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.

The Hydraulic Oil Cooler Assembly (part no. 11M8‑40032 / 11M8‑43120) is a high-efficiency, all‑aluminum plate‑fin heat exchanger engineered for Hyundai compact excavators—specifically R55‑7 and R55W‑7 (also fitting R60‑7). Built free of epoxy, this OEM‑spec cooler ensures optimal heat dissipation and withstands continuous high pressure (up to 2 MPa), making it a reliable drop‑in replacement for demanding operation environments

   SPARKLING MACHINERY NEW R200W7 51N6-30420 (LINK(B) ASSY-RH) & 51N6-30410 (LINK(B) ASSY-LH) is a pair of dedicated structural linkage assemblies exclusively designed for R200W7 wheel excavators. As core components of the excavator’s working mechanism, the right-hand (RH) and left-hand (LH) link assemblies work in tandem to connect critical moving parts (boom, arm, and bucket)，enabling smooth, coordinated hydraulic-driven movements. This function is essential for supporting heavy-duty tasks like road construction, material loading, and site leveling—directly ensuring the excavator’s operational precision, load-bearing stability, and resistance to mechanical jams during prolonged high-intensity work.

   Engineered to match original equipment performance standards, both assemblies maintain strong structural integrity and wear resistance even under harsh conditions (continuous load stress, vibration, dust/debris exposure). They resist deformation and connection loosening, avoiding mechanical failures that could lead to unplanned downtime or costly component damage. Backed by strict performance verification, the pair guarantees long-term reliability to support uninterrupted operation of R200W7 wheel excavators.

   SPARKLING MACHINERY New Fan Motor (VOE14531612) is a high-power drive component dedicated to VOLVO EC210B/C, EC240B/C and EC290B/C crawler excavators, which are widely applied in construction, mining and infrastructure projects. As the core power source of the excavator’s cooling fan, it accelerates heat dissipation for the engine, hydraulic oil and coolant systems, ensuring stable operating temperatures during high-intensity tasks, preventing overheating failures and avoiding unplanned downtime.

Type: Hydraulic Fan Motor.
Function: Powers the cooling fan in excavators to efficiently cool the engine and hydraulic components, preventing overheating.
