OEX Starter Motor 12V 10 Tooth CCW Denso Style DXS4042

The OEX DXS4042 is a new 12V starter motor with a 10-tooth pinion, counter-clockwise rotation, and Denso style fitment. It is listed with a 1.6kW power rating, a 2 hole starter mount, and a 65mm flange diameter, so it is the sort of unit that needs to be matched carefully to the vehicle and the starter pattern before purchase.

This starter motor is supplied under the OEX brand and is described as suitable for Denso units. Key physical details include an overall length of 225mm, a 32mm pinion diameter, a 71mm pinion at rest measurement, and an 11mm mount hole diameter. Those dimensions matter because starter interchange is often determined by the mounting pattern and pinion setup as much as by the electrical rating.

The unit is new, intended for dry clutch application, and is covered by a 3 year passenger / 1 year commercial warranty. For buyers comparing options, the part number DXS4042 is the most reliable identifier to use alongside the starter’s 12V, 10 tooth, CCW specification and Denso style configuration.

Application and Buying Notes

Before ordering, compare the part number DXS4042 with the existing starter and confirm the unit is a 12V, 10 tooth, CCW Denso style starter. Starter motors can look similar while differing in rotation, tooth count, mount type, flange size, and pinion dimensions, so those details should all line up before fitment is assumed.

The listed physical measurements are important for matching the unit to the vehicle: 225mm overall length, 65mm flange diameter, 32mm pinion diameter, 71mm pinion at rest, and 11mm mount hole diameter. The starter mount type is 2 hole, which is another point to check against the original unit or vehicle application.

This starter is specified as new and for dry clutch use. It also carries a 1.6kW power rating, which should be considered together with the application and the original starter details rather than treated as a universal upgrade. A correct match depends on the vehicle’s starter arrangement, not just on voltage alone.

If you are working from a removed starter, check the casting, label, pinion count, rotation direction, and mounting pattern. If you are working from vehicle details, use the fitment references as a guide only and still verify the DXS4042 part number and the Denso style specification against the original equipment before buying.

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 DXS4042 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.

For part number DXS4042, 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 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include SUBARU BRZ, SUBARU BRZ 2012, SUBARU BRZ 2013, SUBARU BRZ 2014, TOYOTA 86, TOYOTA 86 2012. 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 compatibility by matching the DXS4042 part number, 12V rating, 10 tooth pinion, CCW rotation, Denso style specification, and the listed mounting dimensions against the vehicle’s original starter.
