0445120127 Common Rail Injector for Weichai WP12 Heavy Trucks

0445120127 Weichai WP12 Injector Product Description

The 0445120127 purchasing record centers on Weichai WP12 heavy-duty engines, where truck rating and emissions build matter as much as the engine family. Shacman, Shaanxi and Foton references can guide the search, but the approval should preserve Weichai 612630090012 and the installed injector marking. A truck model alone cannot identify every WP12 calibration.

The injector uses nozzle 0433172039 / DLLA143P1696 and valve set F00RJ01727. These references also help differentiate it from WD10 and WP10 products that appear in the same distributor inventory. 0445120389 is associated with the same nozzle in WP12 Euro III records, so a buyer should determine whether it is a verified replacement relationship for the specific engine rather than assuming unrestricted interchange.

Long-haul and construction-haul fleets often request several units after contamination or a set-level diagnosis. The RFQ should say whether the order is a complete engine set, a depot stock replenishment or a single-failure replacement program. That context informs lot control, correction-data handling and receiving labels without inventing a fitment promise beyond the confirmed engine.

0445120127 Heavy-Truck Rating and Supply Control

Provide the WP12 engine serial, power rating, truck or equipment model, 612630090012 and images of the old injector. If the maintenance system contains both 0445120127 and 0445120389, show which number is physically installed. Elecdura can then quote the complete injector group while keeping the supersession decision visible for the purchaser.

MOQ is 6–12 pcs, with 7–15 Days delivery, Neutral / Customized Packaging and a 12-month warranty. For a fleet set, customized labels can identify engine allocation and carton sequence. Protect each injector's correction information and avoid combining WP12 and WD10 stock under generic Weichai packaging.

Receiving inspection should compare all body labels, sealing caps and connectors before the shipment is divided among workshops. The installer must use the approved WP12 service method for correction data and fuel-system cleanliness. A correctly numbered injector can still be mishandled if contamination control or commissioning instructions are ignored.

0445120127 Weichai WP12 Heavy-Truck Buyer FAQ | B2B Buyer FAQ

Which Weichai number should accompany 0445120127?

Use 612630090012 when it appears in the engine or parts record, and retain 0445120127 as the lead injector identity. Provide the old-unit photograph and WP12 engine serial. The combination allows a supplier to control the order even when a truck dealer system emphasizes the Weichai number rather than the injector manufacturer format.

Is 0445120389 automatically interchangeable?

No. It is associated with a related WP12 configuration and the same nozzle reference in public application material, but interchange must be confirmed for the exact engine rating and calibration. Show both numbers from the service history, identify the physically installed unit and obtain approval before one number replaces the other.

Why does the WP12 power rating matter?

WP12 engines appear across several truck outputs and production configurations. The family name alone does not prove that fuel-system calibration and injector assignment are identical. Add the rating, serial and emissions information to the RFQ so the parts team can separate a verified 0445120127 requirement from a visually similar Weichai injector.

How should a complete engine-set order be described?

State the cylinder count, total pieces, whether one matched lot is required and the engine or truck allocation. Include correction-data expectations and packaging labels. If the order includes reserve stock beyond one set, separate that quantity so receiving can preserve traceability instead of mixing workshop-assigned and warehouse units.

Can DLLA143P1696 approve the full injector?

It is an important technical checkpoint but not a complete approval. The nozzle code does not define every body, connector, valve and calibration detail. Confirm 0445120127, F00RJ01727, 612630090012 and the original assembly. A nozzle-only match is suitable for a component discussion, not an automatic complete-unit substitution.

What should be checked after a fleet contamination event?

In addition to confirming injector identity, the service network should address the fuel tank, filtration, rail and line cleanliness under the engine manufacturer's procedure. Replacement injectors should remain sealed until installation. Record correction data and lot identity so any later diagnosis can distinguish a fuel-system issue from a particular supplied unit.

How can packaging distinguish WP12 from WD10 inventory?

Use the full injector number, Weichai OE, engine family and a warehouse color or bin code that does not cover the manufacturer's markings. Never rely on one shared product image. WP12 0445120127 stock should be physically separated from WD10 groups such as 0445120149/0213 even when both arrive in one shipment.

What should a distributor send for a fast WP12 quote?

Send 0445120127, 612630090012, WP12 rating and serial, truck model or VIN, old-unit photos, quantity, destination and packing preference. Mention 0445120389 only if it appears in the actual record. Complete data supports a faster commercial response without turning a possible cross-reference into an unverified fitment claim.
