1、裝載機減速器的輸入端旋轉而輸出端不旋轉，或旋轉速度明顯低于正常值這種情況主要原因是，減速器的內部傳動部件出了問題，多為齒輪斷齒或斷軸，此故障只能通過拆檢減速器更換相應零件解決。
The input end of the loader reducer in Shandong is not rotated, or the rotation speed is obviously lower than the normal value. The main reason is that the internal transmission parts of the reducer are a problem, and more than a broken teeth or broken shaft, this fault can only be resolved through the replacement of the corresponding parts of the reducer.

2、裝載機減速器的輸入、輸出端都不能旋轉這種情況的檢修辦法有兩種：一是將輸入端的馬達或電機反轉觀察是否可行，酌情修理或更換，二是拆檢減速器更換相應的零件。
Shandong loader reducer input, output can not rotate the maintenance approach has two kinds: one is to the input side of the motor or motor reverse observation is feasible, as appropriate, repair or replacement, the replacement of the two is the replacement of the corresponding parts.

3、裝載機減速器噪聲和振動明顯高于正常值造成的原因可能是，連接螺栓松動或減速器的有效定位失效，或潤滑油油溫太高、油液太臟。
Shandong loader gear box noise and vibration was significantly higher than that of the normal value of the cause may be, effective positioning connecting bolt looseness or reducer failure, or lubricating oil temperature is too high, oil too dirty.
