Arhhhh ok So when you pull the clutch in. Let me try to explain some thing.
The clutch consists of 3 main pieces, The fly wheel, The centre piece of the flywheel that has the 3 prongs, and the pressure plate.
When the motor is running the outside of the flywheel is always spinning. No matter if the clutch is in or out. When the clutch is engaged every thing spins. The pressure plate has the three holes in the centre of it that fit over the three pins that stick out from the centre piece of the flywheel. The centre piece of the flywheel has small ball bearings that separates it from the outside of the main flywheel. When you pull the clutch in the pressure plate moves outwards away from the out side of the flywheel. So now that the pressure plate is disengaged from what was driving it, It is still and the centre piece of the flywheel is also still. The ball bearings that separate the outside flywheel from the centre flywheel NOW come into action. The only time these ball bearings come into action is when you pull the clutch in.
So it must be these that are squeaking.
Anyway English was one of my worse subjects so most if not all of this made no sense. I will post some pics for you they might be of some help.
There is no pressure plate in these pics. These are pics of when removing the flywheel and the centre shaft of the clutch.
