OEX Starter Motor 12V 13 Tooth CW Mitsubishi Style MXS273

The OEX MXS273 is a 12V starter motor with 13 teeth and clockwise rotation, listed as a Mitsubishi style unit. It is a new starter motor, supplied as each, with a 2.7kW power rating and a dry clutch application.

Key measurements include 145mm mount centres A, 105mm mount centres B, 105mm mount centres C, a 100mm flange diameter and a 240mm overall length. The starter mount type is 3 hole, with a 13.5mm mount hole diameter and a 30mm pinion at rest.

This unit is intended for Mitsubishi applications and is also shown against a range of industrial and light commercial fitments, including Komatsu, Mitsubishi Fuso, Sumitomo and Yale references. Because starter fitment depends on mount pattern, pinion dimensions and rotation as well as vehicle details, the part number MXS273 should always be checked carefully before purchase.

Application and Buying Notes

When matching a starter motor, the important checkpoints are the part number MXS273, the 12V system voltage, 13 tooth pinion, clockwise rotation and the 3 hole mount layout. This unit also carries 145mm mount centres A, 105mm mount centres B and C, and a 100mm flange diameter, so the physical mounting points must line up with the vehicle or machine already fitted.

The listed applications include Komatsu FD20, FD23, FD25 and FD28, plus Mitsubishi Fuso Fighter, Sumitomo forklift and Yale DB, DE and FD 20P-25P references. Those names are useful guides, but starter motors still need a direct cross-check against the existing unit because mount centres, pinion size, overall length and rotation must all match for the part to suit properly.

At 240mm overall length and 5.88kg, the MXS273 is a substantial rotating electrical component rather than a universal-fit item. If the unit on the vehicle has different mount hole diameter, flange diameter, pinion diameter or tooth count, it should not be assumed compatible. Verifying the existing starter against these measurements is the safest way to avoid a mismatch.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That may be helpful when comparing supply options, but it does not replace checking the fitment details. For a starter motor, the correct application matters just as much as the electrical specification, especially where Mitsubishi style units are used across different equipment families.

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 MXS273 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 13Th CW Mitsubishi Style. Part number MXS273 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 MXS273, 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 KOMATSU FD20, KOMATSU FD20 1980, KOMATSU FD23, KOMATSU FD23 1980, MITSUBISHI FUSO FIGHTER, MITSUBISHI FUSO FIGHTER 1989. 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 the part number MXS273, 12V voltage, 13 tooth clockwise configuration, 3 hole mount type and the listed measurements before ordering. Always compare the existing starter motor and the vehicle or machine application carefully.
