Clutch Noise Returns


Recommended Posts

Hey guys,

So a few months back I had a grinding metal on metal noise come from my clutch when pushing it to the floor.

Gearbox was pulled out, cleaned, thrust bearing replaced and the noise dissapeared until now! It's returned.

So the noise comes when pressing the clutch pedal to the floor. It's a metal on metal noise not the normal bearing noise from a thrust bearing. The noise happens when first driving the car and after heating it up and driving around for a while it stops.

Anther thing to note is you can feel the grinding in my gearstick when changing gears as well as in the foot pedal.

Ideas?

sounds pretty standard but when you say they pulled out the box did they take the casing off and inspect the internal bearings?

From my understand they told me they pulled the box out and changed the thrust bearing. They didn't change the spigot.. Is the spigot behind the casing?

What internal bearings are there?

Spigot is in the end of the crank..the input shaft sits inside it.

bearing on the input shaft, some in the rear part and in the center plate. I have pulled apart a few rb20 boxes that sounded similar to what you describe and they all had a failed bearing somewhere.. Pretty larbour intensive to fix so wont be cheap

Is it possible to do this work yourself or do you have to have a fair understanding in pulling a gearbox apart?

Like the other guys said replace the spigot first and see how you go, if you took it to a workshop complaining about the noise then they should have changed it while the box was out.

Guess I will be taking you up on the offer Mat to do it over a few drinks on a weekend.

Thanks for the info once again guys.

Workshop has since closed down so nothing I can do about it now.

i think we know why they closed down....

sorry to hear mani.

hope you get it sorted.

That will be the angle that you're pushing the pedal. Closer to, you're probably pushing more downward than when your seat is further away. The slight change in direction of force is changing the load on the pivot point, or conceivably the pedal spring.

    • I'll chime in here with my experience. Motec is great if you have the money and know a good person to support you. They don't really offer retail support and the dealers make SFA margin on the product, so the business model is setup for you to be supported by a dealer. I'm lucky enough to know a guy who's ex Motec and very generous with his time and is a total boffin. In addition to that, I also use Brad Sherriff who's an absolute legend to work with. The downside to Motec is the software isn't very intuitive, pay to play, poor/limited online support and costly upgrades.  I've not owned an Emtron myself but a good friend runs a performance workshop in Melbourne who is an Emtron dealer. They won't be fitting any more to customer cars because of the poor level of knowledge within the Emtron support team and lack of ability to solve issues with the platform. Not to mention the circumstances around the establishment of the product and company in the first place. I've run Motec's since the old M8's back in the early 2000's so I'm certainly not without a bias but I look at it like this. Everyone acknowledges Motec as the best consumer grade product without spending mega dollars on Bosch Motorsport / Life Racing and so on. When you consider the real cost of your car (not what you tell your mrs) the cost difference between an Emtron and a Motec is tiny, why would you compromise over a few hundred dollars?
    • Closer to getting the shit box back on the road. That long hose, took 2 months to acquire. However the rest were all already to go same week I ordered them. For those playing at home, that long hose is for a RB25DE N/A motor, as they don't run a water/oil heat exchanger, the hoses underneath the plenum are much more elegant and not a maze of shit.
    • One thing you may be able to leverage is the fact that the R34 N/A has the same setup as a S15. The S15 also is a car that gets 350Z diff swapped, so they will also likely have this problem. The caveat of course is it's possible the dash is different between the R34 NA and the S15, but the subframe/sensors/axles/diff setup are the same. I can't remember now as it's been too long, but I don't generally think people need to swap dashes between the N/A dash and the turbo dash when they do things like change the gearbox out, turbo their car, manual swap it, it's just not something I've seen mentioned so this could be compatible.
