DREDGER – MAIN ENGINE THRUST BEARING FAILURE
The engine was SWD (Stork werkspur Diesel). One day while stopping the engine, it was noticed that the engine stopped with a jerk. It was not starting on air. Turning gear engaged and engine turned slowly with help of electric motor.
Further inspection revealed that the trust block was very hot and informed office that more time required for complete inspection.
The thrust block was dismantled and found the bottom shell had shifted by about 30o. The complete bearing was removed and replaced with a spare new bearing and trials carried out satisfactory.
