Application and Buying Notes

Before ordering, compare the existing alternator against Part No. 8600313 and check the mounting layout carefully. This unit is a 28SI with a 198mm mount centre to centre measurement, 101mm inside mounting legs, a 13mm pivot hole diameter, and a 1/2 UNC adjusting hole, so those dimensions need to align with the vehicle or machine.

The alternator is rated at 12V and 200A, so it is intended for applications that match that electrical setup. The internal regulator and self exciting note are useful identifiers, but they do not replace a physical check of the mount type, shaft diameter, and clearance around the installation point.

Because fitment is listed across a broad range of agricultural, industrial, and heavy vehicle applications, model names alone should not be treated as the final check. Confirm the application against the part number, series, mount style, and dimensions before fitting, especially where previous repairs or alternator swaps may have changed the original setup.

If you are replacing an existing Delco unit, match the 22mm shaft diameter, twin leg mount, and the 9.3kg unit weight as part of your comparison. These details help narrow down compatibility when several alternators may look similar but differ in mounting or electrical configuration.

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 8600313 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.

For part number 8600313, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 200 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by checking Part No. 8600313, the 28SI series, 12V 200A rating, twin leg mount, and the stated mounting dimensions against the unit being replaced.
