New Clutch Slipping, Please help

1460 Views 11 Replies 5 Participants Last post by  Clipse3GT
So i just installed a brand new gripforce clutch and pressure plate, i got it off a friend and he didnt give me a throwout bearing. i spun it and it seemed like it was still good. i have a 03 62000 miles on her. now the problem is if i try to bang gears or if i give it gas while moving the motor revs up like im not in gear then i let off the gas and then the clutch will try to grap but it doesnt till it gets low in the rpms like 2500 or so. i have tried everything i could to fix this and i cant figure it out

did you do the breakin period before beating on it?
the clutch started to slip right out of garage. like i was trying to take off slowly and it was slipping, so i put it in the garage and started to do some adjustements the pedal, reblead the slave cylinder, add a touch more of trans fluid and now its a little better, but still its slipping, its kinda like over the miles its gettin better, i have about 200 miles on it now, but its very agrivating cause ive never had a brand new clutch do this before
Sounds like its not installed properly and not engaging fully. Better drop the trans and redo it.
what could have gone wrong? is it just that the pressure plate wasnt seated properly or what?
did you clean all the surfaces when assembling?
no i didnt clean the surfaces off at all, the guy i got the clutch and assembly had put a grease of some sort to stop the pressure plate and clutch from rusting over the winter, and the flywheel had the cutting agent on it still from the machine shop, i didnt give it a thought to clean them off, but shouldnt that stuff wear away, or should i take the fork boot off and spray some rubbing alchol down there or what
all the mating surfaces should have been cleaned, there's a good chance that your flywheel is glazed from the clutch and will need to be replaced.
what do u mean by glazed? is there where the new clutch sliped on the flywheel and made it a smooth surface or what
You always clean off any surface from grease or other liquids before installing. Brake cleaner works wonders + shop towels. Plus when doing a new clutch install. Have the flywheel resurfaced to have a proper mating surface for the clutch to engage in. I doubt there is much you an do beside drop the trans and redo all this.

:agreed: 100% Hopefully they can just be removed and cleaned though :scared:

My understanding is that the slick chemicals/grease/etc could have been heated by friction and then "baked" onto the clutch "gripping pads" (I forget their real name). This would mean that instead of the clutch having a sandpaper type feel it would be more like glass. Obviously a glass-like texture (glazed) would not have any gripping properties so it would not grab the flywheel and rotate as intended.

My suggestion would be to drop the tranny and clean both the flywheel surface and more importantly the clutch surfaces. I have also heard that brake cleaner and shop towels work well for this. Make sure you use towels/rags without oil or grease on them! If you used the OEM flywheel then I suggest having it resurfaced like Clipse3GT said. That should be fairly cheap and quick. Then again, someone else had posted a month ago saying their mechanic said our style flywheel can not be resurfaced :dunno: I have my doubts about that though.

Our flywheels can be resurfaced. The only time it can't be resurfaced is when the thickness and thus strength of the clutch is compromised and the entire unit has to be replaced. I would just drop it all out, clean and inspect it. Hope for the best and make sure you tightened every bolt to proper torque specs. Not doing this can cause problems with the clutch engaging equally and will reduce the life of the clutch, as well might cause a potential hazard.
