OEX Starter Motor 24V 11 Tooth CW Mitsubishi Style MXS9603

The OEX MXS9603 is a 24V starter motor with clockwise rotation, 11 teeth, and a 6kW power rating. It is listed as a new unit with a 3-hole starter mount type, 100mm flange diameter, and an overall length of 330mm, so the physical dimensions matter as much as the electrical specification when matching it to the vehicle or machine.

This starter is described as Mitsubishi style and suits unit make Mitsubishi. The fitment information supplied also links it to a range of industrial and commercial applications across Mitsubishi Fuso, Mitsubishi industrial equipment, Hitachi, Kato, Kobelco, Hidromek, and Sumitomo models, but it should still be checked against the part number MXS9603 and the measured mounting details before purchase.

For installation planning, the key identifiers are 24V, CW rotation, 11 teeth, 6kW, Mount Centres A 149mm, Mount Centres B 133mm, Mount Centres C 108mm, and a pinion at rest measurement of 70mm. Those details are the best starting point for confirming that the starter matches the original unit and the application on the machine.

Application and Buying Notes

When comparing this starter to the original unit, start with the part number MXS9603, then confirm the electrical and physical details: 24V supply, clockwise rotation, 11 teeth, 6kW output, and a 3-hole mount with centres at 149mm, 133mm, and 108mm. A starter can look similar and still be wrong if the mount pattern, pinion position, or rotation does not match.

The supplied fitment information points to multiple industrial and commercial applications, including Mitsubishi Fuso, Mitsubishi Industrial, Hitachi, Kato, Kobelco, Hidromek, and Sumitomo listings. That makes direct comparison important, especially where the machine is older or has had previous repairs, because starter styles, tooth counts, and mounting arrangements can vary between unit builds.

The note supplied with this item states that 11 tooth and 13 tooth units are interchangeable. Even so, it is still wise to confirm the original starter’s tooth count, rotation, flange diameter, mount hole diameter, and overall length of 330mm before fitting. Matching those measurements reduces the chance of a mismatch at installation.

The starter is listed as a dry unit and weighs 12.06kg, which can help when cross-checking against the removed component. If you are replacing a failed starter, compare the old unit side by side where possible and look closely at the mounting face, pinion measurement of 70mm at rest, and the 48mm pinion diameter to make sure the replacement is consistent with the original application.

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 MXS9603 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 24V 11Th CW Mitsubishi Style. Part number MXS9603 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number MXS9603, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.
