RE241577 John Deere Hydraulic Pump 5M Series 200Bar

Product Overview:

Engineered to withstand the high-intensity operations of modern agricultural machinery, our premium replacement hydraulic pump is specifically developed for John Deere 5M series tractors, notably the 5065M and 5075M models. Flawlessly replacing core OEM part numbers such as RE241577, RE241578, RE264113, and RE284521, this tandem unit delivers a highly reliable dual power source for both main implement and steering systems. As a dedicated manufacturer of high-pressure hydraulic components, we guarantee 100% interchangeability—allowing for a seamless, drop-in installation without any required modifications to existing hoses or flanges. Every single pump is subjected to 100% simulated working condition testing before leaving our facility, ensuring sustained volumetric efficiency and an extended operational lifespan even under extreme agricultural temperatures and heavy-duty loads.

Technical Specifications:

• Replaces OEM Part Numbers: RE241577, RE241578, RE264113, RE284521

Key Technical Advantages:

• 100% Interchangeability (Drop-in Ready): Precisely reverse-engineered against original factory parameters. The mounting flange hole distances, splined shaft module/teeth count, and port dimensions are manufactured with high precision, guaranteeing field technicians a true plug-and-play replacement.

• High-Strength Housing & Superior Volumetric Efficiency: Constructed from heavy-duty alloy cast iron/specialty extruded aluminum and equipped with precision-ground gears and floating bushings. This clearance compensation technology maintains volumetric efficiency above 95% by strictly controlling internal leakage, even under a continuous 200-bar pressure.

• 100% Simulated Working Condition Testing: We enforce the most stringent quality control standards with zero tolerance for batch sampling. Every assembled pump must pass thermal shock, pressure pulsation, and full-flow load tests on automated rigs, meeting or exceeding all OEM performance criteria.

• Heavy-Duty Bearings & Low-Noise Profile: Fitted with high-load-capacity needle roller bearings to effortlessly withstand the intense radial forces generated during rough terrain operations. The optimized gear profile and relief groove geometry significantly reduce fluid pulsation and mechanical noise at high rotational speeds.

Application Areas:

Specifically designed for the open-center hydraulic circuits of John Deere 5M series utility tractors. The primary (front) pump supplies robust hydraulic power to main implement systems, including the rear hitch, Selective Control Valves (SCVs), and front loaders. The secondary (rear) pump is dedicated to providing an independent, steady fluid flow to the hydrostatic steering system, ensuring precise and effortless maneuverability across all field conditions.

Expert Maintenance Tips:

• Deep System Flushing: The biggest enemy of a new gear pump is old contamination. Prior to installation, completely drain and flush the entire hydraulic circuit and replace all filters. Metal debris from a previous pump failure will instantly score the internals of the new unit.

• Suction Line Seal Inspection: When connecting flanges and suction lines, ensure O-rings and gaskets are immaculate and tightened correctly. Air ingress (aeration) leads to severe cavitation, causing abnormal, high-pitched whining noises and rapid internal destruction.

• Fluid Specifications: We highly recommend using John Deere Hy-Gard transmission and hydraulic fluid (JDM J20C specification) or a premium ISO VG 46/68 anti-wear hydraulic oil. Perform a routine inspection after the first 50 hours of initial operation.
