Application and Buying Notes

Before ordering, match the part number DXA433U and compare the mounting measurements on the vehicle’s existing alternator. The key points here are the single leg mount, 58mm mount leg thickness, 165mm mount centre-to-centre, 10mm pivot hole diameter, and M8 adjusting hole diameter.

This unit is described as Denso style and suits Denso as the unit make, so the safest way to confirm suitability is to compare the old alternator side-by-side, including pulley size and section. The listed pulley outside diameter is 72mm with an AA section, and the shaft dimension is 17.

The note supplied with this alternator says the regulator is specially designed to work on active and inactive warning light circuits. It also mentions an adaptor to suit HXK-30, HXK-22, and HXK-17, which may help with installation on the correct application, but it should still be checked against the vehicle and the existing wiring setup.

The fitment preview supplied includes Toyota Land Cruiser applications across multiple model years, but the exact engine, build date, and wiring variation still need to be confirmed before purchase. Alternators can look similar while using different mounts, pulleys, and regulator arrangements, so the matching points above matter as much as the vehicle name.

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 DXA433U 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.

For part number DXA433U, 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 110 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by checking part number DXA433U, the Denso style unit type, and the listed mounting and pulley measurements against the vehicle’s existing alternator before ordering.
