OEX Alternator 24V 140A Prestolite Plus PLX100 BLD3314GHPLX100

The OEX Alternator BLD3314GHPLX100 is a new 24V, 140A heavy commercial alternator built for Prestolite applications and supplied with the PLX100 pulley. It uses a twin leg mount, has an internal regulator, and is listed with insulated return, so matching the electrical setup and mounting arrangement is important before purchase.

This unit is specified with a 10 groove pulley, 80mm pulley outside diameter, 22mm shaft diameter, 101mm inside mounting legs, and 216mm mount centre to centre. Those dimensions matter on heavy commercial charging systems where bracket spacing, pulley alignment, and shaft fit all need to line up with the existing setup.

The alternator is described as a brushless unit and is sold as each. It is backed by a one year warranty. For buyers replacing an existing Prestolite alternator, the part number BLD3314GHPLX100 and the PLX100 pulley detail are the key identifiers to check against the vehicle or equipment currently fitted.

Application and Buying Notes

Before ordering, compare the part number BLD3314GHPLX100 with the alternator currently fitted, along with the Prestolite application details. The important checks here are the 24V system voltage, 140A output, twin leg mounting, and the supplied PLX100 pulley, because those items need to match the existing charging setup for a proper installation.

Mounting measurements are often the deciding factors on heavy commercial alternators. This unit is listed with 101mm inside mounting legs, 216mm mount centre to centre, a 1/2 UNC adjusting hole, and a 13mm pivot hole. If any of those points differ from the alternator being replaced, the unit may not line up correctly even if the connector or housing looks similar.

Pulley and shaft details should also be checked carefully. The alternator has a 10 groove pulley, 80mm pulley outside diameter, and 22mm shaft diameter. Those figures are especially relevant where belt alignment, belt type, and pulley fit need to remain consistent with the original setup.

The internal regulator and insulated return are useful identifiers when matching the charging system specification. They do not remove the need to verify the existing wiring arrangement, mounting style, and alternator family. In commercial applications, a close visual match is not enough on its own; the measured details and part number should be confirmed before fitment.

This is a new OEX unit and is listed as a brushless alternator. The one year warranty provides added assurance, but it does not replace the need to confirm compatibility at the vehicle or equipment level. If the existing alternator is a Prestolite type, use the part number, voltage, amp rating, and pulley specification together when checking suitability.

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 BLD3314GHPLX100 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 Weight 13.2kg, Product Group 1 ROTATING ELECTRICAL, Part No. BLD3314GHPLX100, Brand OEX, Description OEX Alternator 24V 140A Prestolite plus PLX100, Adjusting Hole Diameter 1/2 UNC, Pivot Hole Diameter 13, Pulley Outside Diameter 80mm, Regulator Type Internal, Suits Unit Make Prestolite.

OEX Alternator 24V 140A Prestolite plus PLX100. Part number BLD3314GHPLX100 should be checked first. Listed voltage is 24. Listed output rating is 140. 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 10 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BLD3314GHPLX100, 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 heavy comm in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 and output 140 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.

Compatibility note: Confirm fitment using part number BLD3314GHPLX100, the Prestolite application, 24V voltage, 140A output, twin leg mount, and the listed mounting and pulley measurements before purchasing.
