How a motorcycle clutch works ?
This is the right side of the engine, removed the cover to expose the clutch on the side and we're moving now the last one of the four clutch springs when I remove this cover and now take apart the clutch plates as you'll see this one has a teeth on the outside and it hooks up to the outside of the clutch .
This one has the teeth on the inside and it hooks up to the inside of the clutch like to demonstrate to you quickly but it looks like when the inside part of the clutch and the outside part of the clutch are not moving together that's what we have here if I take this first clutch fit off you'll see we have the plates with the teeth on the inside rotating and rubbing against the plates with the teeth on the outside, so what is happening is that the two want to rotate together but because one is not in the same and not rotating at the same speed .
They are creating friction eventually with the force of friction the two will rotate together like so and this can happen vice versa as well if for example the crankshaft is spinning but the rear but the inside part of the clutch is in place then we have this and if you can see on the other side the sprocket at this point is not moving up until the two are able to rotate together at the same speed the crankshaft through these .
Sprockets turns the outside part of the clutch so the outside part of the clutch is what is linked to the to the movement of the piston and the inside of the clutch is what is linked to the sprocket through the transmission and here is how here is where the two of them become synchronized is that when we when we let go of the clutch we are allowing these plates to rub on each other and eventually through friction to turn at the same speed as the clutch reassembled.
Now I'm going to demonstrate to you what it would look like if we were pulling on the clutch lever on the left side of the handlebar this is where the cable so that clutch lever lever is attached to normally when I pull on it to see the clutch clever separates the me zoom in so you can get better look at that I'm pulling on it even though it's a very small noticeable difference as you can see here I'm pulling on it and I let go pulling on it let go so the clutch clever moves away from moves away .
Fishing up against the clutch springs thereby reducing the friction between the clutch plates let me demonstrate this pulling let go pulling let go when we pull the lever on the left side of the handlebar we're pulling on the clutch and the cable that is attached to that lever yeah at the other end of it is attached to here on the top of the engine now let me explain what that does it is held in place by this screw just which I've already loosened and it has a spring on it which is how this thing comes back to its position back here when we pull the clutch lever it's actually moving forward like this and what this does let me pull it out for you see .
If you see here at the bottom of that rod has that shape so when we pull the lever it turns like so and the effect of this is let me get back to the other side to explain that to you it's moving a rod there's a Rotter that touches that pushes up against the bottom of this stick about here and what it does with that is it pushes that rod to the right the right side of the engine explain that to the other side if we follow the rod that the other end of the clutch cable is attached to as you can see it's actually coming up to the other end of the shaft and way it's touching on is this rod.
This rod sits inside here all the way to the other side and on the other end of it is this ball which is there to reduce friction and the clutch club is clutch cover sits inside of that shaft and so when we pull the clutch lever pushing this rod out towards us what it does is it pushes away the clutch cover and that is how we get the reduction in friction between the clutch plates because this clutch cover.
It's mounted onto the clutch with these clutch springs and those clutch springs are what increase the friction between the plates so by pushing those so by pushing the clutch cover out we are allowing more space between the clutch plates and that reduces the amount of friction.
