Application and Buying Notes

Use the part number 19020612 first when checking replacement suitability, then compare the mounting style and dimensions against the removed unit. The listed twin leg mount, 61mm inside mounting legs, 157mm mount centre to centre, 16mm mount leg thickness, 6mm adjusting hole diameter, and 8mm pivot hole diameter are the most practical measurements for a physical match.

The electrical details also matter. This alternator is 12V with a 70A power rating, an internal regulator, and an IR44 pin code. Those items should align with the vehicle’s charging system requirements and the original alternator specification before purchase.

Pulley details need checking as well. The unit has a 6 groove pulley with a 55mm outside diameter, so it is sensible to compare belt type and pulley size against the existing alternator. If the belt arrangement does not match, the alternator may not be suitable even where the mounting pattern appears close.

Because no vehicle applications are supplied here, the safest approach is to confirm fitment using the part number, the 7SI series, and the physical measurements listed above. If there is any doubt, compare the old unit directly or have the application verified before fitting.

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 19020612 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.
