OEX Starter Motor 12V 9 Tooth CCW Denso Style SMX096

The OEX starter motor listed here is a 12V unit with 9 teeth, CCW rotation and a Denso style configuration. It is identified by part number SMX096 and OEM number 428000-0230, so those references are the key checks when matching it to an existing starter motor application.

It is specified as a new starter motor with a 2 hole mount, 10mm mount hole diameter, 206mm overall length, 30mm pinion diameter and 35mm pinion at rest. The unit weight is 3.5kg, which can be useful when comparing against an original part before ordering.

The stated application is to suit Briggs & Stratton and Vanguard 33hp and 40hp V-Twin air cooled engines. That application detail is important, but the safest approach is still to compare the part number, OEM number, mount type and physical dimensions against the unit being replaced.

Application and Buying Notes

For this starter motor, the most reliable match points are SMX096, OEM number 428000-0230, 12V electrical rating and CCW rotation. If your original unit differs in any of these details, especially the tooth count, rotation direction or mounting arrangement, it should be treated as a different part until confirmed.

Physical dimensions matter as much as the electrical details. This unit is listed with an overall length of 206mm, a 30mm pinion diameter, 35mm pinion at rest and a 2 hole mount with 10mm mount holes. Those measurements help verify that the starter will sit correctly and engage as intended in the application.

The stated engine application is Briggs & Stratton and Vanguard 33hp and 40hp V-Twin air cooled engines. Even where that broad application appears to line up, it is still worth checking the starter’s part number and the original unit’s mounting and drive details before purchase, particularly if the machine has had previous repairs or a non-standard replacement fitted.

The one year warranty applies to this OEX starter motor, and the unit is sold individually as each. If you are cross-checking against an existing starter, compare the brand style reference, Denso suitability, mount type and pinion measurements together rather than relying on appearance alone.

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 SMX096 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.

New.

OEX Starter Motor 12V 9Th CCW Denso Style. Part number SMX096 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 SMX096, 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.

Compatibility note: Please confirm fitment by comparing part number SMX096, OEM number 428000-0230, 12V CCW specification, 9 tooth drive, 2 hole mount and the listed measurements against the original starter motor and engine application before ordering.
