SPARKLING Carrier Gear Disc – Durable Excavator Parts

The 4472-377-047 Carrier Disc is a critical transmission component designed for the HYUNDAI R170W-7 Wheel Excavator. As part of the planetary gear assembly, the carrier disc ensures smooth torque transfer and balanced load distribution within the drive system, supporting reliable movement and effective excavation operations.

Manufactured with high-strength materials and strict quality control, this carrier disc (also referenced as 4472377047 or 4472.377.047) offers precise fitment and extended durability, making it a cost-effective and dependable replacement for OEM parts.

   SPARKLING MACHINERY NEW 31Q8-01330 Cover Return is a core protective component for Hyundai excavators (heavy-duty construction/mining use). It shields hydraulic or mechanical return systems from dust, debris, and moisture, ensuring unobstructed fluid flow and component integrity. 
   Meeting Hyundai OEM standards (31Q8-01330), it resists -30°C to 100°C temps, corrosion, and vibration, ensuring seamless compatibility and long-term reliable protective performance.

   The HIGH-QUALITY 270-6217 GEAR IDLER is a premium power transmission component meticulously engineered for Caterpillar Construction Equipment, specifically tailored to meet the precision alignment and durability demands of 303.5C, 303.5D, 303C CR, 304C CR, and 304D CR Mini Hydraulic Excavators. As a critical part of the machinery’s drive system, this gear idler maintains optimal tension and alignment of drive gears or chains, ensuring smooth power distribution, reducing mechanical wear, and preventing component misalignment during compact-scale construction tasks. 
   Designed to seamlessly integrate with Caterpillar’s mini excavator architecture, it delivers consistent performance that enhances machinery operational efficiency, extends drive system service life, and ensures reliable performance in tight or demanding workspaces.
