When my clutch is out somethging is making a whining noise, but when clutch is in I think the whining noise goes away.

But when I put the clutch in when in neutral I get a rolling, tapping noise. I only ever get this noise in neutral

Anyone got any ideas, the whining noise is starting to shit me.

I think that the sound that you are hearing is from the clutch bearing. When you have the clutch in neutral the fingers of the clutch might be just scraping on the bearing. And when u push the clutch in, it (bearing) engages with the fingers n stops slipping on them.

I have a similar problem in my subaru. I put a new clutch in but i think i stuffed up by not putting enough grease on things. The clutch bearing seems to be still touching the fingers of the clutch when i have the car in neutral. I can;t seem to change it cos if i losen off the clutch cable i can't get enough throw to disengage it.

Don't take this as gospel. It is just my ideas.

Yep sounds like gearbox input shaft bearing, Unfortunately its a common problem in the skyline boxes.

Best way to diagnose is park car in shed/ garage, start car, gearbox in neautral and listen for

Grumbling bearing noise (sometimes whirring) Then press the clutch pedal in. If noise goes away it indicates the Input shaft bearing in the gearbox, if Noise still there its the throw-out bearing of the clutch. Hope this helps, Have found redline Shockproof oil works wonders in these boxes to. Should change gearbox oil at least every 40 000km.

It happen to mine about 10 months ago. A throw out bearing. The gearbox guy said it does no harm you just have to put up with the noise, to fix it is a major rebuild. He put some redline oil in it and told me to come back when the box shits itself from somthing else, away i went. And yeah the redline oil does not stop the noise, just better gear changes. :D

Hey I just started to have this happen to me, can anyone confirm this needs a major gearbox rebuild? How much damage is it doing? (Getting kind of paranoid cause of the GOR cruise in 2 freaking days)

I'm sure mine is the input shaft bearing too. Started making noise after a spirited drive, hilly stuff.

It only got rebuilt last year with new stuff, but it is take 2x stock HP.

Still annoying that it happened. Hasn't seemed to get worse though and doesn't make noise when coasting along or deccelerating, or when pushing in clutch sitting still.

in my experience its gonna be different for every gearbox i pulled mine apart recently and the counter shaft bearing in the carrier plate was farked but input shaft bearing was ok.

i had the same problems as everyone else though, mine just got really really loud so i swapped it

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
