Delco Remy Alternator 12V 70A 7SI Part No. 19020616

The Delco Remy Alternator 12V 70A 7SI is a new rotating electrical unit supplied as each and identified by Part No. 19020616. It is a 12 volt, 70 amp alternator with an internal regulator, designed around the 7SI series and listed with a single leg mount arrangement.

Key physical details for checking installation include a 51mm mount leg thickness, 168mm mount centre to centre, 10mm pivot hole diameter, and an M8x1.25 adjusting hole. The pulley is 86mm outside diameter with an AA section, and the unit notes a 17mm shaft.

This alternator is listed for Delco applications under the Suits Unit Make field and carries a one year warranty. At 4.8kg, it is a compact electrical component, but alternator fitment still depends on the exact mounting points, pulley arrangement, and shaft detail matching the vehicle or replacement unit required.

Application and Buying Notes

Before ordering, compare Part No. 19020616 with the alternator currently fitted to the vehicle or equipment. The important checks here are the 12V system, 70A output, 7SI series, internal regulator, and single leg mount layout, because these features need to match the application’s charging setup.

Physical dimensions matter just as much as electrical rating. Confirm the 51mm mount leg thickness, 168mm centre to centre measurement, 10mm pivot hole, and M8x1.25 adjuster hole against the existing alternator or bracket. The 86mm AA pulley and 17mm shaft note should also be checked if you are replacing like-for-like.

If the vehicle has been modified, fitted with a different pulley, or previously converted, do not rely on the general description alone. Alternators can look similar while using different mounting geometry or shaft details, so the safest approach is to verify the old unit, the bracket spacing, and the part number before purchase.

The stated one year warranty applies to the unit as supplied, but it does not replace fitment checking. A correct match is usually established by part number and the mounting and pulley specifications, especially when dealing with Delco 7SI alternators used across different applications.

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 19020616 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.
