Application and Buying Notes

Before ordering, compare the part number 439459 with the alternator already fitted to the vehicle. The mounting style on this unit is twin leg with double pivot lever fastening, and the listed measurements of 75mm inside mounting legs and 125mm mount centre to centre need to line up with the vehicle’s bracket arrangement.

The electrical specification is 12V at 150A, so the replacement needs to suit the vehicle’s charging system requirements. The regulator is internal, and the unit is listed with no connector for revolution counter, so connector layout should be checked against the existing alternator before installation.

Pulley details matter just as much as the electrical rating. This alternator has a 55mm outside pulley diameter and a 5 groove pulley section, so belt profile and belt alignment should be verified on the vehicle before purchase.

This alternator is listed for Land Rover Freelander applications with the M47R engine. Even where the vehicle model appears to match, alternator fitment can still vary by engine, mounting pattern, pulley configuration, and electrical connections, so it is best to confirm the old unit and the vehicle’s current setup side by side.

The unit is remanufactured and carries a one year warranty. That gives a clear service period on the part itself, but it does not replace the need to confirm the physical and electrical match before the vehicle is returned to service.

If you are working from a worn or unreadable original alternator, use the part number, mounting measurements, pulley section, and regulator type together. Those details give a much more reliable comparison than vehicle model alone when identifying the correct replacement.

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 439459 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.
