Four Kinds Of Lubricating Oils Required By Sinotruk HOWO Truck
Lubricating oil is needed for friction of any mechanical part. Sinotruk HOWO truck generally need four types of lubricating oil: engine oil, brake oil, steering oil and grease. Today, we will introduce the functions of these lubricating oils and the correct replacement methods and positions.
Adding engine oil to SINOTRUK HOWO truck
Engine oil is the most familiar one. As we all know, the engine is the “heart” of HOWO trucks and the most core part of automobiles. Engine oil is often compared to the “blood” of trucks.
After sinotruk HOWO truck is started, there is rapid friction between piston and cylinder and between main shaft and bearing bush. One of the major functions of oil is to form oil film between two friction surfaces through part friction. The oil film will separate the surfaces of two friction parts, so as to reduce wear. We should develop the habit of changing the engine oil regularly. It is suggested that the replacement cycle is every 5000 km of your HOWO truck.
During the daily maintenance of HOWO trucks, many riders know that it is necessary to check the wear of brake pads and brake discs. Here, I would like to emphasize to all riders that there is another important role in the brake system that needs maintenance – brake oil!
Brake oil is also called brake fluid. Brake oil plays a transmission role in the automobile brake system. If there is a problem with the brake oil, the braking effect is bound to be greatly reduced, and sometimes even the brake fails.
Generally, it is recommended to change the brake oil every two years or when the mileage reaches about 40000 km. However, according to the different conditions of SINOTRUK HOWO trucks, specific judgment is required.
Grease and lubricating oil are used for the friction parts of machinery to lubricate and seal. It is also used on metal surfaces to fill gaps and prevent rust. The alias of lubricating grease is “butter”, which is mainly composed of mineral oil (or synthetic lubricating oil) and thickener. The semi-solid form of lubricating grease enables it to protect parts and components at all times, so the sealing effect and protection effect of lubricating grease are better than that of lubricating oil. The parts on HOWO trucks that should not use liquid lubricant, such as hub bearing, ball joints of each pull rod, engine, water pump, clutch bearing, etc., all use grease.
When driving, you may think that the steering wheel of SINOTRUK HOWO truck is getting heavier and heavier? This phenomenon is most likely caused by a problem with the “steering oil”.
Steering oil is a special oil used in the truck power steering pump. Through the hydraulic action, the steering wheel can be lightened, which is similar to the automatic transmission oil and brake oil. Steering oil can not be ignored in vehicle maintenance. If the steering oil is not changed for a long time, the steering wheel will feel heavy, affecting the driving experience and increasing the fatigue of the owners.
The steering oil required by different models is different, so it is best to add it according to the type of steering oil indicated in the vehicle manual. The automatic transmission oil for individual trucks can also be used as steering oil. The steering oil of SINOTRUK HOWO truck is recommended to be completely changed once a year or 20000 km.
The oil replacement cycle required by different parts of HOWO trucks is also different. All motorists should follow the operation manual of SINOTRUK HOWO trucks and take care of their vehicles on time. At the same time, selecting a suitable oil for your car can add vitality to your car.
