The OEX DXA9130 is a new 24V alternator rated at 60 amps and built in a Delco 30SI style. It is listed with an internal regulator, twin leg mount, insulated return, and a brushless unit design, so the key physical and electrical details are already defined before you compare it to the unit in the machine.

Mounting and dimensional checks matter with this alternator. The inside mounting legs are 101mm, the centre-to-centre mount measurement is 198mm, and both the adjusting hole and pivot hole are 13mm. The shaft diameter is 22mm, which should be checked against the existing unit as part of any replacement decision.

This alternator is supplied as an OEX product, with sourcing from OEM and aftermarket suppliers and factory support through ISO9001 certified production. The listed warranty is 3 years for passenger use and 1 year for commercial use, which gives you a clear reference point when selecting a replacement for equipment that uses a 24V charging system.

Application and Buying Notes

Before ordering, match the part number DXA9130 and compare the physical mount details on the existing alternator. The important checks here are the 24V system voltage, 60A output rating, 101mm inside mounting legs, 198mm centre-to-centre mount, 13mm adjusting and pivot holes, and the 22mm shaft diameter.

The Delco 30SI style and twin leg mounting arrangement are useful identifiers, but they should be treated as identifiers rather than a guarantee of interchange. If the old unit differs in shaft size, mounting spacing, regulator type, or return arrangement, the alternator may not be a direct replacement even if the machine family appears similar.

This unit is a brushless alternator with an insulated return and internal regulator. Those details can affect how the unit connects and operates in the charging system, so confirm the original setup on the machine before purchase. At 12.5kg, it is also worth comparing the physical layout carefully to the unit being removed.

The listed fitment references include CASE IH A8000 AUSTOFT and a range of CATERPILLAR applications such as 12H, 160M, 16H, 24H, 330C, 330D, 330DL, 330DLN, 336D, 336DL, 637G, 777D, 785C, 785D, 793C, 793D, 797B, 797D, 814FII, 973C, 973D, and 973DWH. Use those references as a guide only and verify the exact application details against the machine and the alternator currently fitted.

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 DXA9130 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.

OEX Alternator 24V 60A Delco 30SI Style. Part number DXA9130 should be checked first. Listed voltage is 24. Listed output rating is 60. 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. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA9130, 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 60 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by matching part number DXA9130, the 24V 60A rating, and the mount and shaft dimensions against the alternator removed from the machine. If the original unit differs in mounting, regulator, or return arrangement, check carefully before ordering.
