Application and Buying Notes

Check the part number V30-13-42550 first, then compare the mounting layout, pulley type, and electrical setup against the vehicle currently fitted. This alternator uses an internal regulator, a single leg mount, and a 6 groove pulley, so those details need to line up before purchase.

The listed dimensions matter when confirming the fit. The mount leg thickness is 56mm, the pivot hole diameter is 11mm, the adjusting hole diameter is 11mm, and the mount centre to centre is 156mm. If any of these measurements differ on the vehicle, the alternator may not install correctly without changes.

This unit is rated at 12V and 120A. That output is the key electrical specification to compare with the existing alternator and the vehicle’s charging system requirements. The alternator is new and weighs 6.7kg, which can also help when comparing against the existing part during identification.

The one year warranty applies to the supplied VEMO alternator. For any replacement alternator, the safest approach is to verify the part number, the pulley grooves, the mount style, and the measured dimensions rather than relying on appearance alone.

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 V30-13-42550 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.
