OEX Starter Motor 12V 12 Tooth CCW Denso Style SMX086

The OEX SMX086 is a new 12V starter motor in a Denso style configuration with 12 teeth and counter-clockwise rotation. It is a pad mount starter motor with a 54mm flange diameter, 67mm mount centres and a 41mm nose cone length, so the physical dimensions can be checked against the existing unit before ordering.

This unit is listed as suitable for Denso applications and uses a 10mm mount hole diameter. The overall length is 204mm, the pinion diameter is 36mm and the pinion at rest measures 2mm, which are practical identifiers when matching a replacement starter motor to the vehicle or machine already fitted.

OEX backs the product with a 3 year passenger / 1 year commercial warranty. The starter motor is supplied as a new rotating electrical component, with a weight of 3.82kg and a dry clutch setup noted in the specification set.

Application and Buying Notes

For a starter motor replacement, the safest check is to match the part number SMX086 and then compare the mounting and drive details to the unit already fitted. The key measurements here are 67mm mount centres, a 54mm flange diameter, 41mm nose cone length, 204mm overall length and a 10mm mount hole diameter.

The starter is specified as 12V with 12 teeth and CCW rotation. Those details matter because a starter can look close in appearance but still be wrong in tooth count, rotation or nose length. The listed Denso style and pad mount design are also important compatibility checkpoints.

If you are replacing an original starter, compare the pinion diameter of 36mm and the pinion at rest measurement of 2mm against the existing unit. These figures can help confirm that the replacement matches the physical arrangement, particularly where the same model range has been fitted with more than one starter variant.

The supported fitment list includes BOMAG, Ditch Witch, Honda Small, Kanga, Saab and Sakai applications, but the exact match still needs to be checked against the vehicle or machine details already on the unit. Model names alone are not enough, so matching the part number, mount type and rotation is the sensible way to avoid a wrong-order return.

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 SMX086 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 12Th CCW Denso Style. Part number SMX086 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 SMX086, 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 BOMAG BW90, BOMAG BW90 1971, BOMAG BW900, BOMAG BW900 1971, DITCH WITCH SK500, DITCH WITCH SK500 2008. 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: Confirm fitment using part number SMX086, the 12V CCW Denso style configuration, and the measured mount and drive dimensions before purchase. If the existing starter differs in mount centres, flange diameter, tooth count, rotation or nose cone length, it should be treated as a different application.
