SPARKLING Swing Motor Gearbox – Reliable Excavator Part

The JCB Swing Gearbox Assembly (suitable for JS70, PC60‑7, and PC70‑7/PC60‑7 excavators) is a precision-engineered swing reducer designed to deliver smooth and reliable rotational performance. Built to OEM standards (e.g., part no. LNM0639 / 201-26‑00130), this gearbox features hardened steel gears and robust bearings—ensuring durable operation under heavy load. It’s designed for easy drop-in replacement and reduces maintenance downtime. Ideal for construction, demolition, and excavation applications.

   SPARKLING MACHINERY NEW 119266-21700 Crankshaft is a premium China-made engine core component designed for compatible construction machinery (such as excavators, loaders, and generators) and industrial engines. As the "power transmission backbone" of the engine, it converts the reciprocating motion of pistons into rotational motion to drive the machinery’s hydraulic system, undercarriage, and other key components. This critical function ensures the engine delivers consistent torque and power for heavy-duty operations—including digging, lifting, and continuous power generation—in construction, mining, and industrial scenarios.

   Engineered to original equipment standards, it maintains exceptional structural stability even under high rotational speeds (up to industry-standard RPM thresholds) and extreme load conditions, as well as harsh working environments like vibration, temperature fluctuations, and dust. With precision-machined journals and balanced design, it minimizes friction between moving parts and reduces engine vibration. Backed by strict quality verification, it guarantees reliable power transmission to support uninterrupted machinery operation and extend overall engine service life.

SPARKLING Hyundai Excavator Pressure Sensor (31LF-00500) is designed for Hyundai Heavy Equipment models R140W-7, R140W-7A, R170W-7, R170W-7A, and R200W-7. Ensures precise hydraulic system performance and durability for Hyundai Construction Equipment.

   SPARKLING MACHINERY NEW 440211-01543 DX490LC-7M (OEM) Radiator is an exclusive OEM-standard cooling core component designed specifically for DX490LC-7M large excavators—commonly used in heavy mining, large-scale construction, and infrastructure projects. As the core of the excavator’s engine cooling system, it efficiently dissipates excess heat generated by the high-power engine during prolonged heavy-load operations (such as rock breaking, bulk material loading, and deep excavation) by transferring heat from coolant to ambient air. This function is critical for maintaining the engine’s optimal operating temperature (85–95°C), preventing overheating-induced power loss, cylinder head warping, or irreversible engine damage, while ensuring consistent productivity in demanding work environments.

   Engineered to meet 100% OEM specifications, it maintains superior heat dissipation efficiency even under harsh conditions—including high ambient temperatures (up to 50°C), continuous excavator vibration, and exposure to dust, gravel, or heavy rain. It resists coolant leakage and core corrosion, avoiding cooling system failures that lead to costly unplanned downtime. Backed by strict OEM-level performance verification, it guarantees reliable heat management to support uninterrupted operation of DX490LC-7M excavators.
