Denso Alternator 24V 95A 021080-0730

This Denso alternator is a new 24V, 95A rotating electrical unit with part number 021080-0730. It uses an internal regulator and is listed with a twin leg alternator mount, making the mounting layout, voltage and output rating clear before you compare it with the unit already fitted.

The listed dimensions are practical checkpoints for a replacement job: inside mounting legs 101mm, mount centre to centre 198mm, shaft diameter 22mm, pivot hole diameter 13mm and adjusting hole diameter 1/2 UNC. It also carries the note Brushless R terminal - 3mm pin, which is worth checking against the existing harness and connection style before ordering.

At 10.46kg, this is a substantial alternator suited to applications that need 24 volt charging and a 95 amp output. The product is described as new, sold each, and backed by a one year warranty. For buyers comparing options, the Denso brand, the 021080-0730 part number and the physical mount dimensions are the main identifiers to confirm first.

Application and Buying Notes

Before ordering, compare the 021080-0730 part number, 24V system voltage and 95A output with the unit in the machine. A 24 volt alternator is not interchangeable with a 12 volt charging setup, and the amp rating should be checked against the electrical demand of the application rather than assumed.

The mounting details matter just as much as the electrical rating. Confirm the twin leg mount, 101mm inside mounting legs, 198mm centre to centre measurement, 22mm shaft diameter and the 13mm pivot hole. If any of those dimensions differ from the old alternator, the unit may not sit correctly or align as expected.

The note Brushless R terminal - 3mm pin is another important checkpoint. That connection style should match the existing wiring arrangement, otherwise the alternator may not connect cleanly without modification. The internal regulator specification should also be matched to the vehicle or machine setup rather than treated as a generic replacement feature.

This alternator is listed against a range of Atlas Copco, Barko, Bomag, Case and Caterpillar applications, but those references still need to be checked against the exact machine model and existing unit. When a part is used across several equipment families, the safest approach is to verify the part number, mount type and terminal detail before purchase.

The weight is 10.46kg, which gives a reasonable sense of the unit size and handling requirements during installation. Because this is a new Denso alternator with a one year warranty, it suits buyers who want a direct replacement candidate with clear dimensional checks rather than a guess based on appearance alone.

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 021080-0730 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Inside Mounting Legs 101mm, Power Rating (Amp) 95, Shaft Diameter 22mm, Voltage 24, Alternator Mount Twin Leg, New / Reman. New, Weight 10.46kg.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. 021080-0730, Brand DENSO, Description Denso Alternator 24V 95A, Adjusting Hole Diameter 1/2 UNC, Pivot Hole Diameter 13, Regulator Type Internal, Suits Unit Make Denso, Note Brushless R terminal - 3mm pin, Mount Cnt to Cnt 198mm.

Denso Alternator 24V 95A. Part number 021080-0730 should be checked first. Listed voltage is 24. Listed output rating is 95. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 021080-0730, 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 95 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include ATLAS COPCO MT5020, ATLAS COPCO MT6020, ATLAS COPCO ROC D7-RRC, BARKO VARIOUS, BOMAG BM1200/30, BOMAG BM1300/30. 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 by matching the 021080-0730 part number, 24V rating, 95A output, twin leg mount, and the listed dimensions and terminal note against the alternator currently fitted to the machine.
