clutch not engaging.. - Ducati.ms

meme · Sep 1st, 2011, 7:08 pm

i have a 2011 696. if i have the bike in gear and depress the clutch and try to move it, it will not move.

i've bleed the system so many times and wasted 2 big bottles of dot4 brake fluid.

no air bubbles after the first few pump. if i keep bleeding it, i only see fluid.

i removed the slave to see if anything go stuck and nothing is in the way.

i also bleed the brakes at the same time and those are working just fine.

anyone have something similar problem?

So how did the clutch act before you started the clutch bleeding? With the bike not running and in gear would the bike roll when you pulled the clutch in? Sometimes there is some drag on the clutch when the bike is not running and you try to roll the bike in gear with the clutch pulled. This could be possible since your bike is new and things aren't worn in. I'm not sure on the Monster but on some bikes with wet clutches it's possible to see the clutch stack through the oil fill hole. If you can visually see it squeeze the clutch and see if the plates are separating.

It rolled fine in gear with the clutch pulled. it was running fine and clutch worked fine. my brake fluid was really black so i decided to flush it out. figured i had my tools out i should do the clutch.

ill check the site glass you mentioned. im thinking maybe the slave is sticking if the fluid was dirty or had junk in the fluid.

if the slave was stuck could the lever still be pulled in? i would think not but im not a pro. so any info would be great.

thanks

Not the sight glass. Through the actual oil fill hole. You may need to shine a small flashlight inside to see down in the hole. I can see my clutch on my Hayabusa this way.

So it was fine before you messed with it?

There has to be air trapped in the line, try cracking open the banjo bolt at the master, sometimes air gets trapped at the highest point.

Be sure to cover up any important stuff that you might not want brake fluid on!

Good Luck!

Tell me about it! worked great till i messed with it.

ill check if i can see through the fill hole.

i would imagine there was air in the line, but damn i've bleed the system so much my forearms are sore...

ill check that upper banjo bolt tonight. i didnt try that yet.

thanks for the input guys

Unless you open a fitting on a line or are fighting an air bubble in a line. There is really no reason to ever pump the lever when you open the bleeder. I always just let gravity do the work by just keeping the reservoir full and open the bleeder. This can take time but you can sit back and drink scotch while the gravity bleed is working and you won't suck air into the system as long as the reservoir is topped off. Give it a try next time.

You didn't happen to change levers, too? If so, could be the lever is not fully returning. If you release pressure (open the bleeder with a tube on it to prevent spitting on your shiny bike!) with the lever at rest, does the clutch then engage?

Also, the Monster 696 has the APTC (slipper) clutch; maybe something went awry in there, preventing the pressure plate from returning fully? Just thinkin'.

Good luck!
