like the flywheel side of the clutch disc.

    I can gurantee it is not on wrong, flywheel side is engraved on both discs, and i made sur the one i just put in was correct.beleive me i wsh it was just on bacjwards. what is happening the little weights are pushed in and hit the spline hub and cannot go any further. th weights are about 1/4 inch or larger in side, so that is 1/4 + of an inch that is not letting the clutch relase the disc when pushing the figners in. :(

    Well, I sure wouldn't go grinding on any clutch components unless you are running a scattershield. I'd take back that fancy pressure plate and get a regular one.

    I'm glad you posted the picture of the pp. Those weights aren't what I was visualizing. That's screwy, the matching disc doesn't work because of the PP design. :?

    DanStew Preowned Merkin salesman Staff Member

    Yup not matching, i guess if i had the 225 disc it would work fine because they are made to match, but since it is a Ford and GM marriage it is not working. But should i just try taking the weights off, grind down the spline hub or go with stock 225 pressure plate???

    I believe the weights are to help maintain pressure when the engine is reved up to high (race) rpms. I don't think they factor in on the kind of engine use we have. I think Centerforce is highly overated and I would never spend that kind of money on their stuff again. As you rightly noticed, the clutch disk doesn't look any different than your basic over-the-counter NAPA part. IE; made in China. As far as the difference between the GM and Ford configuration, I doubt there is any real difference except the center hub spline count and size. But, I've been wrong once before!

    I say if Centerforce can't sell parts that work then go with a standard pp.

    OK Guys. I am going to pull the clutch again. and take the weights off and try that. I read that also that the weights only help at high RPMs, which i am really not going to do. So what do i have to lose really, i will pull the weights and hopefully it work, if not i get a stock pressure plate. Really does hurt, you think buying a "Better" clutch to get a little more performance (i.e. I wanted to sticker to add 5 HP) and this crap doesnt work. I think i will reinstall the centerforce disc also at the same time to maybe be able to use that part. Boy i am tired of taking this heavy pig of a transmission in and outl. Wish me luck!!

    I'd sure be sending that Centerforce PP back for a refund. Then, I'd use half of that refund for a stock PP, and the other half for beer!!!

    You paid extra money for the "weighted" Centerforce PP, if you remove the weights, you're left with only a stock PP. Why pay extra for that?
