OEX Starter Motor 24V 11 Tooth CW Denso Style DXS523

The OEX DXS523 is a 24V starter motor with clockwise rotation, 11 teeth, and a Denso-style fitment profile. It is a new unit with a 4.5kW power rating, a 2-hole starter mount, and a 150mm mount centre measurement.

This starter motor is listed as wet clutch compatible and suitable for wet or dry clutch applications. Key dimensions include a 105mm flange diameter, 300mm overall length, a 40mm pinion diameter, and a 15mm pinion at rest, which are useful checkpoints when comparing against the existing unit.

OEX identifies this unit as part of its rotating electrical range, with product sourced from ISO certified factories and supported by a 3yr passenger / 1yr commercial warranty. The part number is DXS523, which is the best reference point for matching against the vehicle application and the removed starter.

This is a 24V replacement starter motor designed for applications that use a Denso-style unit with the same mounting and pinion configuration. As with any starter, the correct physical fit and electrical specification matter as much as the vehicle nameplate, especially on industrial equipment and forklifts.

• Fitment should still be confirmed against the original starter and the exact application details before ordering.

Application and Buying Notes

The most important buying check on this unit is matching the part number DXS523 and the physical specifications: 24V, 11 teeth, clockwise rotation, 150mm mount centres, and a 2-hole mount. Those details must align with the starter already fitted to the machine, because similar-looking starters can differ in rotation, tooth count, flange size, or mounting pattern.

The listed Denso-style design indicates the unit is intended for applications that use a Denso make starter, but style alone is not enough to confirm fitment. Compare the 105mm flange diameter, 300mm overall length, 40mm pinion diameter, and 15mm pinion at rest with the removed part where access allows. Those measurements can quickly rule out an incorrect match before installation begins.

This starter is rated at 4.5kW and weighs 8.3kg, so it is a substantial rotating electrical component rather than a small general-purpose starter. That makes accurate identification more important on industrial equipment such as Komatsu machines and Nissan Industrial forklifts, where the same model family can use different starter variants across production years.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. For commercial or industrial buyers, the practical step is to confirm the application, the mounting face, and the electrical setup before fitting, then keep the removed starter until the new unit is verified on the machine.

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 DXS523 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.

OEX Starter Motor 24V 11Th CW Denso Style. Part number DXS523 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 DXS523, 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 1986, KOMATSU D155A-2, KOMATSU D155A-2 1981, NISSAN INDUSTRIAL FORKLIFT, NISSAN INDUSTRIAL FORKLIFT 1985. 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 DXS523, the 24V specification, 11-tooth clockwise rotation, and the 150mm 2-hole mounting layout against the original starter and application details before purchase or installation.
