日立240挖掘机斗竿油缸要换油封,缸盖及活塞怎么拆装
推荐回答(1个)
其实第一次自己维修觉得很难 其实很简单 就是怎么拆再怎么装 一定要记得先后顺序 下每个零件之前你就要做好思想准备 记好每一步 最先拆的要最后装 就是拆和装的时候顺序反过来了 你要想学就自己动手实践 别人再说你到实际操作时还是发糊涂的 只有自己先做 反正做好了就学到技术 实在不会了 不是还有专业的吗 请来请他装 你在一旁看着 多留意 下次你保证就会了 这些换油封的很简单的 但是发动机之类的还是请专业的 因为那个装的不好不是开玩笑的 简单的维修 就自己动手做 东西都是人造出来的 反正我就是这样干的 哪怕第一次做不好 第二次只会更好 学会了 技术就是自己的了
