Clutch noise with pedal out/brand new!

That doesn’t sound very good. So go back and bite the bullet?

Hi there,
I'm pretty sure it's only when in N.

Therefore, if in gear and clutch out it will be doing exactly the same thing as the clutch is in the same position., again with no load on it.
The reason ANY release bearing rattles is because it pivots only on one axis in its holder AND the uneven fingers of the clutch diaphram spring hits it back and forward on its axis as the engine rotates the flywheel. My Cruiser did it slightly and ensuring the clutch fork withdrew the release bearing slightly more than just sitting against diaphram spring fingers meant NO rattle. It isn't a faulty bearing but poor clutch plate friction material thickness, ie, variation in thickness which causes it to happen. If ALL clutch fingers are in same plane then NO possibility of flicking the release bearing exists. Bearing good! Clutch BAD!

The bloke who fitted the clutch simply threw the plate in and bolted the pressure plate over it and didn't look at finger height at all or doesn't know to look. Some slight spot sanding of clutch plate can improve it. Other reason is, the pressure plate is bolted on but has something under the edge , ie crap, OR, the pressure plate is simply not accurate enough. Because of the leverage ratio of diaphram spring fingers. inner to outer edge any slight differences in components can create the fault.
