The Detailer Posted March 12, 2007 Share Posted March 12, 2007 I am going to be replacing my clutch soon and am woundering if any one has bought the clutch kit, or the flywheel from quadratec. If so, how do you like it. It seems to be a great deal for the price, compaired to the center force kit they sell. Jason :USAflag: Link to comment Share on other sites More sharing options...
Pete M Posted March 12, 2007 Share Posted March 12, 2007 Anything from Centerforce is going to be expensive. Link to comment Share on other sites More sharing options...
87manche Posted March 12, 2007 Share Posted March 12, 2007 Speaking as someone that's driven a centerforce clutch on the street: DON'T my god they're annoying. Centerforce clutches are designed for High HP and high performance, not daily drivers. It was grabby, it took 3 people to push and hold the freaking clutch in. I'm not bashing centerforce, it's a great clutch, but look at the designed application. Do yourself a favor and get something closer to stock, like a LUK gold kit or something.

The Detailer Posted March 13, 2007 Author Share Posted March 13, 2007 Thanks for the feed back. Right now I am looking at the OEM clutch kit from Quadratec. Funny story :headpop: November of 2005 I payed Phills Transmission to take out the tranny and replace the clutch with an entire clutch kit and resurface the fly wheel. My truck went back to their shop 12 different times to get the problem fixed. They do not back up there warrenty. My Jeep has a really bad clutch chatter problem. Soon I am going to do another clutch job, I'll also replace the flywheel, rear mail seal, and I'll put Mobil 1 synthetic in the tranny. I have learned that if you want somthing done right, you have to do it your self. The thing that pissed my off the most was I basically pissed away 900.00 dollars to have it fixed the first time.

Eagle Posted March 13, 2007 Share Posted March 13, 2007 You aren't supposed to resurface the flywheel on an XJ or MJ. I believe it says that right in the factory service manual. Everyone I know of who has allowed a shop to do that has experienced problems. It can't be fixed, because it shouldn't have been done but the shops aren't about to 'fess up and buy you a new flywheel. Link to comment Share on other sites More sharing options...
jeepthing07 Posted March 13, 2007 Share Posted March 13, 2007 When I swapped in a NV4500 into my YJ I had the flywheel resurfaced and put in a centerforce clutch and it never has worked right. Then I read about the flywheel being dished slightly from the factory. I have been driving it for years but it sucks and I don’t feel like dropping that 200 pound trany again to fix it. I would advise people NOT to resurface the flywheel buy a new one! Link to comment Share on other sites More sharing options...
comancheon33 Posted March 13, 2007 Share Posted March 13, 2007 I am replacing my clutch when I swap trannies and t cases in my 2.5 MJ in the next couple weeks and I am just gonna scuff the surface a little on the flywheel to help the clutch seat and thats it. I am not chancing my flywheel at all. Link to comment Share on other sites More sharing options...

I am not chancing my flywheel at all. When you scuff up the flywheel, inspect it closely for hot spots (patches of bluish discoloration). If you have them, the surface will be uneven and you'll always have chatter. That's why in the old days it was always recommended to resurface the flywheel. Too bad the new engineers think they have a better idea. Also inspect carefully for tiny cracks in the surface. Clean it up, get it nice and dry, then shoot it with water or brake cleaner or something that will temporarily settle in cracks and make them easy to see. If you see ANY tiny cracks in the surface -- buy a new flywheel. Link to comment Share on other sites More sharing options...

Tracker Posted March 14, 2007 Share Posted March 14, 2007 I had my flywheel re-surfaced and everything turned out great, (as far as I can tell and feel). After reading a reference to this curved flywheel surface thing I went to Kragen and AutoZone and laid a machinist's straightedge across the surface of new flywheels they would sell me for an MJ. Flat as can be, as is the one I just took out of another MJ. :dunno:I guess I can't just let the experts speak. Of course, if it blows next week...... :bowdown: Still, I'd be willing to bet that there are a lot of things we do to our MJ's that the FSM would disagree with...

jeepthing07 Posted March 14, 2007 Share Posted March 14, 2007 From the Factory Service Manual... Flywheel Inspection Inspect the flywheel whenever the clutch disc, cover and housing are removed for service. Check condition of the flywheel face, hub, ring gear teeth, and flywheel bolts. Minor scratches, burrs, or glazing on the flywheel face can be reduced with 180 grit emery cloth. However, the flywheel should be replaced if the disc contact surface is severely scored, heat checked, cracked, or obviously worn. Flywheel machining is not recommended. The flywheel surface is manufactured with a unique contour that would be negated by machining. However, cleanup of minor flywheel scoring can be performed by hand with 180 grit emery, or with surface grinding equipment. Replace the flywheel if scoring is deeper than 0.0762 mm (0.003 inch) . Heavy stock removal by grinding is not recommended. Excessive stock removal can result in flywheel cracking or warpage after installation. It can also weaken the flywheel and interfere with proper clutch release I'm am 99% sure thats what screwed my clutch up. I even stuck a washer as a shim under the fork pivot to try to bring the throwout bearing back to where it would have been before it was machined thinking that might have been the problem and it dident help at all. :dunno: Link to comment Share on other sites More sharing options...
87manche Posted March 14, 2007 Share Posted March 14, 2007 it was a stage II I believe, in a friends 427 camaro. It NEEDED a clutch that aggressive, because of the worked over big block, but I wouln't wish that on anybody that had to use it as a DD. From what I've been told the stage I's are still a PITA everyday driving. I've had 3 friends run stage I's on the street, 2 in 5.0 mustangs and one in a 350 powered f body. They all replaced them in favor of stock clutches, after their left leg started to dwarf the right. Speaking as someone that's driven a centerforce clutch on the street:DON'T my god they're annoying.
