1、雖然機器還可以工作，但變速器內的油液早已變質，粘度下降并含有金屬雜質，因此應在推薦的換油間隔期以前更加頻繁地分析變速器的油樣。因為離合器磨損是變速器故障擴大的標志，如果金屬雜質進人齒輪副或卡住齒輪使其不能對中，若再不停機就會研碎變速器中的其他構件。
Although the machine can also work, but already within the transmission oil deterioration, decreased viscosity and contains metal impurities, and therefore should be more frequent transmission oil sample analysis in the recommended oil change interval before. Because clutch wear is a sign of the expansion of transmission failure, if the metal impurities into gear pair or stuck in gear so that it can not be right if he did not stop the transmission will crush the other components.
2、換擋性能下降是離合器損壞的征兆。離合器開始打滑時，即使平穩加速，機器也會向前沖，此時應停機檢修。
Shift clutch performance degradation is a sign of damage. When the clutch started slipping, even smooth acceleration, the machine will forward, at this time should be shut down for maintenance.
3、離合器操縱油位下降，當機器必須加速才能使離合器接合時，就說明離合器已出現過度磨損或密封失效現象。因此，測量變速器的油壓和觀察油溫是否上升就可判定離合器的磨損情況。與此同時還應分析油質，若油液中出現鐵或鉻的微粒，則表明齒輪副已開始磨損。
Clutch operating oil level drops, when the machine must be accelerated in order to make the clutch is engaged, the clutch has appeared on shows excessive wear or seal failure phenomenon.Therefore, the measurement of the transmission hydraulic oil temperature is observed to rise and it is determined that the wear of the clutch. At the same time should also analyze the oil, if iron or chromium particles appear in the oil, then the gear pair has begun to wear.
