Application and Buying Notes

Before ordering, match the alternator against the vehicle’s existing unit and confirm the part number MXA247 where possible. The important physical checks here are the twin leg mount, 67mm inside mounting legs, 175mm mount centre to centre, M10x1.25 pivot hole, and 5 groove pulley, because these details affect whether the alternator will bolt up and line up correctly.

The output rating is 90 amp at 12V, so it suits applications specified for that electrical capacity. If your current alternator uses a different regulator arrangement, pulley section, shaft dimension, or mounting style, do not rely on appearance alone. Mitsubishi style alternators can vary in the bracket spacing, pulley layout, and connector arrangement.

This unit is described as new and weighs 5.6kg. That makes it sensible to compare the old unit side by side before fitting, especially if you are replacing a component on a Mitsubishi, Mazda, Ford, Eunos, K27 FH-Series, or related application listed against this part.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. If the vehicle is used in a commercial setting, it is worth confirming that the intended application falls within the commercial warranty period before purchase.

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 MXA247 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.
