Why the Same Part Number Ships in Multiple Variants

Cross-reference tables copied between sellers often carry forward errors that only surface during physical installation.

Superseded part numbers and variant differences within the same base number create fitment uncertainty. A solenoid labeled 7167-620B may have different connector pin orientations or mounting bolt spacing depending on the production batch and target pump model. Without verifying the specific injection pump serial range, buyers risk receiving a component that requires wiring modifications or fails to seat properly against the pump housing [NEED_CITE: diesel injection pump solenoid variant identification standards].

Matching Solenoid to Injection Pump by Serial Range

The 12V Stop Solenoid for DPA DPS injection pump cross reference requires matching not just the base part number but the specific pump variant. DPA and DPS pumps evolved across multiple generations, with changes in solenoid mounting depth, plunger diameter, and electrical connector configuration. Providing the injection pump model and serial number allows precise identification of which solenoid variant fits your machine, eliminating trial-and-error fitment attempts that delay equipment return to service.

Interface Verification Before Installation

Physical interface differences between nominally interchangeable solenoids include connector pin count, mounting bolt circle diameter, and plunger stroke length. A solenoid may share the same electrical specifications and mounting pattern but have a plunger that does not fully engage the fuel rack, resulting in incomplete fuel cut-off or erratic engine shutdown behavior. Dimensional tolerance of ±0.05 mm ensures proper seating, but only physical comparison against the removed unit or measurement of the pump cavity confirms correct variant selection [NEED_CITE: diesel fuel system component interchange verification procedures].

Electrical and Sealing Specifications for Field Reliability

The 12V actuation voltage suits standard mobile equipment electrical systems, while the <25 ms response time ensures immediate fuel cut-off when the ignition switches off. Class H insulation rated to 180°C handles heat soak from adjacent exhaust components and engine bay temperatures. Dual NBR O-rings provide IP67 sealing against diesel fuel exposure, washdown water ingress, and dust contamination typical in mining and demolition environments. The stainless steel plunger with HRC 48–52 hardness resists wear from repeated actuation cycles and fuel lubricity variations across different diesel formulations.

The Cost of Fitment Errors on Downtime

Installing a solenoid with incorrect plunger length or connector type means the machine remains non-operational while a replacement ships. Even when a mismatched solenoid physically bolts to the pump, improper fuel rack engagement causes unreliable shutdown, leaving operators unable to secure the engine during maintenance or emergency stops. Return shipping, re-ordering, and extended equipment idle time compound the initial procurement delay into measurable project losses [NEED_CITE: construction equipment downtime cost factors for fuel system repairs].

Why Procurement Verification Matters Here

Guangzhou warehouse stock enables rapid dispatch on common solenoid variants, but part identification from machine model, photograph, or nameplate image ensures the correct unit ships. Cross-reference verification covers superseded and alternate numbers including 7167620B and 9009049, catching errors that generic interchange tables miss. Sample supply allows fitment confirmation on your specific pump model before bulk commitment, preventing fleet-wide rollout of an incompatible component. Technical team availability for compatibility and grade confirmation addresses variant questions that online catalogs cannot resolve.

Documentation & Verification

• Commercial invoice and packing list specifying solenoid variant and cross-reference numbers
• Part compatibility and cross-reference sheet marking OEM numbers as reference only
• Quality inspection record with dimensional measurements and electrical continuity test
• Warranty terms covering manufacturing defects for six months from delivery
• Packing photographs showing individual retail box with anti-static foam cushioning
• HS code and customs documentation support for international shipment clearance

Fitment Check Before Installation

• Compare mounting bolt circle diameter and hole spacing against removed solenoid or pump housing
• Verify connector pin count and orientation match existing wiring harness plug configuration
• Measure plunger extension length to ensure proper fuel rack engagement without binding
• Check dual NBR O-ring condition and apply light diesel fuel film before insertion
• Test 12V actuation with multimeter before final assembly to confirm electrical function
• If dimensional mismatch discovered, halt installation and request cross-reference re-verification

Request Fitment Verification

Provide your injection pump model, serial number, or photographs of the existing solenoid and connector to receive confirmed compatibility data. Machine nameplate images showing model and production date assist in identifying superseded part numbers. Sample orders available for physical fitment testing before committing to fleet quantity purchases.

Frequently Asked Questions

Q: How do I confirm this solenoid fits my specific DPA/DPS injection pump model? A: Provide the injection pump model designation and serial number range. We cross-reference against verified compatibility sheets that account for variant differences in connector type, plunger length, and mounting pattern across pump generations. Photographs of your existing solenoid and nameplate accelerate identification. Sample supply available for fitment confirmation before bulk commitment.

Q: What is the difference between 7167-620B and 9009-049 — are they interchangeable? A: These numbers reference the same functional solenoid but may indicate different production variants or superseded designations. Physical dimensions, electrical specifications, and mounting patterns require verification against your specific pump model rather than assuming direct interchange. We confirm compatibility through cross-reference validation covering dimensional tolerances and connector configurations before shipment.

Q: My existing part number doesn't match either number — can you cross-reference it? A: Superseded and alternate part numbers accumulate across equipment generations and distributor catalogs. Send the number from your existing solenoid along with injection pump model details. We verify against comprehensive cross-reference databases covering discontinued numbers, manufacturer revisions, and aftermarket equivalents to identify the correct current replacement variant.

Q: Can I order one sample to test fitment before committing to a larger quantity? A: Single-piece orders available with no minimum quantity requirement for initial fitment validation. Sample supply allows physical installation testing on your specific pump configuration before committing to fleet-wide procurement. This prevents bulk orders of incompatible components and confirms dimensional and electrical compatibility in actual working conditions.

Q: What if the connector type or mounting pattern doesn't match on arrival? A: Halt installation immediately and contact us with photographs showing the mismatch details. Our pre-shipment verification process includes cross-reference confirmation, but variant differences occasionally surface only during physical comparison. We arrange replacement dispatch and investigate the identification discrepancy to prevent recurrence on subsequent orders for your equipment fleet.
