OEX Alternator 12V 140A Denso Style DXA524

The OEX Alternator DXA524 is a 12V, 140A unit built in Denso style for rotating electrical applications. It is supplied new, not remanufactured, and uses an internal regulator, which makes the main electrical and mounting details important to confirm before ordering.

Key physical identifiers on this alternator include an 8 groove pulley, 62mm pulley outside diameter, single leg alternator mount, 169mm mount centre to centre, 58mm mount leg thickness, and a 10mm pivot hole diameter. The adjusting hole is M8 x 1.25, and the shaft dimension is 17mm.

This part is listed as OEX part number DXA524 and is identified as suitable for Denso units. It weighs 6.6kg and is supplied each. For buyers matching an existing alternator, those dimensions and the part number are the most useful checks before fitment is considered.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified to support engineering, testing and quality control procedures. The listed warranty is 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

When replacing an alternator, the safest approach is to compare the part number DXA524, the Denso-style unit type, and the mounting measurements against the unit already on the machine. The key measurements listed here are the single leg mount, 169mm mount centre to centre, 58mm mount leg thickness, 10mm pivot hole diameter, and M8 x 1.25 adjusting hole.

The 12V, 140A rating tells you the electrical specification of the unit, but it does not replace a physical check of brackets, pulley alignment, connector arrangement, and drive belt setup. The 8 groove pulley and 62mm pulley outside diameter are important points to confirm if you are matching an existing alternator.

This alternator is listed as new and uses an internal regulator. That matters when comparing against an older unit, because regulator type and shaft or mounting dimensions can vary even within the same general style. The shaft dimension is 17mm and the unit weight is 6.6kg.

If the machine application is already known, use it together with the part number and the mounting measurements rather than relying on appearance alone. Fitment details supplied for this unit point to John Deere applications, but the exact machine and build details should still be checked carefully before purchase.

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 DXA524 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 3yr Passenger 1yr Commercial, Mount Leg Thickness 58mm, Pivot Hole Diameter 10, Pulley Outside Diameter 62mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 169mm, Shaft Dimension 17.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA524, Brand OEX, Description OEX Alternator 12V 140A Denso Style, Adjusting Hole Diameter M8 x 1.25, Pin Code IR7, Power Rating (Amp) 140, Pulley Section 8 Groove, Suits Unit Make Denso.

OEX Alternator 12V 140A Denso Style. Part number DXA524 should be checked first. Listed voltage is 12. Listed output rating is 140. 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 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA524, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include JOHN DEERE 8100, JOHN DEERE 8100 2014, JOHN DEERE 8560, JOHN DEERE 8560 1989. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility using the OEX part number DXA524, the Denso-style designation, the 12V 140A specification, and the listed mounting and pulley dimensions before ordering.
