Is this the crank seal? *pics*

yesir! that sleeve will come out and then put some lithium greese inside the seal before or after you have installed it. whatever you think is easier. and when i install the sleeve i usually put a small ammt of yamahabond on the inside of it so it will make a good seal. it is supposed to be a machined matting surface but i have found that sometimes it leaks. glad it wasnt the case!! seals are easier 
Use White Lithium spray in grease ONLY ON THE OUTSIDE! You might need a socket to tap it in to place. This is what you need. It's also great for greasing your chain and lubing bearings. http://www.google.com/imgres?q=whit...=130&tbnw=130&start=0&ndsp=16&ved=0CFsQrQMwBA
i think you mean on the inside of the seal not the outside. where that sleeve turns inside the seal is where the greese goes.

Ok let me get this clear:
So that thing I circled in yellow with arrows is the sleeve you are talking about. I need to remove said sleeve, take my seal put white lithium on the inside rim of it, then place the seal over the sleeve and push the sleeve and seal in together?
Or do I leave the yellow arrow circled thing alone, put white lithium around the inside of the seal and just press it in flush?
take the sleeve out. install the seal like you said then put the sleeve inside after not together
Ah! You see I found the mangled seal completely in front of the sleeve, and thus thought the sleeve just sits behind the seal.
So lets go over this again:
I take the sleeve out, put white lithium on the inside of the new seal I put the seal around the shaft flush, then I take the sleeve and force it into the inside of the seal? How far?
yes, the seal will be flush with the cases then the sleeve will go all the way against the bearing.
These guys are steering you straight^^^^^. Pull that collar out, install your seal flush with the outside of the case, then I also put a little yamabond on the inside of that collar, Then slide it in.
Iirc my Yamaha seal had a small bead of grease in it already. I've never added more to it when I installed it

Push sleeve all the way in against bearing. Seems I've seen reference to the sleeve it'sself actually leaking. Just make sure the sleeve has either oil or grease on it so seal isn't dry. Just looked in Clymers manual.... "Pack lip of each crankshaft oil seal with waterproof grease"
If I understand correctly, you guys suggest keeping the outside rim of the seal dry, the inside of the seal rim coated with lithium grease, and the inside of the sleeve (not outside) between the shaft and sleeve coated with yamabond?
How redundant is the yamabond? Worth going out of my way to go get some?

I've hever heard of yamabond used on this , however I have never assembled a bottom end either!! Good to know!
its not something in the book but if you have ever had a leak here then you would know it could be easier to prevent by using it there...
thats right. banshees do something similar but they have a keyway there
