leet8845 Posted September 1, 2014 Share Posted September 1, 2014 I went for a long drive again today and the noise is back. I recorded it with my webcam but the sound doesn't pick up that well although you can hear it a bit, it's louder when you're next to it. It sounds like something rattling when the clutch is not pressed in. My fans goes off after 1 minute, 7 seconds and you can hear it a bit better Any ideas what it is?

ZMANALEX Posted September 1, 2014 Share Posted September 1, 2014 May be the gearbox front bearing. Go talk to your garage that fitted the clutch. Alex. Quote Link to comment Share on other sites More sharing options...
leet8845 Posted September 1, 2014 Author Share Posted September 1, 2014 Yeah, I got it booked in on wednesday. I know for sure it weren't happening before so it must be one of the new parts or something incorrectly fitted. Quote Link to comment Share on other sites More sharing options...
OllyB Posted September 1, 2014 Share Posted September 1, 2014 Is it a lightened flywheel? Mine sounds a bit like that below 2000rpm Quote Link to comment Share on other sites More sharing options...
leet8845 Posted September 1, 2014 Author Share Posted September 1, 2014 No it was a LUK flywheel. Does your flywheel always sound like that? Since having my parts fitted (clutch, flywheel, slave, clutch line) this is what happens: Difference in idle sound when clutch is not pressed down when engine is cold. A ‘whirling’ sound can be heard which goes away when you press the clutch. Sound gets progressively gets louder as the car is warmed up to the point where it develops into a sort of rattle. The sound will subside as the car cools. Whenever you turn the engine off, the rattle occurs, quite loud. If you press the clutch the turn the car off, whatever it is, no longer rattles.

OllyB Posted September 1, 2014 Share Posted September 1, 2014 Oh, that shouldn't make more noise than standard then. Take it back to whoever fitted it..... Quote Link to comment Share on other sites More sharing options...
leet8845 Posted September 3, 2014 Author Share Posted September 3, 2014 I've took it back and they have said it's the gearbox making the noise, it's nothing to worry about. I'm not sure if it was that loud before after a long journey. I've managed to find a gearbox off a 08 reg with 18k for a good price. They said they would fit it for £100 as a goodwill gesture. I think I'll do it as isn't this an improved gearbox? Quote Link to comment Share on other sites More sharing options...

alexdax Posted September 3, 2014 Share Posted September 3, 2014 sometimes my Z makes a noise from the gearbox, usualiy in the first statup of the day. this noise is there from the first day and the Nissans guy (engineer) told me that is was a "normal" noise because the first models have a defective bearing in the primary-shaft gear box. he tell me that it wouldn't go bad, the noise would be the only thing i will notice but we will replace it if i decided so. i didn't want my new car with an open gear box, so i didint do nothing, my noise is there from the beginning but nothing bad happen...

leet8845 Posted September 3, 2014 Author Share Posted September 3, 2014 (edited) It depends... What year zed is yours? There are differences it's an 04 (06/04)Do you know if it will fit? I only thought it would because according to this article it will but he is selling the box: http://www.z1motorsp...roducts_id=3342 Edited September 3, 2014 by leet8845 Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted September 3, 2014 Share Posted September 3, 2014 Refer to my previous message above #2. This is a common gearbox noise, just live with it as I doubt it will get any worse. You may be experiencing this noise now as perhaps they have put the wrong oil in the gearbox which unfortunately is also a common issue. Alex.

leet8845 Posted September 3, 2014 Author Share Posted September 3, 2014 Thanks, I did supply the correct oil and the changes have improved. It was hard to get into 1st when cold but now it slides in fine. Does anyone know, would a 08 manual gearbox fit my 04 reg manual if I did ever need a new gearbox?

leet8845 Posted September 3, 2014 Author Share Posted September 3, 2014 Thanks for the info. Would this one fit straight on?: http://www.z1motorsports.com/350_g35/product_info.php?cPath=506_569_581&products_id=3342 Quote Link to comment Share on other sites More sharing options...
Azure350z Posted September 3, 2014 Share Posted September 3, 2014 Yes, the CD009 gearbox in your link will fit your 04 Zed. Remember there will be shipping costs and import duties to pay on top of the sale price though. Quote Link to comment Share on other sites More sharing options...
leet8845 Posted September 3, 2014 Author Share Posted September 3, 2014 Thanks. At least I know that's an option. I've ordered quite a bit of stuff from the US, there's a site that will work it out for you customs fees etc. It's £2500 for the same part in the UK so still might work out quite a bit cheaper. My gearbox is ok now though, the noise hasn't got worse and I can only hear it on my quiet drive with the wall right next to it. I can live with it providing it's just a noisy gearbox and not my new clutch fitted wrong. I guess time will tell. Quote Link to comment Share on other sites More sharing options...
