The drive belt is tight. If the transmission belt is adjusted too tightly, it is easy to stretch and deform, and the pulley and bearing are easy to cause bending and damage.
For both veteran and novice drivers of semi-trailers, semi-trailer maintenance is prone to some errors due to empiricism or dogmatism, so that semi-trailers have accidents during driving or the maintenance effect is not ideal. In fact, for car owners, they still need to be careful when maintaining the bolts, belts, and oil, so as not to enter the maintenance misunderstanding.
Misunderstanding 1
Tighten the bolts. There are many fasteners connected with bolts and nuts on the semi-trailer, and it should be ensured that they have sufficient pre-tightening force, but they should not be over-tightened. If it is over-tightened, the bolts and connectors will be deformed, and the pre-tightening force will decrease, and even cause the phenomenon of slipping or breaking.
Misunderstanding 2
The drive belt is tight. If the transmission belt is adjusted too tightly, it is easy to stretch and deform, and the pulley and bearing are easy to cause bending and damage.
Misunderstanding three
How good is the oil. If there is too much oil, the crankshaft handle and connecting rod will be violently stirred when the engine is working, which will not only increase the internal power loss of the engine, but also cause the oil to burn out due to the increase of oil splashed on the cylinder wall.
In addition, when going to a maintenance point or a 4S shop for maintenance, the owner should try his best to choose a maintenance master who has a relatively good understanding of his model, which can not only save the time for re-testing, but also avoid wrong judgments caused by unfamiliarity. Of course, for a master who has been in contact with a car for a long time, there may be some errors based on experience, but in general, the more familiar maintenance masters still have more advantages than disadvantages.
