SPARKLING Swing Reducer Replacement – Durable Excavator Parts

The Caterpillar Swing Reducer (Part No. 333‑3073 / 3333073) is a premium swing gearbox designed to restore smooth and powerful 360° rotation in CAT excavators—compatible with 312D, 312DL, 312D2, 312E, 313D, 313D2, 314C, and 314E models. 

It features hardened steel planetary gears, sealed bearings, and robust housing to handle heavy-duty rotational loads while preventing leaks and contamination . Available as genuine OEM or high-quality aftermarket units, this swing reducer ensures a direct-fit replacement and optimized machine performance.

   SPARKLING MACHINERY NEW 334/C2147 Radiator is a critical cooling system component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s heat dissipation system, it efficiently transfers heat from engine coolant to the surrounding air—preventing engine overheating during high-intensity operations like prolonged digging, heavy-load lifting, and continuous idling in construction, mining, or infrastructure projects. This function is vital for maintaining the engine’s optimal operating temperature (typically 82–95°C), which directly influences fuel efficiency, power output, and the long-term service life of key engine components.

   Engineered to match original equipment performance standards, it retains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and constant machinery vibration. It resists coolant leakage and internal blockages, avoiding cooling system failures that could lead to costly engine damage or unplanned downtime. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW HB205 HB215 PC200 PC200LL PC210 PC220 708-2L-07710 Valve Assy is a dedicated hydraulic control assembly for Komatsu HB205, HB215, PC200, PC200LL, PC210, and PC220 crawler excavators (widely used in construction, mining, and infrastructure projects). As the "hydraulic control hub", it integrates multiple valves to regulate oil flow, pressure, and direction—powering key functions like boom lifting, bucket digging, and swing movements, ensuring smooth, precise operation during high-intensity tasks while maintaining system stability.
   Meeting Komatsu OEM standards (part no. 708-2L-07710), it endures 30 MPa working pressure, -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and ensures leak-free performance. Strict testing guarantees seamless compatibility with the six Komatsu models and long-term hydraulic system reliability.

   The 119005-77051 Intake Air Heater is a core cold-start component for Yanmar 4TNV94 engines in Komatsu skid steers CK20-1, CK25-1, and loader SK1020-5. It preheats intake air to ensure reliable cold starts, smooth idle, and reduced emissions in low-temperature conditions, critical for consistent operation of construction machinery.

Function: This component is powered by the vehicle's battery and designed to heat the incoming air charge, which facilitates faster starts, reduces white smoke (cold emissions), and minimizes engine wear during ignition in chilly conditions.

Compatible Engines and Equipment:
· Yanmar Engines: 4TNV94L, 4TNV98, 4TNE88, and 4TNV98T series diesel engines.
· Komatsu Engines: 4D94E and 4D94LE engines.
· Komatsu Equipment: CK20-1, CK25-1, SK1020-5, SK1026-5, and PC80MR-3.
