[Truck House Original]Vehicle maintenance is a part that every card friend can’t ignore in the process of using the car. Facing the complicated parts market, how to choose the right parts and choose the right parts in the market is a problem that card friends have been struggling with.
In the last issue《Worry-free 200,000 km J6P Replace Gates Belt Set》In the article, we have carried out the loading test of the belt. Today, we will disassemble a domestic belt and a Gates belt to see who is a good accessory worth choosing!
This time, a Gates 8P58 and a domestic brand belt of the same model are disassembled, both of which are suitable for 11 liters of CA6DM2. Maybe some card friends don’t quite understand the naming method of the belt. I will give you a simple science popularization here. The first number 8 represents the number of raised wedges on the multi-wedge belt, PK is the design standard, and 2358 is the length in millimeters.
Put the belt on the ground and observe the back of the belt with naked eyes. Although there is not much difference between the two belts in appearance, it feels that the texture of Gates belt is relatively soft and has the feel of high-quality rubber. The texture of domestic belt is hard, which is somewhat similar to that of plastic.
On the front part, through naked eye observation, it can be found that the surface of Gates belt is rough and the domestic belt is relatively smooth. But why should Gates belt be designed with a rough surface? It is speculated that the rough surface is not easy to slip, and the transmission efficiency is better when driving more powerful accessories.
Compared with the side of the belt, the domestic belt is thicker, and card friends may have a misunderstanding. The thicker the belt, the stronger it is, but it is not. The V-ribbed belt pulley is small, the deformation of the belt is large during operation, and the thicker the belt body, the greater the heat generated.
The thinner belt will generate less heat, thus slowing down the aging of the belt due to long-term high-temperature deformation, helping to increase the life of the belt and saving the later maintenance cost.
It can be heard from the sound of continuous beating to the ground that the domestic belt makes a crisp sound, while Gates’ voice is dull, indicating that Gates’ belt is softer and the materials are more solid. In terms of durability, the long-term operation of the engine will cause wear, and the softer belt will reduce the wear of the belt itself. Even if the belt is aging, good toughness can ensure that the belt will not suddenly break.
By cutting the belt into one, it can be compared that the internal weaving of Gates belt is more meticulous, the fault rubber is arranged neatly, and the internal of the domestic belt is rougher, which makes the work feel relatively cheap.
After the belt is cut open, it can be seen from the cross section that the nylon thread of Gates belt is tightly wound. Although it seems that the domestic brand nylon thread is thicker, it feels that the domestic nylon thread is not tightly wound, giving people a feeling of looseness.
After the surface of Gates belt is peeled off, it can be seen that there is a nylon woven layer under the rubber layer on the surface.
After peeling off the domestic brand, the same nylon woven layer as Gates was not found, so the belt strength will naturally be inferior.
In fact, not only the quality of the belt should meet the requirements, but also the matching tensioner should be paid attention to. In Gates’ accessory maintenance kit, the replacement parts of the tensioner are covered. Gates’ original factory also suggested that card friends should replace the belt together with the tensioner to ensure the matching performance of the accessories.
Don’t underestimate the tensioner, there are many doorways. Gates’ belt tensioner uses NSK bearings from Japan, and the advantages are more obvious with the super performance of Gates’ belt.
Through the actual comparison of the question "Who is the most worthy product", the answer is self-evident. After all, the reason why an international manufacturer like Gates can occupy a place in the market depends on excellent quality and excellent workmanship. Finally, I still advise the card friends that when choosing truck parts, you should never be greedy for cheap, so as to avoid unexpected losses caused by inferior products. (Text/Figure Wu Haochen)
