Part of the Week: Shimano Lubricator Oil Port (part 3210400 or 101)

This week's part of the week is the elusive lubricator oil port (part # 3210400 or 101) that is on older Shimano 3 speed hubs. They attach in the middle or the hub shell in small hole and allow someone to squirt clean oil in them. Many of the old hubs I come across are missing the oil port or an intact one is usually damaged. The original white plastic Shimano one is shown in the photo below. I just got ten of them in New Old Stock condition, and last time I had a few I I sold out in two days... so if you need one, hit my eBay account (planetarypedalworks) now! These can probably be used on some other hubs if needed.
