    Over the past year I've had to keep filling the clutch master cyclinder reservoir as it kept loosing fluid (mineral oil). Finally got around to doing something about it. Ordered clutch slave o-rings from Zip-Ty Racing.

    Replacement was pretty straight-forward, removed the front sprocket cover and its mounting bracket to access the clutch slave. The o-ring on the clutch slave piston looked in ok condition, but the outer o-ring for the clutch slave assembly was damaged. Filled and bleed the system with new mineral oil. Hope this fixes the leak for awhile. Clutch Slave Removed.jpg Clutch Slave Piston - New O-Ring.jpg Clutch Slave Housing New O-Ring.jpg Old O-Rings.jpg

    M-Coupe99,
    Your 3rd picture shows the bare slave cylinder....the photo depicts a shiny spot on the right side of the slave cylinder wall.
    If the shiny spot is light from a camera flash...your cylinder might respond well to a new oring.
    If the shiny spot is bare aluminum & the grey coating has worn through from piston wear........I'm afraid your repair will not work.
    I have been down this road myself.
    Good luck!

    The shiny spot was from the camera flash, the cylinder wall looked uniform throughout. Hoping if nothing else it will slow the leak if it doesn't stop it completely.

    Good to hear the cyl. wall is looking good. Worth a shot to try a new oring then.
    Inexpensive repair.
    Uptite George used to sell a double seal x ring type replacement...not sure if these are available anymore.
    All the best,
