Delco Remy Alternator 24V 110A 28SI Part No. 8600469

The Delco Remy Alternator 24V 110A 28SI is a new alternator supplied as a 24 volt, 110 amp unit for rotating electrical applications that need a pad mount layout. It carries part number 8600469 and is listed with an internal regulator, which is an important checkpoint when matching the replacement to the vehicle or machine already fitted.

This alternator uses the 28SI series and has inside mounting legs measured at 108mm, with mount centre to centre also listed at 108mm. Other measured details include a 10/12 adjusting hole diameter, 80mm mount leg thickness, a 22mm shaft diameter, and an 8.56kg weight. Those figures matter when confirming physical interchange, especially on equipment where bracket spacing and mounting style need to line up exactly.

Delco Remy describes this unit as a premium quality alternator designed to increase efficiency. The pulley section is listed as not applicable, so the key compatibility checks are the 24V electrical system, 110A output, pad mount arrangement, internal regulator type, and the part number 8600469 rather than assuming similarity from appearance alone.

Application and Buying Notes

Before ordering, confirm the machine uses a 24 volt charging system and that the replacement alternator is meant to be a 110 amp unit. The mounting details are also critical here: this alternator is a pad mount design with inside mounting legs at 108mm, mount centre to centre at 108mm, and an 80mm mount leg thickness. If those measurements do not match the fitted unit, the alternator may not install correctly even if the brand looks familiar.

The internal regulator is another important point. Some charging systems rely on a different regulator arrangement, so matching the regulator type avoids unnecessary returns and wiring issues. The shaft diameter is listed at 22mm and the pulley section is not applicable, so the mechanical connection should be checked against the existing unit rather than assumed from the series name alone.

For buyers comparing options, the safest reference is part number 8600469 together with the 28SI series and the listed application details. The fitment references include Caterpillar 814K, 924K, 930K, a range of Caterpillar Agricultural machines, and several Caterpillar AP and M series applications, but final confirmation still depends on the exact machine specification and the alternator currently installed.

Because this is a new Delco Remy alternator, it is intended as a replacement component rather than a remanufactured exchange unit. The listed weight is 8.56kg, which can be useful when checking freight handling or comparing against the removed alternator during bench inspection. A one year warranty is listed, but correct identification against the vehicle or equipment remains the buyer’s responsibility before purchase.

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 8600469 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.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. 8600469, Brand DELCO REMY, Description Delco Remy Alternator 24V 110A 28SI, Adjusting Hole Diameter 10/12, Mount Leg Thickness 80mm, Power Rating (Amp) 110, Regulator Type Internal, Shaft Diameter 22mm.

Delco Remy Alternator 24V 110A 28SI. Part number 8600469 should be checked first. Listed voltage is 24. Listed output rating is 110. 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 8600469, 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 24 and output 110 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CATERPILLAR 814K, CATERPILLAR 814K 2014, CATERPILLAR 924K, CATERPILLAR 924K 2011. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment using part number 8600469, the 28SI series, 24V 110A rating, pad mount arrangement, and the 108mm mounting measurements before ordering.
