I've used the search function and while I find loads of references to the seal everyone seems to know the answer to my question so its never posed or answered.
I'm fitting a new/old trans to my car to replace one with a cracked casing round the starter motor. New trans has been rebuilt but has no output shaft seal, so I ordered a Timken 7300s. This seal has a notch on the outer rim and a small hole in the extended rubber seal on the opposite side of the notch. Which way up should I install it? Is the hole a breather and therefore lives at the top, or a drain and therefore lives at the bottom? I believe its a breather and should live at the top but wanted to be sure before I install - might only be a $7 part but shipping and taxes and the value of the British pound at the moment make that an expensive part! Thanks.
