Prestolite Alternator 24V 55A New No Pulley Part No. 861086

This Prestolite alternator is a new rotating electrical unit rated at 24V and 55A, supplied as each and identified with part no. 861086. It is listed as an OE product, which makes the key identifiers worth checking carefully before purchase, especially the voltage, amperage, and the fact that it is supplied without a pulley.

The stated specification is Prestolite Alternator 24V 55A, with a one year warranty and a new construction. If you are replacing an existing alternator, matching the 24 volt system requirement and the 55 amp output is essential, as these details are part of the electrical application rather than just a general size reference.

This unit is catalogued under rotating electrical and alternators, with the brand and unit make both shown as Prestolite. The note “No Pulley” is important for anyone comparing it with a removed unit, because pulley supply can affect whether the part is ready to install as-is or whether existing components need to be transferred over.

Application and Buying Notes

Before ordering, confirm that the vehicle or equipment uses a 24 volt charging system and that the required alternator output is 55A. The most important identifiers here are the voltage, amperage, and part no. 861086, because those details need to align with the existing application rather than relying on appearance alone.

The “No Pulley” note should be checked against the part being replaced. If your removed alternator includes a pulley arrangement that you intend to reuse, make sure the existing pulley and related mounting details are suitable for transfer. This is a practical point on this listing because the alternator is supplied without a pulley.

Because this is an OE product and a new unit, it is intended for buyers wanting a direct replacement based on the listed electrical specification and part identification. Even so, alternators can vary by application details, so it is sensible to compare the part number, system voltage, output rating, and physical setup before fitting.

If you are matching against a worn or unreadable old part, the safest checkpoints are the Prestolite brand, 24V rating, 55A output, and part no. 861086. These are the verified details provided for this unit, and they are the best reference points for confirming whether it suits your equipment.

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 861086 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 55A. Part number 861086 should be checked first. Listed voltage is 24. Listed output rating is 55. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 861086, 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 55 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Please confirm compatibility by matching part no. 861086, the 24V system requirement, the 55A output rating, and the no pulley note against the existing application before ordering.
