New Melones Turbine Overhaul
Gracon disassembled, overhauled, and reassembled two turbine generators. On each unit, the bottom ring, head cover, turbine shaft, servomotors, bearings, and bearing housing were all overhauled. We also field machined the discharge ring seat, the stay ring, and the headcover, installed greaseless bushings in the wicket gate journals, and replaced the wicket gates and runner.
