High Quality Diesel Head Rotor 096400-1700 For TOYOTA 1HZ VE Pump Parts Rotor Head Spare Part

When the high-pressure diesel pump fails, attention should be paid to fault diagnosis and treatment to prevent the fault from expanding and ensure the safety of the diesel engine. The first is to standardize the maintenance methods of high-pressure diesel pumps. According to the diesel engine maintenance level, the high-pressure diesel pump and various fuel filters should be inspected and maintained. There are four main deficiencies in maintenance and repair. First, the high-pressure diesel pump is not maintained according to the time requirements; second, the seals and other gaskets are not replaced as required after disassembling and inspecting the high-pressure pump; third, the valve surface of the valve body is not ground and inspected. Fourth, the nut was not tightened as required after reinstalling the high-pressure diesel; secondly, the fault was discovered through the phenomenon of precursors of failure. When the diesel engine is running, the on-duty personnel strengthen comparative analysis of each operating parameter and discover hidden faults through parameters, operating conditions, etc. High-pressure diesel pump plunger wear failure will have precursors or various abnormal symptoms in the early stage. According to the failure signs, timely inspection and repair will be carried out to avoid the occurrence of the failure; finally, be good at analysis and observation during the troubleshooting process to quickly find the cause of the failure. Engine management personnel usually analyze and summarize fault phenomena and use the method from the outside to the inside to analyze and eliminate them. When a fault occurs, it is necessary to determine which system and component the fault originated from as soon as possible. For the high-pressure diesel pump plunger wear failure, the main reasons are the failure of the high-pressure diesel pump itself and the fuel system problem. The management of the fuel system is very important during the use of the diesel engine.
