John Deere RE73947 / 30+14 cc Two-Section Hydraulic Gear Pump Replacement

Identification before quotation

If the existing machine’s service documentation lists RE73947 / 30+14 cc, check the full cross-reference RE73947; RE72058; RE69866. The serial range and original pump details still determine the final match.

No specific tractor serial ranges are established here for RE73947 / 30+14 cc. Use the parts manual and existing hardware to complete the application check.

Technical specifications

How to compare pump sizes

The 30/14 ml/rev notation must stay split during selection. It is not sufficient to add the displacements and order a single pump with the same summed capacity.

Within the comparison set, 1986963C1 / 9 cc lists 9.0 ml/rev and 140 bar. That is a useful limit check for the RE73947 / 30+14 cc hydraulic request, not permission to alter the tractor’s original pump rating.

Flow-control behavior is not defined by this parts entry. Confirm the tractor valve and circuit characteristics independently.

The stated speed is 700–2500 rpm. Before commissioning, verify the engine accessory drive ratio and that normal operating conditions do not exceed this listing.

A useful alternative reference check

As a sanity check, compare this entry with John Deere 1986963C1 / 9 cc. A near-identical picture is weaker evidence than distinct OEM numbers, connection shapes and the stated CCW rotation.

Only the relevant tractor variant and mounting geometry can settle a close call between two replacement choices.

Hydraulic plumbing and rotation

Checking rotation for RE73947 / 30+14 cc requires a known viewpoint. Record whether the shaft was observed from the coupling face, as the listing gives counterclockwise.

For hose matching, write down both port specifications: feed Ø32, discharge M27×2 & M22×1.5. Thread class and sealing face matter as much as nominal size.

Hydraulic cleanliness and coupling fit

Before the first start, rotate the drive in the correct direction by the approved maintenance procedure and verify RE73947 / 30+14 cc receives oil. Run unloaded initially and monitor for abnormal sound or leakage.

Make the clockwise/counterclockwise check explicit in the workshop instruction: RE73947 / 30+14 cc is CCW.

A clear hydraulic pump RFQ

If replacing a failed John Deere unit, share its stamped identifier, gearbox or engine-side drive photo and port measurements. The listed 250 bar pressure is not a substitute for the machine’s actual relief setting.

Let the quotation identify any uncertainties in compatibility before manufacturing begins.

Frequently checked details

Is the John Deere tractor name sufficient for ordering?

No. Confirm the exact pump removed from the tractor, its drive-side rotation and its connection geometry.

What does the 250 bar pressure value represent?

It is the maximum catalogue entry for this model, not proof that the tractor circuit or hoses may safely operate at that pressure.

Ordering, samples and shipping terms

Order quantities are set according to pump type and total order value. A small order of 1–2 pieces can be considered at a higher unit price; new customers may request 1–5 samples when the item is suitable. Mixed-model orders are available, normally with a combined order value of approximately USD 1,500.

Typical production schedules are 10–25 working days for standard items, 20–45 working days for customized components, and 45–120 working days for project equipment. Usual delivery terms are EXW, FOB, CIF and DAP. FCA, CFR, CPT, CIP and DDP can be discussed for specific shipments. Confirm the final schedule and terms with the quotation.
