OEX Starter Motor 12V 1.6KW 15 Tooth CW Mitsubishi Style MXS9618

The OEX starter motor MXS9618 is a new 12V unit with a 1.6kW power rating, 15 teeth, and clockwise rotation. It is listed as a Mitsubishi style starter motor with a 2 hole mount, 105mm mount centres, and M10x1.25 mount hole diameter, so the key checks before purchase are the mounting pattern, pinion details, and electrical specification.

Physical dimensions matter on starters, especially when you are matching a replacement rather than changing a system. This unit measures 229mm overall length, has a 76mm flange diameter, a 44mm pinion diameter, and 18mm pinion at rest, with a weight of 4.8kg. Those figures are important when comparing against the removed part.

The application information supplied with this starter motor includes several small machinery and equipment makes and models, including CASE, Caterpillar, Hyundai Construction, Kobelco, New Holland, Terex O&K, and Toro. Because it is a Mitsubishi style starter, the part number MXS9618 and the listed dimensions should be used together when confirming the correct replacement.

Application and Buying Notes

Before ordering, compare the removed starter against the supplied details: 12V, 1.6kW, 15 teeth, clockwise rotation, and a 2 hole mount with 105mm mount centres. A starter can look similar across different applications, but a mismatch in rotation, tooth count, or mounting pattern can prevent correct installation.

The listed dimensions are also practical checks. This unit is 229mm long, has a 76mm flange diameter, a 44mm pinion diameter, and an 18mm pinion at rest. If your original starter differs meaningfully in these areas, it is worth re-checking the application before purchase.

Fitment is supplied for a range of compact equipment applications, including CASE CX15B II, Caterpillar 301.6C and 301.8C, Hyundai Construction R16-9 and ROBEX models, Kobelco SK17SR and SK17SR-3, New Holland E16B, E18B and E18SR, Terex O&K TC16 and TC20, and Toro Groundsmaster, Reelmaster and Workman models. Use the part number MXS9618 and the physical measurements together, rather than relying on model name alone.

The unit is listed as new, with a one year warranty. For starter motors, that makes it especially important to confirm the vehicle or machine uses a Mitsubishi style starter with the same mounting, tooth count, and clockwise rotation before fitting. If you are unsure, compare the old unit side by side or check with the machine serial number and parts listing.

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 MXS9618 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 15Th CW Mitsubishi Style. Part number MXS9618 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 MXS9618, 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 CASE CX15B II, CASE CX15B II 2008, CASE CX17B, CASE CX17B 2007, CATERPILLAR 301.6C, CATERPILLAR 301.6C 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: Confirm fitment using part number MXS9618, the 12V 1.6kW specification, 15 tooth clockwise rotation, and the 2 hole mount with 105mm centres before ordering. If the removed starter or machine listing does not match these details, re-check the application first.
