OEX Starter Motor 12V 12T CW Delco 40MT Style DXS9143

The OEX Starter Motor DXS9143 is a new 12V starter motor in Delco 40MT style, set up with 12 teeth and clockwise rotation. It is listed as a 3-hole starter mount type and suits Delco units, so the mounting style and unit make need to be checked alongside the part number before ordering.

Key dimensions include 126mm mount centres A, 126mm mount centres B and 126mm mount centres C, with a 92mm flange diameter and 16mm mount hole diameter. Overall length is 495mm, pinion at rest is 48mm, and pinion diameter is 46mm, which are the practical checks to compare against the original starter being replaced.

This starter is rated at 6.5kW and operates on 12 volts. It is listed as suitable for wet or dry clutch applications, weighs 30.26kg, and carries warranty cover of 3 years for passenger use and 1 year for commercial use.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, made in ISO certified factories, and backed by a nationwide warranty. Those points matter, but the correct vehicle match still comes down to matching the starter design, electrical rating, mount pattern and the listed part numbers.

Application and Buying Notes

Before fitting, compare the replacement starter against the original unit’s 12V electrical setup, 12 tooth pinion, clockwise rotation and 3-hole mount pattern. The listed 126mm mount centres, 92mm flange diameter and 495mm overall length are the main dimensional checks that help confirm whether DXS9143 is the correct physical match.

The part number DXS9143 and OEM number 50-100-1 are the most useful identifiers when you are cross-referencing a starter for Delco 40MT style applications. If the old starter is missing, damaged, or fitted with a non-standard replacement, checking the mount centres, pinion dimensions and unit make becomes even more important.

This unit is listed for wet or dry clutch use and weighs 30.26kg, which may be useful when comparing against an existing starter or when handling installation. For commercial applications, keep the 1 year warranty term in mind, while passenger use carries 3 years warranty cover.

When checking fitment on agricultural or industrial equipment, use the model listing as a guide only and still confirm the exact starter on the machine. Variations can occur within the same model range, so the safest approach is to match the part number, Delco application details and all listed dimensions before purchase.

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 DXS9143 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 DXS9143, 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.
