Product Details
0445120465 Common Rail Injector by the Numbers
Verified identity and fitment data for the complete heavy-duty diesel common rail injector, supplied for the Weichai WP13 range.
Every 0445120465 is a common rail injector and a solenoid injector in the heavy-duty Bosch family; the diesel common rail injector branch serves Weichai WP13 engines. The bosch common rail injector reference 0 445 120 465 is shown for interchange only. This 0445120465 diesel injector carries that Bosch reference on the body, so a bosch 0445120465 injector search resolves to the same Weichai fitment, and the 0445120465 fuel injector listing covers the whole WP13 range. A 0445120465 injector order is matched on the etched code first, never on the model name alone.
Engine Compatibility for 0445120465
This complete injector runs the Bosch common rail system on Weichai WP13 heavy-duty diesel engines. Match the engine nameplate and the number on the old injector before ordering.

Heavy duty diesel injectorFull heavy-duty category
Weichai applicationsTrucks, machinery, fleets
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 wp13 injector and a weichai truck injector resolve to the same 612630090025 injector reference. Quote the 612630090025 number stamped on the old body and we confirm the match. The heavy duty truck injector buyer running a WP13 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.
Fitment verification
- VIN or chassis number — we decode the build record to confirm the engine family.
- Engine code plate — the plate on the block must read a Weichai WP13 unit on Bosch common rail injection, not another family.
- Photo of the old unit — the number stamped on the injector body, so we match the code and not just the engine.
About the 0445120465 Injector
What the complete heavy-duty unit is, and how it sits in the Weichai WP13 fuel system.
What is a common rail injector?
This is the solenoid unit that meters and atomises fuel from the rail into the combustion bowl. The 0445120465 is a complete unit in the heavy-duty Bosch 0445120 branch: the whole injector, not just a spray tip.
How does a common rail injector work?
The rail holds fuel at pressure and the ECU fires the solenoid, so the needle lifts for a controlled window. On a WP13 engine the valve opens, the spray forms, and the ECU trims each cylinder individually. A worn 0445120465 diesel injector shows up as a weak cone or a seeping seat long before it stops running.
Complete unit versus parts
The injector is the complete assembly; the diesel injector parts and fuel injector parts such as the valve and seat sit inside it. The common rail injection system meters fuel through a diesel fuel injector on each cylinder, and a bosch diesel injector reference (0 445 120 465) is a heavy-duty unit — the whole assembly, not bare common rail injector parts. A common rail diesel injector of this generation leaves the factory as one sealed unit, and we supply it that way.

As a bosch injector built to the Bosch 0 445 120 465 specification, this 0445120465 fuel injector is a complete heavy-duty common rail unit. The common rail injector specifications list the 0445120 CRIN 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 612630090025 is shown as Reference. Model label, pressure, emission, net weight, flow rate, coil 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 1.5 kg is stated. We state only what we can verify for this diesel injector. Injector identification: the code 0445120465 and the Weichai number 612630090025 are stamped on the body, and that is the same identification an injector rebuilder reads before ordering.
Cross-Reference & Interchanges
Need a 0445120465 cross reference or a 0445120465 equivalent? The interchange numbers below are the ones buyers match against. All are reference interchanges only.
For an injector cross reference, the Bosch 0 445 120 465 number is the reference and this 0445120465 bosch replacement is a Vidishi Auto compatible unit. Run a 0445120465 cross reference against the etched code, or look for a 0445120465 equivalent, and both resolve to the same assembly: the weichai oe number 612630090025, also written 6126 3009 0025, on the weichai wp13 612630090025 platform. Those numbers are published so a buyer can match the correct replacement; we are an independent supplier, not a Weichai or Bosch distributor.
Key Features
Why the 0445120465 heavy-duty unit is built for Weichai WP13 service.
Heavy-duty CRIN injector
Part of the Bosch 0445120 heavy-duty branch, built for precise metering under full load on Weichai WP13 diesels.
Complete unit, not a tip
The whole solenoid injector is supplied — a direct replacement for the Bosch common-rail unit on the WP13 engine.
Built for duty cycle
Specified for long-haul duty and stop-start site work across WP13 haulage, tipper and off-highway fleets.
New and warranted
Supplied new with a 12-month warranty against manufacturing defects.
Compatible brand
Vidishi Auto compatible replacement — reference interchanges only, not a genuine Bosch part.
Precise metering
Solenoid valve design for stable idle and clean combustion after a bench test.
The diesel injector technology here is heavy-duty solenoid common rail injector technology, a high pressure diesel injector built for Weichai heavy-duty diesels. This bosch crin injector uses a solenoid valve injector for precise metering and is a precision diesel injector supplied new. Each unit is a heavy-duty Bosch reference built to the Bosch 0 445 120 465 specification, so the same part works across the WP13 range.
Failure Symptoms
Common rail injector symptoms to watch for on a Weichai WP13 engine, and the checks that separate a tired unit from a healthy one.
| Symptom | What it usually means |
|---|---|
| injector leakage | An internal leak loses rail pressure between injections and can coke the tip. |
| injector misfire | A weak or seeping unit drops combustion quality on one cylinder at idle and under load. |
| injector failure | Long service wears the valve seat; the unit loses calibration before it stops. |
| black smoke diesel engine | Poor atomisation from a worn spray raises soot and exhaust opacity under load. |
| hard start injector | Low cranking compression on one cylinder or a leaking seat delays start-up. |
| injector fault code | An ECU cylinder-balance or circuit code points to one unit for a bench test. |
| weak spray pattern | A worn cone shows an uneven, narrow spray rather than a clean fan on the tester. |
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.
How to replace common rail injector on a Weichai WP13
A bench-side walk-through of injector installation for the 0445120465, from a single injector replacement to a full bench test.
Confirm the code
Match the etched 0445120465 / 0 445 120 465 and the WP13 engine plate before removal.
Relieve pressure
Depressurise the common rail and isolate the battery before opening the fuel lines.
Remove and inspect
Unbolt the old unit, fit a fresh copper seal, and check the bore and seat for scoring or debris.
Fit to injector torque
Seat the new 0445120465 to the clamp torque spec with a clean seal; never reuse a washer or over-torque the clamp.
Purge and code
Bleed air from the fuel line and write the injector coding value if the ECU generation requires it.
Bench-test
Run the bench test on spray pattern, seat leak and return flow before refitting.
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 WP13 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.

Buyer Feedback
Field notes from workshops and fleets running the 0445120465 on Weichai WP13 engines.
Matched the old 0 445 120 465 on our WP13 haulage fleet; smooth idle and clean combustion after a bench test. Compatible part, not an original Bosch unit — exactly what we needed for the price.
Two units replaced tired injectors on site tippers; rail pressure restored and smoke dropped. Every unit passed an injector quality check and a diesel injector test before dispatch.
