All my life when I've greased a bearing or a gear, I GREASE IT BIG TIME. I don't just put a dab on and call it good, I coat the whole bearing or gear and leave no part bare.
When I rebuilt the motor on my 1936 vintage 15-91 I really greased the motor drive gear. And I made sure that everything else was oiled well too.
Yesterday when I did my 201-2 I noticed there was very little grease on the motor drive gear and even less on the feed dog and bobbin drive gears. They are greased now big time.
I'm not worried about the wick grease getting into the motor housing, but from what I saw with the 201-2 even the little bit they had in there had been flung off all the way around the inside of the housing.
So my question is, how much is too much?
