crank shaft seal vs. sprocket shaft seal

Need to replace the crank seal (I think it'ss HD PN 12026B?) on my '92 Evo. 2k miles into the new belt drive and the original factory crank seal is leaking from behind the stator cover. I can't find a parts diagram, and all the parts deals call it different, but the PN keeps coming up the same (12026B). Is this the correct seal?

Related question: How does the stator cover come off? Assuming some type of puller needs to be used but it is just held on by the magnetic attraction? It moves slightly back and forth on the crank splines when just sitting on there (1/16" or so back and forth rotation), but DOES NOT move at all w/ the front pulley torqued down to spec. Is this normal?

The trick is to install the crank seal backwards now that you are open primary.

I just put allen wrenches in the stator cover and work it off. It's held on with magnets

yes 12026B is what you need. I use to long bolts and slip them through the holes in the rotor and with one hand squeeze them together to wedge in the rotor and pull it off.

I have good luck with Accel and other "double lip" sprocket shaft seals.
HD OEM installs the sprocket shaft seal so it can release pressure to the chain case (closed primary) and leaks are not a problem. With an open primary, flip the seal with the lip inward to reduce leakage.

John/BT100/MW,

Thanks. Wouldn't have thought about reversing the seal like that for the open primary. This is the kind of info that's kept me linked into CC.com for almost 7 yrs. Again, thx.
