OEX Starter Motor 12V 11T CW Mitsubishi Style MXS300

The OEX MXS300 is a new 12V starter motor in Mitsubishi style, set up with clockwise rotation, 11 teeth, and a 2-hole starter mount. Key sizing details include a 110mm mount centres measurement, 74mm flange diameter, 12mm mount hole diameter, and 211mm overall length, so it is worth checking the existing unit carefully before ordering.

This unit is rated at 1.4kW and weighs 4.02kg. The pinion diameter is 34mm with a 20mm pinion at rest, which are useful checkpoints when comparing against the removed starter motor. The listed OEM number is M1T66081 and the OEX part number is MXS300.

OEX states its products are sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, and from ISO certified factories. The starter is backed by a 3-year passenger / 1-year commercial warranty, making it a considered replacement option where the application, rotation, teeth count, and mounting pattern all match the vehicle.

Fitment is listed for Mitsubishi-style applications across machinery and equipment brands including Allight, Case IH, Ford, Gehl, International, John Deere, New Holland, Perkins, Shibaura, and Yanmar. Because the fitment list is broad, the safest approach is to compare the part number, starter layout, and measurements on the removed unit before purchase.

Application and Buying Notes

When replacing a starter motor, the important checks are the part number, rotation, tooth count, mounting style, and physical dimensions. For this unit, the key identifiers are OEX MXS300, OEM number M1T66081, 12V voltage, 11 teeth, clockwise rotation, and a 2-hole mount with 110mm mount centres.

The physical measurements are just as important as the application list. The flange diameter is 74mm, mount hole diameter is 12mm, overall length is 211mm, and the pinion diameter is 34mm with 20mm pinion at rest. Those details help confirm whether the starter will align correctly with the flywheel and the existing mounting point.

This starter is listed as Mitsubishi style, so it is sensible to compare the removed unit side-by-side before fitting, especially where the machine model can have multiple starter variations. If the old starter is available, match the teeth count, clocking, mounting holes, and the measured dimensions rather than relying on the vehicle model alone.

The listed fitment covers a wide mix of equipment and tractor applications, but that still does not replace a direct check on the vehicle. If your application has been altered, repaired, or fitted with a non-original starter in the past, the safest confirmation is still the part number and the unit dimensions above.

The 1.4kW power rating and dry clutch listing are useful when comparing against an existing replacement, but they should be treated as matching points rather than assumptions. For best results, confirm the starting system is 12V and that the starter’s CW rotation matches the removed component exactly 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 MXS300 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 11Th CW Mitsubishi Style. Part number MXS300 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 MXS300, 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 ALLIGHT MS10K, ALLIGHT MS10K 1980, ALLIGHT MS12K, ALLIGHT MS12K 1980, CASE IH DX, CASE IH DX 2006. 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 compatibility using the OEX part number MXS300, OEM number M1T66081, and the full set of measurements and application details above before purchase. Do not rely on model name alone, as starter variations can differ within the same machine series.
