The maintenance cycle of ground screws mainly depends on their material and usage environment. The maintenance cycle of ground screws of different materials is different:
Iron screws: Since iron screws are prone to rust, it is recommended to replace them every 1 to 2 years, or every 20,000 kilometers.
Stainless steel screws: Due to their excellent corrosion resistance, the maintenance cycle can be extended to 3 to 5 years.
Aluminum screws: Due to their light weight and corrosion resistance, the maintenance cycle can be further extended to 5 to 7 years.
In addition, the maintenance cycle is also affected by environmental factors. In areas with high humidity or heavy salt, the corrosion rate of screws will accelerate, so more frequent inspection and replacement are required. In harsh road conditions, screws wear faster and the need for replacement will increase.
Maintenance steps include:
Loosen the screws in a safe state.
Drain the oil and remove the old sealant.
Apply new sealant and tighten according to the torque recommended by the manufacturer.
Through regular inspection and maintenance, the stability and reliability of the ground screws can be ensured, oil leakage can be avoided, and the normal operation of the engine can be ensured.
