04289311 / VOE04289311 Fuel Injector: Fitment, Cross-References and Replacement Guide for Volvo EC240B and EC240C
If your Volvo excavator is hard to start, running rough or losing power, a worn fuel injector is one of the first things to check. This guide covers 04289311 (VOE04289311), a common-rail diesel injector used on Deutz-built engines in Volvo construction machinery. You'll find what the part number means, which part numbers cross-reference to it, how to spot a failing injector, and how to make sure you order the right one.
What Is the 04289311 / VOE04289311 Fuel Injector?
04289311 is a fuel injector part number used on Deutz-based diesel engines in Volvo equipment. The same part appears under several formats, so you may see it written as:
- 04289311 or 4289311 (Deutz / Volvo Penta format)
- VOE04289311 (Volvo Construction Equipment format, "VOE" prefix)
The injector sprays high-pressure diesel into the combustion chamber in a precise, finely atomized pattern. When it works properly, you get easy starts, smooth idle, strong power and good fuel economy. When it wears or leaks, all of those get worse.
Cross-Reference Numbers
Parts catalogs and suppliers list this injector under different numbers. These are commonly cross-referenced to 04289311:

Before ordering, compare the number printed on your old injector with this table. Part numbers are for identification only. Always confirm against your engine data plate.
Compatible Machines and Engines
This injector is commonly listed for:
- Volvo EC240B crawler excavator
- Volvo EC240C crawler excavator (as listed in our catalog; see the fitment check below)
- Volvo EC290B crawler excavator
- Deutz / Volvo D6D, D7D and D7E engines
- Some Volvo wheel loaders that use the same engine family, such as the L110E and L120E
Different production years and engine variants can use different injectors. The EC240B and EC240C are not identical machines, so don't rely on the model name alone.
How to Confirm Fitment Before You Order
- Read the number on the old injector and match it to the cross-reference table above.
- Check the engine data plate for the engine model and serial number.
- Check your machine's serial number and look it up in the Volvo parts catalog.
- Send us your machine model, serial number and a photo of the old injector if you're unsure. We'll help you confirm before you buy.
Signs Your Fuel Injector Needs Replacing
A failing injector rarely fails all at once. Watch for:
- Hard starting, especially when the engine is cold
- Rough idle or engine shaking
- Loss of power under load, such as digging or climbing
- Black or white smoke from the exhaust
- Higher fuel consumption than usual
- Engine fault codes related to injector circuits or cylinder balance
- Fuel smell or diesel dilution in the engine oil
Several of these symptoms can also come from filters, the fuel pump, air intake or sensors, so diagnose the system before you replace parts.
Replacement Tips
Replace as a set when possible. Injectors wear at a similar rate. Mixing one new injector with old, worn ones can leave cylinders unbalanced, which causes vibration and uneven power.
Find the root cause. Contaminated fuel, water in the fuel or a clogged filter will damage a new injector quickly. Replace the fuel filters and check the tank and lines when you change injectors.
Use new seals and copper washers. Reusing old sealing washers is a common cause of leaks and compression problems.
Keep everything clean. Clean around the injector before removal and cap open fuel lines. Even a few particles of dirt can damage a common-rail injector.
Follow the torque specification in the Volvo service manual for the clamp bolts and fuel line fittings.
Have a professional check the new injectors if your engine uses injector coding or calibration values.
