Is this ok? I have a small cut in the blue seal of my novarossi 17011 front bearing. no idea how it got there!
I dont have any leakage or anything. I just dont know if
it could have an air leak? Could a small cut in the seal affect tune or operation?

Thanks

If it worry’s you then remove the seal then clean it really good with some rubbing alcohol then ad some high temp RTV. I’ve had to do it before for a bearing shield that kept popping off.

Just change the seal.

Oh, can you give a link to only a seal fitting that bearing?

It is wrong to say/think the seal is airtight, that for sure it is not. The seal is only to keep the grease better in and the dust better out.

Inside the engine with the groove in the crankshaft and a small channel between carburator and front bearing does give a kind of seal.

you just made a seal cry

Maybe this Seal will make yours feel better.

my SEAL wins!

a whole ton of yes, ya this one, yes yes

That's not the issue or the discussion. They also never sold only the seal. That would be cool, huh

but you could use the seal of an old bearing though

The seals aren’t airtight. They’re just there to limit the dirt inside the bearing. Leave it as is, drive it like you stole it, then replace the bearing before next season. Avidrc.com is your friend.
