OEX Starter Motor 12V 17T CCW Mitsuba Style SMX043

The OEX Starter Motor SMX043 is a 12V starter motor in a Mitsuba style, set up with 17 teeth and counter-clockwise rotation. It is a new unit, with a 2 hole starter mount, 48mm mount centres, and a 56mm flange diameter, so the mounting pattern and physical dimensions can be checked before ordering.

This starter motor has a .4kW power rating, a 39mm pinion diameter, and 5mm pinion at rest measurement. The overall length is 164mm and the unit weight is 1.74kg, which are useful checks when comparing against the removed part or confirming a replacement for a close-fitting application.

OEX positions this as a quality replacement starter motor for the Australian automotive aftermarket. The listed warranty is 3 years for passenger use or 1 year for commercial use, and the part is identified as SMX043 under the OEX brand.

The stated suit is Mitsuba, which makes the part number, mount type, tooth count, rotation direction, and dimensions especially important when matching the starter to the correct application. As with any starter motor purchase, the safest approach is to confirm the physical details against the existing unit before fitting.

Application and Buying Notes

Before buying, compare the removed starter against the listed identifiers: SMX043, Mitsuba style, 12V, 17 teeth, CCW rotation, and the 2 hole mount. The physical measurements matter as much as the electrical details here, especially the 48mm mount centres, 56mm flange diameter, 164mm overall length, and 39mm pinion diameter.

This starter is a .4kW unit, so it is intended to match the original application rather than serve as a performance upgrade. Matching the pinion at rest measurement of 5mm can also help when checking whether the starter sits correctly relative to the ring gear and mounting face.

The stated suit is for Mitsuba units, so if your existing part is from a different make or has a different tooth count or rotation direction, do not assume interchangeability. Starter motors can look similar while differing in mount spacing, flange size, or pinion setup, which is why the part number and physical dimensions should be checked together.

The warranty differs by use type: 3 years for passenger applications and 1 year for commercial use. If the vehicle or machine is used commercially, it is worth noting that the commercial warranty term is shorter, so the application should be considered carefully before purchase.

For fitment-confirmed applications such as CORMIDI 40, DYNAPAC DFP11/9, HONDA SMALL GX160, HONDA TRX500, HUSQVARNA CONSTRUCTION LF100L/LAT, LF130LT, LF75L/LAT, LF80L/LAT, LX90, YAWIN YW168E and YW168F, confirm the exact model and model year shown against your machine, then cross-check the starter specifications before ordering.

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 SMX043 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.

Additional published details for cross-checking include Product Group 2 STARTER MOTORS, Part No. SMX043, Brand OEX, Description OEX Starter Motor 12V 17Th CCW Mitsuba Style, Flange Diameter 56mm, Number of Teeth 17, Pinion at Rest 5mm, Power Rating .4kW, Suits Unit Make Mitsuba.

OEX Starter Motor 12V 17Th CCW Mitsuba Style. Part number SMX043 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 SMX043, 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 CORMIDI 40, CORMIDI 40 2018, DYNAPAC DFP11/9, DYNAPAC DFP11/9 2017, HONDA SMALL, HONDA SMALL GX160. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment using part number SMX043, Mitsuba style, 12V, 17T, CCW rotation, and the listed mount and dimensional measurements against your original starter motor and application details before purchase.
