OEX Starter Motor 12V 10 Tooth CW Denso Style DXS498

The OEX DXS498 is a new 12V starter motor with clockwise rotation, 10 teeth, and a 2.5kW power rating. It is listed as a Denso style unit and suits Denso applications, with a 3 hole starter mount and 89mm flange diameter for application matching.

Key dimensions include 127mm mount centres A, 90mm mount centres B and 90mm mount centres C, plus an overall length of 295mm and a pinion diameter of 40mm. The pinion at rest is 46mm, and the unit weighs 8.04kg, so it is important to compare the physical layout with the original starter before ordering.

This starter is supplied as a new rotating electrical component and is backed by a 3 year passenger / 1 year commercial warranty. It is described as a Denso style starter motor, but the correct application still needs to be confirmed by part number, mounting arrangement, tooth count and the vehicle or machine model listed for the original unit.

Application and Buying Notes

Before ordering, compare the part number DXS498, the 12V rating, clockwise rotation and the 10 tooth pinion with the starter you are replacing. The physical measurements are equally important here: 89mm flange diameter, 127mm mount centres A, 90mm mount centres B and C, 11mm mount holes, and 295mm overall length are all useful checks when confirming a direct replacement.

The note supplied for this unit should also be read carefully. If the drive end housing is rotated, the drive end housing mount bolts must go back into the same holes they came from, and one of the bolts is 5mm shorter than the other three. The note also states that this drive suits DRX72072 and will require the original pinion, so that detail should be checked before purchase if you are cross-referencing components.

This starter is listed as a Denso style unit and suits Denso applications, but that still needs to be matched to the original starter and the machine application. The fitment references include a broad range of agricultural, construction and industrial machines, yet the safest way to buy is by confirming the existing starter’s part number, mounting pattern, tooth count, rotation and overall dimensions against the replacement.

The 2.5kW power rating and 8.04kg weight may help confirm you have the correct style of heavy-duty starter, especially where the original unit is physically similar. If the vehicle or machine has been converted, modified or fitted with non-standard parts, take extra care and compare all available identifiers rather than relying on model name alone.

For workshop or fleet use, the 3 hole mount design and dry clutch specification are practical checks that can save time during installation. Matching these details to the removed starter is the best way to reduce the risk of ordering the wrong unit, particularly on equipment with several starter variants across the same model range.

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 DXS498 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.
