Snap On 67 ratcheting adapter disassembly help

[Jacobs976]

I've worked on some old Craftsman round heads and odds and ends older ratchets and I have a Snap On GL72T coming in soon and they're all fairly simple but my 67 adapter is in another league. I've figured out the selector pin and gotten the retaining ring off so far but I'm stuck. Looks like I've got a newer one, can't get a good look at any date code or model number beyond 67 till I clean it up. The piece under the retaining ring doesn't have the holes for a spanner but it's not wanting to budge when I've tapped the adapter like most ratchets covers will once the rings off or when teased with a fine tip pick. Any ideas moving forward? I've fixed a skipping issue it had due to gunk but I want to at least get it disassembled to the point greasing is possible sinces it's got large teeth. Also had a local snap on guy take it with him for 2 weeks a few years ago and he couldn't find any information on how to disassemble it or even how to fix the skipping but left it soaking for a few days. Had to jettison it out once I decided to mess with it to fix the skipping.

I had one apart before but I don't remember much about it. The dealer did not want to mess with them at all, and said he does not rebuild them. Ended up ordering me a replacement.

My dealer is the same way but he took it before as a show of good will. Don't think he actually tried messing with it beyond soaking it but the soak probably at least broke some gunk loose for me. He didn't mention anything about replacements though because it wasn't technically broken since he couldn't ID broken teeth or gunk. About to try something in a bit to see about greasing mine up without figuring the plate out. Using an insulin syringe and seeing if I can force the red grease first into the syringe then into the crevices around the plate. Not expecting much but it's something to waste some time trying.

Update on the syringe. Didn't work which was expected. Did however make it a bit quieter since I basically used the tip as a tiny pick and got a little bit of grease into the mechanism. Not enough of course but if I can figure out an oil that'll work on the teeth well enough syringe might be feasible.
