SPARKLING Hydraulic Gear Reducer

SPARKLING MACHINERY offers the KTC0185/KTC10240 gear reduction unit for CX460 and CX470B excavators, ensuring smooth torque transfer and durability under heavy-duty use. Built with high-strength materials and tested for OEM fit, it delivers reliable performance with fast global shipping and expert support.

   SPARKLING MACHINERY NEW 416F 420F 428F 430F 432F 434F 444F 360-3988 Crankshaft Main Bearing is a critical engine load-bearing and lubrication component for Caterpillar 416F, 420F, 428F, 430F, 432F, 434F, and 444F excavators (widely used in construction, mining, and municipal infrastructure projects). As the "crankshaft stability anchor", it supports the crankshaft’s rotational motion, reduces friction between the crankshaft and engine block, and absorbs radial loads from power transmission—ensuring smooth engine operation during high-intensity tasks like digging, heavy lifting, and rock breaking, while protecting core engine parts from wear.
   Meeting Caterpillar OEM standards (part no. 360-3988), it endures -30°C to 150°C engine temperatures, resists oil oxidation and metal fatigue, and maintains consistent lubrication performance. Strict testing guarantees seamless compatibility with the seven Caterpillar models and long-term engine reliability.

   SPARKLING MACHINERY NEW 14704262 Center Swivel Joint is a premium China-made hydraulic connection component designed for compatible excavators. As a critical link between the excavator’s fixed lower structure (undercarriage) and rotating upper structure (cabin, boom, and working arms), it enables uninterrupted 360° rotation while maintaining seamless hydraulic fluid transmission to core systems—including swing motors, hydraulic cylinders, and control valves. This ensures consistent power delivery for essential operations like digging, lifting, and precision swing movements in construction, mining, and earthmoving tasks.

   Engineered to original equipment standards, it maintains leak-free performance even under high hydraulic pressure (up to industry-standard thresholds) and continuous rotational stress, as well as harsh working conditions such as dust, vibration, and exposure to construction debris or moisture. With optimized high-wear-resistance sealing rings and precision-machined internal flow channels, it minimizes pressure loss and prevents fluid contamination, protecting the hydraulic system from damage. Backed by strict quality verification, it guarantees reliable operation to support uninterrupted machinery rotation and maximize work efficiency.

The 400/A7149 Hydraulic Main Pump Assembly is a high-efficiency, China-manufactured replacement pump designed to match or exceed original JCB standards. Engineered with precision and built using upgraded internal components, this pump ensures strong flow delivery, stable pressure, and reliable performance in heavy-duty construction and excavation applications.

It is a direct-fit solution for JCB models using this pump reference, providing excellent value without compromising on quality. Each unit is 100% factory-tested to guarantee durability and smooth operation under tough working conditions.
