Fuel Leakage of Caterpillar Injector 0R-3190 Causes Fire Hidden Danger
A mining company in Shanxi reported that the Caterpillar mining vehicles equipped with 0R-3190 diesel injectors had fuel leakage, and the fuel leaked onto the high-temperature engine surface, posing a serious fire hidden danger. The company immediately stopped the operation of the vehicles and arranged maintenance personnel to carry out fault treatment.
The maintenance technicians found that the fuel leakage was caused by the damage of the injector body. The injector body had cracks due to long-term high-temperature and high-pressure operation, leading to fuel leakage. In addition, the maintenance personnel did not check the injector body during daily maintenance, leading to the expansion of the cracks and serious oil leakage.
The maintenance team replaced the damaged 0R-3190 injector body with an original part, and checked the other injectors to ensure that there were no cracks. After maintenance, the fuel leakage fault was eliminated, and the fire hidden danger was lifted. The maintenance experts emphasized that the injector body of Caterpillar 0R-3190 injectors should be checked regularly for cracks, and damaged parts should be replaced in time to avoid fire accidents caused by fuel leakage.
