   SPARKLING MACHINERY NEW 312D2 312E 313D2 360-3986 Connecting Rod Bearing is a critical engine lubrication and load-bearing component for Caterpillar 312D2, 312E, and 313D2 excavators (widely used in construction, municipal engineering, and medium-scale mining). As the "engine motion buffer", it reduces friction between the connecting rod and crankshaft, while absorbing impact loads from piston reciprocation—ensuring smooth power transmission during tasks like digging, lifting, and material handling, and protecting the engine’s core moving parts from wear.
   Meeting Caterpillar OEM standards (part no. 360-3986), it endures -30°C to 150°C engine temperatures, resists oil oxidation and metal fatigue, and maintains stable lubrication performance. Strict testing guarantees seamless compatibility with the three Caterpillar models and long-term engine operational reliability.

   SPARKLING MACHINERY NEW ZH200-A ZH200LC-A ZX200-5G 9315463=4705920=YA00031829 Switch Box is a dedicated operator control component for Hitachi ZH200-A, ZH200LC-A, and ZX200-5G crawler excavators (widely used in construction, municipal engineering, and medium-scale earthmoving). As the "control hub" of the excavator’s cab, it houses key operation switches (e.g., ignition, work mode, auxiliary function) to transmit operator commands to the main controller—ensuring quick, accurate activation of critical functions during digging, loading, and slope trimming.
   Meeting Hitachi OEM standards (cross-referenced part nos. 9315463, 4705920, YA00031829), it endures -30°C to 85°C temperatures, resists dust and vibration, and maintains stable electrical contact. Strict testing guarantees seamless compatibility with the three Hitachi models and long-term reliable cab control.

The Throttle Controller (part no. 543‑00074 / 2543‑1036) is a high-quality electronic throttle module engineered specifically for Doosan Daewoo excavators—most notably the SOLAR 130LC-V, 150LC-V, 200W-V, 220LC-V, and related models. This plug‑and‑play controller ensures precise engine acceleration, smooth operation, and reliable performance under heavy load. With OEM-level craftsmanship or dependable aftermarket alternatives, it’s tested for durability and fast shipping globally.
