CASE EXCAVATOR PARTS MADE IN CHINA NEW CX350C CX290B CX300C CX800B CX460 KHH10850 RESERVE TANK SPARKLING MACHINERY
SPARKLING MACHINERY NEW CX350C CX290B CX300C CX800B CX460 KHH10850 Reserve Tank is a dedicated fluid storage component for CASE CX350C, CX290B, CX300C, CX800B, and CX460 crawler excavators (heavy-duty equipment for mining, construction, and infrastructure projects). As a key part of the excavator’s cooling or hydraulic system, it stores and supplements coolant or hydraulic oil, maintaining stable fluid levels to prevent overheating or pressure loss during high-intensity tasks like rock breaking and bulk material loading.
Meeting CASE OEM standards (part no. KHH10850), it endures -30°C to 110°C temperatures, resists fluid corrosion and impact, and ensures leak-free storage. Strict testing guarantees seamless compatibility and long-term reliable performance for the five CASE models.

MADE IN CHINA SPARKLING MACHINERY NEW R80-7 11N1-40011 RADIATOR ASSY
SPARKLING MACHINERY NEW R80-7 11N1-40011 Radiator Assy is a dedicated cooling system assembly exclusively designed for R80-7 excavators. As the integrated core of the excavator’s heat dissipation system, it combines radiator functionality with compatible mounting and connection components to efficiently transfer heat from engine coolant to the surrounding air. This is critical for preventing engine overheating during tasks like small-scale construction, agricultural land preparation, and urban infrastructure maintenance—directly ensuring the R80-7’s stable power output, fuel efficiency, and long-term engine service life.
Engineered to match original equipment performance standards, it maintains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous excavator vibration. It resists coolant leakage and internal blockages, avoiding cooling system failures that could lead to unplanned downtime or costly engine repairs. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of R80-7 excavators.
MADE IN CHINA SPARKLING MACHINERY NEW EC250D EC250E 14632317 HYDRAULIC PUMP
SPARKLING MACHINERY NEW EC250D EC250E 14632317 Hydraulic Pump is a premium China-made power component specifically engineered for EC250D and EC250E excavators. As the core of the hydraulic system, it converts mechanical energy into hydraulic pressure, driving critical operations such as boom lifting, arm articulation, and bucket movement through controlled fluid flow. This ensures efficient power transmission and responsive machinery performance in construction, mining, and medium to heavy-duty earthmoving applications.
Designed to original equipment standards, it maintains stable pressure output and consistent flow rates even under continuous high-load operation. With optimized internal design for minimal energy loss and enhanced wear resistance, it adapts seamlessly to harsh working environments, from dusty job sites to high-temperature conditions. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted machinery operation.
