Here is what I found out after opening up the BB. The opening from the seat tube is tiny! If you are going to put oil down there to help keep it lubed, err on the side of plenty. I used a spray can of Teflon and 3 in 1 oil in healthy doses. Because there are no seals between the spindle and cups you might be able to sneak enough to the ball bearings through that route.
i am happy to have gotten the cotter out regardless. My LBS has been around over 40 yrs. they still have SA parts in their drawers and bins. I will see if the pins I come up with look decent or go talk to BikeSmith.
