Application and Buying Notes

Before ordering, compare the original alternator’s part number, mounting style, regulator type, and electrical rating against Delco Remy part number 8600017. The important figures here are 24V, 70A, twin leg mount, internal regulator, IR51 pin code, and the 198mm mount centre to centre measurement.

The adjusting hole diameter is listed as 1/2 UNC, so the bracket and adjustment arm need to suit that size. If the mounting points, connector arrangement, or pin code differ from the existing unit, the alternator may not be a direct replacement even if the vehicle model appears similar.

This alternator is a new unit rather than remanufactured, and the one year warranty applies to the item as supplied. For heavy equipment and industrial applications, matching the alternator specification is just as important as matching the machine model, because current output and mounting details can vary within the same model family.

The fitment list includes Boart Longyear LF160, Caterpillar 14G, Cummins QSK19, Dennis Eagle Elite 2, several JCB models, JCB Vibromax VM166D, VM166PD, VM200D and VM200PD, plus Volvo R. Use those applications only as a guide and confirm the exact part number and mounting measurements against the vehicle 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 8600017 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.
