SPARKLING DOOSAN DX190W Parts – Reliable Excavator Components

The K9001469 Bevel Gear is a critical drivetrain component specifically engineered for DOOSAN wheeled excavators including models DX140W, DX170W, DX190W, and SOLAR 185W-V. It is designed to efficiently transmit power between intersecting shafts at precise angles, enabling smooth and reliable torque delivery in the swing or travel reduction gear systems.

Manufactured with premium-grade alloy steel and finished with precision gear-cutting technology, this bevel gear ensures high wear resistance, quiet operation, and extended service life — even in rugged construction environments.

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 440-00257 Cylinder;Arm is a dedicated hydraulic actuation component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s arm movement system, it converts hydraulic pressure into linear force to drive the arm’s lifting, lowering, and extending actions—supporting critical on-site tasks like digging, material grabbing, and precision placement in construction, mining, or infrastructure projects. This function is essential for maintaining the machinery’s operational flexibility and load-bearing capacity, directly ensuring smooth coordination between the arm and bucket, and preventing movement lag or jams that could reduce work efficiency or cause safety hazards.

   Engineered to match original equipment performance standards, it maintains stable pressure retention and smooth piston movement even under harsh working conditions, including heavy load stress (up to rated 500 kN), continuous vibration, and exposure to dust or hydraulic oil contaminants. It resists internal leakage and cylinder wall wear, avoiding hydraulic system inefficiencies that lead to unplanned downtime. Backed by strict performance verification, it guarantees reliable arm actuation to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW EC220D EC235D EC250D EC250E EC300D 14592299 Relief Valve is a dedicated hydraulic safety component for VOLVO EC220D/EC235D/EC250D/EC250E/EC300D crawler excavators (heavy-duty equipment for construction/mining). As the hydraulic system’s core safety guard, it precisely limits max pressure to protect pumps, cylinders, and pipelines from overload damage during rock breaking or bulk loading.

   Meeting VOLVO OEM standards (part no. 14592299), it endures 34 MPa pressure, -25°C to 105°C temps, and heavy vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing compatibility and safe operation.
