F000510642 73402541 Rexroth Hydraulic Gear Pump

Hydraulic Tandem Gear Pump for CNH / Case IH / New Holland | PN: 73402541

The 73402541 is a high-performance tandem (dual) hydraulic gear pump manufactured by RCHC, serving as a perfect replacement for equivalent gear pump models from Bosch Rexroth or Casappa. It is a vital component for CNH Global machinery, specifically designed to provide independent hydraulic flow for steering and secondary hydraulic functions in tractors and loaders.

Product Compatibility

This tandem pump is a direct replacement for various Case IH and New Holland agricultural and construction models, including:

• New Holland Tractors: 5630, 6630, 7630, 8030
• Case IH Tractors: Maxxum and Farmall series variants (depending on regional specifications)
• CNH Engines: Widely used on equipment powered by Genesis and NEF engines.

Technical Specifications

• Part Number: 73402541
• OEM Cross-Reference: 87540838, 82012020, 5179722, 5179725
• Pump Configuration: Tandem Gear (Double Pump)
• Rotation: Clockwise (CW) or Anti-clockwise (CCW)
• Shaft Design: 13-Spline Splined Shaft
• Maximum Speed:3000rpm
• Maximum Continuous Pressure:210-250bar

Key Features and Benefits

• Dedicated Steering Safety: The tandem design ensures that the steering circuit receives a constant priority flow, maintaining operator control even when the main hydraulic lift or remote valves are under maximum load.
• OEM Standard Performance: Manufactured to CNH’s rigorous specifications to ensure proper flow rates and pressure settings, preventing damage to the tractor’s hydraulic valves.
• Heavy-Duty Housing: Constructed with reinforced cast iron or high-grade aluminum to resist body deflection and internal leakage under high-temperature operations.
• Direct Fitment: Precision-machined to match the factory mounting flange, ensuring a leak-free seal and perfect gear alignment with the engine drive.
• High Volumetric Efficiency: Optimized gear tolerances reduce internal bypass, maximizing the hydraulic power delivered to the implements.
