   SPARKLING MACHINERY NEW 190716009 Gear Pump is a core hydraulic auxiliary component for excavators (heavy-duty construction/mining use). It delivers steady low-to-medium pressure hydraulic fluid to power auxiliary systems like steering, lubrication, or small actuators. 
   Meeting high OEM standards (190716009), it resists -30°C to 100°C temps, wear, and pressure, ensuring seamless compatibility with multiple excavator models and long-term reliable fluid supply performance.

   The 31NB-12140 Hydraulic Manifold Block is a precision-engineered flow control core for Hyundai R450LC7, R450LC7A, R480C9MH, R480LC9 crawler excavators. It integrates multiple control valves to distribute, regulate, and redirect high-pressure hydraulic oil (max 35MPa) between pumps, cylinders, and motors, ensuring smooth boom, arm, and swing movements. 

Key Features
· OEM-Matched Precision: CNC-machined carbon steel (42CrMo) body with 6 bolt-on ports (3/4" NPT), exact mounting dimensions (320×240×180mm) for Hyundai crawler excavators—no modification needed.
· High Pressure Resistance: Quenched-tempered surface (HRC 38–42) withstands 35MPa working pressure and 52.5MPa burst pressure, preventing deformation in extreme conditions.
· Leak-Proof Design: Precision lapped valve seats and nitrile rubber O-rings (temperature range -20°C to 100°C) eliminate internal/external leakage.
· Plug-and-Play Installation: Direct bolt-on fit with pre-drilled mounting holes; reduces replacement time to 2 hours

Compatible Models: This block is used in several 7-Series and 9-Series Hyundai crawler excavators, including:
· R450LC7, R450LC7A, R500LC7, R500LC7A, RD510LC-7 (7-series)
· R480C9MH, R480LC9, R480LC9A, R480LC9S, R520LC9, R520LC9A, R520LC9S (9-series)
· Interchangeable Part Numbers: 31NB-12140, 31NB12140, 31NB-12140X.
