Application and Buying Notes

Before ordering, compare the part number 439816 and OEM number FG23S065 with the alternator currently fitted to the vehicle. The mounting details matter here: this unit is a Quad Leg alternator with four-point mounting, 60mm inside mounting legs, and 90mm mount centres, so physical alignment needs to match exactly.

The pulley setup is also important. This alternator uses a 6 groove pulley with a 57mm outside diameter, so the belt profile and pulley size need to suit the application. The listed pin code is IR228, and the connector note states there is no connector for revolution counter, which should be checked against the vehicle’s charging and wiring arrangement.

Because the unit is rated at 220A on a 12V system, it is intended for a vehicle that originally uses this output and charging configuration. If the existing alternator differs in amperage, pulley style, regulator type, or mount layout, it should be matched carefully before purchase. The one year warranty applies to the part as supplied and does not replace the need to confirm compatibility beforehand.

For the best result, compare the old unit and this listing side by side, including the adjusting hole diameter of 8.5mm, the pivot hole diameter of 8 / M8, and the 7.48kg weight. These details are often the quickest way to confirm whether the alternator is the correct physical and electrical match for the vehicle.

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 439816 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.
