F00RJ04262 Injector Repair Kit for Bosch 0445120391 Weichai

Read this as one thing: an injector repair kit of matched parts rather than a single component. The common rail injector repair kit label is the trade name for exactly this bundle, and a diesel injector repair kit for the CRI2-16 family is what a workshop buys when the body and bore of the old unit are still sound. As an injector overhaul kit the F00RJ04262 is matched to the Bosch 0445120391 injector on the Weichai WP10, WP12, WP13, WD10 and WD615 engines, and the bosch F00RJ04262 reference resolves to the same kit number. The F00RJ04262 repair kit for the Bosch 0445120391 injector is therefore the F00RJ04262 injector kit that rebuilders order by number. Order it as the F00RJ04262 kit for 0445120391, and note that an F00RJ04262 overhaul kit order is matched on the kit number and the parent injector code together, never on the engine name alone.

Most buyers arrive with the number off the old injector rather than a model year, so the match key is the parent unit: a weichai wp10 truck and a weichai wp12 tractor unit that share the same Bosch 0445120391 injector take the same 0445120391 repair kit. The weichai wp13 haulage engine, the weichai wd10 bus chassis and the weichai wd615 fleet unit are covered the same way, because all five use that injector. Quote the kit number with the code etched on the old unit and we confirm the match. Specific engine codes beyond the WP10, WP12, WP13, WD10 and WD615 family labels are not published as a build list, so the OE number is the match key. Anyone pricing a weichai injector kit lands on the same F00RJ04262 overhaul kit for the 0445120391 injector.

This injector kit specification is stated at two levels. Confirmed at kit level: the kit number F00RJ04262, the injector overhaul kit parts it carries, the ISO 9001 mark shown on the kit packaging imagery, the 4 pcs minimum, the 30 × 20 × 3 cm box and the 1.000 kg gross shipping weight. Carried as Reference: the parent injector 0445120391, its Bosch number 0 445 120 391, the Weichai OE number 612630090055 and the CRI2-16 family. The injector kit parts that decide metering behaviour are the nozzle and the valve set, and both are supplied as one matched pair per kit. Where sources conflict or the manufacturer releases nothing, the row is left as Not published rather than filled with a plausible number — so bare kit net weight, the per-kit spray specification, the valve electrical data, material grades and a GTIN carried as our own number are all declared as unavailable above. As a kit these injector spare parts are supplied as one unit, and the specification a buyer should trust is the one printed on the label that arrives in the box.

Run an injector cross reference and the kit number, the printed form and the parent injector code all resolve to the same bundle. That is what a 0445120391 kit cross reference is for: it tells you whether a dealer listing, a rebuild note or a workshop invoice is pointing at the same 0445120391 overhaul kit that we supply. A F00RJ04262 cross reference and a F00RJ04262 equivalent search therefore land on one answer, and the component numbers inside the kit — DLLA147P2474 and F00RJ01727 — are listed so a rebuilder can confirm what is in the box before it is opened. Those numbers are published only as interchanges to identify the correct kit. We are an independent supplier of compatible replacement parts, not a Bosch distributor.

The injector repair kit quality question is really two questions. The first is whether the diesel injector repair kit parts are new and matched, and here they are: the nozzle and the valve set come from the same production route and are packed as one unit. The second is whether the injector overhaul kit quality survives freight, which is why each kit is trayed and boxed at 1.000 kg gross rather than bagged loose. Injector repair kit assembly matters as much as the parts, so the match marks are kept intact and the components are not mixed between kits. Judge the nozzle and valve kit on what arrives: a straight nozzle, a valve set with its seat face unmarked, and a label that carries the kit number.

Two measurements do most of the work: a fuel return flow test against the CRI2-16 figure, and a bench spray plus seat-leak check. None of the symptoms above proves the kit on its own — contamination past the filter, and a high-pressure fuel injection pump shedding debris, repeat the same damage, so fix the root cause as well. If the body, bore and seat are sound, an injector repair kit with a fresh nozzle and valve set restores the unit; if the body is cracked the unit is replaced instead. Some ECU generations store a correction value that must be written after a rebuild. If you are chasing a cylinder-balance code rather than a mechanical fault, start from the fault code library before pulling the injector.

The sequence above is the injector repair kit steps that decide whether a rebuild lasts. Use an injector removal tool rather than a lever on the body, and an injector tester rather than a guess, because a common rail injector repair is only finished when spray, seat leak and return flow are all inside specification. Keep the lines and the bore clean, fit new seals every time, and torque to the maker’s figure — an over-torqued clamp distorts the seat and the unit comes back. The injector installation is complete only when the correction value is written where the ECU requires it, and a rebuilt unit should always be bench-tested before it goes back on the engine.

The Bosch number on this page is shown only as the interchange for the parent injector, not as a brand claim, and the injector kit warranty cover is issued by an independent supplier of compatible replacement parts. Claims are handled against the batch that travelled with the kit, so keep the box label. Returns and remittance follow our returns policy.

We are an independent supplier and not an injector repair kit manufacturer; the Bosch and Weichai numbers on this page are reference interchanges only.

An injector kit export order is quoted per order because lead time moves with quantity and freight mode. Every consignment ships in the 30 × 20 × 3 cm box at 1.000 kg gross with full export documents, and order status is visible under track order. See shipping information for freight modes and rules.

Before you buy, our buying guides cover how to read a CRI2-16 code and match a parent injector to the right injector rebuild kit. A fuel injection pump for the same platform is quoted on the same RFQ, and the glossary explains the terms used across this page.
