What to do if the excavator leaks oil
Two program references
Option One
1. Remove the steel pipe and check the joint of the steel pipe to see if there are flash / burrs in the oil seal groove. These will directly lead to the damage of the oil seal; if so, you can find a manufacturer and let them change the steel pipe for you.
2. Use a regular oil seal, pay attention not to choose the wrong oil seal model, it is best to use original accessories;
3. Do not use too much force when tightening the joint after changing the oil seal. It is best to call the manufacturer's service personnel to tighten with a fixed torque wrench (the tightening of the joint of the hydraulic pipeline is required by torque)
Option II
First clean the oil leakage surface with toilet paper or a rag, find the point of oil leakage, and check whether the oil leakage at the interface is caused by the broken oil pipe. If the oil pipe is broken, remove it and take it to the place where the pressure oil pipe is found, and replace it directly; if it is the interface, it is likely that the oil seal is broken. Find the oil seal package of this series of excavators and replace it. It should be noted that the inspection needs to be started after the replacement, to ensure that there is no oil leakage before continuing work.
Over 90% of oil leakage is caused by the aging of oil seal corrosion. Especially for cars over three years old. Because the rubber seal is affected by the alternating temperature changes for a long time, it will lose the plasticizer. The consequence is that the seal shrinks, hardens, loses its elasticity, and even breaks (this is far from being reached. When oil leaks, maintenance Will find), the problem of oil leakage is inevitable.
This issue is not recommended for repairs and repairs, which can range from hundreds to thousands or even tens of thousands at a time. But it may not solve the problem and hurt the car. It is recommended that car owners and friends use the "free disassembly to solve car oil leakage" method, and do not disassemble to solve car problems.
