Abstract
A submersible pump assembly having first and second components that are coupled together has a removable externally splined sleeve. A key is located in the keyway between the shaft sleeve and the shaft for transmitting torque. A threaded fastener secures to a threaded hole extending inward from an end face of the shaft end coaxial with an axis of the shaft end. The fastener has a head that engages an outward facing shoulder of the shaft sleeve to releasably secure the shaft sleeve to the shaft. A coupling sleeve has internal splines that engage the external splined section of the shaft sleeve. The coupling sleeve is in engagement with a shaft end assembly of the second component for transmitting torque between the shafts of the first and second components. The head that of the fastener transmits axial loads between the shafts of the first and second components.
