OEX Starter Motor 12V 9TH CW Denso Style DXS4020

This OEX starter motor is a new 12V unit with 9 teeth, clockwise rotation and a Denso-style application. The listed part number is DXS4020, with a 1kW power rating, 2-hole starter mount type and a dry clutch design. It is intended as a direct replacement only where the vehicle application and mounting details match exactly.

Key physical dimensions to check before ordering are the 120mm mount centres, 80mm flange diameter, 53mm nose cone length and 211mm overall length. The pinion diameter is 30mm, the pinion at rest is 20mm, and the mount hole diameter is 11mm. Those measurements are important because starter motors may look similar but still differ in fitment.

The unit suits Denso applications and is sold as a new starter motor, not remanufactured. OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with manufacturing from ISO certified factories and support from a nationwide warranty. For this part, the warranty listed is 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

When replacing a starter motor, matching the part number and physical layout is just as important as matching voltage. This unit is 12V, clockwise rotation and 9 tooth, so it should only be considered where the existing starter matches those basics, along with the Denso-style application and 2-hole mounting arrangement.

The dimensions provided here are the most useful checks to confirm at the vehicle side: 120mm mount centres, 80mm flange diameter, 53mm nose cone length and 211mm overall length. If any of those measurements differ from the original starter, the unit may not seat correctly or may not align with the pinion and bellhousing as expected.

This starter is listed as new and dry clutch, with a 1kW power rating and a 3kg weight. Those details can help when comparing to the removed part, especially where the original unit is damaged, missing a label or fitted with non-standard accessories. The safest approach is to compare the old starter, the mounting points and the part number DXS4020 before purchase.

OEX lists a passenger warranty of 3 years and a commercial warranty of 1 year for this part. That warranty does not replace the need to confirm application details, particularly on equipment where several similar starters may share the same general look but differ in tooth count, rotation or nose cone length.

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 DXS4020 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 9Th CW Denso Style. Part number DXS4020 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 DXS4020, 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.
