Hi,
I've serviced couple of Shimano's bottom brackets but that one seems strange. As in RJ's the bike guy tutorial I removed rubber seal from the one side where the flange is and undone the locknut, then undone the cone nut, cleaned, regressed and tried to reassemble. The problem starts when I want to torque the locknut because it drives in the cone nut with it because there's no washer in between with a tooth that stops it from rotating I end up with overtighten bearings. There's also no slit in the axel where the washer's tooth would fit. I can't also imagine how did they assemble it and torque it rather strong in the factory. There's no way to hold the cone nut properly and do the locknut because there's socket on the way. Do you guys have any idea what kind of sorcery did they use to tighten it down?
