The clutch master cylinder is located near the clutch pedal motor outlet.

It is a very simple hydraulic cylinder that is connected to the clutch pedal of our vehicle and to the impeller of this pedal by a hose full of oil.

As a hydraulic clutch, the clutch master cylinder is a complex system, but it is often easy to find the cause of its failure.

What is clutch master cylinder (clutch pump) and how does it work ?

The clutch master cylinder, or called clutch pump (upper clutch cylinder) is the main type of hydraulic clutch operating system. This simple hydraulic principle is used to transmit the required force from the clutch pedal to the slave cylinder (lower clutch cylinder).

This part of the clutch system is connected on one side to the clutch pedal via a lever mechanism. The other end is connected via a hose to the slave cylinder, which moves the clutch.

When to change the clutch master cylinder ?

The clutch master cylinder is a component that allows us to manipulate the clutch pedal correctly, always with less effort than we would need if this part were not present in our vehicle.

Like other components of the clutch system, the clutch master cylinder can exhibit very characteristic faults. It is therefore very important to be aware of all of them.

Depending on the vehicle model, repairing the clutch master cylinder is usually quite simple, as well as inexpensive.

On some car models all that is required is to purchase a new clutch master cylinder assembly, unscrew the clutch line, then remove the component retaining bracket, replace the new clutch pump or clutch master cylinder buy from after market.

Here, KOMP explain when it is necessary to repair the clutch pump of our vehicle or when to do the clutch master cylinder replacement:

When the pedal is stuck

This first symptom occurs when the clutch pedal of our vehicle is depressed, the clutch pedal goes down, but does not return to its initial position. If this happens, we cannot change gears, so we will have to stop our car until we replace the clutch master cylinder with a new one.

Hardly any brake fluid

In the reservoir where the brake fluid is located, we can see some marks on the side that indicate the amount we have in the reservoir. If the brake fluid is below the mark, it is important to top it up. Depending on the vehicle model, one type of fluid or another will be necessary.

But why does the brake fluid diminish? Over time, the clutch master cylinder or clutch pump loses brake fluid due to a possible leak in the master or slave cylinder of the clutch system.

Gear shifting is too jerky

When the clutch master cylinder is damaged, but we can continue to drive, this may be due to the fact that gear change is too abrupt during driving. As a result, the clutch may start to slip. It is important to press the clutch pedal firmly and consciously, but not violently.

When the pedal is soft or spongy

If at any point in your driving you notice that the clutch pedal is lighter and easier to depress than before, this is another symptom that indicates that the clutch pedal should be replaced. This is because the clutch master cylinder has air in it, so the pedal starts to feel softer.

Brake fluid is dark

The last indicator that may alert us to check our vehicle's clutch pump is if the brake fluid we have replenished suddenly becomes very dark.

This may be because one of the internal seals in the clutch master cylinder is failing. Rubber debris from these internal seals can break down with use and contaminate the fluid, thus discolouring the contents of our car’s reservoir.

However, if the brake fluid has not been changed recently, it is necessary to consult the owner’s manual of your car to find out the recommended maintenance interval.

To avoid clutch master cylinder or clutch pump wear, at KOMP, we have a wide range of clutch master cylinder for various different types of cars and trucks on the market.

In addition, we have a Development Department that is constantly creating new brake parts for new models.

Forged steel products are known for their unique characteristics and advantages over other manufacturing methods. Here are some key characteristics of forged steel products:

Strength and Durability: Forged steel products exhibit exceptional strength and durability. The forging process involves applying compressive forces to shape the metal, resulting in refined grain structure and improved mechanical properties. This makes forged steel products highly resistant to impact, fatigue, and wear, making them suitable for demanding applications that require strength and long-term reliability.

Improved Metallurgical Properties: Through the forging process, the internal grain structure of the steel is aligned, which enhances the mechanical properties of the material. It improves the toughness, tensile strength, and overall structural integrity of the product. The controlled heating and cooling during forging also allow for the removal of impurities, resulting in a cleaner and more homogeneous material.

Customizability: Forged steel products offer excellent customizability in terms of size, shape, and design. The forging process allows complex shapes and intricate details to be formed accurately, providing versatility in creating components for various industries. Customized forged products can be tailored to meet specific performance requirements and integrate seamlessly into existing systems or machinery.

Good Fatigue Resistance: Due to the refined grain structure and aligned fibers, forged steel products exhibit superior fatigue resistance. They can withstand repeated loading and high-stress conditions without experiencing premature failure. This makes forged steel components suitable for applications where cyclic loading or dynamic forces are involved, such as automotive parts, machinery components, and aircraft landing gears.

Improved Material Integrity: Forged steel products have a higher level of material integrity compared to cast or machined parts. During the forging process, the superior metallurgical properties enable the steel to maintain its chemical composition and mechanical properties consistently throughout the product. This results in a product with fewer defects, such as voids, porosity, or inclusions, which can weaken the material and compromise its performance.

Cost-Effectiveness: While the initial production costs of forging may be higher compared to other manufacturing processes, forged steel products often offer long-term cost savings. Their durability and resistance to wear and deformation reduce the need for frequent replacements and maintenance. Additionally, the superior mechanical properties can result in improved performance and efficiency, contributing to overall cost-effectiveness.

Overall, forged steel products are valued for their strength, durability, customizability, fatigue resistance, material integrity, and cost-effectiveness. These characteristics make them preferred options for demanding applications, where reliability and performance under extreme conditions are crucial.

Compared with the casting, the shell body of the forged idler has a more uniform structure, better density, better strength integrity, better dimensional characteristics, and smaller dimensional error. The directional structure has higher performance in overall strength and application capability than the casting.



High Strength



Hot forging promotes the refinement of crystallization and grain, maximizing the material strength and consistency and reducing variation between forgings. The granular flow precisely flows along the shell body contour. These continuous streamlines are conducive to reducing the incidence of fatigue or common failures.



The Reliability



One of the most important advantages of forgings is that they can meet the requirements of the designed structure.



The Structural Integrity



Forging eliminates internal flaws and produces a coherent and uniform metallurgical structure assuring optimum performance. Where stress and corrosion problems of crystals are serious, forgings can ensure long service life and problems free service.



The Uniformity



The application of rolling forging technology makes the uniformity of the front Idler dimension. Dimensional uniformity of closed-die forging results in positive control of critical wall thickness, eliminating deficiencies caused by shifted core in castings. High quality and no separation of steel ingot can eliminate internal flaws and produce a coherent and uniform metallurgical structure. The fatigue strength of creep is three times higher than that of casting.

Now more and more new technologies used in Excavator and Bulldozer spare parts manufacture, for example: the friction welding. It has been used in track roller for many years and we are a expert in this area.

Friction welding is a solid-state joining process, which could achieve reliable solder joints and create high-quality, high-strength joints with low distortion. These prolong the working life of the track rollers.

The friction welding track roller has many advantages. In friction welding, the welding allowance of the weldment and the welding power are small, the assembly requirements of the weld are not high, and the electric energy is saved, it is environmentally friendly. Because of high productivity and good quality, it has been widely applied in track roller manufacture.

Why does the friction-welding track roller be better in the wear-resistance and have a longer working lifetime?

Firstly, consumption of raw material: the roller bodies of traditional track roller are connected by the welding rod. but the friction ones are connected by the friction between rollers bodies. So the friction-welding roller will be added more raw material to make sure the roller is perfect to the standard size after welding.

Secondly, inner parts: For the traditional rollers, the welding is done after two processes of maching, so the size of the inner parts are not so precise as friction-welding ones. For the fricion-welding ones, after the weilding, there is one more precise maching with concentric locating to make sure the conformity of inner size,this means the inner parts are more precise with higher standard.

We believe in that there will be more and more new advanced technologies used in Excavator and Bulldozer spare parts manufacture in the future. Our parts will be more stable and have a longer working life. Our durable parts make it possible for your machines to deliver the performance you demand. Protect your investment by always choosing our genuine parts.

Undercarriage parts have a huge effect on working performance and walking performance of excavator. Maintenance is a key to walking speed of excavator. How to maintain your “undercarriage parts”? There are some tips as following.



1. Carrier Roller is above the track frame. The function is to carry and keep the track moving in a straight line. If Carrier Roller has a breakdown, Track Link will not work properly. Carrier Roller is added lubricating oil at once. If oil spills occur, you will have to replace this part. Therefore, you should keep the track frame clean. Don’t let the accumulation of dirt and gravel hamper its work.



2. Front Idler is in the front of the track frame. The function is to prop the track up and guide the track to wind correctly. Besides, Front Idler and Track Adjuster work together to maintain a certain degree of tension on the track. So during working and walking, should keep Front Idler running ahead, which can avoid the wear of the track. Meanwhile, Track Adjuster can reduce the vibration and shedding of the track during walking.

4. During working, Track Roller can’t be immersed in mud for a long time. After working, should support the track on one side. Then, Drive walking motor to get rid of dirt and gravel. In winter, should keep Track Roller dry because there is a floating seal between the outer roller of Track Roller and the shaft. If there is water, it will freeze at night. When the excavator is walking the next day, the floating seal is in contact with ice to cause oil spill. When Track roller is damaged, can cause many faults, such as walking deviation, walking weakness and so on.

5. The track motor guard can protect the motor. However, the dirt and gravel also can enter the interior, which making the oil tube of the motor wear out. Moisture in the dirt will corrode the joint of the oil tube, so regularly open the guard and clean up the dirt inside.
