OEX Alternator 24V 150A Prestolite Style LXA9502

The OEX Alternator LXA9502 is a new 24V, 150A alternator built in a Prestolite style and intended for applications that use an insulated return. It is listed as a twin leg mount unit with a 101mm inside mounting leg measurement and a 212mm centre-to-centre mount dimension, so those mounting points are worth checking carefully before ordering.

This alternator uses a 9 groove pulley with an 83mm outside diameter and a 22mm shaft diameter. The regulator is internal, and the note supplied with the unit identifies an ignition excite arrangement with R for warning light, which is important when matching the charging system setup on the vehicle or machine.

OEX lists this unit as suitable for Prestolite unit make applications, and the OEM number shown is 8SC3160V. It is a large frame "Loadhandler" style alternator with insulated return, so confirmation against the existing alternator’s form, wiring arrangement, mounting style, and part number remains the safest way to purchase with confidence.

Application and Buying Notes

Start with the part number and mounting layout. This alternator is identified as LXA9502, with OEM number 8SC3160V, and it has a twin leg mount, 101mm inside mounting legs, and 212mm centre-to-centre mounting dimension. If the existing unit does not match those points, the alternator may bolt up differently even if the vehicle or machine brand looks similar.

Check the electrical setup before purchase. The unit is 24V, rated at 150A, and uses an internal regulator with insulated return. The note also refers to ign excite and R for warning light, so the charging circuit and warning lamp arrangement should be compared with the machine already in service.

Pulley and shaft dimensions matter just as much as the mount. This alternator has a 9 groove pulley, 83mm pulley outside diameter, and a 22mm shaft diameter. If the belt profile, groove count, or shaft size differs from the existing alternator, the replacement may not be suitable without further confirmation.

The listed weight is 12.58kg, which can be a useful check when comparing against the old unit. The alternator is described as a large frame 'Loadhandler' style, so make sure the physical size and bracket clearance suit the installation as well as the electrical specification.

Warranty coverage is listed as 3yr Passenger and 1yr Commercial. That does not replace correct matching, but it does give a clear warranty basis once the correct application and installation have been confirmed. As always, verify the machine’s exact alternator type, part number, pulley arrangement, and return style before fitting.

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 LXA9502 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.

For part number LXA9502, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include KOMATSU 730-E8, KOMATSU 730-E8 2017, KOMATSU 730E, KOMATSU 730E 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 compatibility using the part number LXA9502, OEM number 8SC3160V, the Prestolite application details, and the recorded mounting and pulley measurements before ordering.
