Hi guys,

i just fitted a new H/D clutch and changed my gearbox oil (Redline). However, i noticed that my gearbox sounds pretty loud. It's the grinding sound that i know you normally hear but i feel that mine is exceptionally loud!

The clutch sounds loud as well when i release the clutch to neutral, only when i 'clutch in' then the sound goes away.

Is anyone going through the same situation as i am or it's pretty much normal or i can do something to decrease the noise besides increasing the volume of my stereo?

was it just a heavy clutch or a twin plate. if it is a twin plate, then they always make noise. if it was just a heavy single then the noise is most likely a noisey input bearing. i have the sound noise and thats what i got it diagnosed as.

What type of noise is it.. rumbling?.. whining??..

Sounds like it's probably on the input shaft bearing if it's when clutch is out in neutral..

Mines currently got a similar issue, however 20x worse.. sounds like i've got straight cut gears..

Ive got a little bit of a grinding noise on loading at low revs any ideas...

oops hijack

Yes links it's the whining noise. Sometimes u can hear it when u release the throttle. How bad is yours?

Is there any way at all to fix it?

Have had the same noise for 3 years now since i got the Xtreme clutch put in. You get use to it after a while and since the exhaust i dont hear it that often. Clutch is still strong though. Ive heard it on a few aftermarket clutches.

Yeah the clutch is fine. It's a normal single plate H/D clutch. I got a feeling it's the gear box? The input shaft as what you guys said might be the problem. Is there anywhere to fix it? How much will it cost?

Anyone at all? Could it be there isn't enough gearbox oil in the gearbox?

No mate you'll be allright, I have the same problem and most of the people I know it is a bit annoying but you get use to it i suppose.

It can go for years apparently until it finally dies on you, and if you are smart you would have saved some money and get an RB25 second hand gearbox put in. apparently they are tougher than RB20's.

Cheers

Sorry for the late reply..

Mine is really loud on acceleration/deceleration.. so whenever you put load on it really..

You could look at recoing the gearbox.. no point replacing an input shaft bearing and that's it as they need to remove the front bell housing off..

$400 labour to pull it down..

$300 labour to reco gearbox

+ parts..

2nd hand R33 gearbox - try $1400 in unknown state.. so see how annoying it is..

Than again.. with these things you never know what it could be.. maybe goto a gearbox specialist and get a recommendation..

With the clutch in.. e.g. foot on pedal.. and free revving it - can you hear it??..

Also - in 1st/2nd.. rolling down a hill with the clutch in.. can you hear it??..

I don't drive an r 32, i've got a 34 but i don't think a 33 gear box can fit into a 34?

Links, PM sent

No it can't.. so if it's really bugging you look at reco'in it..

I also have a rattling on my clutch pedal on top of that noise. Does any of you have those rattling feel as well?

Links if you are looking for a clutch, i've got a friend who works in Exedy and they can get real good prices.

Well.. I would.. but my one got replaced about 300kms ago..

I've got a rattling/squeaking thrust bearing as well.. but it appears to be going away as it maybe grooves in or something.. not sure what the hell is up..

does the rattling go away when you depress the clutch pedal??
