Left Side Oil Leak - Seals Question

I seem to be leaking a oil from somewhere behind the left side cover. I think its either the push rod seal or the gear change lever seal, or both

I'm thinking its the push rod seal as it looks like there is a chunk taken out of it. I've cleaned the areas around each up so that I can check it after the next time I ride to help determine the culprit.

I'm wondering if these seals require splitting the cases? Also, are these seals still available?

Thanks

You have taken the first step in the correct direction. I personally don't know if the seals are available, but knowing which one is a huge step. Good luck!

Killed two birds with one stone.

Cleaned both areas last night to help diagnose. While I had it all apart figured I may as well "glue" a rubber washer on top of the clutch push rod seal to help cover the missing chunk. I used RTV and the end off a rubber caliper bleed cap

Seems to have worked, at least temporarily. I just checked it after riding to and from work and everything is still clean and the oil level is still the same. I'll keep an eye on it over the next little while. God I love RTV, used it on numerous things, never fails to impress.

I'll check it later on and update this thread.

The seals are still available, not sure if you can still get OEM but you can get aftermarket ones (TourMax ao) - you can buy an engine seal kit that includes the seals for the clutch push rod, shifter lever, output shaft, kickstart shaft and the crank seals, I'm sure Jeff at Z1E carries it.

And no, you don't need to split the cases to change the seals in question (though obviously you'll need to to split the cases to change the crank seals), the seals for the clutch pushrod, shifter lever and output shaft all sit in the mission cover which can be removed by removing the left side foot peg, shifter lever, left side engine cover and front sprocket - you will also need a new gasket for the mission cover.

Removing the mission cover (can be done with the engine still in the frame):

Reinstalled with new seals:

That's great to hear OnkelB, thanks for posting that and including the pics. I wasn't even aware that that section came off separately. I'm going to see how far my temporary solution gets me. I want to get a new chain and sprockets, so hopefully it can last long enough for me to get it all, do it all at once then.

Thanks again, appreciate it.

No problem, you're welcome.
