装载机http://www.sdyongbaojixie.com/散热器中的冷却液上漂浮着一层油液，但检查油底壳机油时未发现有水，用水从冷却液上沾取少许油液，通过闻气味和观察颜色判定为机油，由此排除了液力传动油散热器漏油的可能性。那么导致这种问题的原因是什么呢？
Loaders radiator coolant floating layer of oil, but have not found the time to check the oil sump water, the water picks up a little oil from the coolant through smell the smell and observe the color of the oil is determined by this ruled out the possibility of leakage of hydraulic transmission oil cooler. So the cause of this problem, what is it?
　　
装载机柴油机的风扇和水泵是同轴转动，为了消除水泵的影响，拆除了风扇胶带，启动柴油机，从水箱盖孔发现冷却液剧烈翻滚，因漏油来自机油散热器，说明故障部位必然出在气缸盖或气缸套部分。此时可以拆下某一缸的喷油器，使其气缸与大气相通，启动柴油机并观察，若此时散热器里的冷却液不再剧烈翻滚，则可判定该缸即为故障缸。
Loader diesel engine fan and water pump are coaxial rotation, in order to eliminate the influence of the pump, remove the fan belt, start the engine, radiator cap from the coolant hole found dramatic tumble, because the oil spill from the oil cooler, indicating the fault lies in the inevitable parts part of the cylinder head or cylinder liner. At this point you can remove a cylinder injector to the cylinder and the atmosphere, start the engine and to observe, if at this time the radiator coolant no longer violent roll, it is judged that the cylinder is the failed cylinder.
　
由于装载机http://www.sdyongbaojixie.com/的柴油机采用的是PT型燃油泵，当拆下其一个喷油器后，其他各缸将不能正常工作，因此也就无法进行故障判断。为此，找到一个报废的该机型的喷油器，先拆下其油杯、柱塞和挺杆等，并将其进油口的回油口堵住，然后将该喷油器体作为专用工具安装到气缸盖上，这样，既可使低压供油系统畅通，又能使气缸内气体与大气相通。
Because diesel is used loaders PT type fuel pump, remove it when a fuel injector, all other cylinders will not work and, therefore, can not fail to judge. To do this, find a scrap of the models injector, first remove its oil cup plunger and tappet etc., and the inlet of the oil return port is blocked, then the injector body as special tools to install the cylinder head, so that it can enable the low-pressure fuel system flow, but also make the cylinder gas atmosphere.
