0445120474 Common Rail Injector Replacement for Weichai 1000400254

Every 0445120474 is a common rail injector and a solenoid injector in the heavy-duty Bosch family; the diesel common rail injector branch serves the Weichai WP10 to WD615 engines. The bosch common rail injector reference 0 445 120 474 is shown for interchange only. This 0445120474 diesel injector carries that Bosch reference on the body, and the 0445120474 fuel injector listing covers the whole range, so a 0445120474 injector order is matched on the etched code first, never on the model name alone. In workshop terms a heavy duty diesel injector, a solenoid valve injector and a truck injector of this family are one and the same assembly, so the bench reference is what we quote against.

Most buyers arrive with an etched code alone, and the weichai injector fitted to a haulage tractor and the one fitted to a tipper are the same assembly. A weichai wp10 injector, a weichai wp12 injector and a weichai wp13 injector all resolve to the weichai wd615 injector reference, and the wd615 injector number stamped on the old body is what we confirm against. The heavy duty truck buyer running a WD615 diesel, and anyone pricing a 6 cylinder diesel injector replacement, lands on the same unit. Full engine codes for this family are not published by the manufacturer, so the OE number is the match key, not the model name.

As a bosch injector built to the Bosch 0 445 120 474 specification, this 0445120474 fuel injector is a complete heavy-duty common rail unit. The injector specifications list the 0445120 CRIN2 branch, solenoid drive and the 12-month warranty. We bench-check injector flow rate and injector spray pattern on every batch; the Weichai OE number 1000400254 is shown as Reference. Injector identification starts with the WPCRIN2 mark on the body, which makes this a wpcr crin injector of the CRIN2 generation — the code an injector rebuilder reads before ordering. Model label, max injection pressure, emission, net weight, flow rate, solenoid winding resistance, per-unit opening pressure and the injector correction code are left as Not published because sources conflict or the manufacturer does not release them, so only the packaged shipping weight of 1.0 kg is stated. We state only what we can verify for this diesel injector.

For an injector cross reference, the Bosch 0 445 120 474 number is the reference and this bosch injector replacement is a Vidishi Auto compatible unit; as a bosch crin injector of the CRIN2 generation it carries the WPCRIN2 mark. Run a 0445120474 cross reference against the etched code, look for a 0445120474 equivalent, or key in a 1000400254 cross reference, and all three resolve to the same assembly. The weichai oe number 1000400254 is published so a buyer can match the correct replacement; we are an independent supplier, not a Weichai or Bosch distributor.

The diesel injector technology here is the heavy-duty solenoid type, and the internal diesel injector parts and diesel fuel injector parts — valve group, seat and needle — are matched as one calibrated set. Every unit is a precision diesel injector built to the Bosch 0 445 120 474 specification, so the same part works across the WP10 to WD615 range. Part numbers and service notes for the family sit under our maintenance guides.

Two measurements do most of the work: an injector return flow test, and a bench spray and seat-leak check. Bad injector symptoms and diesel injector symptoms rarely point to the injector alone — contamination past the filter, and a high-pressure fuel injection pump shedding debris, repeat the same damage, so fix the root cause as well as the unit. Some ECU generations store an injector coding value that must be written after replacement. If you are chasing a cylinder-balance code rather than a mechanical fault, start from the fault code library before pulling the unit.

Use an injector removal tool and an injector tester to confirm spray and seat, and torque to the injector torque spec with a fresh copper washer. A common rail injector replacement on a Weichai engine needs a clean high-pressure line and a new seal every time, and the injector installation is not finished until the correction value is written where the ECU requires it. Keep an injector service kit on the shelf for seals and washers. Part numbers and service notes for the family sit under our installation guides.

Every injector export shipping consignment ships in a 25 x 10 x 10 cm box at 1.0 kg gross with full export documents, and order status is visible under track order. A diesel injector export order is quoted per order because lead time moves with quantity and freight mode; see shipping information for freight modes and rules.

Before you buy, our buying guides cover how to read a heavy-duty injector code and match it to the correct engine. A fuel injection pump or an injector rebuild kit for the same platform is quoted on the same RFQ.
