Why the Same Part Number Ships in Multiple Variants

A single base solenoid design carries five or more part numbers across engine generations, and not every variant shares the same port orientation or connector type.

Cross-reference tables copied between sellers often carry errors forward. A part number that matches your machine model on paper may still arrive with the oil port rotated ninety degrees from where your fuel pump expects it [NEED_CITE: fuel injection pump solenoid variant identification across equipment generations]. That mismatch does not show up in a catalog search — it shows up on the shop floor when the machine is already apart and waiting. I have had solenoids arrive on site with the correct identifier stamped on the label, only to find the port position was wrong for the specific Stanadyne pump build installed. The 12V Fuel Injection Pump Shutoff Solenoid for John Deere Perkins cross reference list on this page has been verified against specific engine serial ranges, not just model numbers, to catch these variant differences before the part ships.

Fitment Verification Across Superseded Part Numbers

The identifier list for this 12V Fuel Injection Pump Shutoff Solenoid for John Deere Perkins cross reference covers RE62240, RE37089, AR48219, AR51796, and AR90340. Each of these numbers was assigned to different production runs and engine families. RE37089, for instance, superseded AR90340 on later John Deere 4239T and 6466D builds, but the physical difference between the two is not always a direct swap — the electrical connector and port clocking can differ. Providing your engine serial number or a photograph of the existing solenoid allows the technical team to confirm which specific variant from the cross-reference list matches your fuel pump.

Port Position, Connector Type, and Mounting Pattern

The critical fitment check on a stop solenoid is not the thread size — it is where the port faces relative to the pump body, what type of electrical connector is on the pigtail, and whether the mounting flange bolt pattern aligns with your existing holes. A ninety-degree rotation in port position means the solenoid cannot physically seat against the pump housing. Connector variants include blade-type and circular pin configurations within the same part number family [NEED_CITE: Stanadyne and Roosamaster fuel pump solenoid connector variants]. Before any bulk commitment, request a sample unit and physically compare port orientation, connector pin count, and mounting hole spacing against your removed unit.

Reading the Specifications for Real-World Performance

The IP67 sealing rating means this solenoid withstands pressurized water jets and temporary submersion — critical for harvesters operating through washdowns and loaders working in muddy grading conditions. Class H insulation holds stable at temperatures up to 180°C, which matters when the solenoid sits directly against a fuel pump body radiating heat from a turbocharged diesel. The ±0.05 mm dimensional tolerance ensures the solenoid plunger engages the shutoff lever without binding or leaving excess play that causes erratic fuel cutoff. Zinc-nickel plating at 15 μm thickness provides corrosion protection in high-salinity and high-humidity environments, far exceeding standard zinc plating for the same exposure conditions.

The Hidden Cost of a Variant Mismatch

Ordering by part number alone without verifying the variant means risking a solenoid that threads in but will not seal, or seals but cannot connect electrically. The machine sits disassembled while the correct part is sourced, often on an emergency freight timeline. Worse, a solenoid that partially fits can be forced into place, leading to premature seal failure, fuel leakage past the O-rings, or erratic shutoff behavior that damages the injection pump internals [NEED_CITE: fuel injection pump damage from incorrect solenoid fitment]. The downtime from a misidentified variant routinely exceeds the cost of the part itself many times over.

Why Source This Stop Solenoid Through XUNPO

Own production on selected part lines combined with qualified sourced supply means every stop solenoid ships under one account and one warranty. The eight product categories allow you to consolidate gaskets, filters, and seal kits for the same fuel system repair into a single consignment. Minimum order is one piece — no MOQ blocking an emergency single-unit replacement. The Guangzhou warehouse carries stock on high-turnover items for fast dispatch. Part identification is available from a part number, machine model, photograph, or nameplate image. Cross-reference verification covers superseded and alternate numbers across the John Deere, Perkins, and GM engine families. Sample supply is available for fitment confirmation before you commit to a bulk order.

Documentation & Verification

• Commercial invoice and packing list with each stop solenoid part number and cross-reference clearly itemized
• Part compatibility and cross-reference sheet noting RE62240, RE37089, AR90340 variants as reference only
• Quality inspection record covering ±0.05 mm dimensional check and 12V functional actuation test
• Six-month warranty terms against manufacturing defects included with every shipment
• Packing photographs showing each solenoid in anti-static foam before carton sealing
• HS code and customs documentation support provided for international clearance

Fitment Check Before Installation

• Compare port clocking position on the new solenoid against your removed unit before any gasket or O-ring installation
• Verify electrical connector pin count and type match the existing wiring harness plug on the machine
• Check dual O-ring seating in the elastomer housing for nicks or deformation from transit
• Confirm mounting flange bolt holes align with the fuel pump body without force or bracket modification
• Test 12V actuation with a multimeter before final assembly to verify plunger travel and shutoff lever engagement
• If port position or connector type does not match, halt installation and contact the technical team with photographs

Send Your Machine Details for Fitment Confirmation

Provide your John Deere or Perkins machine model, engine serial number, or a clear photograph of the existing solenoid and its nameplate. The technical team will verify which variant from the RE62240, RE37089, or AR90340 cross-reference list matches your specific fuel injection pump build, confirm port orientation and connector type, and advise whether a sample unit is recommended before you place a larger order.

Frequently Asked Questions

Q: How do I confirm which of the five listed part numbers applies to my specific engine? A: Each part number maps to specific engine serial ranges and fuel pump variants. Provide your engine serial number, machine model, or a photograph of the existing solenoid label. The technical team cross-references the serial against known variant splits in the John Deere 4239/6466 and Perkins 1004/1006 families to confirm which exact identifier matches your build.

Q: My old part number is no longer listed — is there a verified superseded replacement? A: Yes. The cross-reference list includes superseded numbers mapped to their current equivalents. AR90340, for example, was superseded by RE37089 on certain production runs. Submit your old number for verification — the team will confirm whether the superseded replacement shares the same port orientation and connector type as your original unit.

Q: The same part number appears with different connector types — how do I know which variant I need? A: Variant differences within a single base part number are common across equipment generations. A photograph of your existing solenoid connector and the fuel pump nameplate allows the team to identify the correct blade-type or circular pin configuration for your specific pump build before the part ships.

Q: I only have a machine model, no readable part number — can you still identify the correct solenoid? A: Yes. Machine model combined with production year or engine serial range narrows the correct variant from the cross-reference list. If the nameplate is worn or painted over, provide a photograph of the fuel pump body and solenoid mounting area — the team can often identify the pump platform and match the solenoid variant from visual cues.

Q: Can I order one sample to confirm fitment before placing a larger order? A: Yes. Single-piece orders are accepted with no minimum quantity requirement. Ordering a sample allows you to physically verify port position, connector type, and mounting pattern against your machine before committing to a bulk quantity for a mixed fleet.
