Delco Remy Alternator 12V 200A 28SI 8600314

The Delco Remy Alternator 12V 200A 28SI is a new alternator with an internal regulator, designed for 12 volt electrical systems that need a 200 amp output. It suits Delco applications and carries part number 8600314, which is the key identifier to check before ordering.

This unit uses the 28SI series and is described as self exciting, with a pad mount arrangement, inside mounting legs at 108mm, and mount centre to centre at 190mm. The shaft diameter is 22mm, the shaft dimension is listed as 22, and the pulley section is not applicable.

For buyers matching an existing charging system, the important points here are the 12V rating, 200A power rating, internal regulator, and the specified mounting and shaft measurements. At 8.56kg, it is a substantial rotating electrical component intended to be matched carefully to the vehicle or equipment application.

Application and Buying Notes

Before ordering, confirm that your replacement unit matches part number 8600314, the 28SI series, and the 12V 200A specification. Those three details matter because alternators that look similar can differ in regulation type, mounting layout, and shaft dimensions, even when they are used in the same truck or equipment family.

Check the physical dimensions against the unit on the vehicle: inside mounting legs are 108mm, mount centre to centre is 190mm, mount leg thickness is 80mm, and the shaft diameter is 22mm. The adjusting hole diameter is listed as 10/12, so the bracket and adjustment arrangement should also be compared before purchase.

The internal regulator and self exciting 28 SI note are important when matching charging system behaviour. If the existing alternator uses a different regulator style or mounting arrangement, the unit may not be a direct swap without further confirmation. Confirm the application details carefully rather than relying on appearance alone.

This alternator is supplied new and carries a one year warranty. At 8.56kg, it is not a lightweight accessory part, so handling and installation should be done with care. Matching the stated measurements and pin code IR221 is the safest way to avoid avoidable returns and installation delays.

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 8600314 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 Remy Alternator 12V 200A 28SI. Part number 8600314 should be checked first. Listed voltage is 12. Listed output rating is 200. 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 8600314, 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 fitment using part number 8600314, the 28SI series, 12V 200A rating, 22mm shaft diameter, and the listed mounting measurements before purchase.
