Pouring liquid lubricant into the gears of a big truck helps reduce friction between the moving components, allowing the gears to shift smoothly and operate efficiently. It minimizes wear and tear on the gear teeth, prevents overheating by dissipating heat, and protects against rust and corrosion. Proper lubrication is essential for extending the lifespan of the truck's transmission and ensuring reliable performance, especially under heavy loads and long-distance driving conditions. | Asian Tech
