Mine started leaking oil fairly soon. After a few months I opened it up and replaced the oil/water emulsion with fresh oil. Then I used it for another eight years without worrying about it, eventually replaced the rear end because I lost an irreplaceable nut.
At the first papercreters gathering we replaced the oil in Judith's mixer because it was mixed with water. In both cases I saw no rust or unusual wear due to the water mix.
So to answer your question, the pinion shaft seal will leak both ways but it doesn't seem to be a problem. Not much oil into the pc, and the water in the oil seems benign.

Hi, I thought I'd ask if anyone had had experience with the pinion shaft seal in the rear end letting water into the rear end and contaminating the grease in there. I'm remembering a post about someone having oil come out, although I don't remember if they said just where it was leaking, and got to wondering if the pinion seal is proving adequate for keeping water out as well as oil in. Thanks ahead, Dan
