Prestolite Alternator 12V 65A 8MR2402L

The Prestolite Alternator 12V 65A, part number 8MR2402L, is a new rotating electrical unit with an internal regulator and a 65 amp power rating. It is listed as a single leg mount alternator with a 12 volt output, suitable for applications that call for this exact configuration.

Key dimensions include a 27mm mount leg thickness, 16mm shaft diameter, 165mm mount centre to centre, 13mm pivot hole diameter, and 5/16 UNC adjusting hole diameter. The unit weighs 5.2kg and is supplied as each, with a one year warranty.

This alternator is noted as self-excite and finished with environmental coating / E-Coat. The pulley section is not applicable, and the unit is described as bi-directional rotation, which are important details to confirm against the original application before ordering.

Application and Buying Notes

For a correct match, compare the part number 8MR2402L and OEM number 201320 with the alternator currently fitted to the machine. The key mount details on this unit are the single leg mount, 165mm centre to centre measurement, 27mm mount leg thickness, and 13mm pivot hole diameter, so those dimensions should be checked carefully against the existing setup.

The electrical side also needs to line up. This alternator is rated at 12V and 65A, and it uses an internal regulator. If the original unit uses a different voltage, regulator arrangement, or mounting style, it should not be treated as interchangeable without checking the application details first.

The note showing self-excite and environmental coating / E-Coat may be useful where the original specification calls for those features, but they do not replace a proper parts check. The shaft diameter is 16mm and the adjusting hole is 5/16 UNC, so those physical points should be matched before fitting.

Although fitment references are shown for some TYM applications, the safest approach is still to confirm the machine model, year, and alternator details on the vehicle itself. The presence of a listed application does not remove the need to verify the part number, mount layout, and electrical requirements.

If you are replacing a worn or failed alternator, compare the old unit side by side where possible. Check the mount leg thickness, shaft diameter, centre-to-centre measurement, and whether the pulley arrangement matches, noting that the pulley section for this alternator is listed as not applicable.

This is a 5.2kg new alternator supplied with a one year warranty. That gives useful context for handling and installation, but the main compatibility checkpoints remain the 12V system, 65A output, internal regulator, single leg mount, and the relevant application details for the machine.

The listed fitment references are the strongest guide available here, but they should be treated as a starting point rather than a blanket promise. Always confirm the machine model and the alternator identification before purchase, especially where industrial applications can vary between builds.

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 8MR2402L 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, Mount Leg Thickness 27mm, Power Rating (Amp) 65, Regulator Type Internal, Shaft Diameter 16mm, Voltage 12, Alternator Mount Single Leg, New / Reman. New.

Additional published details for cross-checking include Weight 5.2kg, Product Group 1 ROTATING ELECTRICAL, Part No. 8MR2402L, Brand PRESTOLITE, Description Prestolite Alternator 12V 65A, Adjusting Hole Diameter 5/16 UNC, Pivot Hole Diameter 13, Pulley Section Not Applicable, Rotation Bi-Directional, Suits Unit Make Prestolite.

Prestolite Alternator 12V 65A. Part number 8MR2402L 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 8MR2402L, 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.

Compatibility note: Confirm fitment by matching part number 8MR2402L, OEM number 201320, and the listed mount and electrical specifications against the unit being replaced. Known references include selected TYM applications, but final compatibility should be verified on the machine before ordering.
