Abstract
Diesel engine is a type of internal combustion according to a heat engine in which the chemical energy of combustion is released in the engine cylinders, while the other class of steam energy generated during the combustion of fuel is transmitted first to the steam and only through the steam work is carried out in the turbine or engine. . One component of a diesel engine is the cylinder head. The main engine cylinder head is a very important engine part in supporting the operation of the main engine. The cylinder head functions as a cylinder cover and as a place for the injector to atomize the fuel. The cylinder head consists of the injector, exhaust valve, starting valve, intake valve, coolant. Cylinder head must be assisted with a good cooling process to avoid damage. The type of research data is qualitative research with descriptive methods and primary and secondary data sources. Data collection methods are observation (observation), interviews (interviews) and documentation. Cylinder head cracks on the main engine are caused by fatigue of materials that do not match working hours (running hours), not optimal cooling of the cylinder head, lack of PMS (plan maintenance system) and the occurrence of aftershocks (detonation). The impact of a cylinder head crack is a reduction in engine power due to the entry of cooling water into the combustion chamber. Efforts to overcome these cracks are by replacing the cylinder head with a new one, always checking and maintaining the cooling system, doing PMS (plan maintenace system) seriously and setting the fuel timing correctly according to the instruction book manual. Keywords: Diesel engine, Cylinder head, Maintenance
