Product Details
F00RJ03569 Injector Repair Kit by the Numbers
Verified identity and contents for this CRIN2 injector overhaul kit, supplied for the Weichai WP7 EU4 injector.
A repair kit is a different purchase from a complete injector. The F00RJ03569 set arrives with the F00RJ02035 control valve and the DLLA152P2422 nozzle already matched, so the job is a bench rebuild plus a coding step on the refitted injector rather than a whole-unit swap. Because the Weichai WP7 EU4 injector carries its own calibration, the same injector body is matched by the number printed on it, and a workshop rebuilding a faulty unit will order the exact kit number rather than a machine-year guess. On the WP7 platform a single injector can be rebuilt without disturbing the rest of the fuel system, which is what makes per-cylinder service practical on a high-mileage machine that cannot stand still for long.
Engine Compatibility for F00RJ03569
This injector overhaul kit serves the Weichai applications below. Match the kit number and the injector body number before ordering. A Weichai WP7 injector such as the 0445120373 unit is the injector this kit rebuilds.
| Kit / component | Reference | Description |
|---|---|---|
| F00RJ03569 | F00RJ03569 | Current Bosch overhaul-kit number for this application |
| F00RJ02035 | F00RJ03569 | Bosch F00RJ02035 control valve supplied in the kit |
| DLLA152P2422 | F00RJ03569 | Bosch DLLA152P2422 nozzle supplied in the kit |
| 0445120373 | F00RJ03569 | Weichai OE number of the injector this kit serves |
| 610800080588 | F00RJ03569 | Weichai OE number quoted for the same injector |
Engine and machine applications
| Make | Engine | Description | Fitment | Kit |
|---|---|---|---|---|
| Weichai | WP7 EU4 | heavy-duty CRIN2 common rail diesel engine in trucks and machinery | by engine | F00RJ03569 |
| Weichai | WP7 | inline six-cylinder common rail diesel platform (EU4) | by engine | F00RJ03569 |
| Weichai | WP7 injector service | per-injector rebuild on the WP7 head using this kit | by machine | F00RJ03569 |
| Weichai | WP7 replacement | rebuild of a failed injector rather than a whole-unit swap | by engine | F00RJ03569 |

Kit number match
Match the number on the kit label to F00RJ03569, or to the spaced Bosch form F 00R J03 569. Where the engine is a Weichai WP7, the injector it carries is the 0445120373 CRIN2 unit, and a Weichai WP7 injector rebuild uses this F00RJ03569 kit. A Weichai WP7 EU4 injector and a Weichai WP7 CRIN2 injector are the same injector family this kit serves, so one kit number spans the range.
For a Weichai injector repair kit such as F00RJ03569, the fitment is the Weichai WP7 EU4 CRIN2 injector only; the kit is not quoted for other engine families. A WP7 injector rebuild with this kit is matched by the body number, so send a photo of the old injector if you are unsure. A Weichai WP7 EU4 injector and a plain Weichai WP7 injector share the same CRIN2 hardware on the machines listed above, with no change to the kit itself. The injector this kit serves is a diesel injector for the whole WP7 family, so a single kit number spans the range.
The approach works the same whichever of those labels your own paperwork uses — the number on the kit and the injector body number are what we confirm, and a Weichai WP7 CRIN2 injector is the same injector by whichever machine it is quoted.
Fitment verification
- Kit part number — match the etched code on the kit label to F00RJ03569, or to the spaced form F 00R J03 569.
- Injector body number — the injector this kit serves must read 0445120373 (Weichai WP7 EU4 CRIN2).
- Photo of the old injector — a picture of the body marking and the engine code plate, so we match the revision and not just the model.
What an injector repair kit does
On a diesel with the Bosch common rail system the injector is the final actuator; a repair kit is what lets a workshop rebuild it instead of swapping the whole unit.
An injector repair kit rebuilds a common rail injector on the bench: the F00RJ03569 kit carries the F00RJ02035 control valve and the DLLA152P2422 nozzle, with the seals and washers the job needs. A Bosch injector repair kit of this family arrives as a matched set, not as a sealed complete injector, so the rebuild is a bench job on the valve and nozzle rather than a swap. That distinction matters when buying: a diesel injector repair kit is the route when the injector body is sound but the internals are worn, while a complete injector is the route when the body itself is contaminated.

The difference between a complete injector and the parts inside it is the point of an injector overhaul kit. A CRIN2 injector repair kit such as F00RJ03569 is graded at the injector family level, and the two fields that settle the match are the kit number on the label and the injector body number the kit serves. Both routes exist on this platform and the choice is usually about bench time and warranty exposure rather than about the part itself. A common rail injector repair kit and a compatible complete unit are described by different words in a parts catalogue, but the application they target is the same Weichai WP7 EU4 CRIN2 injector.
Matched set
Valve, nozzle, seals and washers supplied together as one kit.
Bench rebuild
Rebuild the injector rather than swap the whole unit.
Coding
The refitted injector carries a calibration the ECU reads, written in after fitting.
Because the refitted injector is coded, the same physical injector behaves differently depending on the data it carries. The F00RJ03569 kit returns the injector to service with a fresh valve and nozzle, and an injector that has not been told which one it is driving will run with default maps. When the choice is an injector repair or replace decision, the bench test settles it: a sound body is worth rebuilding with a kit, a contaminated one is not.
A repair kit on this platform is a robust way to keep a high-mileage machine running, and much of the failure comes from contamination at the nozzle or from a worn valve rather than from the solenoid itself. The DLLA152P2422 nozzle in this kit is the spray end the rebuild restores, and the F00RJ02035 valve is the actuator it renews. Judging an injector on whether the engine still runs tells you almost nothing; judging it on the fault codes and the live data tells you nearly everything, and that is what points back at a rebuild with this kit.
Diesel injector repair kit, overhaul kit or complete injector — three trade names
Which of those names a supplier writes on the offer depends on who is buying. A workshop ordering a rebuild quotes the kit number on the old injector. A fleet parts desk sourcing for an operator quotes the engine code instead. A distributor stocking the CRIN2 range quotes the family. The article behind all three labels is the same F00RJ03569 kit, and so is the test that settles the match: the number on the kit label and the injector body number it serves.
That is the reason we ask for the kit number rather than the machine model. Whether your own paperwork calls this a CRIN2 injector repair kit, a Bosch injector repair kit for the Weichai WP7 or simply a diesel injector repair kit for the CRIN2 range, the code on the part is what we confirm, and the code we ship against is the one you state.

Parameters marked Not published are not asserted anywhere on this page, and no figure is substituted for them further down. A common rail injector repair kit such as F00RJ03569 is graded at the kit level, not by a generic catalogue line. Where your workshop needs a specific reading, request the test report for the injector you rebuild with this kit. The calibration code etched on the injector you refit is what the ECU is written with after fitting.
The Bosch injector repair kit number on this page is F00RJ03569, and the kit it names rebuilds the Weichai WP7 EU4 CRIN2 injector 0445120373. An injector rebuild kit of this family is a matched set of valve, nozzle, seals and washers, so the rebuild follows the injector’s own geometry rather than a universal pattern. A common rail injector rebuild kit is the practical choice when the injector body is sound but the internals are worn, because it returns the unit to service without a whole-unit swap. Buyers comparing a diesel injector repair kit across suppliers should expect the same set of published fields from each, and the same honesty about the fields nobody publishes.
Injector rebuild kit, overhaul kit and complete injector — what the terms cover
All three descriptions point at related but different purchases on this platform, and the term narrows the spec. A counter serving workshops writes the kit up with the shorter wording and quotes the number on the old unit; a parts desk buying for a fleet writes it up with the engine. What arrives in the box is a matched overhaul set either way: the F00RJ03569 common rail injector repair kit built to the CRIN2 reference design.
What does change the specification is the calibration code of the injector being rebuilt, and the code is not written in the trade name. Since the refitted injector carries a calibration the ECU reads, an incorrect or unwritten code will leave the rebuilt unit running on default maps whatever the label on the carton says. That is a different failure mode from grading a part by its description alone, and it is why we record both the kit number and the coding step on the offer we send.
Failure Symptoms
Common injector failure signs to watch for on the Weichai WP7 diesel before an injector is rebuilt with this kit. Most common rail injector problems show first as a rough idle or a stored fault code rather than a hard no-start.
- Rough idle or a persistent cylinder misfire
- Hard starting or extended cranking
- Stored fault codes naming an injector circuit
- White or black smoke from the exhaust
- Elevated fuel consumption
- Knock or uneven combustion under load
- Loss of power on a specific cylinder
- Contamination found at the nozzle tip
Injector failure symptoms overlap with pump, sensor and wiring problems, and CRIN2 injector problems on this family are the same set of codes seen through a different lens, so a scan tool reading plus a live-data check is the normal way to isolate a single injector. Summaries of the stored codes are grouped on our diesel fault codes page, and the list above can be read alongside live data rather than trusting a guess. Diesel injector fault symptoms on this family usually present as a cylinder-specific misfire that points back at the injector, which is exactly the part this F00RJ03569 kit rebuilds.
Most CRIN2 injector problems on this engine start with fuel quality or contamination rather than with the solenoid. The classic giveaway is a misfire that follows a tank of poor fuel, then clears after the system is flushed. Letting the machine run on until the early signs turn into a hard fault rarely saves money, because an injector that has been killed by contamination will usually have taken the nozzle with it. A rebuild with this kit should follow a confirmed diagnosis: read the fault codes, check the fuel and the harness, and only then commit to the injector the ECU is flagging. Renewing the fuel filter alongside the rebuild is worth considering on a high-mileage machine, where the supply is usually at the same stage of wear.
Rebuild and refit notes
Fitting a rebuilt injector is a cleanliness-critical job with a second, electronic step that decides whether the engine runs properly. A correct common rail injector installation starts with clean fuel and ends with the calibration written into the ECU.
Confirm the code
Record the kit number and the calibration on the injector you are removing before stripping anything.
Relieve pressure
Depressurise the common rail and work on a clean, dry bench to protect the nozzle and the connector.
Rebuild with the kit
Fit the F00RJ02035 control valve and the DLLA152P2422 nozzle from the F00RJ03569 kit, with fresh seals and copper washers.
Inspect the seat
Check the cylinder-head injector seat and the seal ring for carbon, corrosion or damage before refitting.
Fit and torque
Seat the injector squarely and torque the fixing to the figure your workshop data gives.
Write the code
Transfer or rewrite the calibration with a suitable scan tool before the engine is run in earnest.
An injector replacement on this engine is normally done in the vehicle rather than on the bench, because the injector is a complete article once rebuilt; nothing inside it is being opened beyond the kit parts. The cleanliness discipline still applies: the nozzle seat must be clean and the seal ring sound, or the rebuilt injector will leak or misfire. Where the job is being done as part of a fuel-system service, a fresh seal ring and a new seal are worth ordering at the same time. Our injector rebuild guide walks the full bench sequence for this kit.
The injector repair or replace decision is settled by the bench test: a sound body is worth rebuilding with this kit, a contaminated one is not. Injector coding is the step most often missed, and a CRIN2 injector installation done without it will run rough even though the mechanical work was correct. Until the calibration is written in, the ECU will run on default maps. Help reading the values before and after is available through our fuel system maintenance notes, and the full sequence is set out in our injector fitting guide and installation notes.
Reference and interchange numbers
Need an injector cross reference or a F00RJ03569 equivalent? The numbers below are the ones buyers match against. All are reference interchanges only.
A F00RJ03569 cross reference lists the Bosch exchange number F 00R J03 569 alongside the component numbers F00RJ02035 and DLLA152P2422, so a buyer can match the kit by either route. Injector kit interchange is shown below: the F00RJ02035 valve and the DLLA152P2422 nozzle kit are the two core components, and the 0445120373 injector is the unit the kit rebuilds. Cross-checking against the Weichai number is safe only when the old injector or the engine parts book carries that number. The F00RJ02035 valve and the DLLA152P2422 nozzle kit identify the kit’s contents, so a search for a Bosch F00RJ03569 listing and a search for the component numbers lead to the same kit. A plain injector interchange by internal number walks the same path from the other end, starting from the Bosch kit number rather than the engine one. These numbers identify one kit; they are not a statement that this kit is an original-equipment part.
The kit label also carries a production marking alongside the kit number, reproduced here only so a buyer can recognise what they are reading. The F00RJ02035 valve and the DLLA152P2422 nozzle kit are supplied as a matched set, and the table above deliberately stops at kit level. If your old injector is stamped with a number that does not appear here, send us a photograph of the body before ordering and we will check it against the CRIN2 range. Where a listing gives an injector cross reference figure, check that it names the engine as well as the number, because an interchange written without the platform is not a match.
Two suppliers can quote the same kit under different wording — one listing a repair kit, another an overhaul set for the WP7 range, a third a short maker number. None of those descriptions identifies the kit on its own. The two fields that do are the full kit number and the engine the injector is built for, which is why we record both on the offer we send.
Build quality and inspection
Every kit is built and checked before it leaves us.
Each F00RJ03569 kit is built to the CRIN2 architecture used by the Weichai WP7 EU4 injector, so the F00RJ02035 control valve and the DLLA152P2422 nozzle match the injector they serve. The seals, the copper washers and the O-rings are set as part of the kit rather than added afterwards.

The internal numbers inside the injector are revision-dependent: confirm by the kit number and the injector body number before ordering, because this engine can carry more than one revision across its production years. That is also why we take a photograph of the kit label rather than relying on a catalogue entry. A diesel injector test on the rebuilt unit confirms the spray and the leak-off before it leaves us, and an injector inspection against the body number is part of that record. Where a workshop wants figures rather than a pass or fail, the injector can be run on a bench tester and the diesel injector test report supplied with the order.
Alongside complete injectors we hold related fuel-system parts for this family, so a rebuilder can service an injector instead of replacing it whole. Where a workshop is ordering an injector inspection rather than a complete injector, the internal numbers are confirmed against the body you send us.
Wholesale & bulk supply
Vidishi Auto is an export supplier of diesel fuel-system parts, serving workshops, rebuilders and distributors who service Bosch CRIN2 injectors in volume. Our injector repair kit wholesale programme supplies single kits through container quantities.
4 pcs, with tiered terms as quantity rises.
Matched batches for workshop stock and engine sets.
Each kit is carton-sealed for freight.
As one of the injector suppliers serving export workshops we consolidate mixed fuel system orders into a single shipment. Where a workshop buys a few kits at a time to cover a failed injector, the Bosch injector price is quoted on tiered terms rather than on a single unit, and the effective diesel injector wholesale cost per piece falls as the batch grows. Buyers who place a standing order usually want the same kit from batch to batch, which is what our stock holding is arranged to give. Send your required quantity and destination port for a quotation. Tiered terms and lead times are on our wholesale pricing page.
Packaging, weight and shipping
Export packing and freight for single boxes through container volumes, quoted per order. The injector cost is quoted per quantity, with the single-unit box packed for export.
10 × 8 × 5 cm.
1.0 kg gross per pack.
4 pcs.
Kit boxed, wrap, carton sealed.
The 10 × 8 × 5 cm pack is sized for a single boxed kit, so a small batch for the WP7 engine range ships as a compact carton rather than a stack of oversize boxes. The packaged shipping weight is 1.0 kg gross per pack, which covers the valve, the nozzle, the seals and the sealed bag. Freight options and delivery estimates are set out on our shipping information page; returns and cancellations are covered under returns.
The injector cost for this reference moves with quantity and freight, so the figure that applies to your order is the one quoted and confirmed before dispatch. Whether you are comparing a quotation from a local distributor or a common rail injector cost from another exporter, ask for it to include freight and the warranty terms so the comparison is like for like. The injector repair kit cost is quoted per quantity, and where a kit is listed as an injector repair kit for sale at a headline figure, check whether the price is per piece and whether freight is included before you commit.
For a single kit the courier option is usually the fastest route; for a workshop quantity, a consolidated carton or a pallet brings the freight cost per piece down. Where a shipment is going to a resale address, ask for the commercial invoice and packing list to be issued with the dispatch documents so customs clearance is not held up at the destination.
