The only concern I have with this solution is that you get rid of the engine case protection in case of a ripped chain.
oil leak from the clutch pushrod hole (1199 base 2012)

I loose a chain at speed, a broken engine is the least of my concerns. That being said fortunately, I have never seen a properly assembled and aligned DID break in 30 years of riding. I use the ERV 3 520 and replace them often along with the rear sprocket and I have a couple of spare motors. Good point though. Might not be a bad idea to consider making something
Sorry to bump an old thread but
I really need to see what was attached, I cant see any images that were attached. Is there a reason that the photos dont show up for me?
I really need to see this photo of this push rod modification so I can have the same thing performed on my bike.
THANK YOU!

The only thing that a few of us are modifying on the slave plate is just cutting away the bottom part which is the chain guard that has the large rubber piece on bottom off just so there is less crap, lighter and easier to work on.
The rubber seal is located on the back side of middle hole on plate can be replaced on the plate with a 0-ring but not important.

Okay so that is not what I was thinking about. Maybe you are able to shed some light on this situation. My Ducati is leaking engine oil from the clutch slave pushrod hole. My mechanic is saying that in order to replace this gasket it is an extensive repair involving splitting the case. I have done a bit of research and it appears that some people modify their pushrod adding grooves to accommodate some O-rings as the 2013 1199 does not have O-rings on the factory pushrod. Pretty much similar to the pushrod say on a 998. Has anybody heard about this and if so maybe they can share a photo of this modification of the pushrod. I'm trying to fix this oil leak any way possible. Thank you very much.
Don't know anyone that has machined grooves for o rings onto the shift rod no real reason too they typically don't leak but in design it can sweat oil but never seen it. The older platforms like 848/1098 etc believe had seals.
There clutch slave seals on its own no special seal and all the shifter case, generator cover and clutch cover is silicone. There is no reason your mechanic should be talking about splitting the case it's all bs.

Sorry, I can't find the pics that I posted. That was 2 years ago. Like Mick said I think we did the same mod to the piece. All I have left is essentially a spacer for the slave. The seal like Mick said in on the back of the center hole and it is a low to no pressure seal (mine is a fairly loose fit). Never seen a drop of oil come out of it. I can't remember if there is a pressure o ring in one of the case half's. If someone is telling you they need to pull the motor and split the case, tell them no. Now if there is a pressure seal somewhere along the span of the rod in the case and it's leaking, then the "no" could turn into a "maybe" I don't think there is but I just can't remember. It would be in the maintenance manual if anyone wants to look.
Hi all,
i have done the modification to the Push rod, and added the 2 o rings.
after my 1199 engine rebuild the oil seal for this pushrod started to leak, and as its another 22 hours ( Ducati book time) to strip the motor and replace this seal, we decided to be a little pragmatic in our dealing with this as ill pull the motor at the end of the year to replace it.
ill post a couple of pictures when im back home, as im away with work at the moment

Do you have photos/dimensions/o-ring PN for the mod? It would appear my slave push rod is getting some blow-by. lots of leak symptoms indicative of there being a poor seal on the rod. Additionally, I do NOT have the o-ring built into the sprocket cover like the later model guys are showing. I don't think that o-ring is a complete fix for this issue that I suspect will begin to haunt many of the early year 1199 guys.
Ill be putting my push rod in a lathe and putting grooves into it soon, but it would be nice to have some reference dimensions and o-rings to sort of use as a starting point.
Hopeful for a thread resurrection here.....
Guys a lot of info here was apparently posted prior to further investigation with respect to the engine case itself. Since I just got done making a few Ti slave rods I had a chance to go through the cases thoroughly. The impregnated seal on the clutch slave spacer (chain guard) is not there to keep engine oil from leaking out of the motor. It is there to keep crud out of the opening of the slave rod hole. About an inch or so inside the case where the slave rod comes through is a machined groove with an o-ring in it. If you are leaking oil out of the motor and into the slave area, that’s where you want to look.

I would agree that the impregnated seal on the chain guard plate is not there to inhibit oil flow from the case hole that accepts the slave rod.
Im fairly sure the seal inside my case is letting oil by. Which, from what I have read, is the reason ducati techs have advised splitting the case to repair the seal. My understanding is that the workaround is to machine a couple o-ring grooves in the slave rod itself.
Im not sure if you've personally performed this mod as it sounds like you had some custom rods made....if so I would be curious where exactly you placed the grooves and what o-rings you used before I just use my measurements
Thanks
Uh there is no modification. You have an o-ring inside the sprocket side of the engine case. Pull the slave off and pull your clutch rod out and shine a light in the hole. You will see it in there. If it’s leaking it’s either damage or has disintegrated. I made my own aftermarket clutch rod from a different material which has no bearing on the topic. You DO NOT need to split the case and if your mechanic told you that you do, get a new mechanic. The original o-ring can be removed and replaced through the clutch rod hole. A small plastic pic (L shaped) will pull it right out. An insertion tool (9mm diameter round piece of anything) will push the ring in and it will snap into its seat. Done

You wouldnt happen to have a PN for the seal, would you? Or even a resource where I might be able to find it myself? Ive gone through the parts catalouge at least 4 times now and the workshop manual at least twice using every relevant keyword search I can think of. I must just be overlooking it....

That would be great. Just so we're on the same page, I have my slave off, push rod pulled off, and chain guard bracket off. I used a set of calipers to measure the depth from the engine case to the o-ring you mentioned I could pull out. If you know where I can find the PN or a schematic of that area of the engine case that would be most ideal! Thanks for the help
Wouldn't the o-ring be where the clean sweeped area is on the pushrod? That looks like it's 20mm inside the hole? Anyways, that should give a good indication as to how far in you are looking. But, this is basically the reverse of the old dry clutch bikes. O-ring fixed to pushrod and o-rings slides inside the case vs o-ring fixed to the case and pushrod slides the o-ring.
