   SPARKLING MACHINERY NEW SK485-9 DX420 DX480 472-0209 Crankshaft is a dedicated power transmission core component for Weichai-powered excavators, including SK485-9, DX420, and DX480 models (widely used in heavy construction, mining, and large-scale earthmoving). As the "engine power converter", it converts the reciprocating motion of engine pistons into rotational motion—driving key excavator systems like hydraulic pumps and generators to ensure stable power output during high-intensity tasks such as rock breaking, deep digging, and heavy lifting.
   Meeting Weichai OEM standards (part no. 472-0209), it maintains precise rotational balance, endures -30°C to 150°C engine temperatures, resists wear and vibration, and ensures long-term structural stability. Strict testing guarantees seamless compatibility with the three Weichai-powered excavator models and reliable engine operation.

   SPARKLING MACHINERY NEW 312E 416F 420F 428F 430F 432F 333-5465 Connecting Rod is a core engine power transmission component for Caterpillar 312E, 416F, 420F, 428F, 430F, and 432F excavators (widely used in construction, municipal engineering, and medium-scale mining). As the "engine motion linker", it connects the piston to the crankshaft—converting the piston’s reciprocating motion into rotational power for hydraulic pumps and accessories, ensuring stable engine output during tasks like digging, lifting, and material handling.
   Meeting Caterpillar OEM standards (part no. 333-5465), it maintains precise dimensional accuracy, endures -30°C to 150°C engine temperatures, resists high-pressure impact and wear, and guarantees structural integrity. Strict testing ensures seamless compatibility with the six Caterpillar models and long-term engine reliability.

The Cooling System Hose VOE 14643302 is a premium radiator hose designed for Volvo heavy equipment, including EC380D, EC480D, and PL4809D excavators. Manufactured in China to meet or exceed OEM specifications, this durable hose delivers reliable coolant flow and high resistance to heat, pressure, and abrasion—ensuring your engine remains cool even under heavy-duty operation. It fits seamlessly as a drop-in replacement and is available in OEM-quality or aftermarket production.
