OEX Starter Motor 12V 13TH CW Denso Style DXS537

The OEX DXS537 is a 12V starter motor with 13 teeth and clockwise rotation, listed as a Denso style unit. It is a new starter motor with a 2.5kW power rating, a 3 hole starter mount, and a dry clutch application.

Key dimensions include 127mm mount centres A, 90mm mount centres B, 90mm mount centres C, a 295mm overall length, and an 89mm flange diameter. The pinion measures 46mm in diameter and sits 48mm from rest, which makes these physical details important when checking replacement suitability.

This unit is described as a Perkins mount and the note provided is specific: for wet clutch applications use DRX72010 and swap the pinion. That makes the clutch type and mounting pattern important checks before ordering, especially where the original starter has been matched by dimensions rather than a vehicle model listing.

Application and Buying Notes

Before ordering, compare the part number DXS537 and the physical mounting details against the unit being replaced. The key checkpoints are the 12V electrical rating, 13 tooth pinion, clockwise rotation, 3 hole mount, and the stated mount centres of 127mm, 90mm and 90mm. A starter that is close but not identical in these areas may not install correctly or engage the flywheel as intended.

The listed notes matter. This starter is identified as a Perkins mount, and it is specified for dry clutch applications. If the vehicle or machine uses a wet clutch application, the provided guidance is to use DRX72010 and swap the pinion. That is a useful distinction because clutch type can change the starter arrangement even when the general style appears similar.

The Denso style reference and the 89mm flange diameter are practical comparison points when matching to an existing starter. The unit also has a 46mm pinion diameter, 48mm pinion at rest, 11mm mount hole diameter, and 295mm overall length. These measurements are worth checking on the old part or against the application data from the vehicle or machine.

This is a new starter motor and weighs 8.4kg, so handling, mounting alignment and cable routing should be checked during installation. The 2.5kW rating gives a useful indication of the unit’s intended output, but it should still be matched to the exact application rather than selected by output alone. If the original unit was a different mount style, rotation, or clutch type, stop and compare carefully before fitting.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, and from ISO certified factories. The warranty listed here is 3 years for passenger use and 1 year for commercial use. As with any starter motor replacement, the safest approach is to verify the part number, mount pattern, clutch type, and rotation before finalising the order.

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 DXS537 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 13Th CW Denso Style. Part number DXS537 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 DXS537, 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm compatibility by matching the part number DXS537, the 12V clockwise Denso style specification, the 13 tooth pinion, the 3 hole mount, and the stated mount dimensions before purchase. If the application is a wet clutch setup, the provided note directs you to DRX72010 instead.
