Application and Buying Notes

The most important checks on this alternator are the part number DXA4142, the OEM number DXA570, and the physical mounting details. The pad mount layout, 8mm mount hole diameter, 161mm mount centre to centre, 64mm inside mounting legs, and 60mm mount leg thickness all need to line up with the vehicle’s existing unit.

This alternator is rated at 12V and 150A, so it suits vehicles that originally use that electrical setup. The internal regulator and IR115 pin code are also important identifiers, because alternators that look similar can differ in regulator arrangement and plug configuration.

The 9 groove pulley with a 58mm outside diameter is another key checkpoint. Pulley section and diameter need to match the application, otherwise belt alignment and fit can be affected. The unit is listed as new, not remanufactured, and weighs 5.88kg.

The semi-sealed brush box is intended to help minimise debris entry under minor adverse conditions, but it does not remove the need to confirm compatibility properly. For a vehicle such as a Toyota Land Cruiser application, it is still best to compare the old alternator side by side with these measurements and identifiers before fitting.

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 DXA4142 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 150A Denso Style. Part number DXA4142 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 9 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4142, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using part number DXA4142, OEM number DXA570, the Denso-style application, and all mounting and pulley measurements before purchase. Always compare the existing alternator, plug code, and belt groove count to avoid ordering the wrong unit.
