Solution to hydraulic pump oil leakage of Komatsu 130 excavator

Check the spindle oil seal: Damaged or aged spindle oil seals are one of the main causes of oil leakage. If the oil seal is found to be damaged, it needs to be replaced in a timely manner. In addition, wear at the end of the spindle may also lead to poor oil seal sealing, and it is necessary to inspect and repair the wear issue at the end of the spindle.

Lubrication management of Komatsu pc200 excavator: Poor lubrication can also cause hydraulic pump oil leakage. Ensure that the hydraulic system has sufficient lubricating oil and regularly check the amount and quality of lubricating oil to ensure good lubrication effect.

Check the seal: The material, elasticity, and wear resistance of the seal have a significant impact on the sealing effect. If the sealing material is poor or the mechanical strength is low, it is easy to cause leakage. Check the quality of the seals and replace them if necessary.

Adjusting system pressure: Excessive system pressure or insufficient pre compression of seals can also cause leaks. Adjust the system pressure appropriately to ensure that the seals are working in the correct pre compressed state.

Check the oil temperature and viscosity: Excessive oil temperature or low viscosity can affect the sealing effect. Ensure that the oil temperature is within the normal range, regularly check the viscosity of the oil, and replace the appropriate oil if necessary.

Regular maintenance and upkeep: Regularly inspect various components of the hydraulic pump, including pipe joints, cylinder head and cylinder liner sealing parts, to ensure that they are not loose or damaged. Regular maintenance and upkeep can effectively prevent oil leakage problems from occurring.

Through the above methods, the problem of hydraulic pump oil leakage in the Komatsu 200-8 used excavator can be effectively solved, and similar problems can be prevented from happening again.
