Prestolite Alternator 24V 110A 110-459

The Prestolite 24V 110A alternator, part number 110-459, is a new rotating electrical unit supplied as each. It is built with an internal regulator, insulated return, and a twin leg mount arrangement, with 216mm centre-to-centre mounting and 101mm inside mounting legs.

This alternator is rated at 110 amps and 24 volts, with an M12 x 1.75 adjusting hole diameter and a 22mm shaft diameter. The unit weight is 9.62kg, so correct mounting space and bracket alignment should be checked before ordering.

It is described as coated for environmental protection, with a regulator warning lamp terminal, and is noted as a small frame Loadhandler application. The design also includes self excitation, above ground configuration, and E-Coat protection, which are practical identifiers when comparing against a removed unit.

The alternator uses high temperature grease and seals for longer bearing life, along with a fan design intended to improve air flow and support cooler operation under high output load conditions. A one year warranty is listed for the unit.

Application and Buying Notes

The most useful identifiers on this unit are the Prestolite brand, part number 110-459, 24V rating, and 110A output. If the machine originally used a Prestolite alternator in this specification range, the part number and the physical mounting layout are the first details to confirm.

Mounting dimensions matter just as much as electrical rating. This alternator uses a twin leg mount, 216mm centre-to-centre mounting, 101mm inside mounting legs, and an M12 x 1.75 adjusting hole diameter. If any of those points differ from the existing unit, the alternator may not align correctly.

Electrical features also need to line up with the vehicle’s charging system. This unit has an internal regulator, insulated return, and a regulator warning lamp terminal. Those details should be matched to the original arrangement so the charging system and warning circuit operate as intended.

The unit is listed as above ground, self excitation, and coated for environmental protection, with high temperature grease and seals for longer bearing life. These are useful construction details, but they do not replace fitment checking, especially on heavy equipment where bracket style and wiring setup can vary between models and years.

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 110-459 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.

Prestolite Alternator 24V 110A. Part number 110-459 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 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 110-459, 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 992, CATERPILLAR 992 1994, CATERPILLAR 992 1995, CATERPILLAR 992 1996, CHAMPION 710A, CHAMPION 710A 1989. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching the part number 110-459, the 24V 110A specification, and the mounting and electrical details against the removed alternator and machine application before ordering.
