jihwaan Posted June 16, 2011 Share Posted June 16, 2011 Ok so I had my mechanic install my exedy triple plate - sold disc centres - ceramatalic (what a lovely clutch to drive)- and of course its making the usual rattling noises at idle etc- no big deal. But under load when driving and when engine braking on decel you can hear this, well, rattle is the only word I can use to describe it but its more like a vibration rattle if you can get me- not there all the time just most times when under low load uphill, decel etc. Now I am not overly concerned coz the last clutch did this worse (and that was a twin disc sprung centres) - but my mechanic is. He says its bullshit and under load their should be no noise- I tried to explain I think its because there is no longer a dual mass flywheel to balance the drive line (its now a solid flywheel) the gear sets and all the other shit inside the box will rattle slightly with the harmonics of the engine at certain rpm / between certain rpm now that the dual mass flywheel is no longer in place to remove / reduce this - he isn't buying it (I don't know shit that is just what I have read and been told). He has been on the phone to Exedy Aust who say clutch shouldn't be making any noise under load/ normal driving- I agree and am saying its the rest of the gearbox that is rattling. Normally I wouldnt give a shit and drive it because I am happy with it but this is the best mechanic around by far, and I take his word on pretty much everything as he is a no bullshit if he doesnt know he will find out type of guy with decades experience. Any opinon's / idea's? I don't know shit and am not afraid to admit that- but it seems sensible to me an undampened driveline is gonna rattle... but when a man who you respect and trust his 40+ years experience says it aint right it really makes me wonder and think maybe i need to look into this...? (CW maybe...... lol I can only hope he stumbles past with an opinion...) Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted June 16, 2011 Share Posted June 16, 2011 I believe the adjustment of the converter is has to be spot on, otherwise it can cause slight disengagement and rattle, also have you by any chance changed the gearbox mounts for uprated? as this will cause vibration/noise to transmit through the body.

Chris Wilson Posted June 16, 2011 Share Posted June 16, 2011 The noise you hear is from the drivetrain, the gears and propshaft are now driven by an un-dampened flywheel and a solid centre clutch plate set up. Toyota fitted a dual mass flywheel and dampened clutch plate to combat this. It's normal, and you just have to live with it. Quote Link to comment Share on other sites More sharing options...
scoooby slayer Posted June 16, 2011 Share Posted June 16, 2011 dont worry about it, i have a brand new £2500 carbonetics tripple and a brand new £5000 6 speed toyota box and it makes noises all the time, nothing to worry about if its doing it from brand new.

It's normal, and you just have to live with it. ^^^ this is exactly what I thought I knew (and I bet I read it in one of your previous posts).. However I had to give the noise some credence as this mechanic really is the best there is around these parts... I like it when CW trolls through my threads and shares his knowledge. Chris you (and the other few guys - they know who they are- really contribute and make this forum such a good place to come and learn, and the fact you take the time for us and to answer our questions- guess I just wanna say thanks again. I don't get to drive my supra much, let alone get on the forums.... but when I do its usually with a problem and its great to have everyone's input- so thanks everyone for the replies!
