Upper Unit lower Oil Seal

[TXS V20]

Well, you're definitley correct about breaking the screws off and I'd been told by folks that have done this before that the lower oil seal of the upper unit (correct as you described it) could be removed by a half of a gear puller with some leverage (without removing the upper unit). I couldn't/didn't mangae to accomplish this. So looking for impediments, i broke the dang screw off the water tube cover. Question is; what's next ? and, it should be obivous by now I ain't a mechanic
