Nikko Starter Motor 24V 12T CW NXS9719

The Nikko starter motor listed here is a new 24V unit with 12 teeth and clockwise rotation, identified by part number NXS9719. It is a starter motor for the Nikko unit make, supplied as each, and rated at 11kW for heavy-duty rotating electrical applications.

Key physical details include a 3-hole starter mount, 127mm mount centres A, B and C, a 92mm flange diameter, and a 16mm mount hole diameter. The nose cone length is 105.5mm, the overall length is 411mm, and the pinion diameter and pinion at rest measurement are both 46mm.

This starter motor is listed as suitable for wet or dry clutch use and carries a one-year warranty. The only stated performance claim is that it is built to withstand harsh environments, so it is best treated as a heavy-duty replacement part that should be matched carefully by part number, mounting pattern, and electrical specification.

Application and Buying Notes

Before ordering, compare the part number NXS9719 against the existing starter and check that the machine uses a 24V electrical system. A 12-tooth pinion, clockwise rotation, and 3-hole mount are important identifiers on this unit and should line up with the installed starter arrangement.

Mounting dimensions matter on this model. The listed mount centres are 127mm for A, B and C, with a 92mm flange diameter and 16mm mount hole diameter. Those measurements help confirm that the starter will sit correctly against the bellhousing or mounting face without forcing the fit.

The overall length is 411mm and the nose cone length is 105.5mm, so physical clearance should be checked where access is tight. The pinion diameter and pinion at rest are both 46mm, which is another useful point of comparison when checking the replacement against the removed unit.

This starter is described as suitable for wet or dry clutch use and has a power rating of 11kW. Those details do not replace fitment confirmation, but they do help identify the unit as a heavy-duty starter intended for demanding equipment applications.

If you are matching by application rather than by the old starter alone, use the listed fitment references as confirmation points and still verify the installed part number, tooth count, rotation, and mounting measurements. That is the safest way to avoid ordering the wrong starter for a machine with similar-looking components.

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 NXS9719 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.

Nikko Starter Motor 24V 12Th CW. Part number NXS9719 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 NXS9719, 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.

Compatibility note: Confirm compatibility by checking part number NXS9719, 24V electrical system, 12-tooth clockwise rotation, and the 3-hole mounting dimensions before purchase. Application references are provided as fitment guidance only and should be matched against the machine and the removed starter.
