CAM SHAFT DRIVING WHEEL BOLTS GETTING LOOSENED


While sailing, abnormal sound heard coming from the flywheel and timing wheel.. Engine stopped and on investigation found, camshaft driving bolts had become slack, and the timings have changed. Bolts tightened and new lock washers used, timing checked and adjusted. Engine restarted, found satisfactory, and the vessel proceeded on the voyage.

Lesson learnt :

The routines are to be done religiously and the inspections should be done and checked by senior officers to avoid such incidents during sailing.
