OEX Alternator 12V 60A Denso Style DXA4053

The OEX Alternator DXA4053 is a new 12V, 60A unit in Denso style, supplied as a single-leg alternator with an internal regulator. It suits Denso applications and uses a C-section pulley with a 75mm outside diameter, so matching the mounting and drive setup is important before ordering.

Key dimensional details include a 58mm mount leg thickness, 155mm mount centre-to-centre, 10mm pivot hole diameter, M8 adjusting hole diameter, and a 15 shaft dimension. The unit weighs 3.8kg, which is useful when comparing against the removed alternator or checking installation access on the vehicle or machine.

This alternator is listed with part number DXA4053 and pin code IR74. The note also flags an active lamp circuit and an adaptor to suit HXK-30, HXK-22 and HXK-17, so those details should be checked carefully against the existing wiring and connector arrangement before purchase.

Application and Buying Notes

Before ordering, compare the alternator type, mount style and key measurements against the removed unit. The important checkpoints here are the single-leg mount, 58mm mount leg thickness, 155mm centre-to-centre spacing, 10mm pivot hole, M8 adjuster hole and 75mm C-section pulley. If any of those differ, the part may not suit your application even if the vehicle or machine family looks similar.

The internal regulator and active lamp circuit note matter because electrical control and warning light setup can vary between machines. This alternator is listed as Denso style and suits Denso applications, so confirming the existing alternator branding, connector layout and lamp circuit arrangement is sensible before fitment.

The listed applications cover a broad mix of machinery and industrial equipment rather than a single passenger vehicle range. That means part number matching is especially important. DXA4053 and the IR74 pin code are useful references when comparing against your current unit, invoice records or parts catalogue.

Where an adaptor is mentioned for HXK-30, HXK-22 and HXK-17, check whether your current connection style needs one of those arrangements. The note does not replace a physical comparison of the plug, regulator and lamp circuit details, and those items should be confirmed on the vehicle or machine before finalising the order.

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 DXA4053 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 3.8kg, Product Group 1 ROTATING ELECTRICAL, Part No. DXA4053, Brand OEX, Description OEX Alternator 12V 60A Denso Style, Adjusting Hole Diameter M8, Pin Code IR74, Power Rating (Amp) 60, Pulley Section C, Suits Unit Make Denso.

OEX Alternator 12V 60A Denso Style. Part number DXA4053 should be checked first. Listed voltage is 12. Listed output rating is 60. 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 C. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4053, 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 60 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CATERPILLAR 301.5, CATERPILLAR 301.5 1999, CATERPILLAR 301.5CR, CATERPILLAR 301.5CR 2003, CUMMINS B5.9-C, DYNAPAC PL350. 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: Confirm fitment using part number DXA4053, pin code IR74, the Denso style specification, and the listed mounting and electrical details. If your removed alternator does not match the 12V, 60A, single-leg, internal-regulator configuration, check the application carefully before buying.
