Anyone intrested in coming to help sort out my clutch?
 

Anyone intrested in coming to help sort out my clutch on a lazy Sunday, I'm currently in Forrest field at a diy workshop...

The problem I'm currently having is that the clutch is slipping while the car is idling, after having installed the new clutch and putting everything back together...

Its a 6 speed, the clutch and the flywheel are the right ones, I've triple checked, mounted the clutch up to the flywheel on the bench to make sure and to test it, worked and looked good on the bench... Only thing I can think of is that I stuffed up when I was tightening the pressure plate up and managed to not tighten it up enough...

Any help would be much appreciated and I can put on a few drinks for any one that Congress to help me work on it...

Did you torque everything up with a torque wrench?

What sort of flywheel, pressure plate and clutch plate are u using?

Bench test involves a proper clutch press. Lining up the dials and bolts doesn't mean it is the right clutch though.

Also, is the clutch master and slave bled up properly?

If u can check out the part numbers, remove the clutch kit and post some pics here or PM through, will gladly help ya.

On a brighter note, it is nothing to worry about. Will be something simple. Hope it can be sorted out soon.

Don't take it the wrong way but when you sum up all the time and money you wasted you could of booked the car at s technic or Evo R for a days swap and drive away hassle free.

Torque settings

Flywheel bolts should be 75nm and torque in a star pattern
Pressure plate to flywheel 16nm
Gearbox to block 50nm

just use a shifter man,, you'll be right.. ;)

My head hurts trying to read this dribble.

The clutch is an xtreme heavy duty pressure plate, the clutch plate is an organic heavy duty plate, its a single plate clutch, the flywheel is a standard Sti flywheel which the clutch is designed to fit...

The clutch kit part number is ksu24001-1a and WA bought from covs Osborne park...

I've never had this problem in the past, this time round its just been a nightmare...

The clutch master and slave were bleed properly

Every thing was torqued to the right specs using a torque wrench...

Is there any freeplay at the slave cylinder pushrod? If theres a hdraulic problem, ie; the fluid can't return or the pushrod/fork combination is wrong for some reason it could hold the clutch in the released position. Firstly, before you remove thew box again remove the slave cylinder. If the clutch still slips you have a fault internal. Chance you fitted the clutch plate in back to front maybe?

Checked there was no free play ect, tried a suggested still slipping, clutch plate seems to not be clamping with the pressure plate,

when I had it all together, when I pushed on the clutch it would release the pressure on the clutch plate, but when I released the clutch pedal the clutch plate was spinning not clamping properly...

But again with the slave removed it was doing the same...

I would sugest you remove the box again. Possibly the step on the flywheel is too high? or the spline in the clutch plate is wrong and slipping on the input shaft? It has to be internal, get it apart and critically inspect everything.

Is there any drive at all? ie; slips a bit or no drive at all whatsoever?

Have removed the box, clutch, and flywheel for inspection, it is definitely the clutch plate slipping

Yes i had drive in forward and reverse

It appears the diaphragm is warped, sometimes if the pressure plate is not tightened slowly and evenly side to side. Why are you using non genuine clutch cover bolts? Any chance they may be too long and bottoming out in the threads?

long shot, have you put the clutch fork pin backing( the big one that the clutch fork pivots on) is it in correctly ?

The non genuine bolts are a little bit shorter than the genuine ones, and the kit came with out bolts do had to get some from somewhere else...

Mounted up on the bench the clutch plate spins when I try turning it with a pair of stillsons using a dummy shaft

My only thought right now if that the diaphragm is warped too much to apply correct pressure to the clutch plate...

ok so I'm pretty sure the pressure plate is stuffed, going to try to get a new pressure plate tomorrow, and a mechanic is goin to give me a hand this time round... Wish me luck! For now watch the footy and drink jacks!

The flywheel could be faulty. We purchased one froma wreckers yard once that had been in a major frontal accident. (they didn't mention that) When it was machined prior to installation the centre hub was bent enough that it caused uneven clamping.

Can you measure the step height on the flywheel around all the mounting points to rule that out as well? Was the flywheel machined at all?

Didn't look like it had been machined, came off an 06 sti from japline, will measure it tomorrow, I'm pretty sure that I've got the right measurements written down somewhere,

14.7 mm step is the factory spec. 15mm is what most clutch manufacturers recomend.
It would pay to get it machined just to rule out any imperfections or warping.
Perth Brake Parts is my preferred contact for flywheel machining.

or imparts in osbourn park, they can machine flywheels too

Ended up getting a new exedy race clutch kit fitted it, all is good, drove back to Kalgoorlie last night no problems!

Good to hear, been a long process but next time should be easier for you.

Notice any difference in fuel cruising in 6th along Gt Hwy compare to the old 5 speed?

Yea should be much easier next time, I now know exactly which clutch fits perfect hahaha,

Only a marginal decrease but that went out the window with a bigger fuel pump and injectors with a tune...
