SPARKLING OEM Bearing Pin – Precision & Durability Since 2013

The ZF 4472397016 (also listed as 4472.397.016 / 4472-397-016) Bearing Pin is a high-precision component designed to provide reliable rotational alignment and structural support in ZF transmission and axle assemblies. Built from heat-treated, wear-resistant steel, this pin ensures long-term durability and smooth mechanical movement under heavy-duty conditions.

It is a perfect fit for ZF machinery applications where stability, strength, and OEM compatibility are essential. Each pin is manufactured to strict tolerances and undergoes rigorous quality control to meet or exceed OEM standards.

   SPARKLING MACHINERY NEW 2420-1125A Valve; By-Pass 4.5B is a dedicated hydraulic pressure regulation component for Doosan excavators (widely used in construction, mining, and municipal engineering). As the "hydraulic pressure buffer", it diverts excess hydraulic oil back to the tank when system pressure reaches 4.5B (bar) — preventing overpressure damage to pumps, valves, and cylinders during tasks like digging, lifting, and rock breaking, while ensuring stable oil flow for critical operations.
   Meeting Doosan OEM standards (part no. 2420-1125A), it maintains precise pressure control (4.5B set threshold), endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and ensures leak-free performance. Strict testing guarantees seamless compatibility with applicable Doosan models and long-term hydraulic system safety.

 SPARKLING MACHINERY NEW 416F 420F 422F 428F 3435643 343-5643 Air Cleaner is a dedicated air filtration component exclusively designed for 416F, 420F, 422F, and 428F construction machinery (such as backhoes and loaders). As a core part of the machinery’s engine protection system, it efficiently filters dust, debris, and other contaminants from incoming air before it enters the engine combustion chamber. This function is critical for preventing abrasive particles from damaging engine components (e.g., pistons, cylinders, and valves) during heavy-duty operations like excavation, material handling, and site grading—directly preserving engine performance, extending service life, and reducing maintenance frequency.

   Engineered to match original equipment performance standards, it maintains high filtration efficiency (over 99.5% for particles ≥3μm) even under harsh working conditions, including dusty construction sites, gravel yards, and agricultural fields. It resists clogging and air flow restriction, avoiding engine power loss or overheating caused by insufficient air supply. Backed by strict performance verification, it guarantees reliable air purification to support uninterrupted operation of 416F/420F/422F/428F machinery.

   SPARKLING MACHINERY NEW EC210B EC240B EC290B EC350 7270-11161(14636708) Relief Valve is a critical hydraulic safety component for Volvo EC210B, EC240B, EC290B, and EC350 excavators (widely used in construction, mining, and medium-scale earthmoving). As the "hydraulic pressure protector", it automatically releases excess pressure from hydraulic systems during tasks like digging, boom lifting, and rock breaking—preventing overpressure-induced damage to pumps, valves, and cylinders, while ensuring stable pressure output for smooth equipment operation.
   Meeting Volvo OEM standards (part nos. 7270-11161/14636708), it endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees precise pressure relief. Strict testing ensures seamless compatibility with the four Volvo models and long-term hydraulic system safety.
