Couldn't load pickup availability
Complete set of 6 genuine new Bosch 0432133788 diesel fuel injectors (mechanical nozzle-and-holder assemblies, Bosch DHK family) — a full engine set for the 6-cylinder Perkins 1106C-E60TA 6.0 litre engine and the Caterpillar 3056E engine fitted to 924G, 928G and 930G wheel loaders, M316C, M318C and M322C wheeled excavators, CS/CP-series compactors, AP-series asphalt pavers and 550B, 560B, 574B forest machines. The equivalent OE references are Perkins 2645F027 and Caterpillar 216-9786 (Cat Reman 20R-0478). Replacing all 6 injectors as a matched set restores balanced fuel delivery across all cylinders — the recommended practice for high-hour diesel engines.
Each injector is a complete mechanical nozzle-and-holder assembly with a factory-set opening pressure of 250-264 bar, supplied brand-new in its original individual Bosch box, and fed by a Bosch VP30 electronically controlled distributor injection pump. Always confirm compatibility by Bosch number, OE number, engine code, engine serial number, or the identification number stamped on the original injector before ordering.

Why Replace Injectors as a Complete Set
On a high-hour Perkins 1106C or Cat 3056E, all 6 injectors accumulate the same running hours and wear at a similar rate. Replacing only one leaves 5 worn units in service, producing uneven cylinder balance, smoke and vibration, and usually leads to repeat downtime shortly after. A matched set of 6 new injectors restores identical opening pressure and spray pattern on every cylinder in a single intervention — one workshop visit, one set of washers, one calibration baseline. On machines that earn by the hour, the avoided second teardown is usually worth more than the parts.

Related Diesel Fuel System Parts
The Bosch VP30 distributor pump below is the injection pump these injectors are commonly paired with on the Perkins 1106C / Caterpillar 3056E engine family. It is not necessarily the only pump code fitted to these engines: Perkins and Caterpillar used different injection pump variants depending on engine build, machine model, power rating, emissions specification and production date, so a different Bosch pump code may be the correct one for your machine. Always identify the pump by the number on the unit currently fitted to your engine before ordering, rather than by machine model.

FAQ
How many injectors are included? Six brand-new genuine Bosch 0432133788 injectors, each in its original individual Bosch box — a complete set for one 6-cylinder engine.
Are these genuine Bosch fuel injectors? Yes. All six are brand-new genuine Bosch OEM diesel fuel injectors supplied in original Bosch packaging, made in Brazil.
Which engines use Bosch 0432133788? The Perkins 1106C-E60TA 6.0 litre engine and the Caterpillar 3056E engine. Both are 6-cylinder units, so this set covers one complete engine.
Which Caterpillar machines does this set fit? Machines powered by the Cat 3056E engine, including the 924G, 924GZ, 928G and 930G wheel loaders, the IT28G toolcarrier, the M316C, M318C, M318C MH and M322C wheeled excavators, the CP-563E, CP-573E, CP-663E, CS-563E, CS-573E, CS-583E, CS-663E and CS-683E compactors, the AP-600, AP-655C, BB-760 and BG-2255C pavers, and the 550B, 560B, 564 and 574B forest machines.
Can I buy a single injector instead? Yes — the same injector is available per piece here. The set price is lower than buying 6 single pieces.
What are the Perkins and Caterpillar OE reference numbers? Perkins 2645F027, Caterpillar 216-9786, and Caterpillar Reman 20R-0478.
What is the opening pressure? Each injector has a factory-set opening pressure of 250 to 264 bar.
Are these common rail injectors? No. These are mechanical nozzle-and-holder assemblies (Bosch DHK family), not common rail injectors. Fuel metering and timing are controlled by the Bosch VP30 distributor injection pump, not by the injectors.
Do these injectors need coding or programming after fitting? No. They are purely mechanical injectors with no electrical connection, so no ECU coding or IMA calibration is required.
Are nozzle sealing washers included? No. Sealing washers are NOT included and must be sourced separately. Fitting new sealing washers is recommended when installing a full set.
Why replace all 6 injectors at once? A matched set restores identical opening pressure and spray pattern on all cylinders, avoiding the uneven running and repeat downtime that follow single-injector replacement on a worn engine.
Which injection pump works with these injectors? On this engine family the injectors are fed by a Bosch VP30 distributor injection pump — order number 0470006009, OES number 0470006002 (the same pump), Bosch trade number 0986444517, Perkins 2644P502. Other pump codes may be fitted depending on engine build and machine configuration, so check the number stamped on your own pump before ordering.
Is professional installation recommended? Yes. Professional installation is recommended to ensure correct fitment and proper torque settings.
Diagnostic Information
Common Symptoms of Fuel Injector Failure
Hard starting, long cranking, unstable idle, engine misfiring, loss of power, rough running, excessive smoke, knocking, or increased fuel consumption may indicate worn or faulty injectors. On the Perkins 1106C / Cat 3056E, a dripping nozzle or an opening pressure that has drifted below the 250 bar specification typically shows up first as black smoke under load and a knocking cylinder. These symptoms can also be caused by the VP30 injection pump, fuel filtration, air in the fuel system, low compression, or other diesel engine management issues, so a full diagnosis is recommended before replacement.
Installation and System Check
Before replacing diesel fuel injectors, inspect the fuel filter, check for water or contamination in the fuel, and verify injection pump operation. Injectors should be tested for opening pressure, spray pattern and leak-off against the 250-264 bar specification. Installing new injectors into a contaminated fuel system may result in repeat failure. When fitting a complete set, replace the fuel filter and use new nozzle sealing washers on every cylinder.
