Shimano 3S Internal Gear Hub Service (Part 1)

In this video, I disassemble and give some tips on lubricating a Shimano 3S, a cartridge-style, three-speed hub from around the 1970s/80s. It can be found on older three speeds, and was a cheaper alternative to the more popular Sturmey Archer three speed hubs. As a result of that, there is much less information online about Shimano's early hubs. So, I thought I would give some guidance to any others who wander down this path.
