The frequency of piston drawing-out check varies according to the daily maintenance, especially the lubricating oil control and load (overload and excessively low load). Therefore, the supervisor is required to decide the proper frequency. However, the initial overhaul and check should be performed at the time mentioned in maintenance manual which is around 8000- 10000 running hours. From then on, decide the subsequent check schedule according to the overhaul checking results, an increase of blow-by and an increase in lubricating oil consumption. When the lubricating oil consumption has become twice the initial value, overhaul and clean the piston, and replace the piston rings.
