OEX Starter Motor 24V 10T CW Denso Style DXS497

The OEX DXS497 is a new 24V starter motor in a Denso style layout, with clockwise rotation and 10 teeth on the pinion. It is listed with a 4.5kW power rating, 295mm overall length, and a 3-hole starter mount type, so the physical dimensions and mounting arrangement matter as much as the electrical rating when checking replacement suitability.

This unit is a dry clutch application starter motor and is supplied with mount centres A of 127mm, mount centres B of 90mm, and mount centres C of 90mm. Other key dimensions include an 89mm flange diameter, 10mm mount hole diameter, 40mm pinion diameter, and 48mm pinion at rest, which are the main checkpoints to compare before ordering.

OEX lists this product under part number DXS497 and describes it as a starter motor sourced from market leading original equipment manufacturers and aftermarket suppliers, with components sourced from ISO certified factories. The listed warranty is 3 years for passenger use and 1 year for commercial use, so it is important to match the application correctly before installation.

The notes supplied with the unit also mention wet clutch applications require DRX72010 wet clutch kit, and that if the drive end housing is rotated the mounting bolts must go back into the same holes, with one bolt 5mm shorter than the other three. It is also noted that the drive to suit DRX72072 will require the original pinion.

Application and Buying Notes

For a starter motor, the part number and the physical dimensions need to line up together. DXS497 is a 24V, 10-tooth, clockwise starter with a 4.5kW rating, so it should only be considered where the vehicle or machine requires those exact core details and the mounting pattern matches the 3-hole arrangement.

The listed measurements are practical buying checks, not background information. Mount centres A of 127mm, mount centres B of 90mm, mount centres C of 90mm, an 89mm flange diameter, and a 10mm mount hole diameter all need to be compared with the existing unit or the application specification. Even a small difference can stop the starter from mounting correctly.

The 48mm pinion at rest, 40mm pinion diameter, and 295mm overall length are also worth checking if space is tight or the old starter has a different nose and drive arrangement. The note about wet clutch use is important as well: this listing is for a dry clutch application, and wet clutch applications require DRX72010 wet clutch kit.

If you are replacing an existing starter, match the old unit as closely as possible before fitting. The note about drive end housing rotation and the shorter 5mm bolt is a useful workshop reminder, because reassembly errors can cause unnecessary damage or misalignment. The supplied information also says the drive to suit DRX72072 will require the original pinion, so that detail should be confirmed before any conversion or reuse decision.

Warranty information is listed as 3 years for passenger use and 1 year for commercial use, which is helpful when assessing the intended duty cycle. As with any starter motor, correct application identification is the safest path: confirm voltage, tooth count, rotation, mount pattern, and clutch type before you commit to installation.

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 DXS497 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.
