SPARKLING 325D Switch Assembly – Reliable Excavator Replacement Part

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.

The ZGAQ-02351 JOINT HOUSING-LH is a key left-hand structural component used in the front axle or steering assembly of Hyundai wheel excavators R200W-7, R200W-7A, and R210W-9. This joint housing provides crucial support and alignment for the axle shaft and wheel movement, ensuring smooth articulation, durability, and safe machine operation.

Crafted with high-strength cast steel and manufactured to OEM-level precision, this component is designed to endure the stress and load from rugged construction conditions. It’s an ideal replacement part for restoring steering performance and structural integrity.

   SPARKLING MACHINERY NEW 320D 320D2 312-8338 Oil Cooler is a dedicated thermal management component exclusively designed for 320D and 320D2 excavators. As a core part of the excavators’ hydraulic and engine systems, it efficiently dissipates heat from hydraulic oil and engine oil—preventing oil overheating during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance. This function is critical for preserving oil viscosity and lubrication performance, which directly protects key components (such as hydraulic pumps, valves, and engine bearings) from premature wear, ensuring stable power output and extending the service life of 320D/320D2 machinery.

   Engineered to match original equipment performance standards, it maintains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous excavator vibration. It resists oil leakage and internal blockages, avoiding system failures that could lead to unplanned downtime or costly component repairs. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of 320D and 320D2 excavators.

   SPARKLING MACHINERY NEW EC120D EC140B EC140C EC140D EC140E 14524582 Relief Valve is a dedicated hydraulic safety component for VOLVO EC120D, EC140B, EC140C, EC140D, and EC140E crawler excavators (mid-sized equipment for construction, municipal engineering, and light mining). As the core safety guard of the hydraulic system, it precisely limits maximum pressure to protect pumps, cylinders, and pipelines from overload damage during trench digging, material loading, and small-scale rock breaking.

   Meeting VOLVO OEM standards (part no. 14524582), it endures 30 MPa pressure, -25°C to 105°C temperature fluctuations, and continuous vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing seamless compatibility and safe operation.
