The Centauro motor I put together this spring runs well, but the lip seal on the crankshaft behind the alternator leaks. Any thoughts on what I did wrong?

There's an o-ring too. #7 in this illustration:

Why do you think you did something wrong? I use tape over keyways & threads or anything that might damage it on instillation.
Didn't leak right away did it?
Charlie's got an idea

There's an O-ring inside the part#8, the sleeve isn't there? Was that replaced and lubed as it went in/on? Also the front seal should be a directional Viton one I believe? If a Nitrile one was substituted it won't of lasted long due to the heat.

I think the seal rides on #8 and in the pic oring is on the wrong side of it.
-
I replaced the lip seal, but reused the o ring because it seemed to be ok. Have there been any reports of poor quality seals? I don’t like to just replace parts without knowing what caused the failure - that usually leads to repetition of the same mistake.

O rings are usually deformed to some degree in regular service. I always replace them with new when things are apart. Mike

I use the Viton(brown) seals if they have them in that size and always new orings.

Not seeing the viton seal on the MG Cycle website. Do you know who stocks it?

I have not put one in a Daytona, I was just explaining that I use them if I can get them.
You may want to call MG and see if they can get them.

What size is it? While you may not easily be able to get a directional one from a bearing factor I'm sure you can pick up a standard Viton seal and O-Ring from there. Canberra isn't a big town, somewhere between 400-450,000 souls, but our local suppliers always seem to be able to get me most things I need within a day or so.
