OEX Starter Motor 12V 9 Tooth CW Delco Style DXS503

The OEX Starter Motor DXS503 is a 12V, clockwise rotation unit built in a Delco style with a 9 tooth pinion and 1.2kW power rating. It is supplied new, not remanufactured, and uses a 2 hole starter mount with 114mm mount centres and an 82mm flange diameter.

This unit is listed with a 52mm nose cone length, 215mm overall length, 25mm pinion diameter, and 19mm pinion at rest. The mount hole size is M12x1.75 / 10, and the starter weighs 3.4kg, which are useful checks when comparing the replacement against the original unit.

OEX notes that 9 and 10 tooth units are interchangeable for this application, but the part should still be matched carefully by the part number, rotation, mounting pattern, and physical dimensions. The listed suit make is Delco, so matching the original starter style is an important part of the buying decision.

Application and Buying Notes

Before ordering, check the part number DXS503 against the starter being removed, then compare the 12V rating, clockwise rotation, 9 tooth pinion, and Delco style mounting details. The physical measurements are just as important as the electrical details, especially the 114mm mount centres, 82mm flange diameter, 52mm nose cone length, and 215mm overall length.

The note that 9 and 10 tooth units are interchangeable can help where the original unit is damaged or hard to read, but it does not replace a full fitment check. The starter mount type is 2 hole, the mount hole diameter is M12x1.75 / 10, and the pinion at rest measures 19mm, so these are sensible points to compare before fitting.

If you are matching a replacement for a Daewoo or Holden application, confirm the exact vehicle details, engine setup, and the starter already fitted to the vehicle. The fitment list covers several models and model years, but the safest approach is to verify the original unit’s tooth count, rotation, mounting pattern, and overall dimensions before purchase.

This is a new starter motor with a 1.2kW power rating and a dry clutch arrangement. Those details matter when you are comparing like-for-like replacements, because the wrong physical layout or rotation will stop the part from lining up correctly even if the vehicle badge appears on the fitment list.

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 DXS503 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 DXS503, 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.
