How many kilograms is the cylinder screw of the X-Trail?
2 Answers
The cylinder screw of the X-Trail is 8-9 kilograms. Here is an introduction about the cylinder: 1. Single-acting cylinder: Only one end has a piston rod. Air is supplied from one side of the piston to generate air pressure, which pushes the piston to produce thrust for extension, and returns via spring or self-weight. 2. Double-acting cylinder: Air is alternately supplied from both sides of the piston, generating force in one or two directions. 3. Diaphragm cylinder: Uses a diaphragm instead of a piston, generating force in only one direction and resetting via spring. It has good sealing performance but a short stroke. 4. Impact cylinder: This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of high-speed (10-20 meters/second) piston movement to perform work. The impact cylinder adds a middle cover with a nozzle and a drain port.
When I drove a Nissan Qashqai, I specifically researched the tightening torque for the valve cover screws, which is approximately 11 kgf·m, equivalent to 110 N·m. You shouldn't tighten them too loosely or too tightly, as it could lead to oil leaks or damage the gasket, making future repairs more complicated. I also noticed slight variations depending on the engine model—for example, the 1.6L gasoline engine follows this standard. Before replacing the screws, let the engine cool down, then use a torque wrench to tighten them in a star pattern step by step to ensure even force distribution and safety. During routine maintenance, check the condition of the screws to avoid breakdowns and potential hazards on the road—I always pay attention to these small details on long trips. Remember, never use a regular wrench haphazardly; professional tools are the way to go.
