Application and Buying Notes

The most reliable way to confirm this alternator is by matching the part number BXH1241A, the internal regulator type, and the single-leg mount arrangement. The listed 12V, 85A output should also align with the vehicle’s original charging system requirements.

Physical measurements matter here. Check the 183mm mount centre-to-centre, 51mm mount leg thickness, 10mm pivot hole, 8mm adjusting hole, and 56mm 6 groove pulley before fitting. These dimensions help avoid problems with alignment and bracket compatibility.

Because the supplied fitment references span multiple Holden, HSV and Toyota Lexcen applications, it is best to compare the alternator against the original unit already in the vehicle. Matching the pin code IR110 and confirming the pulley section can save time at installation.

This alternator is listed as new and carries a one year warranty, which is useful for buyers wanting a replacement unit rather than a remanufactured part. Even so, the vehicle should still be checked carefully for the correct mounting style, connector arrangement, and belt configuration before purchase.

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 BXH1241A 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.
