OEX Starter Motor 12V 9 Tooth CW Denso Style DXS405

The OEX DXS405 is a 12V starter motor in a Denso style layout, built with a 9 tooth pinion and clockwise rotation. It is listed as a new unit, with a 1.2kW power rating, 110mm mount centres, and a two hole starter mount, so it suits applications that match those physical and electrical details.

Key dimensions for checking before purchase include a 66mm flange diameter, M10 x 1.25 mount hole thread, 228mm overall length, 29mm pinion diameter, and 18mm pinion at rest. The unit weighs 3.4kg and is supplied as each starter motor.

OEX notes that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with production from ISO certified factories. The listed warranty is 3 years for passenger use and 1 year for commercial use, so it is worth confirming the intended application type before ordering.

Application and Buying Notes

Before ordering, compare the part number DXS405 and the physical mounting details against the removed unit. The important checkpoints here are 12V, clockwise rotation, 9 teeth, 110mm mount centres, M10 x 1.25 mount holes, and the 66mm flange diameter. If any of those differ, the starter may not suit the application.

The listed fitment references include Komatsu, MG MGA, and Toyota models, but the exact application still needs to be checked against the vehicle or machine configuration in use. Starter motors can vary by build date, engine setup, and mounting arrangement, so matching the model name alone is not enough on its own.

This is a new starter motor, not a remanufactured unit, and it is rated at 1.2kW. That rating, together with the 3.4kg weight and 228mm overall length, gives a useful comparison point when checking against the existing part. For commercial use, the warranty period differs from passenger use, so the purchase should be matched to the intended duty cycle.

If you are replacing a Denso style starter, confirm the pinion diameter of 29mm and pinion at rest measurement of 18mm as part of your cross-check. Those dimensions help narrow the match when the original unit is not clearly marked, especially on older machinery or vehicles where previous replacements may have been fitted.

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 DXS405 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 9Th CW Denso Style. Part number DXS405 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 DXS405, 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.

Available application references include KOMATSU FG10, KOMATSU FG10 1980, KOMATSU FG10-10, KOMATSU FG10-10 1980, MG MGA, MG MGA 1958. 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: Please confirm fitment by comparing part number DXS405, Denso style application details, and the full mounting and dimension measurements with the original starter before purchase. Do not rely on model name alone when checking compatibility.
