Product overview
John Deere Tractor Hydraulic Gear Pumps manufacturing starts with confirmed technical requirements.
Review machine application, displacement, working pressure, port threads, and rotation direction before requesting a quotation.
The tandem entry covers OEM references RE73947, RE72058, and RE69866. Its 30/14 ml/r rating means two gear sections of 30 and 14 ml/r share one drive shaft, letting a single mounting point feed two circuits at different flows. Its discharge side is listed as M27*2 and M22*1.5, matching the two sections, and the catalogue did not print a feed port value. The 9.0 ml/r entry covers OEM references 1986963C1 and 05104153, is rated 140 bar over 500-3000 r/min, and uses Φ20 feed and Φ15 discharge ports. With only two entries, this is the smallest tractor brand group in the catalogue. Buyers should be prepared to supply a sample or drawing for machines outside these two part numbers.

Selection guidance
How to specify a john deere tractor hydraulic gear pumps for quotation.
Use equipment model, OEM reference numbers, rotation direction, and port threads to verify exact replacement compatibility.
1. Confirm the OEM reference number first. JOHN DEERE tractors of the same model year can carry different pump part numbers depending on whether the machine has factory hydraulic remotes, a loader valve, or power steering priority. 2. Match displacement, not just the mounting flange. Nominal displacement in ml/r sets flow at a given engine speed. A larger displacement raises flow but also raises drive torque and heat load. 3. Confirm rotation direction. Catalogue entries are listed as Right (Clockwise) or Left (Anti-clockwise) as viewed from the drive end. A pump run backwards will not prime. 4. Check both port threads before ordering. The catalogue mixes UNF, metric fine (M18x1.5, M16x1.5, M14x1.5), BSP (G), and NPT threads within the same brand family. Adapters add leak points and cost. 5. Match pressure capability to the relief setting. Maximum pressure in the catalogue is the pump rating, not the system setting. The relief valve normally limits working pressure below that figure. 6. Check the controlled flow rate where listed. Some entries include a controlled flow rate in L/min, which matters for steering and constant-flow circuits.

Quality Control & Inspection Matrix
Engineering Evidence & 100% Inspection for John Deere Tractor Hydraulic Gear Pumps.
Overseas procurement teams require verifiable technical data, not unsupported claims. Every production batch at ZhongYi is inspected against approved CAD blueprints and international standards (DIN, AGMA, ISO).
Component-Specific Quality Focus:
The supplier holds an IATF 16949:2016 certificate (certificate number DB00992, IATF registration number 0454540, issued 26/07/2022, expiring 25/07/2025). IATF 16949 covers automotive-sector quality management system requirements; it is not a product type approval and does not by itself certify any individual pump model. The catalogue does not publish material grades, heat treatment specifications, volumetric efficiency test data, or endurance test results. Buyers who need those should request them directly rather than assume they exist: dimensional inspection reports for the mounting flange, shaft, and port threads; material certificates for the housing and gear set; volumetric and overall efficiency test curves at rated speed and pressure; sample pumps for fitment and bench testing before a production order; and confirmation of the drawing revision used for manufacture. Because the certificate expiry date has passed relative to many buying cycles, ask for the current certificate before qualifying the supplier.
