Prestolite Alternator 12V 65A 110-646

The Prestolite 12V 65A alternator is a new unit supplied under part number 110-646 and OEM number 8MR2316L. It is a single leg mount alternator with a 16mm shaft, 27mm mount leg thickness and a 160mm mount centre-to-centre dimension, so those physical points are worth checking against the original unit before ordering.

This alternator uses an internal regulator and is marked for CCW rotation only. It is also listed with a 5/16 UNC adjusting hole diameter and a 13mm pivot hole diameter, which are the kind of mounting details that help confirm whether the unit is a direct match for the application.

At 12 volts and 65 amps, this Prestolite alternator suits a specific electrical setup rather than a one-size-fits-all replacement. The unit is coated for environmental protection and described as new, with a one year warranty.

The supplied application information points to Carrier and Carrier Transcold use, including Carrier Transcold references across multiple model years. Because alternators can share similar appearance while differing in rotation, mounting and pulley arrangement, the part number, rotation direction and mounting measurements should be confirmed carefully before purchase.

Application and Buying Notes

Before ordering, compare the part number 110-646 and OEM number 8MR2316L with the alternator currently fitted to the vehicle or equipment. The most important checks on this unit are the CCW rotation, internal regulator, 12V rating and the single leg mount layout with 160mm mount centre-to-centre.

The mounting dimensions matter as much as the electrical rating. This alternator has a 27mm mount leg thickness, 13mm pivot hole diameter, and a 5/16 UNC adjusting hole diameter, so a visual match is not enough on its own. Measure the existing alternator and confirm the fixing points line up before fitting.

The 65A output suits the stated application, but output capacity only helps if the rest of the charging system is matched correctly. Confirm the pulley arrangement is not required here, as this unit is listed with pulley section not applicable, and make sure the replacement follows the same rotation direction and regulator type as the original.

The unit is supplied new and carries a one year warranty. Features such as self excitation, E-Coat coating, high temperature grease and seals, and the fan design for improved airflow are useful product details, but they do not replace the need to confirm fitment against the original alternator and application details.

For Carrier and Carrier Transcold applications, use the vehicle or equipment identification, the existing alternator part number, and the physical dimensions together. That is the safest way to avoid ordering a similar-looking alternator that differs in shaft size, rotation, or mounting arrangement.

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 110-646 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 Shaft Dimension 16, Product Group 2 ALTERNATORS, Part No. 110-646, Brand PRESTOLITE, Description Prestolite Alternator 12V 65A, Adjusting Hole Diameter 5/16 UNC, Pivot Hole Diameter 13, Pulley Section Not Applicable, Rotation CCW.

Prestolite Alternator 12V 65A. Part number 110-646 should be checked first. Listed voltage is 12. Listed output rating is 65. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. 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 110-646, 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 65 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CARRIER TRANSCOLD, CARRIER TRANSCOLD 1979, CARRIER TRANSCOLD 1994, CARRIER TRANSCOLD 1996. 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: Please confirm fitment using part number 110-646, OEM number 8MR2316L, CCW rotation, internal regulator, and the stated mounting dimensions before ordering. Application details supplied here point to Carrier and Carrier Transcold, but final compatibility should always be checked against the original unit and equipment details.
