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.

thanks a lot garyracer, thats what i thought but i just wasent sure..

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.
