Throwout Bearing?

[RicsR33]

Hi Guys

Last night i gave my R33 A quick and hard gear change from 1st-2nd causing the car to step out a tinybit but once i got home when the car was idleing in my garage i could hear a small funny noise then I put my foot on the clutch and the noise go's away. foot off the clutch comes back.. did i damage my Throw out bearing or is this normalish for Skylines??

thanks

Sounds like you have a main shaft bearing noise there, when you push the clutch in the main shaft is not turning so the noise stops .

the thrust bearing noise would be when you put load on it ( that is clutch pushed in ) .

Is this something to be concerned about? i wasnt hoping to touch my G/B for a little while..

That depends on how loud it is. I think you will find out the noise was there before....

Yer it really isnt that noticable at all, you can hear a slight change in the engine tone very slighty..

My clutch makes a little 'whirring' noise when I haven't got my foot on it. My mechanic says it's normal. You could ask a (trusted) mechanic to have a listen and see what he thinks.

your clutch can not have a noise if your foot is not on the pedal, its spinning as an entire assembly locked up to the flywheel and front of the gearbox assembly.

wrxhoon is 100% correct on theory of operation and diagnosis.

if its only there when the pedal is not pressed in, its either normal noise from the gearbox (they all make a bit), or the input shaft bearing is worn/noisy or its the gears on the input and cluster gears have the hard casing worn off the teeth and thus causing excessive noise.

not worth worrying about really if you know you have the correct oil and amount in the box, all you can do is add some nulon g70 gearbox/diff additive to quiten it down a little bit.

and to add to this Bearings have a grumble not a whine , also the gears dont always wear the can stretch and flaten out and this also causes a niose .. Its extremly common on all gtr all the ones i have ever driver have made it lol
