Abstract

The main relief valve is one of the control valve components that functions to regulate or limit the maximum working pressure in the hydraulic system. If there is excessive pressure from the hydraulic pump, the out-let valve will open and the excess fluid pressure will be forwarded or returned to the hydraulic tank. So that the pressure of the fluid flowing into the system remains in accordance with the safety limit. This analysis aims to determine the damage, causes of damage and repair steps of the main relief valve components. The procedure for inspection of main relief valve damage is to perform performance tests starting from road unit tests, visual checks and component disassembly to identify damaged components. The results of the check or analysis found damage to the seal and return spring located on the main relief valve, resulting in oil leakage. The cause of this damage is due to the large number of grams or dirt attached to the seal and the long playing life. The corrective step is to replace the damaged component with a new one, for preventive measures to minimize greater damage by means of regular maintenance
