SPARKLING Cat Hydraulic Shut-Off Valve – Precision & Durability

The Valve GP‑Manual (Cat part no. 389‑2407 / CA3892407) is a rugged manual auxiliary shut‑off valve designed for use in heavy-duty Caterpillar excavators—specifically models 352, 323F, 320C, 320D SA, M325D MH/L, 355, and more. It provides dependable two-way hydraulic shut-off control, helping protect critical systems during maintenance or attachments handling. Built to OEM tolerance, this valve ensures reliable operation in the harshest environments, available both as a genuine Cat part and high-quality aftermarket alternative.

The Caterpillar Swing Reducer (Part No. 333‑3073 / 3333073) is a premium swing gearbox designed to restore smooth and powerful 360° rotation in CAT excavators—compatible with 312D, 312DL, 312D2, 312E, 313D, 313D2, 314C, and 314E models. 

It features hardened steel planetary gears, sealed bearings, and robust housing to handle heavy-duty rotational loads while preventing leaks and contamination . Available as genuine OEM or high-quality aftermarket units, this swing reducer ensures a direct-fit replacement and optimized machine performance.

   SPARKLING MACHINERY NEW 4130015120001 Fan is a critical cooling system component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As a core part of the machinery’s heat dissipation system, it works with the radiator to accelerate air flow over the cooling core—effectively removing excess heat from engine coolant, hydraulic oil, or transmission fluid during high-intensity operations like digging, heavy-load lifting, and continuous idling. This function is vital for maintaining the machinery’s key systems within safe temperature ranges, preventing overheating-induced power loss, component damage, or unexpected shutdowns that disrupt construction, mining, or infrastructure projects.

   Engineered to match original equipment performance standards, it maintains stable air flow rate and structural integrity even under harsh working conditions, including high ambient temperatures (up to 45°C), continuous machinery vibration, and exposure to dust, debris, or rain. It resists blade deformation and motor failure (for electric variants), avoiding cooling inefficiencies that lead to costly downtime. Backed by strict performance verification, it guarantees reliable heat management to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW EW145B 14528776 Sealing is a premium China-made protective component specifically engineered for EW145B wheeled excavators. As a critical barrier in the machinery’s hydraulic, fuel, and coolant systems, it prevents fluid leakage (such as hydraulic oil, fuel, or engine coolant) and blocks the ingress of dust, debris, and moisture into key components—including hydraulic cylinders, pumps, control valves, and engine housings. This safeguards system integrity, reduces costly fluid waste, and avoids damage from contamination or pressure loss, ensuring reliable operation during tasks like urban construction, road maintenance, and light earthmoving.

   Designed to original equipment standards, it maintains robust sealing performance even under EW145B’s typical working conditions: high hydraulic pressure, temperature fluctuations (-40°C to 120°C), and vibration from on-road travel and off-road operation. With optimized material elasticity and precision-molded structural design, it fits tightly to component interfaces without deformation over time. Backed by strict quality verification, it guarantees long-lasting sealing effectiveness to support uninterrupted work cycles and minimize maintenance costs linked to leaks.
