AM876266 AM876207 Fuel Pump Replacement for Yanmar 3TNV88 John Deere

Cross-Reference Verified — AM876266 and AM876207 mapped to identical physical units across Yanmar 3TNV88 and extended John Deere model ranges.

Technical Specifications

Application Suitability

Why the Same Part Number Ships in Four Variants

Superseded numbers and application-specific builds mean one base identifier can resolve to several physical configurations.

Buyers holding a worn nameplate often find that AM876266 (cross-reference only) appears across dozens of John Deere tractors, mowers, and the E18ZS excavator, yet the actual pump delivered may have a different connector layout or port orientation depending on the engine serial block it was built for. I once processed an order where the buyer specified a Yanmar 3TNV88 pump for a mower application, but the engine serial fell into a production run where the fuel outlet was rotated compared to earlier builds. The pump bolted on but the fuel line would not reach without bending. That mismatch cost the site two days of unplanned downtime while a replacement was sourced [NEED_CITE: Yanmar engine serial range variation and fuel system component differences].

A 12V Fuel Pump for Yanmar 3TNV88 / John Deere cross reference AM876266 must be verified against the specific machine model and engine serial before dispatch, not ordered solely on the basis of a part number lookup in a generic catalogue.

Engine Serial Coverage and Variant Boundaries

The Yanmar 3TNV88 sits within a broader engine family that includes the 3TNV84, 3TNV76, 3TMN72, 4TNV88, and several turbocharged and high-altitude variants. Each of these engines may share the same base fuel pump design but differ in port angle, connector pin count, or mounting bracket geometry. The 12V Fuel Pump for Yanmar 3TNV88 / John Deere cross reference AM876266 covers the core serial range, but confirming whether a specific engine build falls inside or outside that range requires matching the serial prefix against the cross-reference sheet.

Connector Type, Port Orientation, and Mounting Pattern

The electrical connector on this fuel pump must match the machine wiring harness without requiring adapter modifications. Terminal configuration and pin layout vary between John Deere tractor and mower applications even when the base part number is identical. Port orientation — the angle at which the fuel inlet and outlet face relative to the mounting flange — is the single most common source of fitment failure when a pump is ordered by number alone. Verifying these three interfaces against the existing unit or the machine wiring diagram eliminates the majority of installation problems [NEED_CITE: electrical connector and fuel port verification standards for mobile equipment].

Reading the Specifications That Matter

The 12V rating defines the operating voltage for the pump motor; running this unit on a 24V system will cause immediate failure of the internal windings. The new aftermarket condition means no prior wear history and no unknown rebuild provenance, which matters because fuel pump diaphragm fatigue is not visible on external inspection. ISO-certified sourcing ensures the manufacturing facility maintains documented process controls for dimensional tolerances on the mounting flange and port threads. The 3-12 month warranty window covers premature failure under normal operating conditions.

The Cost of Skipping Fitment Verification

Ordering a fuel pump by part number alone and discovering a port orientation mismatch on site means the machine stays down while a replacement is arranged. Return shipping on a single unit is often not economical, so the incorrect pump sits on a shelf while an emergency order is placed at whatever terms the available supplier demands. For a mower fleet or a compact excavator on a job site, each day of unplanned downtime carries costs that far exceed the component price. Verification before dispatch is the only reliable way to prevent this cycle [NEED_CITE: cost of unplanned equipment downtime in construction and landscaping operations].

Why Source This Fuel Pump Through XUNPO

Own production on selected lines plus qualified sourced supply, both under one account and one warranty, means you do not manage separate vendor relationships for different part categories. Eight product categories allow a complete fuel system job — pump, filters, lines, seals — to ship as one consignment. Minimum order from one piece supports single-unit emergency replacements without forcing bulk commitments. Guangzhou warehouse stock enables fast dispatch on common items. Part identification from number, machine model, photograph, or nameplate image covers situations where the original label is worn or painted over. Cross-reference verification covers superseded and alternate numbers including AM876207, 2803-3000, and 28033000. Sample supply is available for fitment confirmation before a fleet-level bulk order.

Documentation & Verification

• Commercial invoice and packing list with part number and machine model reference
• Cross-reference sheet mapping AM876266, AM876207, 2803-3000 (reference only) to specific engine serial ranges
• Dimensional check on port orientation and connector pin layout before dispatch
• Quality inspection record covering voltage test and leak test at rated pressure
• Warranty terms document specifying coverage period and claim procedure
• Packing photographs showing unit condition and protective packaging before sealing

Fitment Check Before Installation

• Compare port orientation on the new pump against the removed unit before connecting fuel lines
• Verify electrical connector pin count and terminal layout against the machine wiring diagram
• Check mounting bolt pattern spacing against the existing flange holes on the engine block
• Confirm fuel line routing does not require bending or stretching after the pump is bolted in place
• Run a brief priming cycle and inspect all connections for leaks before returning the machine to service

Requesting Fitment Confirmation

Provide the John Deere machine model and engine serial number, or send a photograph of the existing pump showing the connector and port layout, so the technical team can verify cross-reference accuracy and confirm the correct variant before the order ships.

Frequently Asked Questions

Q: How do I confirm this fuel pump fits my Yanmar engine when the nameplate is unreadable? A: Send a photograph of the existing pump showing the mounting flange, electrical connector, and fuel port positions. The technical team matches these visual features against the cross-reference database for Yanmar 3TNV88 and related engine families to identify the correct variant without relying on the nameplate alone.

Q: AM876266 and AM876207 look different online — are they the same pump or different variants? A: Both numbers resolve to the same physical fuel pump unit in the verified cross-reference. Differences in online images usually reflect photograph angles or listings for different application groups. Confirming against the engine serial number removes any remaining ambiguity before the order is placed.

Q: My John Deere model is listed but the engine serial is from a different production year — will it still fit? A: Production year alone does not determine fitment; the engine serial block and the specific build configuration matter. Providing the serial number allows the technical team to confirm whether that production run uses the same port orientation and connector type covered by this cross-reference.

Q: Can I get a sample to test fitment before ordering for the whole fleet? A: Sample supply is available for first-time fitment verification. Install the sample on one machine, confirm port alignment, connector match, and operational performance, then proceed with confidence on the bulk order covering the remaining fleet units.

Q: What if the cross-reference table I found elsewhere shows a different number for my machine? A: Cross-reference tables copied between sellers often carry errors forward or omit superseded numbers. Submit your machine model and the number you found, and the technical team will verify it against the master cross-reference covering AM876266, AM876207, 2803-3000, and 28033000 (reference only) to confirm or correct the match.
