Application and Buying Notes

When checking this alternator for a replacement job, compare the original unit against part number MXA333, the pad mount layout, and the listed measurements of 50mm mount leg thickness, 169mm mount centre to centre, and 10 / 12 pivot hole diameter. Small differences in mounting or pulley setup can affect whether the alternator physically installs correctly.

The 12V, 100A rating is a useful checkpoint when matching the charging system output required by the vehicle. The listing also notes that the unit can be supplied in either 100Amp or 120Amp, so it is best to confirm which version is needed before placing an order. The analogue field report terminal is another detail that should be matched to the vehicle wiring arrangement.

This alternator uses an internal regulator and a 6 groove pulley with a 53mm outside diameter. Those details need to line up with the existing unit and belt setup, especially if the vehicle has been modified or if the previous alternator was replaced with a different specification. The note that it will not interchange with MXA331 is also important for parts matching.

The part is supplied new, not remanufactured, and carries a three year warranty. That gives useful buying context, but it does not remove the need to confirm fitment. The safest approach is to check the original alternator, compare the part number, and verify all mounting and pulley details 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 MXA333 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 a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN ADVENTRA, HOLDEN ADVENTRA 2005, HOLDEN ADVENTRA 2006, HOLDEN ADVENTRA 2007. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.
