okay this is kinda general question and not meant for my car but i;m havin a bit trouble understand how the pressure plate release the clutch.. don't tell me to search or google or even go to howstuffworks because i did it all spent 2 day.. this is a clutch from a car at work.. i;'m still wet behind the ears

1. now the rotor looking this is the PP disk to the left of it is the cover. now look a little bit up. u see an arm with a pin.. what is that called anywats how does that work.. does that flexes so when you press the fingers it moves the cover back(since the cover is connected to the disk with that pin) and so that the pin flexs it moves the disc away from the clutch?


2. or the fingers are built into the pressure plate disk ad when u press on it it pushes just the disk back. but inorder for the disk to push back the cover has to be moved out some it can accomdate the space needed to pull the disk away from clutch thats why i think number 1 is right.

 

bump

 

up and up and up..

 

If you look just inside the friction surface of the plate, there's a series of rivets around there. When you press on the fingers, just imagine those rivets being a pivot point. So in that picture, here's how you can think of it...

Throw-out bearing presses on the fingers, pushing towards the camera (in that view).

Spring-like material (what the fingers are made of) pivots around those rivets.

Outside of those rivets, it pulls the friction pad away from the camera, disengaging the clutch.

Does that help make sense of it?

 

so the cover of PP doesn't move so basicially between the PP and friction disk there is a gap between them to because it looks very close together.. also when the TO bearing reaches the pp it spins right

what makes it make the screeching noise when u try to engage the clutch?

 

The cover of the PP is bolted down to the flywheel, and the friction surface of the PP is spring-loaded, clamping the friction disk tightly. In that normal state, the clutch is engaged, meaning the crankshaft and tranny shaft are connected together.

When you press the TO bearing it flexes the fingers in (towards the camera in that picture). That pulls the friction surface of the PP away from the clutch disk (slightly) releasing the cutch disk. That releases the tranny shaft from the crankshaft, meaning that disengages the clutch.

Every car I've worked on has some weak spring holding the TO bearing lightly against the fingers of the PP. (Honda's spring is inside the slave cylinder.) That way the action of the pedal is consistant as the clutch disk wears down. Also, that means the TO bearing is always spinning.

(remember, you press the pedal down to DISengage or release the clutch)
Bad TO bearing?
Gouged-up surfaces on clutch, PP, or flywheel?
Bad tranny shaft bearing?

 

now that confused me.. i thought the shaft is always connected to the flywheel? i don't think the input shafyt on the tranny moves in and out...unless some cars are different.. becaust the shaft goes inside the crankshaft.. and the whole tranny is bolted to the engine block.. unless the shaft moves when u press the clutch in...

Otherwise you couldn't stop without stalling the engine.

I think you need to try this again...
