Hi, my friends 1199 base has a bad leak which appears to be around the clutch pushrod shaft. The shaft doesn't have the o rings that the older Ducati models have so does anyone know what is sealing this shaft? There was enough oil leaking to cover his left muffler at our last track day. I did also notice that the oil level was above the high mark as well, could this contribute to the oil leak?
 
Oil level being high might be probable that the oil is being pushed into the air box then leaking down on the left side.

If it's actually coming out from behind the clutch slave unit maybe the seal on the anti rotation insert is bad. That's the only oil seal I could find on that side of the clutch pushrod.




 
Oil or clutch fluid? There is a steel plate that sits between the slave cylinder and the block. That steel plate has an impregnated o-ring seal on the block side of it that seals the clutch rod. The plate is where the sprocket cover mounts. If it's clutch fluid then you have a piston seal issue.
 
It's definitely engine oil. Thank you for the tip I didnt see the o ring in this plate so I'll check out the spare parts manual again as I don't want my friend being taken for a ride by the dealership.

Do you mean the chain guard shown in this picture? There doesn't seem to be any seal shown in the spare parts document.

Yes. That long rounded metal bracket has an integrated o ring seal on the back side at the clutch rod hole. If its leaking, its probably there. The seal isn't very tight in the first place. I have has that on and off many times and so far, no leaks.
 
I don't know about the 1299 but the 1199 does not have any seal or O-ring behind/inside the steel engine case protection bracket :(

I didn't see any seal on the 1299S spare parts catalogue either...
 
The only seal I saw was the one on the anti rotation insert that goes into the back of the clutch slave cylinder. That's the pic I posted above.
 
Ok you guys are correct. Just checked the parts bin. I have an 1199 guard that does not have the o ring. My 1299 motor is mid year and does have the o ring part. Maybe they had an issue and ringed the later years.
 
On the one on the bike it looks like they machined a surface into the guard and presses in a rubber o ring like thing.
 
That's a good possibility. I'm looking at the 2015 shop manual PDF so there's always a possible update later down the line.
 
Cool mod, I'll do this as well. Easy to make and a bit more security.
Thanks for the picture!
 
I chopped mine up. I only have the three bolt holes and the rod hole, just enough for the slave function. Got rid of the rest. Been meaning to make a light weight replacement

Yeah, that plate is heavy. Are you going to get rid of the cover or will you keep it on the bike?
I'm right now doing bolt and washer on the sprocket in Ti. Will make another thread.
 
Cover is gone. I'm using a Ti bolt and washer for the sprocket. I kept just enough of the bracket material to mount the clutch slave. You can't see any of what's left of the bracket. Safety wired the bolt to the sprocket.
 
Is that 1299 part a ducati standard part or did you modify it? Do you have a part number I can quote to the dealer?
