OEX Starter Motor 12V 9 Tooth CW Denso Style DXS494

The OEX DXS494 starter motor is a new 12V unit with clockwise rotation and a 9 tooth pinion, suited to Denso applications. It carries a 2.5kW power rating, a 3 hole starter mount type, and an SAE1 indexed mounting bracket for wet clutch applications.

Key dimensions are listed as 297mm overall length, 89mm flange diameter, 127mm mount centres A, 90mm mount centres B and C, 11mm mount hole diameter, 35mm pinion diameter, and 48mm pinion at rest. These measurements matter when checking physical clearance and mounting alignment before ordering.

This starter motor is supplied under the OEX brand and is backed by a 3 year passenger / 1 year commercial warranty. It is described as suitable for wet or dry clutch use, but the fit must still be checked against the vehicle application and the existing starter configuration.

Application and Buying Notes

Before ordering, compare the part number DXS494, the Denso style application, and the mounting details on your existing starter. The listed 3 hole mount, 127mm and 90mm mount centres, 89mm flange diameter, and 11mm mount hole diameter need to match the vehicle setup, as starter fitment is determined by both the electrical specification and the physical mounting pattern.

The 12V rating and 2.5kW output are important checks if you are replacing a starter that must match the original electrical system. The 9 tooth pinion, 35mm pinion diameter, and 48mm pinion at rest should also be compared carefully, because pinion and engagement dimensions affect whether the starter will suit the ring gear arrangement on the vehicle.

If you are cross-referencing an existing starter, use the part number and dimensions together rather than relying on appearance alone. The overall length of 297mm and the 7.98kg weight provide useful confirmation when checking against the removed unit, especially on older vehicles where replacement parts may have been changed previously.

The warranty is 3 years for passenger use and 1 year for commercial use. Warranty coverage does not replace the need to verify fitment before purchase, so the safest approach is to confirm the vehicle application, mounting pattern, and tooth count against the details supplied here.

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 DXS494 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 DXS494 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 DXS494, 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 INTERNATIONAL HARVESTER CM-SERIES, INTERNATIONAL HARVESTER CM-SERIES 1972, INTERNATIONAL HARVESTER CM-SERIES 1973, INTERNATIONAL HARVESTER CM-SERIES 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.

Compatibility note: Please confirm fitment by checking part number DXS494, the Denso style application, and all mounting and pinion dimensions against the vehicle before ordering.
