Splitting case

[Sweet B]

Prior to splitting the case do I need to remove this ring, if so how? I’ve seen videos online where the ring stays in place and the half slides out from under it. Any help would be much appreciated.

Hard to tell from the photo, but it looks like the seal may be attached with black RTV. That is how I attached my front seal. Just cut between the case and the silicone to free the seal, then pull the case apart. If the seal is inside the flange of an aluminum adapter, the case should pop apart, and the adapter & seal will stay with the crank.

Got it thanks. What brand of RTV are you using and where did you get the oil filter adapter? If I had that in the beginning, I wouldn't be having these issues.

I used Ultra Black RTV from an auto parts store. The "oil filter adapter" is actually a complete oil pump & filter assembly. Here is a link to a YouTube video that explains it in detail: I used a Wix filter (51056) because it has high burst strength, and it cleared my exhaust tubing nicely.
