Remove the sprocket. Get hold of the sleeve that slips over the countershaft and wiggle it off. Once that's out of the way, it's just a matter of sliding a small screwdriver or pick under the lip of the seal and popping it out. Be sure to replace the sleeve (collar) if it's grooved by the seal.

You can also drill through the seal and then screw a screw into it which will push against the case, bringing the seal out. Or just use the screw as something to pull or lever against.

I have not tried this method on this particular seal (so I could be wrong) but I used to do stuff like this all the time on various motors.

Some seals have steel casings which makes this idea a little more likely.
