So i noticed if the clutch is getting hot i get a strong vibration in the clutch as i let it out. I sounds and feels like its grinding a gear....but it does it when a gear isn't even engaged???? what the hell is going on here?

If i press in the clutch all the way its okay, but once i hit the point where it would normally grab if it was in fact in a gear it starts grinding? If i let it out all the way it stops the noise.


suggestions?

ive seen this before in a car when they put the clutch plate in back the front but since yours has been in for a while id be guessing its either worn out and your getting metal clutch pad rivets scratching your flywheel or maybe youve lost or are in the process of a broken or dislodged clutch plate spring.Just a guess, when you pulling it out?

Dont know. I don't have any place to pull it here at school. The clutch holds fine and doesnt slip at all. The vibration only happens if it heats up.

Example: on a steep hill and need to let the clutch out slowly so you dont stall, depending how long i need to burn up the clutch thats when the vibration will start to take place. It goes away in a few minutes of cooling down.

Are you sure that what you are feeling isn't clutch chatter or shudder?
It will feel like an uneven and un-smooth engagement.

correct me if im wrong but clutch chatter to me is more choppy engagement accompanied by vibrations, like a shuttering as if you let the clutch out too quick. This is a straight grinding noise accompanied by vibration even if the gear is NOT engaged remember

So are you saying if in neutral and you press and release the clutch, you get a straight grinding noise?

If so, I would lean more towards your problem residing with the clutch and/or transmission, with the clutch components being the first place I would start probing.

touche,
the grinding wouldnt be a symptom of clutch chatter.

the only other thing i can thing of is that the clutch is not disengaging all the way...
