Delco Remy Alternator 12V 160A 28SI Pad Mount New Part No. 8600315

This Delco Remy alternator is a new 12V, 160A 28SI unit with internal regulation and pad mounting. It carries part number 8600315, uses rotation marked CW, and is noted as self exciting. For buyers matching an existing charging system, the key checks are the 12V system, 160 amp output, 28SI series, and the Delco unit make.

The alternator is supplied as each, with a weight of 8.58kg, a shaft diameter of 22mm, and mount hole diameter listed as 10 / 12. It also shows inside mounting legs of 108mm and mount leg thickness of 80mm, which are useful reference points when comparing against the existing unit or bracket setup.

This is a Delco Remy rotating electrical component with an internal regulator and no pulley section applicable. It is intended for customers who need a replacement alternator with the same series and mounting details rather than a universal fit unit. As always, part number 8600315 and the physical mounting measurements should be confirmed before ordering.

Application and Buying Notes

The most important buying check on this alternator is matching the part number 8600315 with the existing unit or the required application. The listed specs are specific: 12V system, 160A output, 28SI series, pad mount, internal regulator, and CW rotation. If any of those differ from the vehicle or machine you are working on, confirm the alternator type before fitting.

Physical measurements matter just as much as the electrical rating. This unit lists a 22mm shaft diameter, 190mm mount centre to centre, 108mm inside mounting legs, 80mm mount leg thickness, and 10 / 12mm mount hole diameter. Those figures help compare bracket alignment and mounting compatibility against the existing alternator and surrounding hardware.

The note that the unit will self excite is useful when checking how the charging system is expected to start up and operate. Even so, installation should still be matched to the machine’s charging setup, regulator arrangement, and connector requirements. The pin code is IR189, which may help when comparing terminal layout or ordering against an existing component.

This alternator is listed against multiple heavy vehicle and engine families, but fitment should still be treated as application-specific. The safest approach is to verify the part number, series, voltage, output rating, mounting style, and the measured dimensions before purchase. That is especially important where the original alternator has been changed previously or where the bracket hardware has been modified.

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 8600315 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.

Delco Alternator 12V 160A 28SI. Part number 8600315 should be checked first. Listed voltage is 12. Listed output rating is 160. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 8600315, 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 160 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number 8600315, 12V 160A 28SI specification, pad mount layout, CW rotation, and the listed mounting dimensions against the existing alternator and application details before ordering.
