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 EC135B EC140 EC140B EC160B 14514937 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC135B, EC140, EC140B, and EC160B excavators—key equipment in construction, mining, and municipal infrastructure projects. As a core protective component for the excavators’ hydraulic systems, it covers critical areas such as 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 operations like trench digging, material loading, and site grading.

   Engineered to match VOLVO’s original equipment standards, the seal kit maintains consistent sealing reliability even under harsh conditions: high hydraulic pressure (up to 35 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 EC135B/EC140/EC140B/EC160B excavators.

   The 283-3074 toggle switch is a 32V four-pole (four-circuit) control switch for Caterpillar excavators 311C/330D/345C (also fits 312C/312D/320C/320D/325C/330C/345D). It acts as a reliable circuit selector for functions like work mode (auto/manual), auxiliary hydraulics, or travel speed control, ensuring precise operation in heavy-duty construction.

Key Features
· OEM-Matched Precision: Exact 4-pole contact layout, M12×1 panel thread, and terminal pitch—plug-and-play for Cat cabs.
· Durable Construction: Reinforced PA66 housing (IP65 dust/waterproof); silver-plated copper contacts for low resistance (<50mΩ) and anti-oxidation.
· Stable Electrical Performance: 32V DC rated, 10A per pole; -40°C to 85°C operating temp for extreme worksites.
· Long Mechanical Life: 10,000+ toggle cycles; tactile detent for clear mode feedback, reducing misoperation.

Compatible Equipment
The 283-3074 toggle switch assembly is used across a wide range of Caterpillar machinery and engines: 
· Excavators: Models like the 311C, 312C/D, 320C/D, 323D, 325C/D, 330D, and 345C are compatible.
· Engines: It is compatible with various Cat engines, including the 3046, 3054, 3066, C7, and C9 series.
· Other Machinery: It also fits certain wheeled excavators and forest machines.

   SPARKLING MACHINERY NEW ZX30 ZX35 ZX40U 4434315 Radiator is a dedicated cooling system component exclusively designed for ZX30, ZX35, and ZX40U mini excavators. As the core of these machines’ heat dissipation systems, it efficiently transfers heat from engine coolant to the surrounding air—preventing engine overheating during tasks like urban landscaping, small-scale construction, and agricultural maintenance. This function is critical for maintaining the excavators’ optimal operating temperature (typically 82–95°C), which directly ensures stable engine power output, fuel efficiency, and 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 continuous machine vibration. It resists coolant leakage and internal blockages, avoiding cooling system failures that could lead to unplanned downtime or costly engine damage. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of ZX30/ZX35/ZX40U excavators.
