Detail of sealing the box around the bottom bracket axle.
The bracket is sealed by means of the o-ring. Around the bottom bracket axle, an oil washer is used. The dimension of the oil washer depends on the size of the metal washer around the bottom bracket. Sealing the box around the hub is done likewise with two washers.
