Grinding noise when clutch is fully pressed

[dd4321]

Hi guys. Just wondering if you know why my R33 is making grinding noise when the clutch is fully pressed. This occurs especially in the morning or whenever the engine is cold. I can feel the vibration through the gearknob. But once the car is warm enough, ie, after 2-5 mins, the noise disappear. Spoke to a mechanic and was told that it could be the springs aroundthe clutch are worn and should not cause any problem as long as the clutch is still biting. The clutch still feels very tight & biting,.

Any idea? I just bought the car last month, so I don't know the service history.

Any help is appreciated

Thanks

Grinding noise when clutch is in sounds like the throwout bearing. I've never heard them grind though - just a horrible squeal - but a grind could be the bearings packing it in.

You'll have to get it looked at though as it doesn't sound right.

Spigit Bush I think???. Not really a prob, just change it when your clutch f*cks out.

i occasionally get a weird grinding/ whirring noise after selecting reverse with the clutch pedal in (disengaged), it stops once i the clutch is engaged. has done a few times after installation and appears to be lessening but i can never make it do it on demand, seems strange for an otherwise quiet and well operating gearbox

Mine was doing the same thing last winter but has gone away for awhile.

Since the weather has warmed up it hasnt been an issue. Im pretty sure its the throw-out bearing also.

As long as the clutch still works ok you will be fine for awhile, you will know if it ceases up

As said previously its more then likely the throwout bearing. Not a huge problem.

I'd say it's the spiggot bush and the reason i'd say this is that I noticed on the weekend that my car made this noise about 10x (when clutch is in selecting a car, noise stops when clutch pedal is released) and I had the exact same noise/feeling about 2yrs ago and it was the spiggot bush that I got replaced (with a new clutch at the same time).

From memory its like a $15 part but requires a day of labour to get the gearbox in/out and not much more time to swap over a new clutch. The noise is extremely irritating/embarressing though, pity it costs so much to fix such a cheap part.

I was under the impression the the spigot bush or bearing was always spinning whether clutch is engaged or disengaged. It should be something like your carrier bearing (throwout). Don't let people fool you coz if you smash one of these and you are behind someone at the lights, bang...clutch engages and you go flying into the person in front. Dunno bout you but that seems fairly serious to me.

Spigot bush or bearing is only a few dollars. Labour on remove and refit G/box should only be around $300. That's not being friendly either. Some will be cheaper. You should preplace the clutch while doing any of this work unless the plate is 6 months old or less.

im having the same problem, but it only happens when im boosting.

So, if i was to get a new clutch im looking at 15 for new Spigot Bush, 300 for labour and the price of a new clutch hmmm

it could be the springs on the clutch rattling.
