Application and Buying Notes

When checking this alternator for a replacement job, start with the part number 19020608 and OEM number 19020608. Those identifiers are the clearest match points available here, especially where the existing unit is already Delco Remy or the vehicle uses a Delco alternator arrangement.

Mounting details also matter. This unit is listed with a single leg alternator mount, a mount leg thickness of 50.5mm, a pivot hole diameter of 10, and an adjusting hole diameter of M8 x 1.25mm. If the bracket style or hole sizes do not line up, the alternator may not suit without modification.

The pulley and electrical setup should be checked before purchase. The pulley outside diameter is 69mm, the pulley section is A, the regulator type is internal, and the rotation is clockwise. Matching these details helps avoid problems where the electrical output or belt alignment differs from the original part.

The 70A output and 12V rating make this a straightforward replacement only where those electrical values are appropriate for the system. It is also noted as suitable for marine applications, so the intended use should be considered alongside the physical fit and charging requirements of the application.

As with any rotating electrical part, confirm the original unit’s dimensions and configuration rather than relying on appearance alone. The listed weight of 4.1kg, the 7SI series, and the IR177 pin code can all help when comparing the replacement against the part currently fitted.

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 19020608 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.
