Installed new clutch disk and burned it up :(

[Turbo Monk3y]

Well i put in just a new clutch disk yesterday and put the tranny and everything back drove around with it for around 100 miles and now it slips worse than the previous clutch did good thing i only paid 45 bucks for the Oem replacement disk.. Anyways i guess i learned the hard way..... The only thing i can think of that keeps killing my clutch fast is either the flywheel or pressure plate friction surface.. When i installed the new clutch disk i noticed the pressure plate friction surface was kinda notchy meaning small imperfections it wasnt totally smooth all the way around.... And now my new clutch disk is smoked .. can anyone tell me what would smoke a clutch disk in 100 miles i didnt get on the car hard at all i drove it like a granny. My only guess would be not resurfacing the flywheel (which looked nice and smooth) or getting a new pressure plate and throw out bearing (pressure plate was kinda messed)... Im newbie to the clutch install i just did it myself cuz i was bored, but looks like i didnt know wat i was doing

first off, if you even drive fast one time a year you should have never put a stock clutch disk in, or left the stock pressure plate
second, you should of resurfaced the flywheel, you cannot tell if it is "good" or not by looking at it. It requires a tool to measure the step hight. Our flywheels are VERY touchy
third when you redo this your disk you just put in has been "glazed" it is probly not the best thing to put back in(not that it was even a good thing when it was brand new)
fourth, get a act 2600 if you want a real clutch

In response to the above negative post...

1) You don't always have to go with an act 2600.. I went with an OEM exedy clutch on my last clutch replacement.. It is still holding strong at 20k miles later..

But yes, You should always have your flywheel resurfaced and stepped. You can also reuse your pressure plate if it is not warped.. You will have to have that resurfaced and have pressure plate "stepped" according to how much was taken off of the pressure plate surface..

Those inperfections and pits were probably building up enough heat to glaze your clutch, which was making it slip so bad.

WHat does it mean steped flywheel, can any one explain it

 

[ArticNemesis]

Around the outside of your pressure plate you have 3 steps (areas that look like steps coming off of the main surface of the flywheel) That the pressure plate bolts up to and makes room for the clutch disk to fit between the plate and the flywheel. If this step is too small, then your clutch will engage all the time, and burn it up extremely quickly or it could be bad enough, that the clutch won't be able to disengage enough for the motor to turn over. If the step is too big, then the clutch will have problems gripping the flywheel, which will result in glazing the clutch disk, just like beating on a new clutch would do.

First, as the others above have pointed out: You should have resurfaced the flywheel. The step height has only gotten larger. Unless you have extreme mileage on the old clutch or had a more abrasive disk (3 puck) the height should not have changed enough to need resurfacing. You'd need to get it resurfaced it the surface was uneven, cracked, or heat damaged. However, it wouldn't have hurt to get it measured to be sure it is within spec. If the step height is too large, the pressure plate won't create enough force and the disk will slip.

Did you adjust the clutch pedal for correct engage/disengagement? ie. did you adjust the master cylinder push rod near the pedal? This would be a second cause of a burnt clutch.

you are wrong. stock pressure plate is fine its the disc that goes in it.

A feramic disc like the one AMS now sells uses a stock pressure plate and is good for 11 second passes ams has proven this. Its what i have on my car and it is the shit. I made 7 passes in 45 mintues all 60fts were 1.90 or below and i recently made 4 passes at the trake within an hour or so and all were 1.7x 60fts. THe clutch does not slip, no break in required and works great on a STOCK pressure plate.


But i do agree stock preesure plate AND stock disc is not smart.

Well since im back from thanksgiving vacation ive noticed this thread got bumped back up and for all of you who were worrying about my problem thanks but apparently all i needed to do was adjust my clutch pedal ... ive been driving on that new clutch disk now for 1600 miles mild racing and it holds and grips very well... there is no slippage.. All i did was replace the clutch disk thats it , i didnt resurface nothing, nor did i get a new pressure plate or friction surface..... so its all good now im just waiting for another break so i can install my lightened flywheel and act 2600 now

How do u get the right step, So when they resurface the flywheel they take the material of the whole flywheel even where the pressure plate mounts , Or how do they do it, thanks for all the help, Im trying to learn

 

[ArticNemesis]

5810. That is exactly what they do. They take of X amount from the flywheel itself then they take X off of the steps where the pressure plate mounts so that the distance between flywheel surface, and pressure plate mount surface are still the same as OEM spec.

Hey turbo monkey, i am curious what you did to adjust yoru clutch pedal. I am having a similar problem after changing out my clutch? But i did get the flywheel resurfaced and a new pressure plate, throwout bearing along with the friction plate. and now it is slipping almost as bad as before.

Are all dsm flyweels steped, because mine is all flat with 3 pins to align the pressure plate, The picture below is a awd flywheel (from vfaq.com)

Ok i installed my new clutch over this weekend ( oem type, i dont have enought performance for act), it grabs good no slip,but my clutch pedal is very soft. I thought that a new clutch kit would fix the softness.i also replaced the slave cylinder, didnt fix the softness.When i i checked pedal for freeplay i noticed that the masted cylinder is leaking (had fluid all over the pushrod and booth. Can that be the problem.

 

[ArticNemesis]

yes, replace / rebuild the master cylinder before it completely goes and leaves you stranded somewhere.. That leaking fluid would cause a pressure loss and make the pedal feel soft.

Thanks

I rebuild my master cylinder yesturday,It was a very simple job(Took about 30 mins)and only cost me 19.95+tax.: Fixed my leaking problem and my pedal softness. .
