Clutch pushrod seal

[kmev]

I'm getting ready to put the bottom end of my narrowcase back together, and looking through my gasket and seal kit I cannot find a seal to match the old clutch push rod seal that came out (the one on the left.) The small seal on the right has the correct ID, but obviously the OD is much different. Is this what the new push rod seals look like, or will I find a place for this one somewhere else in the motor? I figured I'd check here before I order a new seal from Domi racer and have the identical piece arrive.

Well, it would seem that the pushrod seal is no longer available. I'm going to make my own out of rubber, and if it ends up leaking like a sieve Lacey's makes this sweet little piece: http://www.laceyengineering.com/ducati/ ... p-224.html

I can't be the only one who's run into this lately. What have others done?

Does the clutch rod seal that Lacey's sells go on from the inside or outside of the case?

" I cannot find a seal to match the old clutch push rod seal that came out (the one on the left.) "

____ A new seal is usually about only a half-mm smaller than a used one.
There's no real need to find a new (stock) one, if the old seal has not hardened (or, doesn't offer to smear an excessive amount of black onto your fingers) ...
I have simply flipped them over and backed-em-up with a tight fitting, thin fender-washer. -(Commonly found with roughly the same O.D. and with an ever-so-slightly larger I.D.)

I didn't expect the seal to be obsolete, so I pulled it out through the bearing with a needlenose pliers, and now there is a small tear on the sealing surface. I plan to reinstall the new one when I replace the bearing so I don't have to remove the swages on the outside of the case.

I emailed Lacey to learn how their conversion works. I assumed it pressed into the existing hole from the outside, but I looked up their seal number and the OD is of the seal itself is 15 mm (the same diameter of the OEM seal) so I'm not sure how the adaptor goes in.

I wonder if this is something Damien Birch would be interested in producing?

Not that it would come in time to help kmev. But if you can't find something and you ask Damien about it, sometimes he creates it and adds it to his catalog. Most everything he makes in rubber was once no longer available and became severely overpriced unobtanium until Damien started making it again. And everything Damien makes is 100% accurate and indistinguishable as a reproduction.

Here in Spain is difficault also to find this spare, then we use a ruber bougt in a plumber shop
