Ok, I understand now. My "brass piece" is powder coated black on my table. There is no brass to be seen. They should have referred to this "piece" as the motor cover and that would have saved me alot of confusion. I will use the syringe method as was suggested by actusreus as I cant see any other way to apply oil without making a mess. Thank you actusreus for helping me to understand this better. It was a big help.
