TE/TC TX300 Water Pump Seal Advice?

I'm getting a small amount of milky white goop in my oil. It mostly accumulates in the underside of the oil filler cap. But there were a few drops in the oil last time I dumped it. So I ordered a oil seal kit from Slavens. Looks like it comes with a seal and new cover gasket.

But my service manual does not show any replacement procedure for the seal.

After taking off the impeller, how do you pull your seal out without damaging anything?
Or should I be pulling the entire clutch case to do the job?

you can snag a seal out with picks etc., but of course best to do it on the bench after pulling the case cover. PS the are seal removal tools that cut thread into the seal then you use a puller to yank them out. add some heat before trying to pull.

Thanks! I noticed that the inner-most part of the seal (the part that is right up against the shaft) was all rubber, with no metal behind it. I was able to pick a small notch out of it to get in behind the metal in the seal. But the seal was so tight (even with heat) that it bent my pick. But I was able to stuff a flat head screw driver behind there and it popped right out.
