SPARKLING CAT 330D Toggle Control – Precision Excavator Parts

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 NEW 0501-314-382 Clutch Disc S210W is a premium China-made transmission component specifically engineered for S210W wheel excavators. As a key part of the clutch system, it facilitates smooth power transfer between the engine and drivetrain by generating controlled friction to engage or disengage mechanical power, ensuring precise operation during gear shifts, acceleration, and load adjustments.

   Designed to original equipment standards, it maintains consistent friction performance and heat resistance, operating reliably even under high-torque conditions and prolonged use. With optimized structural design for efficient torque transmission, it adapts seamlessly to harsh working environments, from dusty construction sites to rugged terrain. Backed by strict quality verification, it guarantees stable performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 420E 422F 428F 430E 432F 348-9761 Valve GP-P R is a dedicated hydraulic pressure reducing valve group for Caterpillar 420E, 422F, 428F, 430E, and 432F backhoe loaders/excavators (widely used in construction, municipal engineering, and heavy material handling). As a core pressure control component, it reduces high-pressure oil from the main hydraulic system to a stable, safe level for sensitive sub-systems (e.g., hydraulic steering, auxiliary controls)—ensuring smooth, damage-free operation during tasks like heavy digging, loading, and backhoe maneuvering.
   Meeting Caterpillar OEM standards (part no. 348-9761), it endures 28 MPa inlet pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains consistent pressure reduction. Strict testing guarantees seamless compatibility with the five models and long-term hydraulic sub-system protection.

   SPARKLING MACHINERY NEW EC210B EC460B 14512954 Seal Kit is a dedicated, all-in-one sealing solution exclusively engineered for VOLVO EC210B and EC460B excavators—key equipment in heavy construction, mining, and large-scale infrastructure projects. As a core protective component for the excavators’ hydraulic systems, it covers critical areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming reliable leakproof barriers. This function is essential for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of core mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust or debris from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during high-intensity, prolonged operations (such as rock breaking, bulk material loading, and deep excavation).

   Engineered to match VOLVO’s original equipment standards, the seal kit maintains consistent sealing reliability even under harsh conditions: high hydraulic pressure (up to 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous excavator vibration. It resists oil aging and wear, providing long-lasting protection for the excavators’ hydraulic systems. Backed by strict performance verification, it guarantees uninterrupted sealing support for EC210B/EC460B excavators.
