Application and Buying Notes

Before ordering, check the part number 439070 against the alternator already fitted to the vehicle. The listed application is BMW 320i with M50B20 engine, so matching the engine code and the mounting style is important rather than relying on appearance alone.

Confirm the alternator mount is twin leg and that the inside mounting legs measure 76mm. The pulley is a 6 groove design with a 50mm outside diameter, so belt alignment and groove count need to suit the existing drive arrangement.

This unit is specified as 12V and 80A with an internal regulator. Those electrical details matter when comparing against the original charging system, especially where the vehicle has been modified or where a different output alternator has been fitted previously.

The connector / clamp is listed as with Revcounter Coupling, so the plug arrangement should be checked carefully before purchase. The alternator is new and supplied with a one year warranty, but correct application remains the buyer's responsibility.

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 439070 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.
