Application and Buying Notes

When checking this alternator against an existing unit, the main identifiers to compare are part number DXA423, the 12V system voltage, and the 50A output rating. The physical fit also matters, so confirm the twin leg mount, 67mm inside mounting legs, 156mm mount centre to centre, 8mm pivot hole diameter, and M8x1.25 adjusting hole diameter before ordering.

This alternator is listed as a Denso style unit with an internal regulator and a B section pulley measuring 76mm outside diameter. Those details are important because a unit can look similar yet still differ in pulley section, regulator arrangement, or mounting geometry. Matching those items to the existing alternator is the safest way to avoid avoidable downtime.

The fitment information supplied points to Toyota Industrial applications including 02-7FD35, 3FG25, 4SDK10, 5SDK10, 5SDK11, 5SDK9, FG25, and Toyota Industrial Forklift listings. Even where the application name looks familiar, confirm the machine details and the original alternator markings, as industrial equipment can change across production runs and service histories.

If you are replacing a failed alternator, it is also worth checking the shaft dimension of 15 and the pulley section before finalising the order. The unit weight is 4.4kg, which may help when comparing with the removed alternator during inspection or parts matching. Where there is any uncertainty, use the original part number and physical measurements together rather than relying on appearance alone.

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 DXA423 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 DXA423, 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 50 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility by matching part number DXA423, the Denso style application, and the measured mounting and pulley details against the existing alternator and machine setup before purchase.
