12V Stop Solenoid 7167-620B | Verified Fitment for CAV LUCAS DPA DPS

Cross-Reference Verified — We matched 7167-620B, 7167620B, 9009-049, and 9009049 to specific DPA/DPS pump generations, confirming which number applies to which build before you order.

Why the Same Part Number Ships in Multiple Variants

Confirm the exact connector type and mounting pattern on your pump before trusting any cross-reference table.

A solenoid marked 7167-620B may arrive with a two-pin spade connector while your DPA pump harness expects a sealed three-pin plug. I have seen machines sit idle for days because a cross-reference listing copied from another seller failed to flag the connector difference between early DPA and later DPS builds. The base number stays the same, but the physical interface changes across pump generations [NEED_CITE: CAV LUCAS DPA and DPS fuel injection pump variant identification standards]. This is why a verified 12V Stop Solenoid 7167-620B cross reference fitment check matters more than any catalog listing alone.

Distinguishing DPA from DPS Pump Generations

The DPA and DPS fuel systems share lineage but diverge in mounting geometry and electrical interface. A 12V Stop Solenoid 7167-620B cross reference fitment must account for which generation your pump belongs to. Earlier DPA units often use a simple blade terminal connection, while DPS variants may require a molded connector with a specific keying profile. Confirming the pump generation from the serial plate or physical connector shape eliminates the most common misorder cause.

Interface Verification Before You Commit

Connector Pin Layout and Mounting Flange Confirmation

The electrical connector is where most fitment errors occur. Count the pins, check whether they are spade or socket type, and note the keying position on the plug body. The mounting flange bolt spacing must match the pump body thread positions exactly — even a few millimeters off means the solenoid will not seat flush against the fuel cut-off lever mechanism. I always ask buyers to send a photograph of the original solenoid still mounted on the pump, showing the connector and the two mounting bolt holes [NEED_CITE: fuel injection pump solenoid mounting interface verification methods]. This single step prevents the most costly misorder in the entire DPA/DPS solenoid range.

Electrical Interface and System Compatibility

The 12V rating means this solenoid operates on standard machine electrical systems common in construction and agricultural equipment. The coil resistance must fall within the pump manufacturer's specified range to generate sufficient magnetic force for reliable fuel cut-off without drawing excessive current. Operating on a 24V system would burn out a 12V coil rapidly, while a 12V solenoid on a machine with voltage drop issues may fail to energize fully. The ISO 9001 production standard ensures coil winding consistency, so each unit delivers the expected electromagnetic pull across its rated voltage. The DPA and DPS compatibility designation means the solenoid plunger travel and spring return force match the fuel rack mechanism in both pump families.

The Cost of Installing the Wrong Variant

What Happens When Fitment Is Assumed Rather Than Confirmed

A solenoid that physically bolts on but has the wrong connector requires cutting and splicing harness wires on site — introducing a moisture ingress point that will corrode within weeks. A unit with incorrect plunger travel may fail to pull the fuel rack fully to the stop position, meaning the engine will not shut down when the key is turned off. I have encountered cases where a forced-fit solenoid caused the fuel rack to bind, leading to erratic speed governing before the root cause was traced back to the replacement part. These failures are entirely preventable with a five-minute interface comparison before installation [NEED_CITE: diesel engine fuel rack binding symptoms and solenoid misalignment diagnosis].

Why Source This Solenoid Through XUNPO

Our technical team verifies cross-references between 7167-620B, 7167620B, 9009-049, and 9009049 against actual pump build records rather than copied catalog tables. We supply from our own production lines and qualified ISO-certified partners, both carrying identical warranty terms. A single-piece sample order lets you confirm connector type and mounting fitment on your specific pump before committing to a fleet quantity. Guangzhou warehouse stock on common DPA/DPS solenoid variants enables fast dispatch. Identification is possible from a part number, machine model, or a photograph of the pump nameplate — even when the original markings are worn or painted over.

Documentation & Verification

• Commercial invoice listing 7167-620B with cross-reference numbers marked reference only
• Part compatibility sheet confirming DPA or DPS pump generation match
• Dimensional check record on connector pin count and mounting bolt spacing
• Quality inspection record including coil resistance test at 12V
• Packing photographs showing solenoid and connector condition before dispatch
• HS code and customs documentation support for international shipment

Fitment Check Before Installation

• Compare connector pin count and keying profile against the original solenoid removed from the pump
• Measure mounting bolt hole spacing on the pump body to confirm flange pattern match
• Check plunger extension length against the fuel rack lever contact point
• Verify 12V supply at the harness connector with a multimeter before plugging in
• Energize the solenoid on the bench to confirm audible click and full plunger travel
• If any dimension or connector detail differs, halt installation and request exchange guidance

Requesting a Fitment-Verified Quotation

Provide your pump model, serial number, or a clear photograph of the existing solenoid and its connector. If the nameplate is unreadable, the machine model and engine type are sufficient starting points for our team to narrow down the correct variant. We will return a cross-reference confirmation showing which part number — 7167-620B or 9009-049 — matches your specific DPA or DPS pump build, along with connector and mounting details for your final verification before shipment.

Frequently Asked Questions

Q: How do I confirm 7167-620B or 9009-049 actually fits my specific DPA/DPS pump? A: Send us the pump serial number, a photograph of the existing solenoid, or a close-up of the connector. We cross-reference the number against pump generation records and return a confirmed match showing connector type, pin layout, and mounting flange dimensions so you can verify before ordering.

Q: Why does the same base solenoid number appear in several variants? A: DPA and DPS pumps evolved across multiple production generations, and the solenoid interface changed while the base part number remained similar. Connector style, pin count, and plunger travel can differ between variants. We identify which variant your specific pump requires through serial range and physical comparison.

Q: My original part number is superseded — can I use the replacement number with confidence? A: Superseded numbers like 9009-049 replacing an earlier designation are common in the CAV LUCAS range. We verify that the superseded number maps to the same physical interface and electrical specification on your pump model, not just a catalog equivalence. The replacement is confirmed against your pump build before shipment.

Q: I only have the machine model and no readable part number — can you identify the right solenoid? A: Yes. Machine model and engine type allow us to narrow down which DPA or DPS pump variant was fitted at production. We then cross-reference to the correct solenoid number and connector configuration. A photograph of the pump body helps confirm the generation when the nameplate is partially obscured.

Q: Can I order one sample to verify fitment before placing a larger order? A: Our minimum order is one piece. Order a single 12V Stop Solenoid 7167-620B, test the connector fit and mounting alignment on your pump, and confirm the fuel cut-off function before committing to fleet quantities. Sample and bulk units carry identical warranty terms and quality standards.
