Maintenance Precautions for Automotive Drive Shafts and Idler Wheels

The car is about 40,000 kilometers every two years: At this time, the vehicle has already gone through a run-in period and all parts of the vehicle are fully active. This is the peak period of the vehicle, but some of the closed loop oils and liquids are almost replaced at this time, known as the "great maintenance."

Brake oil has very strong moisture absorption, so it is best to replace it every 40,000 kilometers to ensure its normal function. Mars plugs can be replaced almost as well. In order to maintain the cooling effect of its engine, the water in the tank can be replaced at this time to prevent scale accumulation from obstructing circulation, and appropriate tank fines can be added. At the same time, once every two years to do a tire position for the vehicle, of course, when you change the tire to do positioning.

The car is about 7 to 80,000 kilometers every 4 years: At this time, some parts of the vehicle gradually show signs of aging, but there is no need to worry. As long as the maintenance is timely, these parts can still maintain good condition after the update. The life of the drive shaft boot is about 4 years. If the boot of the drive shaft is broken, it will easily cause the wear of the universal joint, which will cause the front wheel noise during cornering. If the wear is serious, the entire drive shaft needs to be replaced. . It is advisable to inspect and check if it is damaged every five thousand kilometers. As long as the idler belt is cracked or too loose, it should be replaced. The belt will wear with a sharp friction sound and will become higher as the engine speed increases. It is easy to self-identify. In addition, there is an aging problem with rubber cushions on the engine's feet. The most obvious effect of this small thing's failure is engine jitter. The service life of the engine timing belt is almost the same, and every week, maintenance technicians can pay attention to the situation every 5000 km.

In order to ensure the normal operation of the drive shaft and extend its service life, attention should be paid in use:
1. It is forbidden for cars to start with high gears.
2. Do not slam the clutch pedal.
3. It is forbidden to overload and speed the car.
4. Always check the drive shaft operating conditions.
5. The tightening condition of the propeller shaft hanger should be checked frequently, and whether the supporting rubber is damaged, whether the connecting parts of the driving shaft are loose and whether the driving shaft is deformed.
6. In order to ensure the dynamic balance of the drive shaft, attention should always be paid to whether or not the welding lug is to be welded off. The new driveshaft assembly is provided as an accessory. When installing the new driveshaft, attention should be paid to the assembly mark of the telescopic cover. The flange fork should be in a plane. When disassembling the drive shaft during maintenance, the assembly marks should be printed on the expansion sleeve and the flange shaft in order to keep the original assembly relationship unchanged during reassembly.
7. You should always add grease to the universal joint cross bearing. In the summer, you should inject the No. 3 lithium grease, and in the winter, inject the No. 2 lithium grease.
