Signals Of Failing Clutch

The importance of truck clutch

• It is composed of four parts: the active part, the driven part, the pressing mechanism, and the operating mechanism. The main function of the truck clutch is to gradually engage the engine and the transmission, so as to ensure a smooth start of the truck. As the truck moves from a standstill to driving, its speed should gradually increase from zero. If there is no it between the transmission system and the engine, but a rigid connection, when the truck starts, the driver will engage the transmission of the transmission system into a certain working gear, and the stationary truck will rush forward violently when suddenly connected to the power, generating a large inertial force, resulting in the engine stalling.
• it can also temporarily cut off the connection between the engine and the transmission system, facilitating the start of the engine and smooth gear shifting of the gearbox. When the engine is cold started, let it cut off the connection between the engine and the transmission system, which can remove part of the resistance, which is conducive to increasing the starting speed and improving the starting success rate.

The replacement of the truck clutch

• Under normal circumstances, the replacement cycle of it is about 50,000-60,000 kilometers, but it depends on the driver’s driving habits, if the driver usually does not pay attention to the force when stepping on it, or does not maintain it, the service life of it will be shortened. If well maintained, it needs to be replaced only after the truck travels about 100,000 kilometers.

Signals of failing clutch

Soft or Spongy Clutch Pedal

• One of the first signals you may notice is that your it feels soft or spongy when you press down on it. it is usually quite heavy and usually require some force to press tit pedal, especially on older models or higher-performance trucks. If your pedal becomes very soft than usual when pressed, it may mean that there is a problem with the pressure pads of your clutch and you may need to check the clutch assembly.

Trouble Shifting

• Difficulty in shifting gears is also an important signal of it failure. In the process of truck driving, if you want to change gears, you need to press it in advance, if it plate is too damaged, the power separation cannot be carried out normally, if the power separation is incomplete, pressing it pedal will not help, and the operation of shifting gears or entering a new gear may not be realized.

Burning Smell

• A burning smell is also a signal when the truck it fails. it on the truck is in a tight state during normal driving, if stepping on it for a long time means that it is always engaged, disengaged or semi-slippery, it will accelerate the wear of its friction plate and pressure plate, and wear to a certain extent can easily cause the clutch plate to ablation, resulting in a burning smell.

Noise

• When you press it, if there is harsh noise, then you need to pay attention to it problem. Because of the large number of transmission components on it, the causes of noise are also very complex, including uneven pressure plate, h component damage,  steel sheet breakage, clutch pressure plate spring break or release bearing loosening, clutch release rod breakage, clutch damping spring failure, etc. Therefore, if there is noise after stepping on the clutch, you should go to a professional repair shop as soon as possible to repair it to avoid causing greater problems.

Sticky or Stuck Pedals

• When you find that the pedal is stuck, you can check whether there is a foreign object under it. If there is no foreign object, you should consider whether it fails, because sometimes the control structure of it pedal is too worn, which will cause the stuck phenomenon. And at the same time, also check whether it cable is broken, causing it to stuck.

Ways to use the clutch longer

• Do not step on it for a long time. When stepping on it, the release bearing will rotate at high speed, and the release bearing has no additional lubrication, and can only rely on its internal grease lubrication, once the release bearing wear is excessive, it will plague the pressure plate, and soon there will be starting trembling, stepping on the abnormal it sound, until the final it failure.
• it is mainly used to change gears and start to stop, you should be timely and decisive when changing gears, do not hesitate. When you want to release it in low gears, you should be fast first and then slow, otherwise, it will have a great impact on it and is not conducive to clutch life. At the same time, we should also pay attention, not to semi-linkage, which not only does not have the connection power but also wears a lot on the clutch.
• Every time the truck works, it is necessary to fill its front bearing and the release bearing with butter (some are immersed in oil during disassembly), when filling with butter, do not fill too much, and the amount of oil should be moderate, so as not to enter the friction plate too much, causing it to slip. In use, it is found that the friction plates adhere to oil stains, which will make the clutch slip and should be cleaned. At the same time, according to the requirements of technical maintenance regulations, regularly check and adjust the clutch clearance, once the clutch slippage, incomplete separation and other faults, should be eliminated in time, not allowed to “sick” operation.
• Check the height of it fluid (brake fluid) surface in it reservoir (usually shared with the brake fluid reservoir). If it is below the “MIN” mark, it should be supplemented, and it hydraulic control mechanism should be further checked for leaks. If it fluid splashes on the paint surface, immediately rinse with water; Otherwise, it fluid will damage the painted surface.
