What if the oil leakage can't be eliminated?
It is very simple. The electric butterfly valve can be pulled out to further check whether the clearance between the piston and the cylinder barrel is too large, whether the piston connecting rod of the electric butterfly valve is bent, and whether the surface of the piston connecting rod and the cylinder barrel are scratched or pulled.
Sometimes when driving separately, the car will vibrate as soon as it meets a small barrier. One obvious feeling is whether the car is going to fall apart.
Noise problem The electric butterfly valve makes a noise when it is in use, because the electric butterfly valve collides with the steel plate spring, frame or shaft, the rubber gasket is damaged or dropped, the dust cylinder of the electric butterfly valve is deformed, and the oil is lacking.
