Can the gearbox and drive axle lubricants be universal? Kunlun lubrication gives you the correct answer

Changing oil in the daily “big health care” of trucks is an essential step in cleaning up oil and is a necessary means to ensure the normal operation of the truck. Card friends who have been driving for many years will also find that the current trucks transmit more torque than previous trucks, the gears are more, the truck's load weight is also increased, and the requirements for gearbox and transaxle oil are naturally higher than before. high.

The era of buying a large barrel of lubricant gearbox and drive axle has long since passed. In view of the fact that the current transmission and drive axle lubricants are not universal, Kunlun Lubrication has introduced MTF18 long-life manual transmission oil and GL-5+ long-life heavy-duty vehicle gear oil. Next, let Xiaobian take everyone to explore the mystery of these two oils.

Are gears, why is the gearbox and drive axle not universal?

The card friends know that the speed and structure of the manual transmission gear and the transaxle gear are different. Card friends who have bought the corresponding parts probably know that the manual gears are mostly straight or spiral bevel gears, while the drive axle gears are mostly hyperbolic gears. The two gear transmission methods are very different. And the synchronizer in the manual gearbox is mostly made of copper alloy, and the gears in the drive axle are mostly steel alloys.

Different gear oil compositions have different sensitivities to steel and copper. Some oil additives have corrosive effects on materials. Blind use will naturally reduce the service life of each component. What is more serious is that once the gear oil reacts with various parts to produce more oil, it will affect the smoothness of shifting, and the life of the fault will be caused by jumping faults and dislocations.

Why can MTF18 extend the life of manual transmission?

The most common action for card players is shifting. MTF18 manual transmission oil is suitable for all truck manual gearboxes with or without synchronizer, providing more gearboxes for frequent shifting conditions. Good protection, smoother shifting, lower operating temperature of the gearbox, stable and reliable lubrication throughout the 120,000 km oil change interval.

Why is it so emboldened? Just because Kunlun lubrication is the right thing, it is a lot of experimentation. According to Xiaobian, as early as 2007, Kunlun Lubrication developed the MTF18 manual transmission oil, which was not officially launched until August 23, 2018. During this period, a large number of real vehicle tests were carried out, and Kunlun Lubrication was the mainstream car manufacturer on the market. A total of 4 million kilometers of driving tests were carried out in rugged mountains such as Yunguichuan;

1. Under the same slope and vehicle condition, MTF18 manual transmission oil has better heat dissipation and can reduce the temperature of the transmission 20 °C.

2. In the repeated shift test, the number of shifts of MTF18 manual transmission oil is 27% higher than the industry standard.

3. In the thermal oxidation stability experiment, the MTF18 manual transmission oil is 95% higher than the industry standard, which can suppress the formation of sediment to the greatest extent, so that the shifting is always silky smooth.

Why can the GL-5+ extend the life of heavy-duty vehicle drive axles?

From the perspective of the transaxle, it is too easy to "life"! Not only must the power transmitted from the universal transmission be folded through the 90° angle, the direction of force transmission is changed, but the speed is also reduced. The differential is then distributed to the left and right axles and the drive wheels. That work environment and work pressure should be broken in the rhythm of the bones.

GL-5+ long life heavy duty vehicle gear oil

Compared to the ordinary GL-5, GL-5+ high-grade gear oil is fully upgraded in terms of technology, standards and performance. The main upgrades are;

1. Increase the seal strengthening protection to ensure that the drive axle does not leak oil.

2. Increase the pressure and anti-wear strengthening protection to ensure that the teeth are not toothed under heavy load and overload conditions.

3. Increase the high temperature resistant and enhanced protection to maximize the oil change mileage.

If you have to ask how the Kunlun Lubrication is upgraded, Xiaobian can only say that Kunlun Lubrication has a national award. In 2009, Kunlun “Gear anti-wear additive, compound preparation technology and industrial application” won the National Invention Award, and this award is the only national invention award in the whole field. That's right, it's so good!

After reading the three questions of Xiaobian, I completely understood. Not only the gearbox and drive axle lubricants can't be mixed and must be subdivided. If a card friend wants to reduce operating costs, increase economic returns. The next time you give the truck "big health care", you can try "Kunlun Lubrication D12 Long Life Diesel Engine Oil + Kunlun Lubrication MTF18 Long Life Manual Transmission Oil + Kunlun Lubrication GL-5+ Long Life Heavy Duty Vehicle Gear Oil". The 120,000 km long oil change mileage gives you the smoothest long-distance transportation journey.

Maintenance of Sumitomo hydraulic cylinder seals

Daily maintenance and upkeep can effectively solve the sealing problem of hydraulic cylinders, extend the service life of hydraulic cylinders, and improve the work efficiency of construction machinery.
1. Regularly check the wear of the hydraulic cylinder seals, and if severe wear is found, it should be replaced in a timely manner.
2. Clean the hydraulic cylinder seals to prevent impurities such as dust and sand from entering the interior of the seals.
3. Use appropriate hydraulic oil and avoid using expired or non compliant hydraulic oil to avoid damage to the hydraulic cylinder seals.
4. Avoid using hydraulic cylinders under excessive pressure or load to avoid damage to the seals.
5. Regularly check the liquid level and pressure of the hydraulic cylinder to ensure its normal operation and avoid damage to the sealing components due to hydraulic cylinder failures.
6. When the hydraulic cylinder is stopped for a long time, regular maintenance should be carried out, such as applying anti rust oil, to prevent aging or deformation of the sealing components.
