Nikko Starter Motor 24V 10TH CW NXS9711

The Nikko Starter Motor 24V 10th CW, part number NXS9711, is a new starter motor supplied as an each unit and intended for 24 volt applications. Key physical details include a 127mm mount centres A measurement, 82mm flange diameter, 289mm overall length, and a 39mm pinion diameter, so it is important to match the starter’s mounting and space requirements before ordering.

This unit is a clockwise rotation starter motor with 10 teeth, a 5.5kW power rating, and a 2 hole starter mount type. It is listed with a 11mm mount hole diameter, 15mm mount centres D, and a pinion at rest measurement of 47mm, all of which are useful when checking against the existing starter or the application details on the machine.

The starter is described as suitable for wet or dry clutch applications and is built to withstand harsh environments. It weighs 9.1kg and carries a one year warranty. The brand is Nikko, and the unit is identified as NXS9711 for reference when confirming the correct replacement part.

Application and Buying Notes

For a starter motor like this Nikko NXS9711, the most reliable checks are the part number, voltage, rotation, and mounting dimensions. This unit is 24V and clockwise rotation, with a 127mm mount centres A measurement, 82mm flange diameter, and 2 hole starter mount, so it should only be considered where those details line up with the existing starter or the machine application.

The 10 tooth pinion, 39mm pinion diameter, and 47mm pinion at rest measurement are also important. Even when the voltage matches, a starter can still be incorrect if the pinion and mounting arrangement do not suit the engine or housing. The 5.5kW rating is another useful reference point when comparing against the original unit.

If you are replacing an existing starter, compare the old unit carefully against the listed measurements before fitting. The overall length is 289mm, mount hole diameter is 11mm, and mount centres D is 15mm. Those dimensions matter where clearance is tight or where the mounting flange and bolt spacing need to match exactly.

The known applications provided are Komatsu machines, but compatibility should still be confirmed against the specific model and serial/application details on the machine. The same model family can use different starter variants, so the safest approach is to verify the part number NXS9711 and compare all critical measurements before purchase.

This starter is listed as suitable for wet or dry clutch applications and is described as built to withstand harsh environments. That makes it relevant for heavy-duty use, but it does not remove the need to confirm the 24V electrical system and the physical fitment checks first. The weight of 9.1kg may also be useful when comparing against the removed starter during inspection.

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 NXS9711 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty One Year, Mount Centres A 127mm, Mount Hole Diameter 11, Overall Length 289mm, Pinion Diameter 39mm, Rotation CW, Voltage 24, New / Reman. New.

Additional published details for cross-checking include Wet / Dry Clutch Wet or Dry, Product Group 2 STARTER MOTORS, Part No. NXS9711, Brand NIKKO, Description Nikko Starter Motor 24V 10Th CW, Flange Diameter 82mm, Mount Centres D 15mm, Number of Teeth 10, Pinion at Rest 47mm.

Nikko Starter Motor 24V 10Th CW. Part number NXS9711 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 NXS9711, 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 D31E-20, KOMATSU D31EX-21/PX-21, KOMATSU D31EX-21/PX-21 2008, KOMATSU D31EX/PX-22. 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.

Compatibility note: Confirm fitment using part number NXS9711, 24V system requirement, clockwise rotation, 10 tooth pinion, and the listed mounting dimensions before ordering.
