Evo 1100 clutch slave seal change.

crawsue · 23-08-2022, 03:17 PM

Limped home on Sunday with very little clutch fluid and difficulty selecting neutral, problem appears to be leaking at the slave cylinder and a slightly damaged (bent) push rod. Question is , looks like a special tool required to access cylinder innards to replace seals….any suggestions?

For all the aggro just buy a new/second hand one or bite the bullet and get an Oberon one or something similar.

Yes it's £100, but as Rollo says it'll be 100 well spent and a lot of grief saved, plus the added bonus of a lighter clutch

If your set on sticking to std, new one's can be had for around £60 as people flog them off after changing to a funky billet jobby

Thanks guys, had a chat with Vince (Luddite) and it appears that Ducati don’t list either a seal kit or a tool for dismantling, so Oberon (or similar) will be the way forward. Think the bent rod is probably collateral damage of the broken chain that I suffered a couple of years ago….and the rod has damaged the seal….bummer. Please see my other post in “wants”.

Another vote for Oberon here! Fits perfectly and just works.

adie851 · 04-01-2023, 05:03 PM

Oberon are good...would've thought you could get a seal( kit) for the slave cylinder on your bike...try Moto Rapido....they're excellent for obtaining Ducati spares..I've used them alot...very helpful...

adie851 · 04-01-2023, 05:14 PM

Although I'm not familiar with your model of bike , most Ducatis ....the slave cylinder is held on with three allen key screws....the way to extract the slave cylinder piston is to top up the master cylinder with fluid, remove the three allen keys which hold the slave cylinder onto the engine and pull it outwards and you'll see the end of the pushrod shaft,then gently pump it and the piston should pop out..be very careful..wear gloves as the fluid is good at stripping paint and not kind to your hands...Hopefully that master cylinder could be the same as on several other Ducati models.If it is then a seal should be readily available.
I could be wrong as I've never worked on an 1100 EVO monster....hope this is of some help to you .Let me know how you get on.

Cheers, adie851

Should have finished off this thread earlier….fitted an Oberon and replaced the bent rod….clutch now flawless. Thanks for all the support.

crawsue · 09-07-2023, 08:26 PM

Clutch has become very “short” and with a very early, quick biting point….perhaps needing bled but did I read somewhere that the standard master cylinder and the different bore of the Oberon were not, perhaps a perfect fit ? Gear changes and finding neutral are fine….but quite fierce from standstill when cold…..any thoughts etc etc…..

Ron1000 · 09-07-2023, 08:35 PM

Crawsue. I can bring mine through to you sometime to see the difference?!?! Might also let me see how yours handles compared to mines…mines has developed this weird very light steering almost twitchy thing in corners. Wonder if it’s anything to do with the new tyres I fitted.

crawsue · 10-07-2023, 12:48 PM

That’s a plan James….are you still thinking of organising an area UKMOC run this summer?
BTW I’m running Pirelli Stradas, just fitted a new rear for yesterday’s run….I’m very happy with the performance and the price !

adie851 · 10-07-2023, 02:28 PM

Try letting the bike warm up for a good five minutes and pump the clutch lever before you set off...assuming its a dry clutch on that model.....or is it a wet clutch..as I've said b4 I'm not familiar with that model of monster.....

Yep still scheduled in for Sunday 23rd July for run. I’ll get my bike back from service on 21st…hopefully handling issues resolved.

crawsue · 10-07-2023, 03:58 PM

It’s a wet clutch Adie, I’ll compare it with James’ when we meet up soon. It’s working, but incredibly “quick to bite” …especially in the few moments after initial start up. + a very early “bite” when releasing the lever. Bleeding the system is next on the “to do” list.

Ron1000 · 10-07-2023, 04:57 PM

Crawford,
I paid attention to my clutch bite this morning, it’s fairly grabby (I always stall it after being on the street triple) but nothing too bad not aggressively so I’d say.

Also I did suffer clutch issues years back (2017). Struggled to find neutral, and find a gear was getting progressively worse; that turned out to be air in the lines.

Also bleeding the clutch is very very easy, I can assist if you need. I also have one of those very handy motion pro mini-bleeders to hand that help the job no end.
