Narrative:

We noticed a right primary hydraulic overheat light. We turned the pump off as per checklist. I checked the hydraulic quantities. They all showed normal including the right system. System pressure on all system were normal. The first officer and I discussed issues concerning continuing the flight and possible restrs. Maintenance, dispatch, and ourselves concluded that we were ok to continue. After about 15-20 mins after the initial overheat, I noticed on the status page that the right hydraulic system quantity decreased very rapidly to zero. The decision was made to divert. Dispatch suggested jfk. We completed all applicable checklists in a timely manner and then landed without any further problems or incidents. I announced to the passenger that maintenance was going to replace some parts and have us on our way in less than 1 hour.

SYS PRESSURE ON ALL SYS WERE NORMAL. THE FO AND I DISCUSSED ISSUES CONCERNING CONTINUING THE FLT AND POSSIBLE RESTRS. MAINT, DISPATCH, AND OURSELVES CONCLUDED THAT WE WERE OK TO CONTINUE. AFTER ABOUT 15-20 MINS AFTER THE INITIAL OVERHEAT, I NOTICED ON THE STATUS PAGE THAT THE R HYD SYS QUANTITY DECREASED VERY RAPIDLY TO ZERO. THE DECISION WAS MADE TO DIVERT. DISPATCH SUGGESTED JFK.
