I bought a 1985 honda rebel! It is great, I am leaking oil out of the crank case and bought the gasket to replace it, I acquired the oil seal from the previous owner that did not install it yet. I ordered also a new clutch. Is there anything else I could replace while im in there? I want it to be the first and only time I can to crack it open as its my daily at the moment. lost the truck in Ian few weeks back. Also what size is the clutch nut? bonus points if you know where this pic was taken its kinda world famous View attachment 115406

Yes, the rubber ring which holds the sif to the oil pump.
While you're in there, remove the black ring from the pump and clean the mesh filter. The rubber ring for sure is dried out and will break.
