As a common means of transportation, trucks are frequently used. During the use of trucks, various components will inevitably wear out. At this time, maintenance is required to maintain the corresponding functions of each component to ensure that the performance of the truck will not decline. However, in the actual maintenance process, some improper operations will accelerate the decline in truck performance, so truck drivers should understand some taboos in truck maintenance.
Engine oil only added but not changed
Whether it's a car or a truck, when it comes to maintenance, the oil change is always the first thing that comes to mind. Engine oil plays a very important role in the engine and is called the "blood" of the engine. Generally, after driving to a certain mileage, the engine oil will deteriorate, and the engine oil needs to be replaced at this time. But there is another situation where the car needs maintenance before the oil has deteriorated. At this time, it will be checked whether the oil needs to be added. Add engine oil directly to the oil tank every time. Over the years, the deteriorated engine oil is mixed with new engine oil, and the performance will be greatly reduced. At this time, the lubricating, wear-reducing and cooling effects on the engine will be reduced, and the engine will wear more seriously. Therefore, it is still necessary to change the oil regularly.
Tire pressure is too high
The tire pressure of the tire has a great influence on the driving of the truck. During maintenance, not only the degree of wear of the tire should be checked, but also the tire pressure of the tire should be checked. Some drivers think that the higher the tire pressure, the higher the higher, but it is not. If the tire pressure is too high or too low, it will affect the service life of the tire.
The scientific inflation standard should be based on the standard air pressure given by the manufacturer. If there is no special regulation by the car factory, no special adjustment is required in winter or summer. The tire pressure setting is mainly based on the weight of the car body, the height of the chassis, etc. factor.
Butter scribble
Sometimes in order to prevent the nuts from rusting, repairmen will apply butter to the bolts and nuts of truck tires. This practice is actually a loss to the car, and it is also a very unsafe practice. After the tire nut is tightened, the threads have the characteristics of self-locking. After the oil is applied, the equivalent friction angle between the threads decreases, and the self-locking performance of the bolt connection becomes worse. Although this can prevent corrosion, the consequences of nut loosening may be more serious .
When bolts are reassembled, it is a common misconception that the tighter the better, the screw or bolt will break if tightened too tightly. The tightening torque is specified in the manual, so do not change it at will.
Scientific maintenance of the truck can make the service life of the various parts of the vehicle longer, and the attendance rate of the vehicle can be higher.
