Can an engine connecting rod be replaced individually?
2 Answers
Yes, as long as the replaced parts are normal components and the assembly is done properly, it will not affect the vehicle. Here is relevant information: 1. Definition: The automobile engine is the device that provides power to the vehicle, serving as the heart of the car and determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, automobile engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others. 2. Maintenance and repair: Automobile engines require regular maintenance. When driving through areas that are particularly humid or have high levels of dust, it is also necessary to inspect and maintain the relevant components of the engine.
When I worked at the auto repair shop, I learned that connecting rods should never be replaced individually. Replacing a single connecting rod in a four-cylinder engine is like wearing shoes of different sizes – it'll definitely cause imbalance! Even a few grams of weight difference between the new and old rods can be dangerous. The vibration from the high-speed rotating crankshaft can crack the piston rings in other cylinders. Last time, my boss took a job where the customer tried to save money by only replacing the connecting rod in the third cylinder. After just 2,000 kilometers, it severely scored the cylinder wall, ending up costing three times more for a complete overhaul. Professional repair shops always replace the full set and use precision scales for balancing. While the labor cost may seem expensive, it actually ensures trouble-free operation for at least three years.
