Application and Buying Notes

Confirm the part number MXS820 against the old starter motor and compare the measured details before ordering. The critical identifiers here are 12V, 9 teeth, clockwise rotation, 2 hole mount, 205mm overall length, and 125mm mount centre to centre.

This unit is described as Mitsuba style and suits Mitsuba units, but that alone is not enough to confirm fitment on its own. The flange diameter of 75mm, pinion diameter of 29mm, and pinion at rest of 32mm are useful checks when comparing the replacement to the original part.

The listed note is important: low voltage at the starter can cause the solenoid contacts to chatter and burn. Battery condition and cables should be checked before fitting the new starter motor, especially if the original fault may have been caused by voltage drop rather than a failed starter alone.

The starter is a dry type and is listed for a 12V system, so it needs to match the vehicle’s electrical setup and starter configuration. If the removed unit differs in rotation, tooth count, mounting pattern, or physical size, pause and recheck before installation.

For commercial use, the listed warranty is 1 year, while passenger use is listed at 3 years. Keep proof of purchase and confirm the application details at the time of sale so the correct warranty basis is understood from the start.

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 MXS820 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 Mitsuba Style - See Note. Part number MXS820 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 MXS820, 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Confirm fitment by matching the MXS820 part number, 12V specification, CW rotation, 9-tooth pinion, 2 hole mount, and the listed dimensions against the vehicle and removed starter before ordering.
