If a crankshaft is not turning by hand, it could indicate a serious issue such as a seized engine, hydrolocking, or internal mechanical damage like a broken timing belt or damaged bearings. Diagnosing the problem promptly is crucial to avoid further damage and costly repairs. Professional inspection may be necessary to determine the exact cause. … Read more
To tell if a crankshaft is forged or cast, you can check the parting line, surface texture, and weight. Forged crankshafts have a narrow, sharp parting line, smoother surface, and are generally heavier due to their denser material. In contrast, cast crankshafts have a wider, rounded parting line, a rougher texture, and are lighter. Additionally, … Read more
Yes, fully counterweighted crankshafts are durable due to their superior balance and reduced vibration, which minimizes wear and stress on engine components. Their design enhances the longevity of the crankshaft, making them ideal for high-performance and heavy-duty applications. The use of high-quality materials and precision manufacturing further contributes to their durability. A crankshaft is a … Read more
Crankshaft bearings are typically made from materials like Babbitt metal, copper-lead alloys, aluminum alloys, tri-metal layers, and polymers. Each material is chosen for its specific properties, such as strength, wear resistance, and ability to handle high temperatures. The selection of material depends on the engine’s performance requirements and operating conditions. Crankshaft bearings play a crucial … Read more
Crankshaft journal welding is a repair technique used to restore damaged or worn crankshaft journals by applying a specialized weld material to build up the surface. This process is followed by precise machining and grinding to achieve the original specifications and ensure proper engine function. It is a cost-effective alternative to replacing the crankshaft, extending … Read more
A crankshaft journal polishing tool is used to smooth and refine the surfaces of crankshaft journals, removing minor imperfections and wear marks. This tool helps reduce friction, extend bearing life, and improve engine performance by creating a smooth surface for the bearings to glide against. It can be handheld or machine-driven, depending on the application. … Read more
