对装载机超越离合器总成进行检查时，应重视装载机解体前各种工况下的工作情况，且只能检查出损坏较大、较严重的故障，而对于其锁紧性能不良但尚能锁紧的故障，在装载机又工作不良的情况下是不能被检查出来的，必须用一定的仪器来检查。

1、装载机http://m.132p.cn/在低速重载作业时，突然出现“咯瞪”的停顿声，继而加油，车又继续前行作业，这是最常见的超越离合器发生故障的早期表现，随着使用时间的延长，这种现象在作业中会越来越频繁地出现，停顿的时间也会相应延长，工作负荷越大，越感到动力不足。
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、装载机平时工作良好，Ⅱ挡行驶正常，但会突然出现工作无力现象。检查时发现装载机变速箱液压油没有变质，油位符合要求且油底滤网没有堵塞，变速压力也正常，这说明超越离合器已损坏失效。
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、装载机以较高速度行驶时，突然在变速箱部位发出较大的机械异响，随即像是被制动似地车速骤减，此时松开油门、停住车，无须摘挡，怠速运转一会儿，异响即消失，然后踏下油门，机车行驶恢复正常。这种现象若不时地出现，这是由于超越离合器的滚柱有发卡现象所致，滚柱本应在不工作位置而现在卡在了工作位置，使原来不参加工作的一级涡轮输出齿轮与超越离合器的外环齿轮间断地工作，致使齿轮发出较大的撞击声，同时产生较大的制动力。
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 、装载机http://m.132p.cn/作业中，挂挡时手感节奏正常，挂挡杆系无松旷现象，变速压力及换挡时的反应也正常，但在起步、换挡时有时机车反应较缓慢。这是因为超越离合器外环齿轮与内环凸轮接合不良、锁死缓慢所致。
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.
