Ford 2610 3610 5110 5610 6410 6610 7810 7910 8210 Tractor Hydraulic Gear Pump Replacement – 33ml

GBC-D8NN600FA — Ford 2610 3610 5110 5610 6410 6610 7810 7910 8210 Tractor Hydraulic Gear Pump Replacement – 33ml

Ford's broader mid-range and heavy-utility tractor lineup — the 2610, 3610, 5110, 5610, 6410, 6610, 7810, 7910, and 8210 — covered a wide horsepower range and formed the backbone of arable and mixed farming operations across Australia through the 1980s and 1990s. These tractors require a higher-output hydraulic pump than the smaller compact models, reflected in the 33.0 ml/r displacement and elevated 200 bar maximum pressure rating. The pump has left-hand (anti-clockwise) shaft rotation, a Φ19 mm inlet bore, and a Φ28 mm discharge bore.

The GBC-D8NN600FA is a direct-replacement hydraulic gear pump for this Ford series, matching OEM references D8NN600FA, 83913537, 83945584, and 83903943. Its 33.0 ml/r displacement and 200 bar rating make it one of the highest-output gear pumps in the Ford tractor range, delivering the flow volume necessary for responsive three-point linkage, multiple remote cylinders, and front-loader operation on larger machines.

MOQ: flexible. Minimum order value USD 1,500; mixed orders and trial quantities welcome.

OEM Reference Numbers and Fitment

The GBC-D8NN600FA replaces Ford part numbers D8NN600FA, 83913537, 83945584, and 83903943. The D8NN600FA designation is the primary reference used in Ford's service parts system. The 83xxxxxx numbers are the stamped service part numbers used in the Ford-New Holland parts supply chain from the mid-1980s onwards. If your pump carries any of these numbers — whether on the body casting, a label, or in the parts fiche for your tractor — the GBC-D8NN600FA is the correct aftermarket replacement. Contact us to confirm fitment.

Technical Specifications

Higher-Pressure, Higher-Flow Applications

The GBC-D8NN600FA is rated to 200 bar maximum pressure — significantly higher than the 160 bar rating of the smaller Ford pump variants. This higher pressure rating reflects the demands of the heavier tractor models in this series, which may use front-loaders, high-capacity three-point lift systems, and multiple remote cylinder circuits simultaneously. A 33 ml/r pump at 2,000 rpm delivers approximately 66 litres per minute of theoretical flow, providing fast hydraulic response even under heavy load.

When diagnosing hydraulic problems on these larger Ford models, check the system relief valve setting before assuming the pump has failed. An incorrectly set or stuck-open relief valve will cause the same symptoms as a worn pump — loss of pressure and slow cylinder operation — while the pump itself remains serviceable. Contact us for diagnostic guidance.

Ford 5610–8210 Hydraulic Architecture

The mid-range to heavy Ford tractors in this group typically use a tandem or single-section pump arrangement mounted to the engine or transmission. On the 7810, 7910, and 8210 — the largest models in the list — the hydraulic system must supply sufficient flow for the three-point draft control, remote circuits, power steering, and in many configurations a front-end loader. The 33 ml/r pump is correctly sized for this combined demand.

When replacing the pump on a tractor fitted with a front-end loader, ensure the loader is lowered and all hydraulic pressure is relieved before disconnecting any lines. The large-bore Φ28 mm discharge port carries high-pressure fluid at volume — an accidental disconnection under pressure is dangerous. Always depressurise the circuit before working on it. Contact us if you need guidance.
