1、首先要看装载机变速箱压力，如果压力不足，比如在1以下，那么你就在通过加操纵阀调整垫来加压，建设是换件来测试。
First look at Shandong loader gearbox pressure, if the pressure is not enough, for example, in one of the following, then you are in control valve to adjust the cushion by adding to the pressure, the building is for parts to test.

2、如果上述情况是好的，压力好，变速箱好，那就把山东装载机变速箱的滤油器拆掉不要滤芯试一下，把变速箱底壳的滤芯也拆掉试一下。
If the above conditions are good, the pressure is good, the gearbox is good, then the Shandong loader gearbox oil filter cartridges do not try to tear down, to the bottom shell of the filter also removed the gearbox try.

3、如果压力是好的，正常的，换山东装载机变速泵，记得进油管的螺栓一定要扭紧。
If the pressure is good, normal, for Shandong loader variable speed pump, remember inlet pipe must tighten bolts.

4、装载机发动机的输出动力也是很关键的，变速箱也一样动力不足，建议把喷油泵去校一下。
Shandong loader engine power output is also very critical, gearbox too underpowered, it is recommended to go to school at the fuel pump.
