Hi, I'm considering using oil to lubricate 2 Nexus 3 speed hubs that I have. I had a couple of questions:
1. Can I do this simply by adding oil via the hole where the bell crank side is? If you do this, how does the old oil with particles get out of the hub?
I know with the old SA hubs that were oil lubricated there was a way that the contaminated oil eventually worked it's way out? Is that right? Sheldon talks about this at any rate...
2. Can an oil port be added without the use of tapping (I don't know how to use a tap)?
