How to change the pilot filter of Sany excavator?
1). Place the boom parallel to the direction of the crawler track, and then stop after turning 45° to the left, so that the bucket cylinder piston rod is fully extended and the bucket rod cylinder piston rod is fully retracted. Slowly lower the boom so that Place the bucket on the ground, then turn off the engine, open the fuel tank bleed valve, pull each operating handle back and forth, and step on the pedal several times to release the residual pressure in the system caused by its own weight.
2). Use gasoline to thoroughly clean the pipe joints, the joints between the pump and the motor, the oil drain plug, the top filler cap and the bottom drain plug of the fuel tank and their surroundings.
3). Open the oil drain valve and the oil drain plug at the bottom of the oil tank, so that all the old oil flows into the oil barrel containing waste oil.
4). Open the refueling cap of the fuel tank, take out the refueling filter , and check whether the residual oil at the bottom of the fuel tank and its edges and corners contains metal powder or other impurities. Clean the fuel tank thoroughly, first clean it twice with diesel fuel, and then blow dry the inside of the tank with compressed air. Check whether there is any residual sludge, impurities, etc. in the internal corners until it is clean, and finally rinse it with new oil.
How to replace the pilot filter of Kobelco excavator?
1. The steps for disassembling the pilot filter are as follows:
1). Park the excavator on a hard and flat ground in the hydraulic oil level checking position. Turn off the engine and place the safety lock lever in the locked position.
2). Clean around the fuel tank cap to prevent foreign matter from falling into the fuel tank. Remove the air exhaust cap and press the hydraulic tank exhaust valve (5-7 times) to release the pressure in the hydraulic oil. Remove the bolts and protective cover on the fuel tank and take out the oil suction filter .
3). Use clean diesel or cleaning agent to clean the oil suction filter. Check the filter after it is completely dry. If there is major damage on the surface, replace it with a new one. Check the two O-rings at the bottom of the oil suction filter . If they are worn, replace them.
4). Install the oil suction filter in sequence, and then install the guard plate. Start the engine and run it at low speed for 5-7 minutes. Extend and retract each cylinder and rotate it. Then return to the standard posture for checking the hydraulic oil. Turn off the engine and check the amount of hydraulic oil. If it is insufficient, add it.
5). How to replace the pilot filter : Release the internal pressure in the hydraulic tank and hydraulic system before starting work. Open the side cover next to the pump, remove the hose and connector filter , clean the filter with diesel fuel and then reinstall it.
