Application and Buying Notes

When matching this alternator, start with the part number 1800A452 and compare it with the original unit removed from the vehicle. The mounting layout is specific: twin leg mount, 54mm inside mounting legs and 184mm centre-to-centre across the mount points, so those measurements need to align with the existing bracket arrangement.

The electrical side also needs checking. This unit is a 12V alternator with a 105A output and an internal regulator. If the replacement vehicle uses a different regulation setup, or a different amperage rating, the alternator may not be suitable even if the housing looks similar.

Pulley detail matters as well. The listed pulley is 55mm outside diameter with 6 grooves, so belt alignment and belt style must be confirmed against the current alternator. The pivot hole is 10mm and the adjusting hole is 10.5mm, both of which are useful reference points when verifying the fit before fitting begins.

For buyers working from a vehicle application rather than a removed part, use the Mitsubishi listing and any original part numbers together. If there is any doubt about the exact model or engine setup, compare the physical unit, mounting points, pulley style and regulator type before ordering. That is the safest way to avoid an unnecessary return on an electrical part.

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 1800A452 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.
