Another 83 Expedition Question: What Bottom Bracket is this?
The last step in tearing down this aforementioned 1983 Specialized is removing the bottom bracket so I can spray the frame with frame saver.
Admittedly, I have only ever worked on cup and cone bottom brackets before, and have no idea what the deal is with what I'm assuming is this cartridge bottom bracket of some kind. I borrowed my friend's ParkTool BBT-22 and it didn't fit within the splines of the bottom bracket? Is there another bottom bracket standard I don't know about? Where should I go to figure out what kind of tool I'll need to remove it?
I also thought it was notable that the drive side cup was a little proud of the bottom bracket shell.
Unfortunately, I can't add pictures because I don't have more than 10 posts, which comes up as a consistent problem for me. So realistically, the most I'm asking for is an online resource with lots of pictures of bottom bracket splines.
Thanks, for any help,

This will go better with pictures. You have two options. You may introduce yourself in the section for newbies and talk to a few people. You'll hit 10 fast. Or you can upload the pictures to your profile and someone will then post them in this thread.

As for the inquiry, that bike should have come with a Suntour sealed bottom bracket.
A Suntour TA-230 is technically the tool that's designed for these bottom brackets. I've gotten these BB's off (of non-rusty BBs) with an adjustable pin spanner. The out of production Park yellow pin spanner also fits the slots.

6 posts since July 2020 doesn't sound like its a consistent problem. Make some more posts already.

I can't tell 100% from the pic if the cup rotates separately from the ring, I assume it does. For removal can you just use a lockring tool, or even a punch/drift to loosen the lock ring and pull it out that way? For reinstall would the OP need something to hold the cup in place as you tighten the lockring or can you fudge it with just a lockring tool?

I've never seen those suntour BBs before. Learn something new every day...

Seems like the majority of these kinds of questions, the answer is Phil Wood.

I don't really have a plan with it yet. Eventually I need to replace derailleurs as the huret jubilee plastic disaster is kinda mangled. other than that I hope to restore using the parts that came with the bike so that I can load it up with some camping gear and go on some overnights

I count 18 splines. If the drive side and non-drive side cups look the same, it's a Phil Wood. You would need to buy or borrow a Phil-specific bottom bracket tool.

I just finished my '83 about a month ago. Mine had the Suntour bottom bracket with the 2 lock rings as Vintage_Cyclist posted, which I had my LBS remove. I swapped it from a modern cartridge square taper bottom bracket since I didn't want to deal with a Suntour bottom bracket that I don't have the tool for, although I could have just replaced the clapped bearings if I wanted to.
Your bottom bracket definitely looks like a Phil - nice score.
