In the truck's powertrain, the gearbox plays a very important role. How to fully maintain the gearbox is a problem that we cannot ignore.
So what do you need to pay attention to?
Change oil
The quality of the gearbox oil affects the performance of the gearbox, and the gearbox oil needs to be replaced regularly, because the gears mesh with each other and need to transfer huge torque, so gear oil is needed to lubricate and cool the gears. Since most of our trucks are long-distance transportation, we should pay attention to the quality of the transmission oil and replace it in time.
You have to change the oil inside and out
Although the gearbox uses engine oil, it also has problems such as oxidation and deterioration. Since the temperature inside the gearbox is higher than normal temperature, the lubricating oil will be oxidized. When the temperature is high, the viscosity of the lubricating oil decreases and it will become very thin It will also reduce its adsorption capacity, especially for some old vehicles, so it must be checked and maintained in time.
No oil leakage, no oil use
After driving for a certain number of kilometers, it is necessary to check whether the gearbox has oil leakage. Once the oil leakage and oil leakage are found, the cause should be immediately identified and timely repaired.
Because the oil in the gearbox brings the oil at the bottom of the gearbox to the surface of each gear through the gears, the oil can adhere to the surface of the gear to ensure good lubrication between the gears. , It is impossible to splash oil on the surface of each gear through the rotation of the gear.
In this way, the metal surface generates huge heat, it is easy to wear the gear surface, and in severe cases, the gear will be burned, making it impossible to rotate!
