OEX Starter Motor 12V 10 Tooth CW Denso Style DXS578

The OEX DXS578 is a new 12V starter motor built in a Denso style configuration, with clockwise rotation and a 10 tooth pinion. Key physical checks include a 127mm mount centres dimension, 89mm flange diameter, 11.5mm mount hole diameter, and 250mm overall length.

It is rated at 2kW and suits a wet or dry clutch application. The pinion details are listed as 40mm diameter with 47mm pinion at rest, so it is worth comparing these measurements with the unit you are replacing before ordering.

OEX positions this starter motor as a quality replacement for the Australian automotive aftermarket. The part number is DXS578, and the unit is supplied new, not remanufactured, with a 3 year passenger vehicle warranty or 1 year commercial warranty.

Because starter motor fitment can depend on the exact unit style as well as mounting and drive dimensions, the safest approach is to compare the listed specifications with the original starter on the vehicle or machinery before purchase.

Application and Buying Notes

Before ordering, compare the part number DXS578, the 12V electrical rating, the 10 tooth pinion, and the clockwise rotation against the original starter motor being replaced. These details are the first checkpoints for confirming that the unit is the correct style for the application.

The mounting dimensions matter just as much as the electrical rating. This unit has 127mm mount centres, an 89mm flange diameter, 11.5mm mount holes, and a 2 hole starter mount, so a close physical match is important where space and bolt pattern are restricted.

The pinion measurements are also relevant. With a 40mm pinion diameter and 47mm pinion at rest, this starter should only be chosen where those dimensions align with the original unit or the application specification.

This starter motor is listed as Denso style and is suitable for wet or dry clutch applications. That does not remove the need to verify the exact application, especially where the machine may have had previous repairs, upgrades, or alternative starting components fitted.

Warranty cover is 3 years for passenger vehicle use and 1 year for commercial use on the new unit. If the starter is being selected for a commercial or equipment application, it is sensible to confirm the usage category before purchase.

At 2kW and 4.86kg, this is a substantial replacement starter motor rather than a generic universal unit. Matching the mounting, rotation, tooth count, and physical dimensions is the practical way to reduce the chance of an incorrect order.

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 DXS578 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.
