Weird Sound Clutch Pressed In

[T-7ToNewOldB]

Brand new build, all new parts haven’t driven it yet.

WH clutch, AX15 trans.

When the clutch is pressed in it makes like a whirring sound. Like a fingernail lightly dragged on the edge of a base guitar string. I can’t see anything rubbing below on the return spring or the linkage.

Thoughts?

I have had the engine running (also new) but only with the trans in neutral. Only sound issue is engaging and disengaging the clutch.

Throw out bearing new?

Hi, X2 the noise could be in the throw out bearing. Sometimes you can feel that in the clutch pedal. Probably not a pilot bushing but are you sure there is a pilot bushing in the crank? Good luck

X3 on TOB. Probably not going to be a problem.

Bearing was my first thought too

New TOB. Basically all new and by basically I mean it’s all new. Very muted sound like a thrumming. Plastic rod running down the side of a spring or something.

All new and doesn’t sound major so I’m going to ignore it for now but definitely chewing at me. Pilot bearing is also new. Whole truck is, father and son build. But my son has a new girlfriend so this is more a father and beer truck right now.

Good point. So far only drove it out of the garage and back in. Did that great.

Sadly also noticed that I flipped my flex lines from the proportioning valve on the master for front and rear. Need to fix that. . .
