GBC-RE73947 — John Deere Tractor Hydraulic Gear Pump Replacement RE73947

John Deere’s 2000-series and 3000-series tractors produced through the 1980s and 1990s established a strong foothold in Australian broadacre farming. The 2355, 2555, 2755, and 2955 were particularly well-suited to the scale of Australian grain production — large enough to pull 5–7 metre cultivators and air seeders, yet manageable enough for solo operation on family farms. The 3000 series — the 3055, 3155, and 3255 — extended the range further into the 100–130 hp territory needed for larger broadacre operations. These tractors are still widely in service across the Australian wheat belt and grain regions, and hydraulic pump replacement is a regular service requirement as accumulated hours accumulate on the hydraulic circuit.

The {sku} is an aftermarket replacement hydraulic gear pump covering the John Deere 2155–3255 series, cross-referencing OEM part numbers RE73947, AR94661, and AR103033. Having three OEM cross-references confirms fitment across the full 2155–3255 model range. Visit the GBC homepage for the full JD and multi-brand tractor hydraulic pump range.

OEM Reference Numbers — RE73947, AR94661, AR103033

John Deere’s parts supersession system means that a pump may be listed under multiple active and superseded references. AR94661 and AR103033 are earlier references that were superseded by RE73947 as the primary service number. All three confirm fitment of the {sku}. Match any one of these three references against your existing pump to confirm correct part selection.

Technical Specifications

John Deere Legacy Fleet in Australian Broadacre Farming

Australian broadacre farming operations that built their equipment fleets in the 1980s and 1990s often anchor around John Deere 2000 and 3000 series tractors that remain in service as reliable second tractors on properties that have since upgraded to larger primary machines. These tractors — 30–40 years old in many cases — are maintained to working standard rather than to original condition, and the focus is on reliable, cost-effective parts supply. For the operators of these machines, the choice between an OEM pump at premium pricing with uncertain lead time versus an aftermarket {sku} at lower cost and shorter delivery is straightforward.

John Deere specialist workshops and JD-brand agricultural dealers also stock aftermarket alternatives for the 2000–3000 series as a practical customer service offering. Stocking the {sku} allows these workshops to provide rapid turnaround on hydraulic pump replacement without waiting for OEM supply. Contact us for JD dealer pricing and availability.

RE73947 Pump Replacement Procedure for JD 2000–3000 Series

On John Deere 2155–3255 series tractors, the hydraulic gear pump is accessible from the transmission cover after removal of any rear shields or guards. The pump is spigot-located and flange-bolted to the transmission case. Confirm that the drive shaft engages correctly with the transmission drive dog before tightening the mounting bolts — incorrect engagement depth will result in premature pump drive wear or immediate failure.

Use John Deere specification Hy-Gard or equivalent multi-viscosity hydraulic/transmission oil when refilling the sump. Pre-fill the {sku} pump through the inlet port and run at low idle to prime before applying implement load. Change the hydraulic filter at the same time for best long-term results.
