Abstract
An electrical submersible well pump assembly has upper and lower motors that are filled with oil. During installation in a well, the upper motor lowers into engagement with the lower motor. The drive shafts of the motors have splined ends that engage each other within a central cavity. A vent port leads from the central cavity to the exterior for venting any trapped air located within the central cavity.
