    Slave clutch line Rust

    Did a spline lube and found this.Is this a common thing?I mean at 40k that seems kind of premature and $238 for a new hose.There has to be something cheaper and better then this.Any input is highly appreciated.2002 spline lube (17).JPG

    It ain't the miles, it's the years, man.

    If you'd like to scare yourself, consider that most of the rubber stuff is now measured on the Rockwell Hardness scale.

    Hopefully the tires are newer…

    This is the only rust on this bike and why there is what I like to know.I understand the rubber parts going south on something this old and all the brake lines are Spiegler because of it.Just weird.

    What is the actual part called so I can add a bit to the title. It really helps with a further search down the road.

    There's the kind of speckling on the fittings that's common with salty environments. Do you ride on the shoulder seasons when there're salt removal crud on the roads?

    Looks like the paint is starting to bubble on the surface adjacent to the fitting. I used to have that issue with my bikes when I lived back east and tried to ride year round.

    You are probably right about salt getting there.Who knows what the PO did with it.Out of curiosity I checked ebay and found used ones that look just like it rust and all.It is a mystery for me why are the other fittings in good shape.I found at good deal at MotoBins for a replacement,braided and all.

    Like. Good luck, man. I've had some decent luck with Frentubo stuff along with Spiegler. I put Spiegler on my airhead and it really helped on those ancient lines.

    I ran across this condition several years ago on my LT and I've heard others report it. I believe water travels from the forward end of the rubber sheath and gets trapped at the end with the metal fitting thus promoting the rust you see. I simply slid the the sheath up the line to expose the metal, cleaned up the rust and painted the fitting. I then placed a tie wrap at the forward end to hold the sheath in place leaving the fitting exposed.... no issues since. Alternatively you can cut the sheath away where needed if you can't slide it.

    So you are saying that the black hose is just a cover and underneath is a braided line?

    I’d spray some corrosion-X on all the metal parts to avoid this from happening again, even on the new line when it gets replaced.
    I see similar corrosion down here because of the salt air environment in S Florida but it isn’t nearly as bad as driving/riding through salty slush up north.
