Hi all

I have a TS2CD OS giken twin plate clutch in my skyline, and was wondering if anyone out there using a OS giken twin has a vibration from 1000-2000rpm, not there at very light loads, but otherwise it is?

I just want to know if I can cancel it out and start looking at uni's/centre bearings etc (because I heard twin plates rattle somewhat)

Thanks lads

they only rattle when your foot is on the clutch (that is the sandwhich plates rattle in the carrier).

I've had 2 OS clutches in the GTR. first an OS triple plate, and now and OS twin and neither did what you are describing. that's not to say it's not the clutch, but it's certainly not meant to be like that.

No vibrations in my OSG twin plate.

Mine rattles when the gearbox is in neutral and there is no pressure on the pedal. As soon as I touch the clutch pedal, the pressure plate has load and the intermediate plate stops rattling. Obviously in gear and clutch up, it doesn’t rattle either as there is plenty of load on the intermediate plate.

:D cheers :wub:

:( cheers ;)

really? is that a push type? cause mine is silent when there is no pressure on the pedal in neutral. as soon as i put my foot on the pedal (disengaging the clutch) the intermediate plates (it's a triple) start rattling. It's the same with the new twin plate. foot on the clutch = plates rattle in the carrier. no foot on clutch = no rattle.

As does mine, yet Snowman's Jim Berry rattles the way SK describes it. Baffled me too when I heard it.

yeah the two nismo twins i've heard in R34 and R33 GTRs were both the oposite. they were noisy when off the peddle, quiet when on the pedal. so i would say it's to do with the pull type clutch vs the 32s push type.

I think maybe SK got it around the wrong way??

No I haven't, I very quickly got sick of people walking up to me when it was idling in neutral and telling me to turn my engine off because of the big end rattle. I make them go away by pushing the clutch in and the rattling promptly stops.

:nyaanyaa: cheers :laugh:

I'm guessing you are talking about Kris's and Nick's cars? They are using coppermix clutches which have a different setup to most twin plates. Both clutch plates drive a single hub. They rattle less than the normal types on idle, but they do rattle a bit under light load.

Yeah i actually have this problem. I remember reading somewhere on this site of other skylines with similar problems. I can't remember what the fix was but i don't think this problem was directly related to the clutch. Although maybe it is.

      Red Line 75W90NS in rear diff R34 GTT

      Great to know! The guys from The Skyline Shed are going to sort it out and send what I ordered anyway. Turns out their supplier sent them the wrong stock.  But it's good to know I "can" put this in if needed

      You do not need an LSD oil in any stock (non-GTR) diff, even if it is an "LSD". This because none of the (non-GTR) LSDs are clutch/friction type LSDs. Either viscous or helical - neither of which require an LSD oil.

      Hi everyone, I bought the Redline diff oil and the seller has sent me Redline 75W90NS even though that’s not what’s pictured.  I’ve already booked a hoist to go and change my diff tomorrow but I’m not sure if the NS is ok for the rear diff in a R34 GTT I think the NS does not have any slip modifiers so would that be an issue?    thanks in advance

      Not easy to find pics from 15 years ago, but here is a partial one. Keep in mind that it curved immediately from the airbox, then kept a straight line for the MAF to read correctly, followed by a 45 degree bend straight down to the turbo. This connection was the most difficult as it had to twist as well as bend to meet the almost vertical straight section of the intake.

      Yes, well, wrt a wheel alignment, there are two types. Either: You have very little added adjustables, in which case the alignment can be done by anyone in any tyre shop or equivalent, and will only take 30 minutes, and so there is no reason to even consider leaving the car there. OR: The alignment is a major exercise because you have adjustables everywhere and so you will need to be taking it to a shop that is skilled and experienced at setting up race cars and the like, and you won't need to worry about leaving the car there.
