The key physical checks here are the Bosch suitment, internal regulator, quad leg mount, 6 groove pulley, 52mm pulley outside diameter, and the listed 128mm mount centre to centre.\u003c\/p\u003e\n\u003cp\u003eThe recorded pivot hole diameter of M8x1.25 \/ 8.5 and inside mounting legs of 60mm are the kind of measurements that help confirm whether the alternator will physically match the bracket and fixing arrangement. If the old unit differs in pulley section, mounting leg spacing, or regulator type, it should be matched carefully before fitting.\u003c\/p\u003e\n\u003cp\u003eThis alternator is listed at 12V and 140A, so it should be compared to the electrical requirements of the vehicle and the original unit being replaced. Matching output and design details matters on modern charging systems, especially where Bosch components and euro vehicle applications are involved.\u003c\/p\u003e\n\u003cp\u003eThe one year warranty applies to the part as supplied, but warranty cover is not the same as confirming fitment. A successful purchase still depends on checking the part number, mount style, and pulley specification against the vehicle application and the removed alternator.\u003c\/p\u003e\n\u003cp\u003eBefore 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.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number 04L903021GX 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.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Pivot Hole Diameter M8x1.25 \/ 8.5, Pulley Outside Diameter 52mm, Regulator Type Internal, Voltage 12, Item Type Alternator, New \/ Reman.
