Denso Alternator 12V 80A DXA4065

The Denso Alternator DXA4065 is a new 12V, 80A unit with an internal regulator, supplied as a single-leg alternator for rotating electrical applications. It carries a pulley outside diameter of 76mm, a pulley section of AA, and a mount centre-to-centre measurement of 160mm.

This alternator is listed under Denso, with a weight of 5.32kg and a mount leg thickness of 58mm. The pivot hole diameter is 10mm and the adjusting hole diameter is M8x1.25, so the physical mounting points need to be checked carefully against the vehicle and the removed unit before ordering.

The stated warranty is 12 months or 20,000km, and the unit is described as a premium-cored alternator built to OE assembly benchmarks. It is also noted as being designed for heat and electrical load demands, which makes the verified voltage, amperage, and regulator type important details when comparing replacements.

Application and Buying Notes

Before ordering, compare the part number DXA4065 with the alternator being replaced, then check the mounting style, pulley setup, and electrical rating against the vehicle. The important physical checks here are the single-leg mount, 160mm mount centre-to-centre, 58mm mount leg thickness, 10mm pivot hole diameter, and M8x1.25 adjusting hole diameter.

The electrical side also matters. This unit is a 12V alternator with an 80A output and an internal regulator, so it should be matched to the vehicle’s charging system rather than selected only by appearance. The 76mm AA pulley and IR11 pin code are useful comparison points when confirming the correct unit.

If the old alternator is available, compare its body shape, mounting ears, pulley dimensions, and connector arrangement before fitting. The listed weight of 5.32kg can also help when checking whether the replacement is in the same general range as the original unit, although weight alone should not be used to confirm compatibility.

For buyers working on Toyota Land Cruiser applications, use the model and year references as a guide only and still verify the part number and mounting measurements. Alternators can differ between engine, charging, and accessory combinations, so matching the exact unit remains the safest approach.

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 DXA4065 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.

Denso Alternator 12V 80A. Part number DXA4065 should be checked first. Listed voltage is 12. Listed output rating is 80. 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 DXA4065, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number DXA4065, the 12V 80A rating, single-leg mount, 160mm mount centre-to-centre, 58mm mount leg thickness, 10mm pivot hole diameter, and M8x1.25 adjusting hole diameter against the original unit and application details before purchase.
