17204355 Alternator for Volvo D6D Engine

17204355 Alternator for Volvo D6D Engine

The 17204355 alternator is used in Volvo construction equipment charging systems and is commonly searched together with the Volvo reference format VOE17204355. This page focuses on the 17204355 alternator signal for Volvo D6D engine applications and Volvo excavator model references.

Common model references include Volvo EC210B, EC210BLC, EC240B and EC290B, with additional EC140B, EC160C and EC180C references used for fitment checking. Because alternator output, connector type, pulley design and mounting layout may vary by machine version, final fitment should be verified by the old alternator label and physical structure before ordering.

Cross Reference and Number Format

The main part number for this page is 17204355. VOE17204355 and VOE 17204355 are Volvo-style number formats used in catalog searches and buyer inquiries.

Bosch-related references such as 0124655008 and 0124655499 may appear in alternator catalog data connected with this Volvo reference. These numbers should be used as identification support, not as automatic interchange confirmation.

Alternators with related numbers may still have different amperage, connector shape, pulley groove count, regulator design, terminal layout or mounting bracket position. The old alternator label and actual unit photos are the safest basis for confirmation.

Volvo D6D Engine Application Notes

This 17204355 alternator is commonly used for Volvo D6D engine charging system service. It is suitable for buyers who need to replace a failed charging alternator after low charging voltage, battery warning light, bearing noise or unstable electrical output.

Engine model is useful for initial identification, but it should not be used alone. Volvo machines with similar engine families may use different alternator specifications, so the old alternator number, connector, pulley and mounting points should be compared before quotation.

Volvo Excavator Model References

Common Volvo excavator model references include EC210B, EC210BLC, EC240B and EC290B. Some catalog and supplier references also list EC140B, EC140C, EC160C, EC180C, EC210C, EC220D, EC240C and EC290C applications.

These model names should be treated as fitment references rather than guaranteed applications. Before ordering, check the machine serial number, original alternator label, voltage output, connector type, pulley groove and mounting layout.

Technical Identification Points

• Confirm the old alternator label shows 17204355, VOE17204355 or a matching reference.

• Check whether the machine uses a 24V charging system.

• Verify the amperage rating on the old alternator label before replacement.

• Compare the connector type, plug pin count and wiring layout.

• Check the pulley groove count, pulley offset and pulley diameter.

• Compare mounting ears, bolt hole position and bracket clearance before installation.

Common Failure Symptoms

• Battery warning light stays on during machine operation.

• Battery voltage remains low after the engine is running.

• The battery cannot stay charged after normal work cycles.

• Electrical components become weak, unstable or intermittent.

• Abnormal noise appears from the alternator bearing or pulley area.

• Overheating, burning smell or visible damage appears around the alternator.

• Repeated belt wear occurs because of pulley misalignment or bearing resistance.

Troubleshooting Before Replacement

Before replacing the 17204355 alternator, inspect the complete charging circuit. Battery failure, poor grounding, belt slip, damaged wiring or charging relay problems can create symptoms similar to alternator failure.

• Check battery condition and battery terminal connection.

• Measure charging voltage with the engine running.

• Inspect alternator belt tension, pulley alignment and belt wear.

• Check the B+ cable, ground cable, plug connector and charging relay circuit.

• Inspect whether oil, dust or water has entered the alternator body.

• Compare the old alternator part number and physical layout with the replacement alternator.

Installation and Maintenance Notes

• Disconnect the battery before removing the alternator.

• Clean the mounting bracket and check that the alternator sits correctly.

• Install the belt with the correct tension and pulley alignment.

• Tighten electrical terminals securely and protect them from short circuit risk.

• After installation, check charging voltage and battery warning light status.

• Recheck belt tension after initial operation if the belt was replaced.

• Avoid operating the machine with loose battery cables or unstable charging voltage.

FAQ

What is 17204355?

17204355 is a Volvo alternator part number used for construction equipment charging system applications.

Is VOE17204355 the same as 17204355?

Yes. VOE17204355 and VOE 17204355 are Volvo-style reference formats for the 17204355 alternator number.

Is this product an alternator or a starter motor?

This product should be described as an alternator or charging generator. It should not be described as a starter motor.

Which Volvo engine is the main reference for this page?

The main engine reference for this page is Volvo D6D. Final fitment should still be confirmed by the old alternator label and machine configuration.

Which Volvo excavator models are common references?

Common references include Volvo EC210B, EC210BLC, EC240B and EC290B, with additional EC140B, EC160C and EC180C references used for fitment checking.

What should be checked before ordering?

Check the old alternator label, voltage, amperage, connector, plug pin count, pulley grooves, pulley offset, B+ terminal and mounting hole position before ordering.

Why does a replacement alternator fail quickly?

Early failure can be caused by weak batteries, poor grounding, belt slip, loose cables, incorrect pulley alignment, water or oil contamination, or unstable charging circuit wiring.
