I’ts been awhile, but I believe you can remove the snap ring, spring and cup washer, then remove the carbon ring. The big O-ring inside the carbon carrier can then be replaced. The carbon ring is brittle, and easily broken. Use a bent pick tool to gently remove the old O-ring. It will be hard as a rock. #11 and #12 will remain between the crankcase halves. I don’t think there is any reason to split the halves. You can just replace the big O-ring inside the carbon ring and be done.
