OEX Starter Motor 24V 12 Tooth CW Delco 50MT Style DXS9159

This OEX starter motor is a new 24V unit with 12 teeth, clockwise rotation, and a 50MT style configuration for Delco applications. It carries part number DXS9159 and is listed with an 8.9kW power rating, so the key checks before purchase are voltage, rotation, tooth count, and the Delco unit type.

The mounting arrangement is a 3 hole starter mount with 126mm mount centres A, B, and C, plus a 102mm flange diameter and 17mm mount hole diameter. The pinion diameter is 46mm, which is another useful check when matching against the original starter in the machine.

This is a starter motor sold each, not a remanufactured unit, and the warranty is listed as 3 years for passenger use and 1 year for commercial use. For buyers replacing a starter in equipment that uses a Delco 50MT style setup, the part number and the listed dimensions should be compared carefully before ordering.

Application and Buying Notes

Before ordering, compare the existing starter’s part number, voltage, tooth count, and rotation against this unit: DXS9159, 24V, 12 tooth, and clockwise. Those points are the first and most reliable checks, especially where the machine uses a Delco 50MT style starter.

The mounting pattern also matters. This unit is listed with a 3 hole starter mount, 126mm mount centres A, B, and C, a 102mm flange diameter, and 17mm mount hole diameter. If any of those measurements differ from the old starter, the unit may not physically match even if the application looks similar.

The 8.9kW power rating and 46mm pinion diameter are useful comparison points when confirming the replacement starter. They help separate similar-looking units that may not be interchangeable, particularly in heavy equipment or industrial applications where starter dimensions and drive details need to line up exactly.

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 DXS9159 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 12Th CW Delco 50MT Style. Part number DXS9159 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 DXS9159, 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.

Available application references include CATERPILLAR 583K, CATERPILLAR 583K 1982, CATERPILLAR 594H, CATERPILLAR 594H 1974. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number DXS9159, the Delco 50MT style designation, 24V system voltage, 12 tooth clockwise rotation, and the listed mounting and pinion dimensions against the original unit before purchase.
