There is a sleeve that goes over the shaft with an Oring on its face that rides against the inner bearing race face. That's pushed by the sprocket against the sleeve. There is a spring washer and then the nut.
The nut is aluminum and I think mines toast.
I'll know when I get home.
But I'm jsut going to order a new one anyway.
In fact...I'll order two of everything I need and call it a day.
I'm really starting to think sealant around the seal also...

Don't matter nurt or bolt. The spring washer loses tension over time. any spring steel will. Bet ya a beer that solves it. Like i said, i had this fail on mine too. I replaced 3 damn seals, 3 o-rings, and a sleeve before i figured it out man.

The CS sproket pressed by the nut is what keeps the sleeve from spinning. It's pressed between the inner bearing race and the sprocket.
It's not spinning unless the nut loosened.
Hence my thoughts about that beat up aluminum nut Norm sold me....

Jim, by looking at the fiche, i think the nut bottoms out on the end of the countershaft. The spring washer (#28 right?) is what keeps the tension on the sprocket, which pushes on the sleeve, which seals the o-ring against the shoulder on the countershaft. the spring washer is slighty concave (or convex depending on how looking at it) right?

Fooked/reused washer makes a lot of sense.

Still it looks possible to make an additional dust/dirt guard that sits on the sleeve to make it more difficult for the grud from the chain getting to the seal. Just thoughts. Plus one on it being difficult to suggest ideas to someone who has forgotten more than I will likely know.

No, just a new one. Now Jim, I'm assuming the washer actually IS a spring washer. is it curved?

I used a new one...
It looks kind of like a cup. Splined ID
Has a raised lip like a cup
I installed it lip in so it would press on the sprocket

Is there enough length on the sleeve to put a thin wave washer between the sprocket and sleeve without the sleeve running back inside the lip seal? That would ensure there is enough pressure on the o-ring.

Are you able to tell which seal is leaking?

Pete, are you talking about the 450? I purchased a few items for MUNN and they told me leaving my bike on the kick stand will cause a leak in very short order and use a stand whenever possible. Something about our seals not being designed to be submersed in oil while sitting.

Anyway, hope you get it sorted out drag.

I don't think there's room to do anything like that
There'a only one seal

also I've read if your chain is too tight right after installation it can cause it to leak again?

Run it loose for a week or two to let it seal?

This will protect the seal lip front getting cut by the shaft, and keep the inner spring in place while you PUSH it onto place. I find gaskacinch, a light coating on the outside of the seals body will help it slide into place. You should avoid hammering it into place and this can cause the inner spring to dislodge. Sometimes you have to hammer, when you do, you light taps and work it down evenly.

Mechanical & Technical

After you get the seal going into the bore, pull the plastic out and then push the seal the rest of the way home and you should be good to go.
I'm not familiar with the seal you are dealing with and how it is set up with the CS and bore that the seal fits into, but it the diameter of the CS that the seal rides on is flush with the bore that the seal fits into then there is a high possibility that the spring may be coming off. Had the same issue on a Honda motor cam seal once.
