Observe the oil pressure specified for engine idling (see Table 5). For oil-cooled bearing casings, post-lubricate for 20 minutes if the turbine inlet temperature(t TE ) exceeds the following values when the engine is stopped:– 550 °C with insulated casing– 600 °C with non-insulated casingAt temperatures below the specified values, post-lubrication must be ensured until the ro-tors come to a standstill.
