OEX Starter Motor 12V 8TH CW Mitsubishi Style MXS399

The OEX Starter Motor MXS399 is a 12V unit with 8 teeth, clockwise rotation and a 1.2kW power rating. It is listed as a new starter motor for Mitsubishi applications and uses a 2 hole starter mount with 137mm mount centres, which are the key checks to make before ordering.

This starter motor has a 74mm flange diameter, a 52mm nose cone length, a 16mm pinion at rest and a 28mm pinion diameter. The mount hole diameter is M10 / 13, and the unit weight is 3.24kg. Those dimensions matter when matching the replacement to the original starter on the vehicle.

OEX notes that its products are sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, and are produced in ISO certified factories. This starter motor is backed by a 3 year passenger and 1 year commercial warranty, which gives useful buying context when comparing replacement options for Mitsubishi-style fitments.

Application and Buying Notes

When replacing a starter motor, the most reliable match is the part number and the physical layout. For this unit, check MXS399, the 12V specification, 8 tooth pinion, clockwise rotation, and the 2 hole mount with 137mm mount centres before you order.

The size details are just as important as the electrical rating. This starter has a 74mm flange diameter, 52mm nose cone length, 16mm pinion at rest and M10 / 13 mount holes, so it is worth comparing those figures with the original starter on the vehicle rather than relying on appearance alone.

Fitment data supplied with this starter shows Mitsubishi as the unit make, with additional application references appearing for Ford Laser, Mazda 626 and Mazda Premacy. Those listed applications should still be checked against the exact vehicle and engine combination, because starter motors can differ by mounting pattern, rotation and pinion specification.

If you are replacing a failed starter, it is sensible to compare the old unit’s tooth count, rotation direction and mounting pattern before fitting. A 1.2kW starter such as this one may look close to another unit, but a mismatch in 8 tooth pinion arrangement, CW rotation or mount centre spacing can stop installation from lining up correctly.

The warranty is 3 years for passenger use and 1 year for commercial use, which is useful to note when the vehicle sees different duty cycles. Keep the invoice, part number and installation details together so any future reference to the replacement is straightforward.

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 MXS399 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.

Additional published details for cross-checking include Weight 3.24kg, Product Group 1 ROTATING ELECTRICAL, Part No. MXS399, Brand OEX, Description OEX Starter Motor 12V 8Th CW Mitsubishi Style, Flange Diameter 74mm, Mount Hole Diameter M10 / 13, Number of Teeth 8, Pinion Diameter 28mm, Rotation CW.

OEX Starter Motor 12V 8Th CW Mitsubishi Style. Part number MXS399 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 MXS399, 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 FORD LASER, FORD LASER 1999, FORD LASER 2000, FORD LASER 2001, MAZDA 626, MAZDA 626 1998. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by checking part number MXS399, the 12V rating, 8 tooth CW configuration, 2 hole mount and 137mm mount centres against the original starter and the vehicle application details before purchase.
