①柴油中有水，水在气缸内蒸发成水蒸气，从排气管排出。
②气缸盖螺栓松动或气缸垫冲坏，使冷却水进入气缸。
③气缸体或气缸盖的某处有沙眼或裂纹，水进入气缸蒸发排出。

6 、挖掘机起动困难或不能起动，排气管大量冒灰白烟的诊断。发动机起动困难，排气管排出大量的灰白烟为柴油蒸气。
① 发动机温度过低，柴油不易蒸发燃烧。
② 喷油器雾化不良
③ 供油时间过晚。
④ 供油量过少，混合气过稀。
⑤ 气缸漏气量过多，压缩终了不能达到着火温度。

　　1、一台挖掘机更换液压油时，应做如下准备：购买整车液压系统用的油。(液压油箱容积的2.5倍)，滤芯，洗油，3公斤面粉，绳子，封闭液压油管的油堵，(按换油的挖掘机上的油管配制)一台汽泵和大小空油桶等。准备一台正常的挖掘机。将换油的挖掘机动臂抬升到高点，斗杆及铲斗收到内点后发动机熄灭(动臂缸，斗杆缸和铲斗缸的缸杆全部伸出到顶点)。

　　2、液压油箱的清洗：将箱内的液压油全部放出，撤出液压滤芯，把泵和油箱之间的管路从泵的接口处拆开，放出管路内的油液。用洗油冲洗液压油箱和管路。用医用沙布把液压油箱内部擦净。将面粉揉和到能拉伸面的程度分成三份，用面团分三次粘干净液压油箱的里面尤其是油箱的边角处和滤芯筒。液压油箱和滤芯筒内清理干净。更换新的液压滤芯，上好盖板。

　　3、液压柱塞泵的冲洗：挖掘机上每种液压柱塞泵都有冲洗油口，(放油口)。拧开上下放油口，放出泵壳内的液压油，拧上泵下面的油堵，从泵上面的油口向泵壳内注满洗油，再拧开泵下面的油堵，放出泵壳内的洗油，反复冲洗几次后，后用汽泵把泵壳内的余油吹干净后，注满洁净的液压油，拧紧油堵即可。

　　4、更换泵进油口密封圈，(O形圈)，将液压油箱连接到泵的供油管路连接好，从液压滤芯油口(放好更换后的滤芯)向液压油箱内注满洁净的液压油。
