Excavator pilot oil blockage how to do?
Posted: Nov 21st, '24, 02:34
We all know that the pilot oil suction filter can filter the impurities in the hydraulic oil, and when the impurities enter the pilot oil circuit due to the blockage of the filter element, there will be gear pump, regulator and other parts wear, abnormal operation and other faults, and the excavatorweak action will affect the speed of the vehicle. If there is a blockage of the pilot oil filter, first do this:
Clean the oil filter
Clean around the tank cap to prevent foreign objects from falling into the tank. Remove the air exhaust cap and press the hydraulic tank exhaust valve (5-7 times) to release the pressure in the hydraulic oil. Use clean diesel or cleaning agent to clean the oil filter screen, remove the bolts and cover on the fuel tank, and remove the oil filter element, start the engine and run at a low speed for 5-7 minutes, expand each cylinder and do rotation, and then return to the standard position of checking the hydraulic oil, turn off the engine to check the hydraulic oil amount, if insufficient, it should be supplemented.
Clean and replace the pilot filter element
Open the side cover next to the pump, remove the hose and connector filter, clean the filter with diesel oil, and then install it. Release the pressure inside the hydraulic tank and hydraulic system before operation.
Suggestion: The pilot filter element is removed every 2000 hours and cleaned with diesel oil. If it is not cleaned regularly, the filter element may be blocked or damaged. After impurities enter the pilot oil circuit, gear pump, regulator and other components will wear, abnormal operation and other faults.
