Title: Slowly loosing clutch fluid - what do I need to look at / replace?
Post by: mitt on August 07, 2008, 06:11:31 PM
I had my clutch slave off last fall for a new chain install and didn't replace any seals.  I assume they are leaking?  I don't see any fluid below the slave, but it is a slow leak, like 1/3 of the pee cup in a month.

...mixing with the chain lube.

can you buy a seal for it?

If an evoluzione piston is available it's the way to go.

Brake fluid eat through everything including engine paint. Fix the problem before you ride it again..Look for a white residue..+1 on the evo clutch slave..excellent product.

So, the stock one is not worth trying to fix?  That was my question, can you get seals for the stock one, or is it better just to buy a evo one?

I've put two OEM seals in my M900.

Next time it's an Evo piston with the double seal.

I am not sure about the years, But I believe that after 2000 ducati started to use a non- rebuildable slave.  I went w/ a yoyodyne

I bit the bullet, and bought the evo kit from motowheels.  Hopefully the install is easy and I can get the air out.

But Howie is a magician.  When I changed mine out the swap was a piece of cake but it took a while to get the air out.  If I were to do it again I'd make sure the piston was  pressed all the way into the bore and do the swap with the slave not mounted on the bike, and held higher than the reservoir so nothing could drain out.  Bolt it up and then a quick bleed would probably finish it off.

Perfect addition, Dan. 

Do just barely crack the banjo loose while the cylinder is on the bike though.
