OEX Starter Motor 24V 11 Tooth CW Denso Style DXS550

The OEX DXS550 is a new 24V starter motor with 11 teeth, clockwise rotation and a 4.5kW power rating. It is listed as a Denso style unit and suits Denso applications, so matching the part number and mounting dimensions is the safest way to confirm it is the correct replacement for your machine.

Key physical measurements include 135mm mount centres A, 110mm mount centres B, 110mm mount centres C, a 105mm flange diameter and an overall length of 271mm. The starter uses a 3 hole mount, 13mm mounting hole diameter, 40mm pinion diameter and 41mm pinion at rest, which are all useful checkpoints when comparing to the unit being removed.

This starter motor is built for rotating electrical applications and is supplied as a new unit, not remanufactured. OEX lists the warranty as 3 years for passenger applications and 1 year for commercial use, which is worth noting when deciding how the part will be used and what support applies.

Application and Buying Notes

Before ordering, check the part number DXS550 against the unit you are replacing and compare the mounting pattern carefully. The listed dimensions matter: 135mm mount centres A, 110mm mount centres B and C, a 105mm flange diameter and a 271mm overall length all need to align with the existing starter setup.

Rotation and pinion details are just as important on a 24V starter. This unit is clockwise rotation with 11 teeth, a 40mm pinion diameter and 41mm pinion at rest, so it should only be considered where those values match the required application and the removed starter.

The starter is listed as a Denso style unit and suits Denso applications. That means the best buying practice is to verify the machine model, engine or equipment application, and the physical starter dimensions together rather than relying on one detail alone.

Weight is listed at 8.66kg, and the unit is a 3 hole mount with 13mm mounting holes. Those details can help confirm whether the replacement matches the original housing and mounting hardware arrangement before installation starts.

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 DXS550 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 Denso Style. Part number DXS550 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 DXS550, 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.
