OEX Starter Motor 24V 12 Tooth CW Delco 42MT Style DXS9151

The OEX Starter Motor DXS9151 is a new 24V unit in 42MT style, set up with 12 teeth and clockwise rotation. It suits Delco applications and is specified with a 7.8kW power rating, making the key identifiers easy to check before ordering.

Mounting and size details are important on this starter. It has a 3 hole starter mount type, 126mm mount centres A, B and C, a 92mm flange diameter, 16mm mount hole diameter, and an overall length of 490mm. Those measurements should be matched against the existing unit or application details before purchase.

The pinion figures are also listed clearly: 46mm pinion diameter and 48mm pinion at rest. The starter is noted as suitable for wet or dry clutch applications, and the unit weight is 26.4kg, which is useful when comparing like-for-like replacements or confirming handling and installation expectations.

Application and Buying Notes

Before ordering, compare the part number DXS9151 and the application details against the starter currently fitted to the machine. This unit is a 24V, 12 tooth, clockwise rotation starter in 42MT style, so voltage, tooth count, rotation, and series all need to line up with the replacement requirement.

The mounting dimensions are just as important as the electrical rating. Confirm the 3 hole mount pattern, 126mm mount centres, 92mm flange diameter, 16mm mount hole diameter, and 490mm overall length. If any of these measurements differ from the removed starter, fitment should be checked again before purchase.

The listed fitment examples include Atlas Copco, Case, and Caterpillar applications, but those examples should be used as guidance only. Machine variations, build dates, and previous component changes can affect what is fitted, so the safest check is to match the starter against the existing unit and the machine’s actual application details.

The pinion dimensions and resting position are useful when checking engagement and clearance. With a 46mm pinion diameter and 48mm pinion at rest, this starter is intended to be assessed as a complete assembly, not by electrical specification alone.

This starter is noted as suitable for wet or dry clutch use, which is helpful when comparing it with a removed unit from the same machine family. Even so, the correct replacement still depends on the full combination of voltage, rotation, teeth, mounting pattern, and overall length.

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 DXS9151 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty 3yr Passenger 1yr Commercial, Mount Centres A 126mm, Mount Centres C 126mm, Number of Teeth 12, Pinion at Rest 48mm, Power Rating 7.8kW, Series 42MT, Voltage 24.

OEX Starter Motor 24V 12Th CW Delco 42MT Style. Part number DXS9151 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 DXS9151, 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.

Compatibility note: Confirm fitment by matching part number DXS9151, 24V specification, 12 tooth clockwise rotation, 42MT style, and all mounting dimensions against the existing starter and machine application before ordering.
