The efficient operation of commercial trucks significantly depends on the right choice of lubricants. These are critical for reducing friction, preventing wear and tear, and extending the lifespan of various truck components. Here are some types of lubricants you should know about when it comes to commercial truck maintenance.
Engine oil is paramount to the smooth operation of a truck. Its role is to lubricate the engine's moving parts, reducing friction and heat. It also prevents corrosion and helps to keep the engine clean by minimizing the buildup of sludge and debris. There are three main types of engine oils: synthetic, semi-synthetic, and mineral oil. Synthetic oils are chemically engineered for improved performance and offer superior protection and efficiency, especially in extreme temperatures.
Transmission fluid is essential for the operation of a truck's transmission system. It lubricates gears, clutches, and valves, facilitates gear shifts, cools the transmission, and protects against corrosion. The type of transmission fluid required can depend on the make and model of the truck, with some requiring specific formulations.
Brake fluid is a type of hydraulic fluid responsible for transmitting force in a truck's brake system. It should be resistant to heat since the braking process generates substantial temperatures. This fluid is also tasked with protecting the braking system's metal components from corrosion.
Coolant, or antifreeze, is a heat transfer fluid that absorbs heat from the engine and dissipates it through the radiator. It prevents the engine from overheating in high temperatures and from freezing in cold temperatures. Antifreeze also inhibits corrosion within the cooling system.
Gear oil is used to lubricate the gears in the differential and manual transmissions. It is thicker than engine oil to withstand high-pressure conditions without breaking down. Gear oil also helps protect against wear and rust.
Commercial truck lubrication isn't complete without a good understanding of grease. Grease is unique because it's not a fluid like the other lubricants mentioned earlier. Rather, it's a semi-solid lubricant that consists of a thickening agent mixed with a base oil.
A key advantage of grease is that it stays in place under heavy loads, making it ideal for lubricating areas where oils would simply drain away, such as wheel bearings and chassis. It forms a protective layer that reduces wear by preventing direct metal-to-metal contact.
It's also excellent at sealing out contaminants and moisture, hence safeguarding against rust and corrosion.
Used in trucks with hydraulic systems, such as dump trucks and garbage trucks, hydraulic fluid transfers power within the system. It also lubricates the system's components, reduces wear, and protects against rust and corrosion.
