對裝載機超越離合器總成進行檢查時，應重視裝載機解體前各種工況下的工作情況，且只能檢查出損壞較大、較嚴重的故障，而對于其鎖緊性能不良但尚能鎖緊的故障，在裝載機又工作不良的情況下是不能被檢查出來的，必須用一定的儀器來檢查。

1、裝載機http://m.greennutrition.cn/在低速重載作業時，突然出現“咯瞪”的停頓聲，繼而加油，車又繼續前行作業，這是最常見的超越離合器發生故障的早期表現，隨著使用時間的延長，這種現象在作業中會越來越頻繁地出現，停頓的時間也會相應延長，工作負荷越大，越感到動力不足。
When low-speed heavy loader work, the sudden appearance of "thump" sound pause, then refuel the car and move operations, which is an early manifestation of the most common clutch failure, with the use of time, this phenomenon will occur more and more frequently in the job, the pause time will be extended, the greater the workload, the more we feel underpowered.

2、裝載機平時工作良好，Ⅱ擋行駛正常，但會突然出現工作無力現象。檢查時發現裝載機變速箱液壓油沒有變質，油位符合要求且油底濾網沒有堵塞，變速壓力也正常，這說明超越離合器已損壞失效。
Loader usually work well, Ⅱ block traffic to normal, but the phenomenon of sudden inability to work. Examination found no deterioration loader gearbox hydraulic oil, the oil level in line with the requirements of the end of the filter and the oil does not clog, shifting the pressure is also normal, indicating that the failure has been damaged clutch.

3、裝載機以較高速度行駛時，突然在變速箱部位發出較大的機械異響，隨即像是被制動似地車速驟減，此時松開油門、停住車，無須摘擋，怠速運轉一會兒，異響即消失，然后踏下油門，機車行駛恢復正常。這種現象若不時地出現，這是由于超越離合器的滾柱有發卡現象所致，滾柱本應在不工作位置而現在卡在了工作位置，使原來不參加工作的一級渦輪輸出齒輪與超越離合器的外環齒輪間斷地工作，致使齒輪發出較大的撞擊聲，同時產生較大的制動力。
When the loader to travel at higher speeds, suddenly emitted a large mechanical parts in the gearbox abnormal sound, then plummeted like a vehicle is braked wildly, then release the accelerator, the car stopped, no pick-speed, idling while, abnormal sound disappears, then depress the throttle, locomotive traveling back to normal. If this phenomenon occurs when the ground, which is due to overrunning clutch rollers have hairpin phenomenon caused by the rollers in the inoperative position should now stuck in the working position, so that the original does not participate in the work and a turbine output gear beyond the outer ring gear clutch work intermittently, resulting in a larger gear issued crash, while a greater braking force.

4 、裝載機http://m.greennutrition.cn/作業中，掛擋時手感節奏正常，掛擋桿系無松曠現象，變速壓力及換擋時的反應也正常，但在起步、換擋時有時機車反應較緩慢。這是因為超越離合器外環齒輪與內環凸輪接合不良、鎖死緩慢所致。
Loader operations, when Guadang feel normal rhythm, no Songkuang phenomenon linked lever system, the stress response and shift speed when it is normal, but in the beginning, when the shift reaction is sometimes slow locomotive. This is because the clutch outer and inner cam gear engages bad, lock slow due.
