Narrative:

I was first officer on flight msp to eau to lse to msp. First leg and captain was flying. About to call for approach checklist for visual approach into eau runway 4. Master caution illuminated with right gen off and CSD oil pressure low lights on. Captain called for QRH CSD oil pressure low checklist which I performed down to point where CSD must be disconnected. Captain also called 'APU start,' which I did. CSD oil temperature was rising slowly on right and temperature rise was twice the left side. We performed approach and landing checks and landed normally. On taxi-in right CSD oil temperature started rising quickly though not redline and captain called for right CSD disconnect, which I did, completing QRH procedure. Captain wrote up malfunction in mx log and then coordinated by phone with flight and mx control to put right CSD and gen on MEL with several others that were already on aircraft. Captain followed maintenance instructions and flight continued to lse and msp subject to captain's discretion with gen inoperative. Flight routine to msp termination where captain coordinated with maintenance for troubleshooting. Flight control was not aware of gen inoperative when flight was released from lse to msp, about 8 hours after MEL had been issued by telephone. Captain called from lse by phone and new release was given verbally.
