The core of crankshaft repair is to choose the right method based on the degree of wear. Minor wear can be repaired by electroplating or small-sized grinding, while moderate to severe wear should be repaired by grinding or welding after grinding. Regardless of the solution, strict inspection of the dimensional tolerances and fit clearances of the shaft neck is required after repair, and the repaired crankshaft must be adequately lubricated before installation to avoid the recurrence of wear and tear faults.
The core of crankshaft installation lies in "precision" and "standardization", and any negligence in detail may lead to subsequent engine failures. Strictly following the above precautions is necessary to ensure the assembly accuracy of the crankshaft and lay the foundation for the stable operation of the engine.
The crankshaft is the core transmission component of the engine, which is subjected to periodic impact loads and rotational centrifugal forces for a long time, and is prone to various types of damage. If not repaired in a timely manner, it can cause engine shaking, power decline, and even complete machine scrapping. Mastering the common types of crankshaft damage and maintenance methods is the key to ensuring stable engine operation.

4.1 Automotive Segment: EcoBoost 2.0L Turbo EngineTopping the automotive category, the EcoBoost 2.0L turbo engine delivers 250 HP, 370 N·m torque, and 35 MPG fuel efficiency. Our tests showed it outperforms competitors in 0-60 mph acceleration (6.2 seconds) and maintains efficiency even under heavy
5.1 Skipping Oil ChangesOld oil loses its lubricating properties, causing metal-on-metal friction that damages cylinders and bearings. Follow the manufacturer’s recommended oil change schedule—never delay due to "low usage."5.2 Using the Wrong Fuel GradeLow-quality or incorrect fuel grades clog inje
7.1 Calculate Power RequirementsDetermine your maximum load (including peak demand) and select an engine with a 10-15% power reserve. This ensures the engine doesn’t strain under heavy use and provides consistent performance.7.2 Prioritize Durability FeaturesIndustrial engines need reinforced cranks
Small Engine Buying: The Art of Balancing Power & Fuel Efficiency6.1 Match Power to TaskFor light tasks (lawnmowers, trimmers), a 3-5 HP 4-stroke engine is sufficient—no need for excess power that wastes fuel. For heavier tasks (small tillers, pressure washers), opt for 7-10 HP engines with variable
