Synopsis
A B767 crew successfully diverted for an engine driven generator failure. An emergency was declared for an overweight landing. During taxi in main gear tire fuse plugs released. Water was applied to an incorrectly reported brake fire.
Narrative
After level off at FL290; left generator off light followed by left generator drive lights illuminated. Both QRH checklists completed for both malfunctions. Captain decided to fly the aircraft while I (First Officer) ran both checklists. The Relief Officer returned to the cockpit after both checklists were already complete. Captain also decided to fuel jettison approximately 36;000 LBS of fuel at FL290. ATC was advised of both the emergency and fuel jettison simultaneously. All of the center tank fuel was jettisoned except for the last 1;000 LBS. After jettisoning fuel; we requested lower altitudes to facilitate fuel burn. However; it was determined that we would still land overweight (gross weight approximately 337;000); so we ran the overweight landing checklist in the QRH and determined that we were ok for the Flaps 25 landing based on runway limited and climb limited weights. We requested the longest runway with a direct headwind component. Landing was smooth and uneventful. Initially; airport rescue and fire fighting said we looked good for taxi to the gate; but a few minutes later; someone called Tower and reported a fire on the right main gear. (Still not sure who reported this to Tower). When the Fire Chief arrived again to our plane; he scanned the plane and reiterated that there was 'no fire and that the brakes were not hot; only detected as warm'. I suspect that the brakes did heat up while we sat there for what seemed to be a long time; and eventually a fuse plug blew on one of the right main wheels (front left wheel); and we had to have passengers bussed to the airport. The Fire Chief told me that he never saw a fire; and we based the decision to not evacuate on his viewpoint. They did spray the left main gear to facilitate cooling. We were eventually bussed to terminal where a new airplane was waiting. The airport rescue and fire fighting were outstanding in communicating with the crew; ground personnel did a wonderful job of coordinating the transfer of passengers; crew; luggage and catering to the new aircraft.
Second reporter narrative
We had our left generator quit about 50 minutes after takeoff. Talked to Dispatch and were told to divert. Declared an emergency; dumped 36;000 LBS of fuel; and made an overweight landing at approximately 337;000 LBS. Landing was normal with a soft touchdown and normal rollout using most of the runway. During taxi in while turning from the parallel; the Tower told us to stop because we had a wheel fire. I was skeptical because the emergency equipment; which surrounded us as we exited the runway; has just left and had said nothing. I called for them to return and investigate. We received numerous conflicting reports from 'you have no fire; its just warm' to 'there are/were some flames.' The Fire Chief then decided to douse everything with water just to be safe. When he did that two of the fuse plugs on the right side let go. We had to then shut down and remove the passengers by bus to the terminal.
