RE279132 John Deere Hydraulic Pump 6D Series 200Bar

Product Overview:

Engineered for the demanding and rigorous environments of agricultural operations, our high-performance replacement hydraulic pump is explicitly designed for the John Deere 6D series tractors. Covering multiple core OEM part numbers including RE279132, RE263420, and RE546917, this pump delivers consistent hydraulic power and precise steering control. As a specialized manufacturer of high-pressure hydraulic components, we guarantee 100% interchangeability—allowing for a seamless, modification-free installation. Every single unit undergoes 100% simulated working condition testing before dispatch, ensuring exceptional volumetric efficiency and durability even under peak loads and extreme temperatures. It is the ultimate aftermarket upgrade for your agricultural machinery.

Key Technical Advantages:

• 100% Interchangeability (Drop-in Ready): Precisely reverse-engineered to match the exact flange, splined shaft, and port dimensions of the original John Deere equipment, ensuring a swift, plug-and-play installation for field mechanics.

• Superior Volumetric Efficiency: Constructed with a high-strength cast-iron housing and precision-ground gears. Integrated with floating bushing clearance compensation technology, it maintains a volumetric efficiency of over 95% while minimizing internal leakage under continuous 200-bar pressure.

• 100% Simulated Working Condition Testing: Zero compromise on quality. Every assembled pump is subjected to rigorous thermal cycling, pressure shock, and full-load flow testing on our automated test rigs, meeting or exceeding OEM performance benchmarks.

• Extended Lifespan & Anti-Cavitation Design: Built with heavy-duty needle bearings and high-temperature FKM (Viton) lip seals to withstand thermal degradation. The optimized suction port geometry significantly mitigates the risk of cavitation at high operating speeds.

Application Areas:

Specifically designed for the open-center hydraulic circuits of John Deere 6D series utility tractors (6100D to 6140D). This tandem unit supplies primary hydraulic fluid power to the rear hitch and Selective Control Valves (SCVs) while simultaneously providing an independent, steady flow to the hydrostatic steering system.

Expert Maintenance Tips:

• System Flushing: Always drain and flush the entire hydraulic circuit prior to installation. Metal debris left from a previous pump failure will instantly contaminate and permanently damage the new unit.

• Suction Line Inspection: Rigorously check all suction lines and flange connections for air leaks. Aeration is the leading cause of gear pump cavitation, abnormal noise, and premature failure.

• Fluid Recommendations: We highly recommend using John Deere Hy-Gard transmission and hydraulic oil (JDM J20C specification) or a high-quality ISO VG 46/68 anti-wear hydraulic fluid. Inspect the hydraulic filters after the first 50 hours of operation.
