Application and Buying Notes

Before buying, confirm that your existing alternator matches the Bosch style layout, because this unit is described as a 12V, 70A alternator with a single leg mount and internal regulator. The key dimensions to check against the vehicle are the 170mm mount centre-to-centre, 56mm mount leg thickness, 10mm pivot hole, and M8x1.25 adjusting hole.

The pulley details matter just as much as the electrical rating. This alternator has a 70mm outside diameter pulley with an A section belt profile, so belt alignment and belt type need to suit the vehicle arrangement. The shaft dimension is listed as 17, which is another practical checkpoint when comparing against the removed unit.

If you are replacing a failed alternator, compare the part number BXA030 and the pin code IR165 with the original unit where possible. The listing is for a new alternator, not a remanufactured unit, and the stated 70A output should be considered alongside the vehicle’s charging needs and original specification.

The broad application list should be treated as a guide, not a guarantee. Vehicles shown in the fitment data include several Holden, HDT and HSV applications as well as some New Holland, Peugeot, Skoda, Toyota, and Volvo Construction entries, but the safest approach is always to confirm the physical mount, pulley, and connector arrangement 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 BXA030 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 BXA030, 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 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching the part number BXA030, the Bosch style application, and the measured mounting and pulley details against your original alternator before ordering.
