OEX Starter Motor 12V 9T CW Mitsubishi Style MXS2031

The OEX Starter Motor MXS2031 is a new 12V starter motor with 9 teeth, clockwise rotation and a Mitsubishi style layout. It is listed with a 2 hole starter mount type, 82mm flange diameter and 105mm mount centres A, so those physical checks matter as much as the voltage when comparing against the original unit.

This unit is rated at 2.5kW and has a pinion at rest measurement of 26mm, with a 35mm pinion diameter and 11mm mount hole diameter. The overall length is 287mm and the starter weighs 6.82kg, which gives a good set of matching points when confirming replacement against the removed starter.

OEX identifies this starter as suitable for Mitsubishi units, and the listed application data also points to a wider range of equipment fitments across Caterpillar, Hitachi, Hyundai Construction, John Deere, Kubota and Merlo applications. Even with that range, the safest purchase is still the one matched by part number MXS2031, 12V specification and the starter’s mounting dimensions.

Application and Buying Notes

Before ordering, compare the removed starter against MXS2031 and check the 12V rating, 9 tooth pinion, clockwise rotation and 2 hole mounting pattern. The physical dimensions matter here: 105mm mount centres A, 82mm flange diameter, 11mm mount hole diameter and 287mm overall length must all line up with the vehicle or machine application.

The pinion at rest measurement of 26mm and pinion diameter of 35mm are useful reference points when confirming the starter nose and engagement area. If the original starter has a different tooth count, rotation direction or mounting face, the unit may not suit even if the vehicle appears in the application list.

The listed fitment covers a broad range of equipment families, but the correct match still depends on the exact application, build arrangement and the starter fitted to the machine. In rotating electrical parts, matching by part number and measurements is the most reliable approach, especially where Mitsubishi style starters are used across different makes.

Warranty is listed as 3 years for passenger use and 1 year for commercial use. If the starter is being fitted to commercial or industrial equipment, make sure the duty cycle and warranty terms are understood before purchase, and keep the part number, application details and mounting measurements on hand for confirmation.

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 MXS2031 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 9Th CW Mitsubishi Style. Part number MXS2031 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 MXS2031, 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 CATERPILLAR 236D, CATERPILLAR 236D 2014, CATERPILLAR 242D, CATERPILLAR 242D 2015, HITACHI LX30-7, HITACHI LX30-7 2003. 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 compatibility by checking part number MXS2031, 12V, 9 tooth CW rotation, 2 hole mounting and the listed dimensions before ordering.
