Rotarty plate shaft removal

[nester]

A 96 XP is in need of a rotary plate shaft pull. I believe the brass "sacrificial" gear is sheered on the crank end. This is a brand new engine and the builder is going to try to give me a warranty on it, but I was going to play around with it a bit myself and see what I can find. I have the cover off the plate and the snap ring removed. I noticed a rubber seal under the snap ring and threads in the gear on my end of the shaft. Will I need a puller to remove it? If this is too much of an issue, I'm just gonna give it to him to deal with.
