SPARKLING ZGAQ-02052 Shaft – Durable Excavator Spare Part

The ZGAQ-02052 Shaft-Input is a critical drivetrain component specifically designed for HYUNDAI Wheel Excavators, including models R140W-7, R140W-9A, R140W-9S, R170W-7, and R170W-7A. This input shaft is responsible for transmitting torque efficiently from the transmission to the differential or gearbox, ensuring smooth and reliable machine operation.

Manufactured with high-grade alloy steel and precision machining, the ZGAQ-02052 offers excellent durability, high-load resistance, and long service life — even under the harsh conditions of construction and excavation environments.

SPARKLING MACHINERY proudly presents The 21Q4-32213/32210 HCE MCU Control Unit - a premium Made in China OEM-compatible solution specifically engineered for Hyundai R140W-9S excavators. This advanced control module integrates Hydraulic Control Electronics (HCE) with a high-performance 32-bit MCU, delivering precise machine operation through CAN J1939 communication protocol. Designed for extreme conditions, it features an IP67-rated rugged enclosure and operates reliably in -30°C to +75°C environments. With real-time diagnostics and CE/ISO 13849 certification, our unit ensures your excavator maintains peak performance while reducing downtime. Offering plug-and-play replacement with 3-year warranty coverage, it's the smart choice for fleet managers seeking cost-effective, durable alternatives to OEM parts.

   SPARKLING MACHINERY NEW R290LC9 R290LC9MH R300LC9A 39Q8-12100 Swing Reduction Gear is a premium China-made transmission component specifically engineered for R290LC9, R290LC9MH, and R300LC9A excavators. As a critical part of the swing system, it transforms high-speed, low-torque input into low-speed, high-torque output, enabling smooth and precise rotation of the upper structure (boom, arm, and bucket) during positioning, material handling, and heavy-duty operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear meshing design for minimal friction and noise, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW R140W7 R140W7A R170W7 XKBF-00100 Lock Valve Kit-A is a dedicated, high-precision hydraulic safety assembly exclusively engineered for HITACHI R140W7, R140W7A, and R170W7 wheeled excavators—versatile equipment widely used in road construction, municipal engineering, and urban infrastructure projects. As a core safety component of the excavator’s hydraulic system, it locks the position of key mechanisms (boom, arm, bucket) when the excavator is stationary or during operator breaks, preventing accidental movement caused by hydraulic pressure loss. This function is vital for protecting on-site workers, avoiding equipment collisions, and ensuring operational safety during tasks like road repair, material handling, and urban demolition.

   Engineered to meet HITACHI’s original equipment (OEM) standards and marked with the genuine part number XKBF-00100, the Lock Valve Kit-A withstands harsh working conditions: high hydraulic pressure (up to 32 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from on-road travel and off-road work. It resists oil contamination and mechanical wear, providing long-lasting safety protection for the three HITACHI wheeled excavator models. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for daily excavator tasks.
