Getting familiar with the clutch workings...

[JoeH]

My clutch stopped working properly - pulling the lever in didn't disengage the clutch.

Now I pulled the cover off down by the front sprocket and had a look at the clutch piston and pulling the clutch lever moved it by 2mm at most. I'm assuming that this isn't enough to operate the clutch properly?

I'm guessing there is some air in the system as along with the minimal movement the lever action had very little resistance. Any ideas how air might have got in the system in the first place?

Also the bearing behind the cover looked like it was covered in the clutch fluid (brake fluid?), is this normal?

I'm thinking of reverse bleeding the system by pumping it through the bleed nipple, good idea?

Sorry for the multiple questions, as you can see I'm new to this.

Many thanks

2mm is probably enough to disengage plates. never measured the movement, but it's not much..

air gets into system usually by having low fluid level in reservoir.

reverse bleed works.

bearing behind clutch slave should be covered by trans fluid. clutch slave has a seal that may have failed...

go to ajpamerica, they have a really good video on back bleeding. just a thought, could it be a seal on the master cylinder piston? i would think that that would do it. or if the adjustment screw on the lever (the one on the actual pump) is in too far, it wont let new fluid from the reservoir into the line. just thoughts for you to think over.
