SPARKLING Excavator Hydraulic Swivel Joint – Durable & Reliable Part

The Volvo Center Swivel Joint (part no. VOE 14652066 / 14652066) is a critical hydraulic rotary joint engineered for Volvo excavators including the EC210B, EC240B, EC290C, and EC360B. Located between the upper structure and undercarriage, this swivel joint enables smooth 360° rotation while maintaining uninterrupted hydraulic flow. Manufactured to OEM specifications in China, it ensures long-term durability and precision fit with high-strength internal bushings and reliable seals—ideal for heavy-duty rotation cycles.

   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 72281457 / 72281450 Radiator by SPARKLING MACHINERY is a high-quality aftermarket cooling solution, precisely engineered for mini excavators including Kobelco SK20SR-3, SK27SR-3 and CASE CX20B, CX22B, CX27B.

Manufactured in China with premium-grade aluminum and strict quality control standards, this radiator delivers outstanding heat dissipation, corrosion resistance, and long-term reliability — helping your machine stay cool even in the most demanding working conditions.

   SPARKLING MACHINERY NEW XB00001051 Core is a core functional component for Hitachi ZH200-A/ZH200LC-A/ZW250-5B/ZX200-5G/ZX200LC-5G/ZX210H-5G excavators (construction/mining use). It supports critical system operations (hydraulic/thermal management) with stable performance, meeting Hitachi OEM standards (XB00001051). Resistant to -30°C to 120°C temps, corrosion, and heavy-duty operational stress, it ensures seamless compatibility and reliable long-term functionality for demanding workflows.

This part is a primary replacement for medium to large Hitachi crawler excavators, specifically those in the -5 and -5G generations: 
Hitachi ZAXIS-5 Series: ZX200-5G, ZX210H-5G, ZX240-5G, ZX250H-5G, ZX330-5G, ZX350H-5G, ZX360-5, and ZX470-5G.
Other Models: ZX280-5G, ZX290LC-5B, ZX490, ZX520, ZX670, and ZX870

Part Name: Heater Core / Heating Radiator / Water Tank Radiator.
Function: Transfers heat from the engine coolant to the cabin air to provide heating for the operator. It is also listed as assisting in heating the hydraulic system in certain Hitachi models to ensure optimal operation in cold environments.
Construction: Typically features an all-aluminum tube and fin design with metal or plastic end tanks for durability against the high vibrations of heavy machinery.
