Title: Clutch problem
Post by: ferry554 on June 18, 2010, 03:53:15 AM
Hi there,
I believe that i can t build enough pressure with my clutch.
I want to refill the fluid in the clutch, think that i did everything correctly.
Did a tube on the deflating slide and squeezed in the lever, turned the slide open and closed it again while holding on the lever. After closing i gradually released the clutch lever. I did this till all bubbles where out. And during this i kept the fluidreservoir at level.
Did the same thing with my brakes, and they are functioning well.
I took off the "clutch system" ( don't know the name of that piece ) frome the generator cap.
I believe that the power transmitted on the "clutch-pen" (don't no if the word s correct) is enough.

Sorry for the bad English, i m just a stupid dutchman.
Hope someone an help!

To help your english translations
clutch system = Clutch Slave
clutch-pen = (clutch) push rod.

The process you described is called 'bleeding'. Bleeding the hydraulics for the clutch on a Ducati can be a real hassle. It sounds as if you've done everything correctly - but it is common for air bubbles to be trapped high in the system, near the master cylinder (on your handle bars). One old and easy trick to address this is to pull the clutch lever to all the way to the bar, and to strap it to the bar over night or longer. A zip-tie, wire-tie, even tape can be used.

Do that, and if you're still having issues after that - we'll keep working

How are you testing it?  Is the rear wheel off ground?  If you have a wet clutch and bike up on stand you will not be able to turn wheel by hand (with bike in gear and lever depressed) until you heat up engine oil.  I learned that the hard way.

Good point. A wet clutch transmits a small amour of power to the wheel even if the cultch is working properly and disengages fully at full lever pull (or before)
