Netizen a said: leave the bearing is not worn out and lack of oil, ask the repairman to put some butter in and try again.

　　网友B说：吹一下压盘，可能尘土太多。

　　Netizen B said: blow the pressure plate, there may be too much dust.

　　这样处理对不对呢，当然我们还有更的解释，请渐渐往下看：

　　Is this right? Of course, we have a more professional explanation. Please look down gradually:

　　离合器感到重的缘由较多，如搅拌车离合器本身特性、离合器拉线磨损、别离轴承和轴承座上抹黄油招致阻力增大、离合器片变薄等。下面是针对各个缘由停止的剖析：

　　There are many reasons for the clutch to feel heavy, such as the characteristics of the mixer clutch itself, the wear of the clutch cable, the increase of resistance caused by the application of grease on the separated bearing and bearing seat, and the thinning of the clutch plate, etc. The following is an analysis of the reasons for the stop:

　　1、可能是搅拌车离合器本身特性

　　1. It may be the characteristics of the mixer clutch itself

　　踩离合器时的阻力主要来自压盘膜片弹簧，由于需求把膜片弹簧压下去才干使离合器别离，有些车压盘大，膜片弹簧弹力强，离合器肯定更重。有些车压盘小，膜片弹簧弹力小，离合器更轻。这是先天缘由，但也不是没有办法改动，能够改换变速箱端离合器驱动摇臂，摇臂越长力臂越大，踩离合越省力。

　　The resistance when stepping on the clutch mainly comes from the diaphragm spring of the pressure plate. Only when the diaphragm spring is pressed down can the clutch be separated. Some cars have large pressure plate, strong spring force of the diaphragm spring, and the clutch must be heavier. Some cars have small pressure plate, small diaphragm spring force and lighter clutch. This is a congenital reason, but it is not impossible to change. It can change the transmission end clutch driving rocker arm. The longer the rocker arm is, the larger the force arm is, and the less effort is required to step on the clutch.
                

　　2、可能是离合器拉线磨损

　　2. Maybe the clutch cable is worn

　　离合器拉线外面是硬管，里面是一层尼龙套管，再往里面就是钢索，运用时间长了尼龙套管磨损严重招致钢索嵌入套管里，摩擦力增加，这时分加光滑油根本没太大效果，离合器踏板的阻力根本上是成倍增加的。

　　The outside of the clutch cable is a hard pipe, the inside is a layer of nylon sleeve, and then the inside is a steel cable. The wear of nylon sleeve after a long time of use causes the steel cable to be embedded in the sleeve, and the friction force increases. At this time, the effect of adding smooth oil is not great at all, and the resistance of the clutch pedal is multiplied.

　　3、别离轴承和轴承座上抹黄油招致阻力增大

　　3. Increase of resistance caused by grease applied on separated bearing and bearing seat

　　踩离合时分别离轴承会在轴承座上前后挪动，有些人觉得给这里抹光滑油或黄油能够避免磨损，其实这样做很容易招致离合器变重。由于黄油自身就有阻力，特别是关于别离轴承和轴承座这种滑动摩擦部件来说阻力更大。离合器运用中也会产生一些粉尘，被光滑油或黄油吸附后会招致阻力进一步增大。

　　When stepping on the clutch, the bearings will move back and forth on the bearing seat. Some people think that smearing smooth oil or grease here can avoid wear. In fact, doing so can easily lead to heavy clutch. Since the grease has its own resistance, especially for the sliding friction parts such as the separated bearing and bearing seat, the resistance is greater. Some dust will also be produced in the application of clutch, which will lead to further increase of resistance after being absorbed by smooth oil or butter.

　　4、离合器片变薄

　　4. Thin clutch plate

　　离合器片变薄后压盘摩擦面在膜片弹簧作用下会继续向前压紧来补偿这局部间隔以保证离合器可以有足够的压紧力，这时分膜片弹簧会继续向上翘起，招致别离轴承与膜片弹簧接触面受力角度发作改动，这时需求用更大的力才干压动膜片弹簧。

　　After the clutch plate becomes thinner, the friction surface of the pressure plate will continue to press forward under the action of the diaphragm spring to compensate for the local space to ensure that the clutch can have sufficient pressing force. At this time, the diaphragm spring will continue to rise up, causing the force angle of the contact surface between the separated bearing and the diaphragm spring to change. At this time, it needs to use more force to press the diaphragm spring.

　　友谊提示：离合器压片、离合器压盘或者别离轴承，是我们通常所说的“离合器三件套”，这些零部件都是耗费件，假如存在磨损严重的状况，在改换的时分更好全部改换。

　　Friendship tip: clutch pressure plate, clutch pressure plate or separated bearing are what we usually call "three piece clutch set". These parts are all expendable parts. If there is serious wear, it is better to replace them all when replacing them.
