0-35000-4190 24V Alternator Nikko Type for Excavator Engine

0-35000-4190 24V Alternator Nikko Type

The 0-35000-4190 alternator is a Nikko type charging alternator used for construction equipment electrical charging systems. It is commonly searched together with the non-hyphen format 0350004190 and is listed in aftermarket references for Daewoo, Doosan and Komatsu equipment applications.

This page focuses on the 0-35000-4190 alternator signal, with model references such as Daewoo Doosan DH220-5, DH280, DH300 and DX300 included for fitment checking. Because alternator output, pulley type, regulator design and mounting layout may vary by machine version, the old alternator label and physical structure should be verified before ordering.

Product Information

Cross Reference and Number Format

The main part number for this product page is 0-35000-4190. The format 0350004190 is commonly used without hyphens and should be treated as the same searchable Nikko alternator number format.

Common cross references include Daewoo 2502-9007B and 2502-9009, Komatsu 6008256310, 6008616110 and 6008616111, Lester 12769, Cargo 115445 and J&N / Arrowhead 400-50032 references. Some catalogs also list Nikko 0-35000-4500, 0-35000-4501, 0-35000-4220 or 01-35-7000 as related alternator references.

These references should be used for identification support, not as automatic interchange confirmation. Alternators with related numbers may still have different amperage, regulator design, pulley position, plug type, terminal size or mounting bracket layout.

Daewoo Doosan Application Notes

The 0-35000-4190 alternator is frequently listed for Daewoo and Doosan construction equipment charging systems. Common model references include DH220-5, DH280, DH300 and DX300, with engine references such as DE08, DE12, DB58 and DB58T appearing in aftermarket catalogs.

Because Daewoo and Doosan excavators may use different alternator versions under similar model names, model number alone is not enough for final confirmation. The old alternator nameplate, mounting shape, plug, pulley and B+ terminal should be compared before ordering.

Komatsu Equipment Reference Notes

Several aftermarket references connect 0-35000-4190 and 0350004190 with Komatsu alternator numbers such as 6008256310 and 6008616110. These references are useful for buyers who search by Komatsu part number or by Nikko alternator number.

Komatsu applications should be treated as reference information unless the old unit confirms the same alternator label and structure. Before ordering for Komatsu equipment, verify voltage, output, pulley groove, mounting ear position and connector design.

Technical Identification Points

• Confirm the alternator label shows 0-35000-4190 or a matching cross reference.

• Check whether the charging system requires a 24V alternator.

• Verify the amperage rating because 50A and 60A references may appear in different catalogs.

• Compare pulley grooves, pulley offset and pulley diameter with the old unit.

• Check the B+ terminal size, plug type and regulator design.

• Compare mounting ear width, bolt hole size and bracket position before installation.

Common Failure Symptoms

• Battery warning light stays on during machine operation.

• Battery cannot stay charged after engine running.

• Low charging voltage is measured at the battery terminals.

• Electrical components become weak or unstable during operation.

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

• Burning smell, overheating or visible damage appears around the alternator.

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

Troubleshooting Before Replacement

Before replacing the 0-35000-4190 alternator, inspect the complete charging circuit. Battery failure, poor grounding, damaged wiring, belt slip or a loose pulley 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.
