Brand New Clutch Slipping On R33

[Starionturbo]

hey guys

Last week I got a Xtreme HD cushioned button plate clutch installed on my skyline - my uncle fitted the clutch , machined the flywheel and I watched him do it, everything was good.

Drove the car for a few days, fine gripped well.

This afternoon driving it, went into second and put the power down and the revs just shot up. After a bit more driving, slippage in every gear. Drove it to my uncles workshop, he was busy, so had to drive home and the clutch got so bad, it was slipping off the line in 1st.

I am so dissapointed. Ive waited 2 months to get my car back on the road and have spent all my Money on this clutch + fitment and its not gripping.

To add to that, the XTREME distributer is not answering my calls/messages.

Any suggestions of what could be the problem. it shifts fine, theres a brand new master cylinder. Clutch pedal feels normal.

help appreciated

Regards

real crankshaft seal could be leaking(oil on clutch) but should have been changed with clutch.

checked that it was fine.

It could be a quite few things.

It sounds to me like there's a problem with the pressure plate possibly being faulty, or incorrect one supplied. Either that or the wrong clutch plate was supplied. There CAN be a whole bunch of other possible causes ( contamination, incorrect flywheel machine, pressure plate bolts not tight / broken, and so on ) but they are less likely to be the problem. Also worth checking is the clutch pedal adjustment to make sure you have freeplay.

After that, there's only one real way to find out !!

i had the same problem with my xtreem clutch but not as bad i just sent back to them and i was cause the presure plate was not strong enogh and i glased the clutch

Did you drive it sensibly for 500Km to let everything bed in ?

And do you have enough free travel at the top of the pedal ?

We have fitted and sold dozens of these things with no problem. However , that is not to say they may have made a boo boo .

There was not enough freeplay and apprently too much pressure in the hydraulic system.

All good now, clutch is biting hard!

How do you mean free travel?

I've been through 2 slave cylinders in my r32 gts.. I'm using a HD clutch from daiken.. wondering if that is what's chewing the slave's out..

I've been told to adjust the threaded rod behind the pedal.. if so, which way? and where should my takeup point be.. it's currently about 2-3 inches off the floor

Mine did the same thing. Bought the car with a dead clutch (really heavy single), replaced the clutch, fine for three weeks, then started slipping... then it got worse and worse till it was practically undriveable.

Shortened the rod on the slave cylinder, and it came good again. A month or so later now, and it's slipping in 3rd and 4th if I put the boot in.

I tried to adjust that pedal-rod, but it wouldn't budge! (removed split-pin and all) My mechanic thinks there's something else wrong though, because my pedal has about 3mm free play, then it's just stiff... all the way to the floor. Takeup seems to be right near the top of the pedal-motion.

I'm stuffed for ideas, and it sounds like my clutch has been nuked in the process. =-[

cool. not..

is the pedal heaps tight up the top??

ie. is there any freeplay.

because ive seen it heaps where the pedal isnt adjusted properly and the clutch mastercyl "pumps up" holding the clutch on abit..

you need to back the pushrod off abit to obtain a small amount of freeplay :lol:

[RANDY]

By "back it off"... it appears that rotating it will drive the rod into the master cylinder more, and thusly give the pedal some freeplay before it pushes on it. Is this what you mean? I'm quite keen to give this a try!

Any tips for doing this? I had a pair of multigrips on the gripped part of the rod, but it didn't want to turn. Do I need to remove the master cylinder first or anything? (or was it just the hyrdrolic pressure stopping me from winding it in?)

Cheers!

Put a flat edge across your flywheel, if its not level than thats the main cause of ur slippage

[RANDY]

Get it machined to a flat surface? I did get this done when I put the new clutch in. Looked dead flat too.

[shanef]

I thought mine was dead flat too. Sent it down to victoria to the supplier who i bought it off and turns out its not flat at all, this has caused the clutch to be fcuked so some1's up for a new clutch and the cost of the shipping, and it sure as hell aint me!

Howso? Was it curved ever so slightly that it was impossible to see with the human eye?
