OEX Starter Motor 24V 11 Tooth CW Delco 41MT Style DXS9146

The OEX Starter Motor DXS9146 is a 24V unit in 41MT style with 11 teeth, clockwise rotation, and a dry clutch setup. It suits Delco applications and is built as a new starter motor, not a remanufactured unit.

Key physical details include a 3 hole starter mount type, 126mm mount centres, a 92mm flange diameter, and a 400mm overall length. The pinion diameter is 56mm and the pinion at rest measures 48mm, so confirming the installation space and mating dimensions matters before ordering.

This starter motor is listed with a 7.7kW power rating and OEM number 23532A. It is supplied as an each item and carries OEX part number DXS9146, which is the most useful identifier to cross-check against your existing unit or application records.

Application and Buying Notes

Before ordering, compare the part number DXS9146, OEM number 23532A, and the physical dimensions against the starter already on the machine. The critical checks here are 24V voltage, 11 teeth, clockwise rotation, 3 hole mounting, and the 126mm mount centres, because a starter can look similar while still having a different mounting pattern or rotation.

The 41MT style and Delco unit make are important identifiers, but they should be matched with the exact application rather than assumed from appearance alone. The flange diameter is 92mm, the overall length is 400mm, and the mount hole diameter is 16mm, so any interference around the bellhousing or mounting face should be checked carefully.

This starter is listed as a new unit with a dry clutch configuration and 7.7kW power rating. If you are replacing an existing unit, confirm the pinion diameter of 56mm and pinion at rest of 48mm against the removed part, especially if the machine has had previous starter changes or non-original components fitted.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. That warranty detail is useful, but it does not replace the need to confirm the correct application, because fitment is still dependent on the exact machine, engine, and starter specification already in service.

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 DXS9146 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 24V 11Th CW Delco 41MT Style. Part number DXS9146 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number DXS9146, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm compatibility using the DXS9146 part number, OEM number 23532A, the Delco 41MT style reference, and the measured mounting and electrical details before purchase.
