Clutch Lever Hard As A Rock

Discussion in 'Technical Help' started by johnny, Nov 23, 2020.

  1. Rebuilding LH side of the bike and replaced Clutch Slave. Lever hard as a rock. Replaced spare slave and no pressure. Bled a bit and lever is hard again. Clutch does not move. I did accidently squeeze the clutch lever when the slave was off earlier so thinking this may be the issue.

    What do you think, bleed the primary at the lever?
     
  2. You could try it, is the piston properly pushed back inside the slave cylinder? Is the clutch assembled properly and can the pressure plate move against the springs?

  3. If you detach the slave from the bike and gently squeeze the lever does the piston move? Push the piston back home and try again, does the piston move freely? If so then look at the pushrod & pressure plate is there an issue eith them? Did you do anything with them or is it just the slave you fiddled with?

  4. Thanks Both, My brain must be parked at the moment. Slipping off the slave and checking movement is so obvious ! Yep tried it and no movement on the piston. Must be main reservoir piston
     
  5. You'd have to check the slave cylinder by manually putting some pressure on the slave cylinder to push the piston back in before checking lever movement.
    Otherwise the hydraulics will self-fill the slave causing the piston to be hard up against the inside of the slave. If that happens your clutch lever would go solid.

  6. Nothing is moving Turbo. So push against the pistion? I swapped the slave and it was the same result
     
  7. When the slave is installed in the bike, the resting position is for the piston to be pushed into the body of the slave by the clutch pushrod. If you connect the hydraulics up with the slave "free" (not fixed to the engine with pushrod in place and clutch assembled properly) the lever will appear rock hard as there's nowhere for the piston to go.

    What components were disturbed on the RH side of the bike, and have you got all of the clutch components back in properly?
     
  8. like the piston in the slave has bottomed out. push rod to short?
    any chance the banjo bolt is incorect?

  9. Is it an aftermarket slave? Some of these require a spacer inserting into the small bore of the piston, if this is missing lever would be solid.
     
  10. It is an aftermarket but I have the origina and that did it too. This evening I got the lever better but now it is too loose ! I shall try and bleed it latter.
