Leaky Bleeder screw on Evoluzione clutch slave

[rockaduc]

I recently installed a 30.5 mm bore EVO clutch slave on my 05 s2r.  It will NOT stop leaking from the bleeder screw.  I have checked the threads multiple times and I didn't mess them up by galling them.  The bleeder screw will install and uninstall freely, but when tightened down, there is still a leak coming form the area where the bleeder screw goes into the banjo bolt.  I was thinking of trying plumbers tape as a fix, but I would rather just get this thing to work like it is supposed to.  I tried the EVO site, and it doesn't offer any help beyond the instructions that I already have.  What am I missing?

Any advice before I give up and accept my fate of getting reamed by the dealer for $95/hr??

Bleeder screws seal on a machined bevel seat inside the housing.

They don't use o-rings or the threads to seal.

I'd look for dirt, or damage to the seat or bleeder.

Thanks DP.

I bled the system as dry as possible and disassembled the bajo bolt/bleeder screw.  The bleeder screw threads were fine, but the banjo bolt threads where the bleeder sits were FUBAR...I'm a dumbass.  Anyway, I swapped in the stock banjo/bleeder combo and I'll keep my fingeres crossed that I didn't make the beast with two backs anything up this time around...now I just need to get all of that bloody air out of the system...

On a different note, I'm taking 'er in to the dealer for a new tank as the original has warped (yes I've filed a notice w/ the NHSTA and signed up for the plastic tank groups here).  I'll probably "mention" the clutch issue then and see if they don't mind checking it out while they are at it.  I have a pretty good relationship w/ the service manager at the dealer, so I should be good to go.

It sometimes helps to elevate the slave above the master.

You can use a clamp to hold the piston in place.

Mine did the same thing, I took the silver "crush" washer and replaced it with the copper "stock" one and had no problems since. I personaly dont undersatnd why they would use the steel ones. copper is way softer and provides the ability to crush, causing a good seal. Ooops, after reading the full post, I see that she is leaking from the bleed to the banjo. Why not use the stock banjo? I have done that in the past.

I think I got Evo bleeder bolts from Desmotimes, and the crush washers- they aren't usually reusable. Needed one for the master end to get the air out after I installed the evo slave.

Thanks for all of the responses.  It might be just me, but I actually like the OEM bleeder screws better than those provided by EVO.
