Denso Alternator 12V 60A DXA4156

The Denso Alternator DXA4156 is a new 12V, 60A unit supplied as each, with a one year warranty and a single leg mount arrangement. It carries a mount leg thickness of 58mm, a pivot hole diameter of 10mm, an adjusting hole diameter of M8x1.25, and a mount centre-to-centre measurement of 164mm.

This alternator uses an internal regulator and a B section pulley with an outside diameter of 82mm. The unit is listed at 4.42kg and is described as a compact, lightweight design, which can matter when you are matching brackets, drive alignment, and surrounding component space.

The part number is DXA4156 and the pin code is IR11. The note against the unit states it has a non-active L lamp terminal, so it is worth checking the vehicle’s charging lamp circuit and the original unit details before ordering. It is also described as a high output version for DXA4155.

The listed fitment references include Toyota Echo and Toyota Industrial applications, as well as Komatsu FD25 references. Because alternators can differ by pulley, terminal layout, shaft size, and mounting points, the safest approach is to confirm the part number and all physical measurements before purchase.

Application and Buying Notes

Before buying, compare the part number DXA4156 with the unit you are replacing and check the key measurements: 58mm mount leg thickness, 10mm pivot hole diameter, M8x1.25 adjusting hole, and 164mm mount centre-to-centre. These details are often what separates a correct fit from a unit that is close but not right.

The pulley setup also needs to be matched carefully. This alternator has an 82mm outside diameter pulley with a B section profile, and the note advises that some applications may need the original pulley. It also states to check shaft size, which is especially important when the belt line or hub arrangement differs from the original unit.

The alternator is listed with a non-active L lamp terminal. That means the warning lamp wiring should be checked against the vehicle’s original charging system before fitting, rather than assuming every application uses the same terminal arrangement.

If you are cross-checking against a Denso replacement, the pin code IR11, internal regulator, and single leg mount are useful identifiers to confirm alongside the vehicle application. For industrial equipment and forklifts, the mounting pattern and electrical connection details are just as important as the model name.

The listed fitment references include Toyota Echo, Toyota Industrial variants, and Komatsu FD25 references, but alternators can vary within the same model family. Use the application details and the physical measurements together, especially where the note indicates an adaptor is available to suit HXK-30, HXK-22, and HXK-17.

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 DXA4156 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. DXA4156, Brand DENSO, Description Denso Alternator 12V 60A, Adjusting Hole Diameter M8x1.25, Pin Code IR11, Power Rating (Amp) 60, Pulley Section B, Suits Unit Make Denso.

Denso Alternator 12V 60A. Part number DXA4156 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 B. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4156, 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.

Compatibility note: Confirm fitment using part number DXA4156, the 12V 60A specification, the single leg mount dimensions, pulley details, and the terminal note before ordering. Model names and year references can help narrow the search, but the final check should always be against the unit in hand and the vehicle’s mounting and wiring arrangement.
