OEX Starter Motor 12V 12 Tooth CW Delco 42MT Style DXS9149

The OEX starter motor DXS9149 is a 12V unit in 42MT style, with 12 teeth, clockwise rotation and a Delco suitability note. It is listed as a new starter motor for rotating electrical applications, and the mounting pattern is shown as 3 hole with 126mm mount centres at A, B and C.

Key physical checks for this starter include a 490mm overall length, 92mm flange diameter, 16mm mount hole diameter and a 46mm pinion diameter. The pinion at rest is listed at 48mm, and the unit weighs 26.48kg, which is useful when comparing against the existing starter on the machine.

The stated power rating is 7.8kW, and the starter is marked as suitable for wet or dry clutch applications. OEX lists this product with a 3 year passenger and 1 year commercial warranty, which gives a clear use-case reference when matching the starter to the vehicle or equipment it is intended for.

Fitment guidance

• No verified vehicle fitment is supplied here, so the starter should be matched by part number, starter style and physical dimensions before purchase.
• Check that the existing unit is a Delco 42MT style starter with 12V operation, clockwise rotation and a 12-tooth pinion.
• Confirm the mounting pattern against the 3-hole design, 126mm mount centres, 92mm flange diameter and 16mm mount hole diameter.
• Compare the overall length of 490mm, pinion diameter of 46mm and pinion at rest of 48mm against the removed starter.
• Use the vehicle or equipment application only as supporting information after the dimensional and part number checks are complete.

Application and Buying Notes

For this OEX starter motor, the most important buying checks are the part number DXS9149, the Delco suitability note and the 42MT style designation. Those details should be matched against the old unit or the parts catalogue for the machine, because starter motors can look similar while differing in mount pattern, rotation or pinion specification.

The electrical and mechanical specifications are specific: 12V, 7.8kW, clockwise rotation and 12 teeth. If any one of those does not match the original starter, fitment may be incorrect even if the housing appears close. The 3-hole mount with 126mm centres is especially important on heavier equipment and industrial applications.

The physical size also matters. At 490mm overall length and 26.48kg, this is a substantial starter, so confirm there is enough clearance around the bellhousing and adjacent components. The 46mm pinion diameter, 48mm pinion at rest and 92mm flange diameter are useful reference points when checking against the removed unit.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That is helpful for understanding the intended support level, but it does not replace the need to verify the application first. As with any starter, the safest approach is to compare the old part, the mounting face and the electrical requirements before fitting.

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 DXS9149 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 Delco 42MT Style. Part number DXS9149 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 DXS9149, 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.
