SPARKLING Swing Reducer Assembly – Durable & Precise Excavator Part

The JCB Swing Gearbox Assembly (suitable for JS70, PC60‑7, and PC70‑7/PC60‑7 excavators) is a precision-engineered swing reducer designed to deliver smooth and reliable rotational performance. Built to OEM standards (e.g., part no. LNM0639 / 201-26‑00130), this gearbox features hardened steel gears and robust bearings—ensuring durable operation under heavy load. It’s designed for easy drop-in replacement and reduces maintenance downtime. Ideal for construction, demolition, and excavation applications.

   SPARKLING MACHINERY New Water Pump (ME990328/60289472) is a critical cooling system component for heavy-duty construction machinery (excavators, loaders included). As the core of the coolant circulation system, it drives coolant through radiators and engine blocks to transfer excess heat, maintaining the engine’s optimal operating temperature (82–95°C). This prevents overheating during high-intensity tasks, safeguarding engine power, fuel efficiency and long service life.

Function: This mechanical water pump is driven by the engine belt system and circulates coolant through the engine to prevent overheating.
Construction: The pump features a robust metal construction with a quality seal to ensure leak-resistant performance and durability.
Condition: Available as new aftermarket or OEM replacement parts, designed to meet original equipment specifications for a direct fit.

Compatible Engines and Equipment:
Engines: Mitsubishi 4M50 and 4M50T diesel engines.
Excavators:
Sany SY215C
KATO HD820-V-5
Sumitomo SH60-2
Mitsubishi Fuso (some models)

The 423-22-32662 planet carrier is a durable transmission component designed for Komatsu wheel loaders WA380-5, WA380-6, WA430-5, WA400-5, WA380-7, and WA380-8. It supports planetary gears and ensures stable torque transmission, reliable drivetrain performance, and long service life under heavy-duty working conditions.

   SPARKLING MACHINERY NEW 6675-31-1011 Crankshaft is a critical power transmission component tailor-made for compatible heavy-duty diesel engines used in excavators, loaders, and industrial machinery. As the "rotational core" of the engine, it converts the reciprocating motion of pistons into continuous rotational torque, which drives the machinery’s hydraulic systems, undercarriage, and working mechanisms. This function is essential for delivering consistent power to support heavy-duty tasks like deep digging, large-volume material lifting, and continuous mining operations.

   Designed to meet original equipment performance standards, it maintains stable operation even under extreme conditions—including high rotational speeds, intense mechanical loads, and temperature fluctuations. It ensures smooth torque transfer with minimal vibration, preventing premature wear of engine components and safeguarding long-term operational efficiency. Backed by strict performance verification, it guarantees reliable power output to minimize engine downtime and keep heavy machinery running continuously.
