SPARKLING Caterpillar 963D Loader Switch – Durable & Precise

The Caterpillar Switch GP-Toggle (Part No. CA1586634 / 158-6634 / 1586634) is a genuine OEM electrical component used in various CAT track loaders and excavators, including models 963D, 973D, 953D, 330D MH, and 325D.

Manufactured from high-quality polyamide plastic, this toggle switch is engineered to provide durable performance, electrical reliability, and resistance to heat, wear, and vibration — all critical for heavy-duty applications. It plays a key role in controlling specific machine functions from the operator cab, offering responsive switching and long operational life.

This part is an ideal replacement for worn or faulty switches in your Caterpillar equipment. Its precise fit and OEM-grade construction ensure hassle-free installation and consistent performance in demanding jobsite conditions.

   SPARKLING MACHINERY's new 3792809 Turbocharger is a core power-enhancing component specifically designed for Caterpillar 301.4C excavators, suitable for construction and mining applications. It enhances engine power and fuel efficiency by compressing intake air, ensuring the engine operates at optimal performance under high-load conditions.    Compliant with Caterpillar OEM standards (Part No.: 3792809), this component exhibits excellent high-temperature resistance and rotational stability, ensuring seamless compatibility with original equipment and long-term reliable operational performance.

   SPARKLING MACHINERY NEW EC460B EC460C EC480D 14541030 Swing Reducer is a premium China-made transmission component specifically engineered for EC460B, EC460C, and EC480D excavators. As a critical part of the swing system, it converts high-speed, low-torque input from the hydraulic motor into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision 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, noise, and wear, 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 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.
