OEX Alternator 24V 85A Denso Style DXA4047

The OEX Alternator 24V 85A Denso Style, part number DXA4047, is a new alternator sold each and suited to Denso-style applications that call for a 24 volt, 85 amp unit. It uses an internal regulator and is identified with pin code IR11, so checking the electrical setup against the original unit is an important first step before ordering.

Physically, this alternator has a single leg mount, 58mm mount leg thickness, 168mm mount centre to centre, a 10mm pivot hole diameter and an M8x1.25 adjusting hole diameter. The pulley outside diameter is 74mm, the pulley section is AA, and the shaft dimension is 17mm. Those measurements are the key points to match when comparing against the original alternator.

This unit weighs 5.84kg and is backed by a 3 year passenger / 1 year commercial warranty. OEX positions its alternator range around quality, reliability and testing control, with ISO9001 certified factories supporting the manufacturing process. For buyers replacing a failed charging unit, the most useful checks remain the part number, voltage, amperage, mounting style and pulley details.

Application and Buying Notes

When replacing an alternator, the safest approach is to match the part number DXA4047, the 24V electrical system, and the 85A output before anything else. The mounting layout also matters here: this unit is a single leg mount with a 58mm mount leg thickness, 168mm centre-to-centre measurement, 10mm pivot hole diameter and M8x1.25 adjusting hole diameter.

The pulley and shaft measurements are just as important on Denso-style alternators. This model uses a 74mm outside diameter pulley with AA pulley section and a 17mm shaft dimension, so the original pulley arrangement should be checked carefully against the vehicle’s existing unit before fitting.

Although the fitment data points to several Hino, Holden, Toyota and UD Trucks application groups, the safest buying method is still to confirm the original alternator against the vehicle and compare the mounting points, pulley profile and regulator type. A Denso-style alternator can look similar to another unit, but the electrical and mechanical details need to line up for a proper replacement.

If the old alternator is missing, damaged or not readable, use the vehicle application, part number DXA4047 and the listed dimensions together rather than relying on appearance alone. The unit is new and covered by a 3 year passenger / 1 year commercial warranty, but correct identification remains the buyer’s responsibility before installation.

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 DXA4047 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 Product Group 2 ALTERNATORS, Part No. DXA4047, Brand OEX, Description OEX Alternator 24V 85A Denso Style, Adjusting Hole Diameter M8x1.25, Pin Code IR11, Power Rating (Amp) 85, Pulley Section AA, Suits Unit Make Denso.

OEX Alternator 24V 85A Denso Style. Part number DXA4047 should be checked first. Listed voltage is 24. Listed output rating is 85. 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 AA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4047, 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 85 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CHIRON HINO RB8, CHIRON HINO RB8 2012, HINO 300 SERIES, HINO 300 SERIES 2004, HINO 300 SERIES 2005, HINO 300 SERIES 2006. 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 compatibility by matching part number DXA4047, 24V system requirements, 85A output, Denso-style application, internal regulator, single leg mounting and the listed pulley and bracket dimensions against the original alternator and vehicle application details.
