A method for repairing a discharge ring of a hydraulic turbine with a turbine runner in place includes: mounting adjustable fixtures to runner blades that are approximately evenly spaced around the turbine runner, where each adjustable fixture is mounted to a different runner blade at a different predetermined vertical position with respect to a surface of the discharge ring; attaching cutting equipment configured to remove material from the discharge ring to each adjustable fixture installed on the runner blades; installing a drive unit configured to rotate the turbine runner; controlling the drive unit to rotate the runner at a specified speed; and controlling the cutting equipment attached to each adjustable fixture to concurrently remove material from the discharge ring as the turbine runner rotates.
