Brand New Clutch Slipping On R33

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

Kim

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 !!

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 .

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:

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!

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!

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
