Delphi Alternator 12V 120A 55302598

The Delphi Alternator 12V 120A is a new alternator with part number 55302598, supplied as each and covered by a one year warranty. It is listed as a Delphi unit with an internal regulator, 12 volt charging system, and 120 amp power rating, so it suits applications that need a replacement alternator to match those core electrical details.

This unit is configured with a 6 groove pulley, clockwise rotation, and a pulley outside diameter of 61mm. The mounting arrangement is a twin leg alternator mount with inside mounting legs measuring 57mm, and the adjusting hole diameter is M10 x 1.5. Those measurements matter when checking physical interchange, because alternators can differ even when they appear similar at first glance.

For identification and cross-checking, the supplied pin code is IR215 and the unit is marked as Delphi for a Delphi unit make. If you are comparing against an existing alternator, the safest approach is to verify the part number 55302598, the 12V 120A rating, the 6 groove pulley, and the twin leg mounting details before ordering.

Application and Buying Notes

Before ordering, compare the existing alternator against the key identifiers here: Delphi part number 55302598, 12V charging system, 120A output, 6 groove pulley, and clockwise rotation. These details are the most useful starting points when confirming whether a replacement alternator is the right match for your vehicle or equipment.

Mounting and pulley measurements should be checked carefully because they affect physical fit. This alternator uses a twin leg mount, inside mounting legs of 57mm, an M10 x 1.5 adjusting hole, and a 61mm pulley outside diameter. If any of those points differ from the unit being replaced, the part may not suit the application even if the connector or appearance seems close.

The internal regulator is another important detail to confirm. Some charging systems are designed around an internal regulator arrangement, while others are not. Matching the regulator type, rotation direction, pulley configuration, and output rating helps reduce the risk of ordering the wrong alternator and means the replacement is assessed on the same specifications as the original unit.

If you are unsure, use the part number from the old alternator or the vehicle's original electrical component information to compare against 55302598. When fitment data is not supplied, the most reliable purchase check is the combination of part number, voltage, amperage, mount style, pulley section, and rotation.

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 55302598 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.

Delphi Alternator 12V 120A. Part number 55302598 should be checked first. Listed voltage is 12. Listed output rating is 120. 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. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 55302598, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number 55302598, the 12V 120A specification, twin leg mount, 6 groove pulley, clockwise rotation, and the listed mounting measurements before purchase.
