Bosch Rexroth Valve 04950403850400A

The Rexroth Relief Valve 04950403 (part no. R901102333) is a precision-engineered screw-in cartridge valve designed for hydraulic systems in excavators and industrial machinery. This robust, direct-acting spool-type valve offers pressure reducing and relieving capabilities, withstanding up to 350 bar of maximum operating pressure and supporting flow rates around 30 L/min. Constructed with quality materials and standard CAAN cavity compatibility, it ensures responsive, leak-free hydraulic control under demanding conditions.

   SPARKLING MACHINERY NEW R215-7 R225-7 R290-7 14510586 Air Cleaner is a dedicated air filtration component for Hyundai R215-7, R225-7, and R290-7 crawler excavators (widely used in construction, mining, and infrastructure projects). As a core protector of the excavator’s engine, it filters dust, sand, and contaminants from incoming air before it enters the engine—preventing wear to pistons, cylinders, and valves while ensuring efficient fuel combustion during high-intensity tasks like heavy digging, rock breaking, and bulk material loading.
   Meeting Hyundai OEM standards (part no. 14510586), it achieves 99.5% filtration efficiency for particles ≥3μm, endures -30°C to 85°C temperatures, resists moisture and vibration, and maintains stable airflow. Strict testing guarantees seamless compatibility with the three Hyundai models and long-term engine protection.

   The 114400-3900 Turbocharger (RHG6) is a high-performance forced-induction core component, engineered for Isuzu 6HK1/6HK1T engines in Hitachi ZX330, ZX330-3, ZX350, ZX350H excavators. It boosts airflow, optimizes combustion, enhances torque/power, and ensures reliable operation under heavy loads in construction/mining sites.

Key Features
· Turbo Model: IHI RHG6
· Engine Compatibility: Isuzu 6HK1T (7.8L)
· Function: Increases engine power and torque by forcing more air into the combustion chamber.
· OEM-Perfect Fit: Matches original specs for direct, modification-free installation, saving time/labor.
· Enhanced Power: RHG6 design delivers consistent boost pressure, eliminating lag and maximizing engine output.

Compatible Equipment Models:
· Hitachi Excavators: ZX330, ZX330-3, ZX350, ZX350H, ZX350K, ZX350W, ZX360LC-HHE, ZX370MTH, ZX500W, EX300-7, EX330-5, EX330-7.
· Other Equipment: Also compatible with certain Fiat earth-moving machines using the 6HK1T engine.

   SPARKLING MACHINERY NEW SD300 130113-00035 Plate, Friction is a dedicated transmission system component for DOOSAN SD300 crawler excavators (heavy-duty equipment for mining, large-scale construction, and bulk material handling). As a key part of the excavator’s clutch or brake mechanism, it generates stable friction force to control power transmission and braking during tasks like heavy ore loading, rock breaking, and slope excavation—ensuring smooth speed adjustment and safe stopping.
   Meeting DOOSAN OEM standards (part no. 130113-00035), it endures high friction temperatures (up to 280°C), resists wear and oil contamination, and maintains consistent friction coefficient. Strict performance testing guarantees seamless compatibility and long-term reliable operation for DOOSAN SD300.
