Nikko Starter Motor 24V 13T CW NXS9710

The Nikko starter motor NXS9710 is a 24V, clockwise rotation unit with 13 teeth and a 5.5kW power rating. It is listed as a new starter motor for Nikko applications, with a 3 hole mount type, 136mm mount centres A, 119mm mount centres C, and a 100mm flange diameter.

This unit measures 370mm overall length, has a 47mm pinion diameter, a 53mm pinion at rest, and a 13mm mount hole diameter. It weighs 10.3kg and is supplied with a one year warranty.

The listed note for this starter motor states: if the relay senses voltage on the alternator lead, White with Green Stripe, there will be no engine restart. That detail is worth checking carefully before purchase, especially where the starting system has been previously altered or diagnosed for intermittent restart issues.

Application and Buying Notes

Before ordering, match the part number NXS9710 and confirm the physical dimensions against the original starter on the machine. The key checks here are 24V system voltage, clockwise rotation, 13 teeth, 370mm overall length, 100mm flange diameter, and the 3 hole mount layout with 136mm, 119mm and 119mm mount centre measurements.

The starter is specified as a Nikko unit, so it is most suitable where the existing application calls for Nikko equipment and the listed dimensions align. A starter can share a similar appearance with another unit but still differ in pinion position, mount centres, or rotation, so those measurements matter just as much as the part number.

The note about the relay sensing voltage on the alternator lead, White with Green Stripe, is important for troubleshooting. If the machine has a no-restart condition, that electrical detail may need to be checked as part of the diagnosis rather than assuming the starter alone is at fault.

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 NXS9710 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 13Th CW. Part number NXS9710 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 NXS9710, 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 KOMATSU COMPRESSOR, KOMATSU COMPRESSOR 1999, KOMATSU D31, KOMATSU D31-17. 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: Confirm compatibility by matching the part number NXS9710, the 24V CW specification, the 13 tooth pinion, and the recorded mount and dimension details against the existing starter and machine application before purchase.
