Well, I need to know if I'm missing an oil seal here (refer to pic below) just up and left of the left-hand bearing set-plate hex nut, my disassembly pics (of which this is one) show what looks like a seal. My cases were blasted and I'm not finding it in my parts bags, and, to boot, the parts fiche(s) is/are not turning up what I think I'm seeing. Is there supposed to be a seal there or am I hallucinating yet again??
