OEX Starter Motor 12V 11T CW Delco 42MT Style DXS9147

The OEX Starter Motor DXS9147 is a new 12V starter motor in 42MT style, set up for Delco applications with clockwise rotation. It carries 11 teeth, a 7.0kW power rating, and a 3 hole starter mount, so the main identification points are clear before you compare it against the vehicle or machine being serviced.

Key physical dimensions include 126mm mount centres A, B and C, a 92mm flange diameter, 16mm mount hole diameter, and an overall length of 490mm. The pinion diameter is 56mm and the pinion at rest measures 48mm, which are useful checks when matching the starter to the original unit.

This unit is supplied as new and weighs 26.74kg, so it is a substantial rotating electrical component rather than a small light-duty starter. The listed unit make is Delco, and the series is 42MT, which are the two most important reference points alongside the part number DXS9147 when confirming suitability.

• Because the fitment list is broad, the original starter should be checked against the Delco 42MT style, 12V rating, 11 teeth, clockwise rotation, 3 hole mount and the recorded dimensions before ordering.

Application and Buying Notes

When comparing this starter to the one already fitted, the most useful checks are the part number DXS9147, the Delco 42MT style, and the physical measurements of 126mm mount centres with a 92mm flange diameter. Those details help confirm the housing and bolt pattern are in the right range before the unit is fitted.

Voltage and rotation matter just as much as size. This unit is 12V with clockwise rotation, so it should only be considered where those electrical and directional requirements match the existing application. The 11-tooth pinion and 56mm pinion diameter are also important if the original starter uses the same engagement setup.

The 7.0kW power rating indicates a heavy-duty starter arrangement, and the 26.74kg weight reflects that. For larger diesel engines, industrial equipment or road transport applications, it is worth checking the exact mounting style, overall length of 490mm and pinion at rest measurement of 48mm against the removed unit rather than relying on appearance alone.

Although the fitment list covers many makes and models, a starter motor should always be verified against the actual vehicle or machine identification, not just the brand. Matching the listed specification set to the existing starter is the safest way to avoid downtime and unnecessary returns.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. That is useful context, but it does not replace fitment checking. In starter motor work, the correct part number, voltage, rotation, tooth count and mounting dimensions remain the key decision points.

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 DXS9147 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 11Th CW Delco 42MT Style. Part number DXS9147 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 DXS9147, 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.

Compatibility note: Please confirm compatibility by matching part number DXS9147, Delco 42MT style, 12V, clockwise rotation, 11 teeth and the listed mounting dimensions against the existing starter and application details before purchase.
