Bosch Alternator 12V 80A BXD1223N

The Bosch Alternator BXD1223N is a new 12V, 80A unit supplied with an internal regulator and a single leg alternator mount. It is listed with a 4 groove pulley, 69mm pulley outside diameter, CW rotation, and a pin code of IR11, so the key electrical and mounting details are already defined before you compare it to the vehicle.

This alternator is sold as each and carries a one year warranty. The mounting details shown are a mount centre to centre measurement of 163mm and a mount leg thickness of 58mm, which are both important checks when matching the alternator to the existing bracket and drive layout.

Bosch lists this unit as a new rotating electrical component, and the stated construction features include corrosion resistance, quality raw materials for long life, and a reduction drive for easier starting at continual speeds. Those points matter when you are choosing a replacement alternator for daily use in harsh conditions.

If you are replacing an existing Bosch alternator, the part number BXD1223N, voltage of 12V, and output rating of 80 amps should be matched carefully against the old unit and the vehicle application. Those identifiers are the safest starting point before ordering.

Application and Buying Notes

Before ordering, compare the Bosch part number BXD1223N against the alternator already fitted to the vehicle. The important matching points here are 12V charging, 80A output, internal regulation, CW rotation, and the 4 groove pulley layout, because those details need to line up with the existing electrical and belt setup.

The mounting dimensions also need checking. This unit is listed with a single leg mount, 163mm mount centre to centre, and 58mm mount leg thickness. If the bracket style or spacing differs from the current alternator, the unit may not install correctly even if the electrical rating appears similar.

The pin code is IR11, which is another useful identifier when comparing terminals and plug style. When replacing a Bosch alternator, it is best to confirm the connector arrangement, pulley section, and overall physical shape against the old unit rather than relying on the output rating alone.

Fitment information supplied for this listing includes Toyota Hilux applications from 2001 through 2005. Even with that guidance, the safest buying check is to compare the vehicle details, the existing alternator part number, and the listed physical measurements before you place the order.

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 BXD1223N 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.

Bosch Alternator 12V 80A. Part number BXD1223N should be checked first. Listed voltage is 12. Listed output rating is 80. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXD1223N, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment using the part number BXD1223N, the 12V 80A specification, the IR11 pin code, and the listed mounting and pulley details before purchase. Vehicle application data should be checked against the alternator already fitted to the vehicle.
