Bosch Alternator 12V 70A BXD1280N

The Bosch Alternator BXD1280N is a new 12V, 70A rotating electrical unit with an internal regulator and CW rotation. It is supplied as a single-leg mount alternator with a 5 groove pulley, a 74mm pulley outside diameter, and a mount centre-to-centre measurement of 153mm.

This alternator is listed with Pin Code IR3 and a mount leg thickness of 58mm. It is designed as a Bosch unit and is supplied new, not remanufactured, which makes the part number and physical dimensions important checkpoints when comparing against the original unit.

The stated features include corrosion resistance, high-quality raw materials for long life, and a reduction drive intended to maintain continual speeds for easier starting. The unit carries a one-year warranty and is sold individually as each.

For buyers working through a replacement, the key details to match are the part number BXD1280N, the 12V electrical system, 70A output, internal regulator, CW rotation, single-leg mount, and 5 groove pulley arrangement. Those are the most useful identifiers before ordering.

Application and Buying Notes

Before ordering, confirm the existing alternator matches the Bosch part number BXD1280N, or at least the same voltage, amperage, regulator type, rotation, and pulley setup. The important numbers on this unit are 12V, 70A, IR3, 74mm pulley outside diameter, 5 groove pulley section, 153mm mount centre-to-centre, and 58mm mount leg thickness.

A 12V alternator with a 70A rating is intended to suit vehicles with the same electrical requirements, but alternators are not interchangeable by output alone. The mounting style matters here as well, because this unit is a single-leg mount and that needs to line up with the bracket arrangement on the vehicle.

The pulley details are also worth checking before fitment. A 5 groove pulley and 74mm outside diameter must match the belt system on the vehicle, otherwise belt tracking and alignment may not be correct. The listed CW rotation also needs to align with the application.

If you are replacing a failed unit, compare the old alternator carefully rather than relying only on the vehicle model name. The supplied fitment preview points to Honda Accord and Honda Prelude applications, but the safest approach is still to verify the part number, mount dimensions, and pulley specification against the original unit.

This alternator is listed as new and backed by a one-year warranty, which may suit buyers looking to avoid remanufactured parts. Even so, installation should be confirmed by a qualified technician or by direct comparison with the removed alternator if there is any doubt about the mounting or charging system configuration.

Because the fitment information provided is partial, treat the application list as a guide rather than a final confirmation. Exact compatibility depends on the full vehicle specification, and the important matching points remain the electrical rating, regulator type, rotation, pulley section, and mounting measurements.

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 BXD1280N 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.

Additional published details for cross-checking include Part No. BXD1280N, Brand BOSCH, Description Bosch Alternator 12V 70A, Mount Leg Thickness 58mm, Power Rating (Amp) 70, Pulley Section 5 Groove, Rotation CW, Voltage 12, Mount Cnt to Cnt 153mm.

Bosch Alternator 12V 70A. Part number BXD1280N should be checked first. Listed voltage is 12. Listed output rating is 70. 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 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXD1280N, 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: Please confirm compatibility by matching part number BXD1280N and checking the 12V, 70A, IR3, CW, single-leg mount, 5 groove pulley, 74mm pulley diameter, 153mm mount centre-to-centre, and 58mm mount leg thickness against the existing unit and vehicle application before ordering.
