This looks like the RN type handle. The rear bezel / escutcheon is spring loaded and has a D shaped hole. You slide it away from the handle end and pull it off the spindle. There is a "bar" inside the hole that fits on the spindle that does the driving of the mechanism. This fits into a cut out on the end of the spindle with a spring loaded ball in it.
