Now - to ease your mind about the oil on your drive gear. The motor on a 301 is internal so it makes it difficult to get to if you want to repack the grease with fresh. If a little bit of oil works its way down the shaft into the grease cup on your machine all it will do is soften that 50 year old grease and give it some more life. You might find that your machine works a bit easier. Don't do it again, but you didn't kill your machine.
