OEX Alternator 12V 120A Denso Style DXA4062

The OEX Alternator DXA4062 is a 12V, 120A unit in Denso style, supplied new and listed as a single-leg alternator with internal regulator. It is intended for applications that call for a Denso-type alternator and uses a pulley with an 84mm outside diameter and AA pulley section.

Key physical details include a 58mm mount leg thickness, 164mm mount centre-to-centre measurement, 10mm pivot hole diameter, M8x1.25 adjusting hole, and a 17mm shaft dimension. Those dimensions are useful when checking whether the alternator will physically suit the mounting arrangement on the vehicle or machine.

This unit carries part number DXA4062 and pin code IR74. It is a 12V alternator with a 120A power rating, so confirming the electrical requirement and the mounting style before ordering is important, especially where the original unit has the same Denso-style format.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, made in ISO certified factories, and backed by a nationwide warranty. The listed warranty for this alternator is 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

Before ordering, compare the part number DXA4062, the Denso-style designation, and the mounting measurements against the unit being replaced. The critical checks here are the single-leg mount, 58mm mount leg thickness, 164mm mount centre-to-centre, 10mm pivot hole, and M8x1.25 adjusting hole, because these must match the vehicle or machine mounting arrangement for a proper fit.

The electrical specification is equally important. This alternator is rated at 12V and 120A, so it should only be considered where that voltage and output level are appropriate for the application. The internal regulator also needs to match the charging system design already in place, as regulator type is one of the main compatibility points on alternators.

The pulley details should be checked carefully as well. This unit has an 84mm pulley outside diameter and AA pulley section, so the belt profile and pulley size need to suit the existing drive system. The shaft dimension is listed at 17mm, which is another useful measurement when comparing against the removed alternator.

Fitment information is only confirmed for DYNAPAC CP142, including model years 2011, 2012, 2013 and 2014. Even where a model name appears similar, it is still best to verify the exact application with the part number and physical measurements, because alternators can differ by mounting style, pulley arrangement and regulator type.

If the removed unit is the same Denso style and the mounting dimensions line up, this alternator offers a straightforward replacement path. Where any detail differs, particularly the mount type, pulley specification or regulator arrangement, the safest approach is to compare the original alternator directly 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 DXA4062 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 12V 120A Denso Style. Part number DXA4062 should be checked first. Listed voltage is 12. Listed output rating is 120. 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 DXA4062, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include DYNAPAC CP142, DYNAPAC CP142 2011, DYNAPAC CP142 2012, DYNAPAC CP142 2013. 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 using part number DXA4062, the Denso-style application, and the listed mounting, pulley and regulator details. Do not rely on model name alone; verify the replacement unit against the removed alternator before ordering.
