main bearing seal ac generator side of engine
Has anyone ever seen the main bearing seal on the left side of the engine pop out? I started leaking oil from the gasket line on the left side engine cover, a huge leak. Hauled the bike home and tore it down thinking it was a gasket failure. Gaskets were fine, the vent at the bottom of the cover was where the oil was passing out of the case. The oil was coming from the large seal on the main engine bearing. When I pulled the AC rotor and the starter sprocket I found it loose from the engine case. It appeared unworn as well as the part of the sprocket it ride on. So I pushed it back which took some force so it didn't just fall out because of age.
Has anyone ever seen this happen before and find a good explanation for it?
