I recently replaced the clutch in my R33 GTST skyline. The new clutch kit consists of an Xtreme pressure plate and heavy duty organic clutch plate. the flywheel is a Xtreme Cr-moly item and weighs 5.5Kg. the whole assy is smaller than the high performance Nismo clutch i pulled out. the diameter is the same as stock on the new one but isn't as deep. also got a new thrust bearing. the problem i'm having is while the engine is running i can't put the car in gear. the clutch isn't dis-engaging fullly. i was wondering if anyone out there has had this problem before. i've checked over the hydraulic side and found a faulty master cylinder. I replaced the master and slave cylinders. anyone have any ideas? i'm an apprentice mechanic so i know what i'm doing but this one has me stumped. HeLp!?!?!? thanks... I've also put calls in to various mechanics in NSW that work on skylines everyday and they think if it isn't a hydraulic issue the next thing is the thrust bearing carrier. does anyone have any sizes for the carriers as i've been told there are about 10 different ones

I had the same problem when i installed my clutch.

To fix it i just adjusted the clutch pedal, make it so it pushes the clutch in furthur.

(There will be a bolt you have to undo a bit, if you have a look under there you will see what is needed)

I tend to agree with the "various mechanics" - it's a problem of the wrong carrier.

You will need to pull the gearbox out anyway, then take measurements to work out which "height" carrier you need.

i was afraid of that... pulling the box back out. before that i think i might have to adjust the pedal a bit.. it feels good through the whole travel.. like from the top to the very bottom. its never felt that good. This is so crap guys!! a car like this wasn't built to sit in the rear carpark of a mechanics workshop while the owner figures out the problem.. ITS NOT RIGHT

can anyone tell me if this is a twin plate clutch? i've only every seen them in magazines and assembled.. this one seems to be sealed. as you can see from the pictures there are a few signs that it is indeed a twin plate clutch and if it is i may have solved the problem. so if you could take a few minutes to have a look at the photos and post a reply it would be greatly appreciated.. Excuse the pics.. they were taked with my mobile phone

Hey all... Sorry to steal the topic for a bit but ive been searching every where on how to adjust the clutch friction point, and have read few threads that all say do a search, i have a feeling those threads have been lost or deleted can any one give me a few hints how 2 adjust the clutch ? P.s is this link accurate ?

    • I had absolutely no symptoms whatsoever that anything was wrong.... I'm very happy it was all spotto'd and re-bled and re-torqued and aligned though. Will be picking it up tomorrow and undoubtedly be like "Oh, that clunk is gone" "Oh, the car really wants to drive straight" "Oh, that pedal feels better" "Oh, it feels like I've gained 25hp" "Oh, the handbrake works now" It should have been a sign that the new Project Mu shoes had 3mm of pad depth on them out of the box, and the OEM ones from 25 years ago that we took out also had 3mm of pad depth, implying the issue was not, and never was the shoes, but we put that down to it not being adjusted correctly. It wasn't, but it wasn't even adjustable at all given one side was boned and the T Junction of the cables was on a 45 degree angle, the non-working side being the one on the massive angle. Obviously when I had adjusted it and reset it and re-tensioned it I had either got it stuck or something along those lines. Oh well. Live and learn and absolutely could have been catastrophically worse so I'm rationalizing it as a win, kinda. I also got the chance to measure the distance between rear rim and the suspension arm/shocks and found a 30mm rubber block only just doesn't fit there. Which is great to know before ordering wheels, when I assumed 30mm was easy. The man with the Porsche adapters has rims that use 23.9mm of that space, so it's safe to assume I have between 23.9 and 29.9mm of space there to play with on the inside. The wheels looked pretty stupidly pokey with the 20mm spacers on the rear, only for me to find that the studs come out another 12mm and the wheel doesn't actually sit flush with the hub because you're supposed to cut your original studs. The wheels do have cutouts that kinda accomodate it, but not fully. So my 20mm spacer was anywhere between 25mm and 35mm. ~25mm and send it will determine on where the wheels sit with the spacers on. When I put the pads in for the track day I will mess around with spacers (with wheels that do not clear studs properly when mounted to spacers) and do more math, for the last time, for the 7th time.
    • Lucky pick up Best to find these things before something horrible happened to the yoke flange thingies I would hate to think what would happen if it dropped the tailshaft  Hopefully the holes are not flogged out in the yokes and it was just the bolts that got munted  As for the hand brake.....ouch, look like the disc got rather hot, and I assume smokey, I recall when I had a front caliper seize on the Commodore, there was lots of smoke and the disc was glowing cherry red when I was able to eventually stop and have a look, and stopping a big heavy car, going down a big hill with some rather high RPM down shifts and some hand brake action is something that makes you think hard about life
    • One of the things that never seemed right was the handbrake. Put in some nice new Project Mu shoes. We figured the rears were out, so why not. We're right there. My handbrake never worked well anyway. Well, this is them, 15km later. 67fdcf94-9763-4522-97a4-8f04b2ad0826.mp4 Keen eyes would note the difference in this picture too:   And this picture: Also, this was my Tailshaft bolts: 4ad3c7dd-51d0-4577-8e72-ba8bc82f6e87.mp4 It turns out my suspicions that one side of the handbrake cable was stretched all along were pretty accurate, as was my intuition that I didn't want to drop the tailshaft to swap them on jack stands and wasn't entirely sure about bolt torque. I have since bought the handbrake cables which have gone in. I'm very glad that I went to my mechanic friend who owns an alignment machine to get an alignment before the track day, because his eyes spotted these various levels of "WHAT THE f**k IS GOING ON HERE?". Turns out the alignment wasn't that bad, considering we changed the adjustable castor arms out for un-adjustable castor arms, and messed with the heights. Car drove pretty good with one side of the handbrake stuck on, unbleedable rear brakes, alignment screwy, and the tailshaft about to go flying and generally being a death trap waiting to happen! (I did have covid) (I maintain I adjusted the handbrake correctly, but movement caused shennanigans and/or I dislodged the spring on the problem side somewhat, or god knows what). G R E G G E D
    • Very interesting, im not sure how all those complications fit in to running a haltech instead of a stock ecu but I'm starting to think I'm a bit out of my league.
    • I just put 2 and 2 together. This is a Neo converted R32. The Neo ECU (in concert with the R34's AC controller) runs the AC quite differently to how the R32 ECU and AC controller do it. If you just drop it all in, it won't work. There is some tricky wiring required, including changing to the pressure switch that the Neo controllers want to see. I don't know what it is, because mine was done by a guru. It was a year or so after I did that transplant before he worked out what needed to be done.
