Nikko Starter Motor 24V 15T CW NXS619

The Nikko NXS619 starter motor is a new 24V unit with 15 teeth and clockwise rotation, supplied as a 3 hole starter motor for heavy industrial use. It is listed with an 11kW power rating, 430mm overall length, 105mm flange diameter and 20kg weight, so it is a substantial rotating electrical component rather than a light-duty replacement.

This starter is noted as suitable for Mitsubishi heavy industrial S12R and S16R engine applications, with the supplied fitment data also referencing Mitsubishi Industrial S12A2-Y1TAA1, S12R and S16R families. As with any industrial starter, the correct match depends on the engine application, mounting layout and drive specification, not just the brand name.

Key identifying details include part number NXS619 and OEM number 0-23000-7691. The unit is described as new, with wet or dry clutch compatibility noted, and it carries a one year warranty. Those details make it important to compare the existing starter before ordering, especially where the engine is in heavy equipment or a specialised industrial installation.

Application and Buying Notes

Before ordering, compare the part number NXS619 and OEM number 0-23000-7691 against the unit being replaced. For industrial starters, the part number, mounting pattern and rotation are just as important as the visible size, and this unit is specified as 24V, 15 tooth, clockwise and 3 hole mount with 140mm mount centres A and B, plus 127mm mount centres C.

Check the physical dimensions on your existing starter where possible. The listed flange diameter is 105mm, the overall length is 430mm, the mount hole diameter is 13mm, and the pinion diameter is 70mm with 50mm pinion at rest. Those measurements help confirm that the replacement will physically suit the application before installation begins.

This starter is described as suitable for Mitsubishi heavy industrial S12R and S16R engine applications, and the fitment preview also includes Mitsubishi Industrial S12A2-Y1TAA1 groups. That still leaves room for application differences, so the safest approach is to confirm the engine model, mounting arrangement, electrical setup and clutch type on the machine, not only the engine family name.

The unit is new and carries a one year warranty, which may be useful when planning maintenance on heavy industrial equipment. The listed wet or dry clutch compatibility is also a useful checkpoint, but it should still be matched to the application you are working on rather than assumed to cover every version of a given engine family.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number NXS619 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Additional published details for cross-checking include Starter Mount Type 3 Hole, OEM Number 0-23000-7691, Product Group 2 STARTER MOTORS, Part No. NXS619, Brand NIKKO, Description Nikko Starter Motor 24V 15Th CW, Flange Diameter 105mm, Mount Centres B 140mm, Mount Hole Diameter 13.

Nikko Starter Motor 24V 15Th CW. Part number NXS619 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number NXS619, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MITSUBISHI INDUSTRIAL S12A2-Y1TAA1, MITSUBISHI INDUSTRIAL S12A2-Y1TAA1 1977, MITSUBISHI INDUSTRIAL S12R, MITSUBISHI INDUSTRIAL S12R 1999. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment by checking part number NXS619, OEM number 0-23000-7691, the 24V 15T CW specification, and the mounting and dimensional details against the existing starter and engine application before ordering.
