OEX Starter Motor 12V 12 Tooth CW Denso Style DXS4030

The OEX Starter Motor DXS4030 is a new 12V starter motor with 12 teeth, clockwise rotation, and a Denso-style unit make. It carries a 1.7kW power rating, a 70mm flange diameter, and a 2-hole starter mount type, so the physical dimensions and mounting style can be checked before purchase.

This unit measures 192mm overall length, has a 47mm nose cone length, a 100mm mount centres A measurement, and a 32mm pinion diameter. The mount hole diameter is M10x1.5, the pinion at rest is 15mm, and the starter weighs 2.96kg.

It is listed as suitable for Denso applications and is not suitable for stop/start applications. The warranty shown is 3 years for passenger use and 1 year for commercial use, which is a useful checkpoint when comparing it with the vehicle’s original starter and service requirements.

Fitment guidance

• Fitment data is not fully verified here, so confirm the part number DXS4030 against the existing starter before ordering.
• The listed applications include Mercedes-Benz, Infiniti Q50, 5-T and 6-T ranges, but vehicle compatibility should still be checked against the specific engine and starter arrangement.
• Because this starter is Denso style and suits Denso units, matching the original unit make and mounting dimensions is important.
• Check the 12V rating, 12 tooth count, clockwise rotation, 2-hole mount, 100mm mount centres, and 70mm flange diameter against the removed starter.
• This starter is not suitable for stop/start applications, so vehicles with that system need a different confirmed application.

Application and Buying Notes

When replacing a starter motor, the part number, mounting pattern, tooth count, and rotation all need to line up with the original unit. For this OEX DXS4030, the key checks are 12V, 12 teeth, clockwise rotation, Denso style, and a 2-hole mount with 100mm mount centres.

The physical dimensions matter as much as the electrical rating. This starter measures 192mm overall, has a 47mm nose cone length, a 70mm flange diameter, and an M10x1.5 mount hole diameter, so a close visual match to the removed starter is a practical way to reduce ordering mistakes.

The 1.7kW power rating and 32mm pinion diameter give a clearer picture of the unit than voltage alone. If the original starter differs in tooth count, pinion position, or mount geometry, the replacement may not align correctly even if it appears similar at first glance.

This starter is listed as new and dry-clutch compatible, with a 3-year passenger and 1-year commercial warranty. It is not suitable for stop/start applications, so that system should be confirmed before fitting rather than assumed from the vehicle model alone.

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 DXS4030 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 12V 12Th CW Denso Style. Part number DXS4030 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number DXS4030, 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 5-T 2009, 5-T 2010, 5-T 2011, 5-T 2012, 6-T 2009, 6-T 2010. 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: Always confirm fitment using the part number DXS4030, the original starter’s mounting details, and the vehicle application details before ordering. If the removed unit does not match the listed 12V, 12 tooth, CW, Denso-style specifications, do not rely on appearance alone.
