SPARKLING ZGAQ-02351 Joint Housing – Reliable Excavator Part

The ZGAQ-02351 JOINT HOUSING-LH is a key left-hand structural component used in the front axle or steering assembly of Hyundai wheel excavators R200W-7, R200W-7A, and R210W-9. This joint housing provides crucial support and alignment for the axle shaft and wheel movement, ensuring smooth articulation, durability, and safe machine operation.

Crafted with high-strength cast steel and manufactured to OEM-level precision, this component is designed to endure the stress and load from rugged construction conditions. It’s an ideal replacement part for restoring steering performance and structural integrity.

   SPARKLING MACHINERY NEW 4472.319.215 Sun Gear is a dedicated power transmission component for KOMATSU excavators (heavy-duty equipment for mining, construction, and infrastructure projects). As a core part of the excavator’s planetary gear system, it meshes with planet gears to transfer rotational power, enabling smooth speed reduction and torque amplification for critical functions like track movement, boom lifting, and bucket digging during high-intensity tasks.
   Meeting KOMATSU OEM standards (part no. 4472.319.215), it endures high torque loads, -25°C to 100°C temperature fluctuations, and continuous wear. It maintains precise gear meshing and resists corrosion, ensuring long-term reliable power transmission, with strict testing guaranteeing seamless compatibility and stable performance for applicable KOMATSU models.

Hydraulic Swing Motor Assembly 4625367 for Hitachi ZX240-3, ZX240-5G, ZX250H-3, ZX250H-3G, ZX250H-5G Excavators

The 4625367 Hydraulic Swing Motor Assembly is a high-performance OEM-compatible replacement designed for Hitachi ZX240 and ZX250H series excavators. As a crucial part of the upper-structure slewing system, it transforms hydraulic energy into mechanical rotation, enabling smooth and controlled 360-degree movement of the cab and boom.

Manufactured by SPARKLING MACHINERY, this swing motor offers excellent torque, smooth operation, and long service life, making it ideal for demanding earthwork and construction applications. It is fully tested for performance, ensuring a direct-fit solution with zero leakage and superior durability.

   SPARKLING MACHINERY NEW PC490 708-1T-13450/708-1T-13620 Plate, Valve is a dedicated, high-precision hydraulic sealing component exclusively engineered for KOMATSU PC490 crawler excavators—heavy-duty equipment widely used in large-scale mining, construction, and quarrying projects. As a core sealing and pressure-regulating part of the excavator’s hydraulic valve assembly, it ensures tight sealing between valve components and assists in maintaining stable hydraulic pressure, preventing oil leakage and pressure loss during high-intensity tasks like rock breaking, bulk ore loading, and deep excavation. This function is vital for preserving hydraulic system efficiency, avoiding component damage from contamination, and reducing unplanned downtime that disrupts critical project workflows.

   Engineered to meet KOMATSU’s original equipment (OEM) standards and compatible with part numbers 708-1T-13450 and 708-1T-13620, the Valve Plate withstands harsh working conditions: high hydraulic pressure (up to 36 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil corrosion and mechanical wear, providing long-lasting sealing and pressure support for KOMATSU PC490 excavators. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for daily high-load tasks.
