Application and Buying Notes

For fitment, the most reliable checkpoints here are the Bosch style application, the OEX part number BXA020, the internal regulator, and the mounting measurements of 62.5mm mount leg thickness and 174mm centre to centre. These details matter because alternators can look similar while differing in regulator function or mount layout.

The unit is rated at 12V and 180A, so it suits buyers replacing an alternator with matching electrical requirements rather than choosing by appearance alone. The supplied note specifically recommends confirming by OE number, which is especially important when regulator functions vary between applications.

The pulley arrangement also needs attention. This alternator has a 7 groove pulley and is fitted with a clutch style pulley, so belt type and pulley style should be checked against the vehicle setup before purchase. The 49mm pulley outside diameter and 10mm adjusting hole diameter are useful confirmation points when comparing the replacement part.

If you are cross-checking against an existing unit, compare the part number BXA020, pin code IR148, and the pad mount configuration with the removed alternator. That approach gives a better match than relying on vehicle shape or generic Bosch style descriptions 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 BXA020 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 BXA020, 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 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching OE number, part number BXA020, Bosch style application details, internal regulator type, and the listed mounting and pulley measurements before ordering.
