Rust zone issue on lower end of hydraulic clutch hose
Posted: Sat Apr 11, 2015 9:22 am
In the midst of replacing clutch on an '04 R1150R, if you've gotten into the bottom of the motor you know the time involved in working through the layers of parts to get to said clutch.
The protective sheathing/cover on the hydraulic clutch hose is the problem by holding water and not drying out down on the clutch slave cylinder end of the hose. Water gets into the sheathing/cover up by the forks and seeps down and sits on the lower hose connecting point to the banjo fitting which connects to the slave cylinder. I live in Iowa City and stored the moto last November '14, when removing the slave cylinder (April 8, 2015) in the midst of my clutch replacement I had water draining out of the clutch hose cover. In short the water promoted rust and ruined the connecting point of the hose to the fitting. When considering the lack of drainage and not having a chance to dry out I wonder how long the bottom connector had been rusting as 2/3 of the connector crimped portion was rusted away.
If you have access or are working on the low end try to trim the clutch hose sheathing/cover up a couple of inches from the slave cylinder so water can drain out. Or if replacing clutch hose or any other reason you may be in the lower end of the moto trim the hose up and figure out a way to keep the sheathing/cover from sliding down and promoting rusting of the fitting connector. Perhaps just trim the sheathing off except for contact and tie/mount points to the moto as water won't bother the hose but of course just rusts metal.
The main thing is make sure water can drain out the bottom of the hose/cover and allow the lower connection to dry out.
