SPARKLING 4472.218.025 Excavator Part

The ZF Joint Housing (Part Numbers: 4472.218.025, 4472.218.011, 4472.218.027, 4472.218.012) is a high-precision, heavy-duty component engineered to integrate seamlessly with ZF transmission systems in wheel loaders, construction vehicles, and other heavy machinery.

This joint housing is designed to ensure optimal alignment, torque transfer, and structural integrity between connected drive components. Manufactured from high-grade materials and built to OEM specifications, it provides excellent resistance to wear, vibration, and high-load stress.

   SPARKLING MACHINERY NEW PC490 708-1T-13440/708-1T-13610 Cylinder Block is a dedicated, high-strength structural core exclusively engineered for KOMATSU PC490 crawler excavators—heavy-duty equipment critical for large-scale mining, construction, and quarrying projects. As the foundational component of the excavator’s engine, it houses key moving parts (pistons, crankshafts) and forms the sealed chamber for fuel combustion, directly supporting engine power output and operational stability during high-intensity tasks like rock breaking, bulk ore loading, and deep excavation. This function is vital for preventing engine structural failure, maintaining consistent power delivery, and avoiding costly unplanned downtime that disrupts critical project workflows.

   Engineered to meet KOMATSU’s original equipment (OEM) standards and compatible with part numbers 708-1T-13440 and 708-1T-13610, the Cylinder Block withstands harsh working conditions: high combustion pressure (up to 18 MPa), extreme temperature fluctuations (-30°C to 120°C), and continuous vibration from heavy-duty use. It resists thermal deformation and mechanical wear, providing long-lasting structural reliability for KOMATSU PC490 excavators. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load engine tasks.

   SPARKLING MACHINERY NEW 350GLC 803M 853M RE555033 EGR Valve is a dedicated emission control component exclusively designed for 350GLC excavators and 803M, 853M loaders. As a core part of the machinery’s Exhaust Gas Recirculation (EGR) system, it precisely adjusts the flow of exhaust gas back into the engine’s intake manifold—lowering combustion temperatures to reduce nitrogen oxides (NOx) emissions. This function is critical for meeting global emission standards (such as Tier 4 Final and Euro V) while preserving the engine’s power output and fuel efficiency during heavy-duty tasks like construction digging, material loading, and site grading.

   - Engineered to match original equipment performance standards, it maintains stable valve operation even under harsh working conditions, including high exhaust temperatures, continuous machinery vibration, and exposure to exhaust contaminants. It prevents valve sticking or gas leakage, avoiding emission non-compliance and engine performance issues like power loss or increased fuel consumption. Backed by strict performance verification, it guarantees long-term reliability to support both environmental compliance and uninterrupted operation of 350GLC/803M/853M machinery.

   SPARKLING MACHINERY NEW 11221161 Cylinder Head is a core engine component for Volvo excavators (heavy-duty construction/mining use). It seals the engine cylinder top, houses valves, and ensures efficient combustion by maintaining compression. 
   Meeting Volvo OEM standards (11221161), it resists up to 300°C high temps, pressure, and corrosion, ensuring seamless compatibility and long-term reliable engine performance.
