Going out on a limb here but has anyone ever rebuilt their starter motor? Pretty much I ordered a rebuild kit with the intentions of rebuilding it but before doing so I had my brother cerakote the cases to match the rest of my engine. To do that he has to bake the paint and prior I removed the inner oil seal which prevents oil from the transmission from leaking past the rotor shaft into the coil section. My dilemma is not realizing it but Honda doesn’t sell that oil seal or list it on their diagrams. I’ve found the manufacture is from Japan “NOK” and a code on the seal itself says BC1693G but that’s all I know. I can’t find that part number anywhere and there are no markings saying the oil seal size or cross references. Anyone by chance have a part number or know the size?
